Background: Eagle syndrome with repeated transient disturbances of consciousness is uncommon, with only a few reported cases. Here, the authors report a rare case of Eagle syndrome with repeated transient disturbances of consciousness in a specific head position, diagnosed using digital subtraction angiography (DSA) with head rotation., Observations: A 74-year-old man experienced several episodes of transient disturbance of consciousness. When he stared downward toward the left, he experienced transient tremors in the right upper and lower limbs and a transient loss of consciousness. Magnetic resonance imaging failed to identify the cause. DSA performed with external head rotation and leftward flexion revealed a delay of blood flow distal to the cervical portion of the left internal carotid artery caused by compression from the left styloid process. A superficial temporal artery-middle cerebral artery (STA-MCA) bypass was required in the right cerebral hemisphere. The styloid process was removed first, as the head needed leftward rotation during surgery. Transient disturbance of consciousness did not recur after surgery. Four months later, a right STA-MCA bypass was performed., Lessons: This case highlights Eagle syndrome as a potential cause of repeated transient disturbances of consciousness. DSA with head rotation proved useful for the diagnosis. https://thejns.org/doi/10.3171/CASE24744.

Purpose: The article provides an intriguing overview with tangible historical references, accompanied by photographic material, delving into the historical context of Eagle syndrome.. It ambitiously aims to shed light on the origins of the surgeon's reflections regarding the anatomy of the styloid process. Indeed, ever since the first original article by Watt Weems Eagle, these reflections have been attributed to Pietro Marchetti (Padua, 1589-1673), an Italian surgeon, anatomist, and physician. However, it appears they should be attributed to his son, Domenico De Marchetti (Padua, 1626 - 1688)., Methods: The original book "ANATOMIA-cui responsiones ad Riolanum anatomicum Parisiensem in ipsius animaduersionibus contra Veslingium additae sunt", (Padua-ed. 1654, first edition in 1652),written by Domenico De Marchetti was examined.The Latin text was analyzed adopting a philologico-clinical approach and related to contemporary medical and anatomical knowledge [18,19]., Results: The study highlights Marchetti's meticulous analysis of the hyoid bone and its associated structures, revealing the multifaceted nature of the styloid process. Noteworthy is Marchetti's observation regarding the styloid process's connection with the hyoid bone's horns during cadaver dissections, hinting at the calcification of the stylohyoid ligament, a key factor in Eagle syndrome. Marchetti's insights during cadaver dissection are evocative both regarding the hypothesis of stylohyoid ligament calcification and concerning the concept of styloid process growth throughout a person's life., Conclusions: Marchetti's observations provide the first evidence of the continuous evolution of the styloid process throughout life and represent a valuable contribution to understanding the etiology of Eagle's Syndrome., (© 2025.

An unusual case of a patient with bilateral carotid artery dissection caused by compression from elongated styloid processes is presented. The diagnosis was overlooked 8 years earlier. Eagle syndrome, marked by an elongated styloid process, can result in cervical artery dissection, highlighting the significance of recognizing this correlation in recurrent cases, which occur more frequently than idiopathic internal carotid artery dissections., (Copyright © 2024 The Author(s).

Background: Eagle syndrome is characterized by an elongated styloid process causing mechanical stress on the internal carotid artery (ICA). The authors present the case of a patient who had cervical ICA dissection with a nonelongated styloid process., Observations: A 43-year-old man presented with left hemiparesis and hemispatial neglect. The patient underwent endovascular treatment for tandem occlusion of the M1 segment of the right middle cerebral artery and right cervical ICA. After M1 segment thrombectomy, stenting of the right cervical ICA dissection was performed. Notably, the tip of the styloid process matched the caudal end of the dissection cavity, which was located on the lateral side of the ICA, where the styloid process was located. Based on these findings, the authors concluded that mechanical stress from the styloid process caused ICA dissection. After reducing antiplatelet therapy, the styloid process was surgically removed., Lessons: Mechanical stress from a nonelongated styloid process can lead to ICA dissection-induced occlusion. In patients with cervical ICA dissection, the anatomical relationship between the styloid process and dissection site, as well as the distance between the ICA and styloid process, should be evaluated. https://thejns.org/doi/10.3171/CASE24719.

Vascular complications occurring in Eagle syndrome are seldom described. The aim of this study was to systematically review the occurrence, characteristics, and management outcomes of vascular complications occurring in Eagle syndrome. A systematic review was conducted with a search in several databases. The research question was "What characterizes Eagle syndrome with vascular complications and how should it be managed?" The initial search yielded 4145 results; 150 of these were included, reporting a total of 231 patients with vascular complications. Arterial impingement (67.5%) was more frequent than venous impingement (32.5%). The most frequent consequence of arterial impingement was stroke (46.8%), while for venous impingement it was chronic headache (68%). Seventy-nine patients underwent styloidectomy as initial treatment: 78.5% of the patients were cured and 19.0% improved, while only 2.5% showed a recurrence. On the other hand, among the 106 patients treated medically without initial styloidectomy, only 24.5% of the patients were cured, 28.3% improved, and 47.2% had a recurrence. The association of symptoms of classic Eagle syndrome with neurovascular symptoms should prompt clinicians to consider this diagnosis and to measure the styloid length. Styloidectomy is the treatment of choice to obtain the best cure rate and reduce recurrence., Competing Interests: Competing interests None., (Copyright © 2024 International Association of Oral and Maxillofacial Surgeons.

Background: Stylohyoid syndrome, also known as classical Eagle syndrome (ES), is a rare condition characterized by elongation of the styloid process (SP) or calcification of the stylohyoid chain, presenting numerous non-specific symptoms. Most papers concerning this rare condition are case reports, case studies, or retrospective studies. This retrospective study delves into the intricacies of Eagle syndrome and evaluates surgical outcomes in patients treated with minimally invasive cervical styloidectomy (MICS). Methods: We conducted a retrospective study of patients treated due to ES between September 2021 and August 2023. Ninety-seven patients were qualified for MICS. Evaluation before and after surgical treatment was conducted during follow-up visits and by a questionnaire that included various data, such as symptoms, pain intensity, evaluation of healing period, and overall patient satisfaction. The minimum follow-up period was six months. Results: After applying inclusion and exclusion criteria, eighty-four patients were qualified for further assessment. The most common symptoms that subsided completely after treatment were pharyngeal foreign body sensation and pain with dysphagia or odynophagia. The MICS procedure proved to be highly effective, with 94.2% of patients experiencing a significant reduction in pain intensity and 97.1% reporting overall success. All patients were satisfied with the aesthetic outcome of the scar. The length of SP and time onset from the first symptoms to treatment positively correlated with the number, intensity, and time required for symptoms to subside. Conclusions : Eagle syndrome should be considered in diagnosing patients with orofacial and cervical pain symptoms, as the time from occurrence of the first symptoms to treatment is crucial. MICS is highly effective and has a low rate of complications in treating ES. Potential scar formation should not be a significant factor when deciding between the intraoral and external approaches.

Background : Impingement of an elongated styloid process (ESP) or calcified stylohyoid ligament on surrounding neck structures defines Eagle syndrome. The vascular variant, also called stylocarotid syndrome, results from impingement of vascular structures and remains poorly known among physicians. Research Design : We report our own experience and review the literature in order to clarify the diagnostic and therapeutic management. Patients with vascular events in relation to an ESP and hospitalized at our institution were extracted from our databank and retrospectively reviewed. We also performed a comprehensive review of the literature on Eagle syndrome using PubMed® and Google Scholar, analysing the presentation, management, and follow-up. Results : We report five cases of the vascular variant of Eagle syndrome: one carotid perforation, one focal arteriopathy, one with both acute and chronic dissection and two acute internal carotid dissection. Vascular compression, whether permanent or transient, is also reported in the literature. Management varies, although styloidectomy is deemed appropriate for symptomatic compression, while stenting is preferred in cases of perforation. Conclusions : A common definition of Eagle syndrome is required for better diagnosis and management. The choice of styloidectomy is understandable for compression but remains to be investigated in other cases., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Eagle syndrome is defined as an elongated styloid process (ESP) that compresses nearby vasculo-nervous structures. The vascular variant of Eagle syndrome can lead to neurological symptoms including syncope, transient ischemic attack, or stroke; however, it has also been associated with other atypical presentations, making its diagnosis challenging. This review aimed to depict the characteristics of patients with the symptomatic vascular variant of Eagle syndrome. The literature search identified 56 reported cases of vascular variants of Eagle syndrome, with a mean age at onset of 51 years (range: 15-85 years), and the male-to-female ratio was 2:4. The ESP was bilateral in 63% of the cases, and the mean length was 48 mm (range: 31-77 mm). Vascular complications were mostly represented by internal jugular vein (IVJ) stenosis ( n  = 28), followed by internal carotid artery (ICA) dissection ( n  = 15). Additionally, eight cases of ICA thrombosis and two cases of severe chronic stenosis of the ICA > 90% were reported. Vascular complications may lead to cerebral ischemia due to either a thromboembolic mechanism or, less frequently, reduced blood flow. Laminar cortical necrosis, as a cerebral complication of ICA compression, was exceptionally described in one case, and such an atypical clinical presentation may be regarded as a diagnostic pitfall., Competing Interests: YB reports personal fees from BMS, Pfizer, Medtronic, Amgen, Servier, NovoNordisk, Novartis, Boehringer-Ingelheim, outside the submitted work.

Background: Atraumatic localized convexity subarachnoid hemorrhage (cSAH) is an uncommon form of nonaneurysmal subarachnoid hemorrhage characterized by bleeding limited to the cerebral convexities. Ipsilateral cSAH can result from a variety of causes, such as internal carotid artery stenosis, obstruction, and dissection, although concomitant contralateral cSAH is exceptionally rare. In this case, the initial findings of cSAH led us to discovering contralateral internal carotid artery dissection (ICAD) and an elongated styloid process (ESP). ESP is recognized as a risk factor for ICAD, which is a hallmark of Eagle syndrome. This sequence of findings led to the diagnosis of Eagle syndrome, illustrating a complex and intriguing interplay between cerebrovascular conditions and anatomical variations., Case Presentation: A 47-year-old Japanese woman experienced acute onset of headache radiating to her neck, reaching its zenith approximately two hours after onset. Given the intractable nature of the headache and its persistence for three days, she presented to the emergency department. Neurological examination revealed no abnormalities, and the coagulation screening parameters were within normal ranges. Brain computed tomography (CT) revealed right parietal cSAH, while CT angiography (CTA) revealed ICAD and an ESP measuring 30.1 mm on the left side, positioned only 1.4 mm from the dissected artery. The unusual occurrence of contralateral cSAH prompted extensive and repeated imaging reviews that excluded reversible cerebral vasoconstriction syndrome (RCVS), leading to a diagnosis of left ICAD secondary to Eagle syndrome. The patient underwent conservative management, and the dissected ICA spontaneously resolved. The patient has remained recurrence-free for two and a half years., Conclusions: Managing cSAH requires diligent investigation for ICAD, extending beyond its identification to explore underlying causes. Recognizing Eagle syndrome, though rare, as a potential etiology of ICAD necessitates the importance of evaluating ESPs. The method for preventing recurrent cervical artery dissection due to Eagle syndrome is controversial; however, conservative management is a viable option., (© 2024. The Author(s).)

Eagle syndrome is a bone disease where elongation of the styloid process leads to throat and neck pain, and in severe cases neurovascular symptoms such as syncope and neuralgia. The pathophysiology of Eagle syndrome is poorly understood with various theories having been proposed how this elongation is caused. To better understand the pathophysiology, we performed a work-up in 6 patients presenting with Eagle syndrome. Patients mainly presented with pain on turning the neck (100%), foreign body sensation (67%), tension in the neck (67%), and dysphagia (50%). The typical length of the styloid process ranges from 25 to 30 mm; however, [ 18 F]NaF (sodium fluoride) PET/CT showed elongated styloid processes with an average length of 52.1 ± 15.6 mm (mean ± SD) with increased turnover at the base of one of the styloid processes. The removed styloid processes were further examined by histology, micro-CT, quantitative backscatter electron imaging (qBEI), Fourier transform infrared spectroscopy (FTIR), and circularly polarized light imaging. Histology revealed one case of a fractured styloid process healing through callus formation and one case of pseudarthrosis. Bone mineral density and mineralization was similar in the styloid processes when compared to cortical bone samples derived from the mandibular bone of different patients. Circular polarized light microscopy showed a collagen orientation in the styloid process comparable to the cortical bone samples with a distinct separation of collagen structure between the mineralized structure and the surrounding soft tissue with FTIR analysis demonstrating a typical composition of bone. This altogether suggests that the elongated styloid processes in Eagle syndrome are mature bone, capable of endochondral repair, possibly growing from the base of the process through endochondral ossification, rather than being a form of secondary calcification of the stylohyoid ligament as previously postulated., Competing Interests: No authors have conflicts of interest to disclose., (© The Author(s) 2024.

A 42-year-old male presented with 3-month history of constant right-sided frontal headaches, severe right-sided intermittent sharp jaw pain, odynophagia, globus pharyngis, and worsening episodes of blurry vision in his right eye. Cervicocerebral angiography demonstrated a prominent, 4 cm right sided styloid process with close proximity to the right internal carotid artery (ICA). The patient was referred to otorhinolaryngology for styloidectomy and continued care.

Objective: The purpose of this study is to describe both the common and uncommon symptoms associated with Eagle syndrome and share our experience treating a large group of patients with surgical intervention, primarily intraoral excision of the calcified stylohyoid ligament., Methods: This retrospective case series included 56 patients at least 18 years of age or older with a diagnosis of Eagle syndrome. All operations were conducted by a single surgeon at a tertiary medical center from 2015 to 2022. Charts were reviewed for demographics, prior medical/surgical history, symptoms, imaging results, operative details, and follow-up history. A phone survey inquired about presenting symptoms and symptom resolution following surgery., Results: The most common areas of pain were the ear (64.3%), underneath the angle of the mandible (50%), throat (46.4%), and neck (30.4%). Over 70% of patients reported tinnitus, dysphagia, and pain that were exacerbated by head rotation. Fifty-one of the 56 patients underwent surgical treatment, 92.2% via intraoral and 7.8% via cervical approaches. All patients (100%) reached in a phone survey stated that their symptoms resolved or improved after surgery., Conclusion: Eagle syndrome typically presents with common symptoms. However, healthcare providers must also be vigilant for less common manifestations, such as seizures or episodes of dizziness/fainting. These may be caused by calcification of the stylohyoid ligament. Intraoral surgical resection of the calcified ligament is a safe and effective treatment for most patients., Level of Evidence: Level 4., (© 2024 The Author(s).

Background: Eagle syndrome is caused by an elongated styloid process affecting carotid arteries and cranial nerves. Pain, dysphagia, tinnitus, paresthesia (classic subtype), and neurovascular events (vascular subtype) may be triggered by head movements or arise spontaneously. However, Eagle syndrome remains underappreciated in the neurological community. We aimed to determine the most common neurological and non-neurological clinical presentations in patients with Eagle syndrome and to assess the clinical outcome post-surgical resection in comparison to non-surgical therapies., Methodology: We conducted a systematic review of patient-level data on adults with Eagle syndrome, following PRISMA guidelines. We extracted data on demographics, presenting symptoms, neurological deficits, radiological findings, and treatments, including outcomes and complications, from studies in multiple indexing databases published between 2000 and 2023. The study protocol is registered with PROSPERO., Results: In total, 285 studies met inclusion criteria, including 497 patients with Eagle syndrome (mean age 47.3 years; 49.8% female). Classical Eagle (370 patients, 74.5%) was more frequent than vascular Eagle syndrome (117 patients, 23.5%, p < 0.0001). Six patients (1.2%) presented with both variants and the subvariant for four patients (0.8%) was unknown. There was a male preponderance (70.1% male) in the vascular subtype. A history of tonsillectomy was more frequent in classic (48/153 cases) than in vascular (2/33 cases) Eagle syndrome (Odds Ratio 5.2, 95% CI [1.2-22.4]; p = 0.028). By contrast, cervical movements as trigger factors were more prevalent in vascular (12/33 cases) than in classic (7/153 cases) Eagle syndrome (Odds Ratio 7.95, 95% CI [2.9-21.7]; p = 0.0001). Headache and Horner syndrome were more frequent in vascular Eagle syndrome and dysphagia and neck pain more prominent in classic Eagle syndrome (all p < 0.01). Surgically treated patients achieved overall better outcomes than medically treated ones: Eighty-one (65.9%) of 123 medically treated patients experienced improvement or complete resolution, while the same applied to 313 (97.8%) of 320 surgical patients (Odds Ratio 1.49, 95% CI [1.1-2.0]; p = 0.016)., Conclusions: Eagle syndrome is underdiagnosed with potentially serious neurovascular complications, including ischemic stroke. Surgical treatment achieves better outcomes than conservative management. Although traditionally the domain of otorhinolaryngologist, neurologist should include this syndrome in differential diagnostic considerations because of the varied neurological presentations that are amenable to effective treatment., Competing Interests: The authors declare that they have no competing interests., (© 2024 Hassani et al.)

Background/aim: The styloid process (SP) becomes clinically relevant when it shows enlargement (>30 mm) in the sense of an elongated SP (ESP) and/or increasing calcification leading to Eagle Syndrome (ES). Panoramic radiograph (PR) or computed tomography (CT) are part of the routine diagnostics in ES. Currently, CT is considered the gold standard. The aim of this study was to investigate the accuracy in the diagnostics/measurements of SP/ESP throughout a comparative study between PR and CT. Furthermore, in addition to measuring established parameters, this study aimed to determine the currently unexamined width in the base and tip of the SP., Patients and Methods: The present study examined the radiological findings of bilateral SP in 100 patients who received both PR and CT on the same day. Measurements of the length of the SP and width at the basis and tip were performed. Furthermore, calcification patterns, Langlais classification and the prevalence of ESP were analyzed., Results: There was a highly significant correlation between PR and CT measuring SP for every parameter. Males showed significantly longer SP than females among the age group between 18-75 years. The results of the length measurements of the SP (male: right SP=32.98 mm; left SP=35.21 mm; female: right SP=30.31 mm; left SP=30.92 mm) significantly exceeded the values of comparable studies., Conclusion: Consequently, it can be concluded that PR provides accurate measurements when compared to CT for measuring and diagnosing SP/ESP/Eagle syndrome. This study was one of the first to examine the width of the SP in the base and tip, thus these measurements can serve as a baseline for further studies. Since the mean lengths of SP exceeded 30.0 mm in the present study, these findings raise the question of whether the cut-off of 30.0 mm is adequate for the diagnosis of ESP., (Copyright © 2024, International Institute of Anticancer Research (Dr. George J.

Background/purpose: Differential screening is a complex process in chronic pain conditions. There is significant uncertainty that surrounds the pathophysiology of many chronic pain syndromes that may lead to misdiagnosis and treatment failures. Such differential screening is even more challenging where there is regional overlapping from surrounding tissues. This case report chronicles the differential screening and treatment of a patient with sternocleidomastoid syndrome (SCMS) originally diagnosed as Eagle's syndrome (ES)., Case Description: A 55-year-old woman, referred to a physical therapist (PT) by an ear, nose and throat (ENT) physician with the diagnosis of ES. The patient complained of yearlong left-sided otalgia, blurred vision, excessive lacrimation, dysphagia, hyperesthesia on the left side of the face, unilateral temporal headaches, and both left mandibular and anterior neck pain., Outcomes: The PT examination revealed the patient did not exhibit hallmark findings for clinical confirmation of ES and instead demonstrated multiple signs consistent with SCMS., Discussion: Manual therapy techniques and therapeutic exercises resolved the patient's year-long chronic symptoms within 6 sessions.

Objectives: The aim of the study is to conduct a systematic review of the existing literature on styloidectomy performed through transoral robotic surgery (TORS) in Eagle syndrome (ES)., Design and Setting: Two independent reviewers (RC and AC) conducted a systematic review of PubMed and Embase databases, seeking articles on TORS performed for ES treatment. The search was conducted in July 2023. The review was carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines., Participants: The review included a total of 17 adult patients, comprising 12 females and 5 males, with an average age of 52.2 years, all diagnosed with ES., Main Outcome Measures: For each patient, we assessed the overall length of the styloid process, the affected side, total intervention duration, hospitalization duration, pre and postoperative Visual Analogue Scale (VAS) scores, and the presence of minor and major complications., Results: We identified 4 articles describing 17 instances of TORS as a surgical treatment for ES in the literature, totaling 18 styloidectomies. The mean age of the patients was 52.2 years, with 12 females and 5 males. The average operation time, inclusive of the docking phase, was 68.8 minutes. Sixteen patients (94.1% of the total) experienced complete symptom disappearance or near-complete resolution after surgery. One patient (5.9%) showed improvement categorized as 'non-meaningful.' Only one case of minor complication was reported among the 17 procedures (5.9%)., (© 2024 John Wiley & Sons Ltd.)

Key Clinical Message: Contraindications of spinal manipulative therapy (SMT) have been proposed, which mandate rigorous control for its safe practice when manipulating the upper spine. Here, we report a vascular complication of Neck Manipulation in Eagle syndrome (ES) patient., Abstract: SMT is used to treat musculoskeletal conditions such as back pain and neck pain by applying force to the spinal joints. Here, we report a rare but devastating complication of SMT, where a young male patient, 22 years old, with ES, had a large pseudoaneurysm from the internal carotid artery (ICA) after SMT from an unlicensed practitioner, treated successfully with endograft. Clinicians administering SMT should consider an elongated styloid process as a potential contraindication to this therapy., Competing Interests: None to declare., (© 2024 The Authors.

Objectives: Transoral robotic surgery (TORS) is gaining popularity and has been introduced for the treatment of Eagle syndrome. This review aims to evaluate the safety and efficacy of TORS for the treatment of Eagle syndrome. Methods: A systematic review of the English language literature using multiple databases was completed for studies describing TORS for Eagle syndrome. The quality of studies and risk of bias were evaluated using the MINORS scoring system. Results: Out of 1495 articles screened, 4 studies met criteria for inclusion in the final analysis. Across all studies, there was a 100% surgical success rate. In total, every patient had some level of symptom improvement with 84% of patients having complete symptom improvement and 16% having partial improvement. Reported estimated blood loss averaged 12.5 mL. A total of 94.7% of patients had no surgical complications and no cases were complicated by postoperative bleeding. Operative time averaged 65 minutes. The average length of stay was 2.1 days. A total of 92% of patients resumed their diet on postoperative day 1, with the remainder resuming on postoperative day 2. MINORS criteria scoring suggested moderate risk of bias in all studies. Conclusion: Based on limited quality evidence, this review suggests that TORS is a safe and effective surgical approach in the treatment of Eagle syndrome with low complication rates. Further large-scale prospective studies are warranted., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Eagle syndrome (ES) was first described in 1937, to characterize elongation of the styloid process. It is rarely encountered by neurosurgeons but does present the potential for vascular sequelae and neurological complications., Demonstrative Cases: We discuss three patients with uncommon presentations of neurovascular compromise with uncommon symptomatology, secondary to ES. Their management ranged from retrospective diagnoses following self-limited events, antiplatelet therapy, and endovascular and surgical interventions., Discussion: While traumatic fractures, chiropractic manipulation, and history of prior neck surgery have been implicated as the etiologies for ES, congenital cases are common. The styloid process intimately interplays with adjacent neurovascular and nervous structures; its elongation can cause symptoms in 10% of patients., Conclusion: Awareness of this potentially dangerous but rare disease - more commonly seen by our otolaryngology colleagues - may help reduce diagnostic delays when an elongated styloid process is the cause, as surgery may be required.

Background: Eagle syndrome, an uncommon condition, causes symptoms due to neural and/or vascular compression from an elongated styloid process or calcified stylohyoid ligament and can also complicate other planned surgical procedures., Observations: A 42-year-old female with loss of balance, dizziness, and ataxic gait underwent cranial magnetic resonance imaging (MRI), revealing a right-sided Koos grade IV vestibular schwannoma. Initially, a retrosigmoid craniotomy for tumor resection was planned. However, preoperative MRI and computed tomography (CT) showed a dilated right-sided mastoid emissary vein, tortuous scalp and paraspinal veins, and bilateral elongated styloid processes. CT angiography and digital subtraction angiography indicated Eagle syndrome-related compression of both internal jugular veins and concurrent occlusion of the left internal jugular vein at the jugular foramen. Consequently, given the risk of damaging venous structures, Gamma Knife radiosurgery was chosen over resection., Lessons: This case highlights the importance of adapting treatment plans based on patient-specific anatomical and pathological factors. In situations in which traditional surgery poses risks to sensitive structures such as the venous system, alternative approaches like radiosurgery offer safer yet effective options. Comprehensive risk-benefit evaluations are crucial for such decisions.

Background: The external carotid artery (ECA) is typically regarded as coursing between the styloid muscles to continue into the parotid space. The anatomical possibility of an ECA with an ascending parapharyngeal trajectory continuing posteriorly to an elongated styloid process (ESP), thus retrostyloid, to the parotid space is overlooked. It was, therefore, aimed to document the prevalence of this retrostyloid variant of the ECA's course., Methods: We investigated a retrospective random cohort of 160 archived CT angiograms of 97 males and 63 females aged between 47 and 76. The presence of an ESP and the retrostyloid course of the ECA were bilaterally documented., Results: An ESP was identified in 99/320 sides (30.94%), regardless of the ECA course. In the overall group, we obtained 35% null cases for the two variables on the right and 34.06% for the left. ESPs were identified in 8.75% on the right side and 10.31% on the left. The ECAs had retrostyloid courses in 6.25% on the right side and 5.63% on the left. Thus, of the 320 ECAs documented on both sides, 221 (69.06%) had no retrostyloid courses, and we did not identify any ESP in those cases. ESPs were detected in 19.06% of the sides but without retrostyloid ECAs, and retrostyloid courses of the ECAs were detected in 11.88%., Conclusions: The possibility of a retrostyloid course of the ECA should not be ignored. An ESP may misinform the surgeon about the main carotid artery located immediately deep to it., Competing Interests: The authors have no conflict of interest to declare., (Copyright © 2022, Medical University Publishing House Craiova.)

Eagle jugular syndrome is an uncommon condition caused by compression of an elongated styloid process onto the internal jugular vein. Its presentation is non-specific but may represent in severe clinical consequences including venous thrombosis and intracranial haemorrhage. Thorough understanding of local anatomy is important in understanding the pathogenesis and establishing the diagnosis. Our case reported here illustrates the use of multimodality imaging, including dynamic Computer tomography manoeuvre, in identifying the site of obstruction and guidance towards successful surgical treatment., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction  Eagle syndrome is a rare and an often misdiagnosed entity in otorhinolaryngology. Objective  To determine the efficacy of the surgical treatment for Eagle syndrome. Methods  The present prospective study included 25 patients who presented with complaints of pain in the throat, ear, and neck, as well as difficulty and/or pain while swallowing; they were assessed for Eagle syndrome. As per patient profile, we performed a clinical assessments along with orthopantomograms (OPGs), three-dimensional computed tomography (3D CT) scans, and cone beam computed tomography (CBCT). Pain was assessed pre- and postoperatively through the Numerical Rating Scale-11 (NRS-11), whose score ranges from 0 to 10. Microscopic tonsillo-styloidectomy was performed in cases in which the conservative treatment failed to relieve pain. Results  The mean age of the entire study population was of 36.08 ± 7.19 years, and the male-to-female ratio was of 1.08:1. Referred otalgia was the commonest (44%) complaint. Radiologically, out of 25 patients, 20 patients presented elongated styloid processes. The longest symptomatic styloid process measured radiographically was of 64.7 mm while the shortest was of 28.2 mm. Out of 20 patients, 12 underwent surgery. The postoperative pain assessment through the NRS-11 was performed on day 0 (3.83 ± 0.83), day 7 (1.5 ± 0.52), week 4 (0.5 ± 0.52), and week 12 (0.41 ± 0.51). By 12 weeks, 7 patients were symptom-free, while 5 patients still reported mild pain. Conclusion  Eagle syndrome associated with an elongated styloid process is not a rarity, but it often goes undiagnosed. Microscopic tonsillo-styloidectomy shows excellent results in the management of patients with Eagle syndrome., Competing Interests: Conflict of Interests The authors have no conflict of interests to declare., (The Author(s).

Objectives: This study aimed to identify the prevalence of an elongated styloid process and analyze the presence of its calcification in the Saudi population using panoramic radiographs., Methods: The Taibah Outpatient Dental Clinic's OPG radiographs for 962 patients who attended screening clinics between December 2022 and October 2023 were all included in the study. Patients' demographics, such as age, gender, and nationality, as well as radiological data, were included in the following study variables: the presence of an elongated styloid on both sides of a panoramic radiograph, right side styloid length, left side styloid length, right side distal end thickness, and left side distal end thickness., Results: The study evaluated 438 (45.5%) processes found in individuals aged 16-80 years old. The elongated process length ranged from 30.0 to 40.1 mm, and the diameter ranged from 0.81 to 7.79 mm at the origin to 0.56-3.79 mm at the end. There was no statistically significant difference in process length across genders or age groups. The diameters of the styloid bones on the left side vary significantly across genders at the start and completion of the process., Conclusion: The prevalence of elongated styloids in the studied population was 4.26%. The radiological evaluation of the styloid process is a crucial stage in dental surgery planning., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Kaaki et al.)

Background: Eagle syndrome is characterized by an elongated styloid process, which can cause acute neurological symptoms when the projection impinges on local structures. One method by which Eagle syndrome can cause acute stroke is via internal carotid artery dissection., Observations: A patient presented with acute aphasia and right-arm weakness. Imaging revealed a left internal carotid artery dissection, which was treated with stenting. Three years later, the patient presented with left-sided weakness, and imaging revealed a new right internal carotid artery dissection. Closer review of the patient's imaging revealed bilateral elongated styloid processes. The patient subsequently underwent staged bilateral styloidectomy and returned to his prior baseline postoperatively., Lessons: This case report describes a patient with Eagle syndrome who had two internal carotid artery dissections separated by several years. A literature review revealed that styloidectomy is well tolerated in patients with carotid dissection due to Eagle syndrome. Patients with carotid dissection due to Eagle syndrome remain at risk for contralateral dissection, and prophylactic contralateral styloidectomy should be considered.

(1) Background: "Eagle Syndrome", also known as "stylalgia" or a "stylohyoid chain anomaly", typically manifests with ipsilateral orofacial pain, a foreign body sensation in the throat, and ear-related symptoms. Despite these common presentations, its potential association with carotid artery dissection is not widely acknowledged. (2) Methods: This article presents an extremely rare case of a patient diagnosed with an ischemic stroke in the left hemisphere, followed by the dissection of the left internal carotid artery, initially with an unidentified cause. Subsequent examinations revealed elongated left styloid processes directly compressing the dissected artery. (3) Results: After initial treatment involving pharmacological and mechanical thrombectomy, styloidectomy restored blood flow to the internal carotid artery. The patient remained symptom-free during a 12-month follow-up. (4) Conclusions: This case emphasizes the importance of considering anatomical variations within the stylohyoid chain when assessing young individuals with neurological symptoms. Furthermore, it underscores the potential benefits of early surgical intervention in reducing the morbidity and mortality associated with this condition.

Eagle syndrome is defined as a collection of symptoms affecting the cervical and cranial regions, resulting from an elongated styloid process or ossified stylohyoid ligament encroaching on surrounding structures and causing a variety of symptoms. Classically, Eagle syndrome presents as neck, throat, or ear pain. Carotid artery dissection is a rare complication of Eagle syndrome. We report the case of a 40-year-old man who presented with bilateral internal carotid artery dissection secondary to pathological elongation of the styloid processes., (© 2023 The Authors.

Background: This work aims to review the current literature and our experience on vascular Eagle syndrome (ES) that can present misleading clinical presentations and better understand the possible therapeutic strategies., Methods: We reviewed the existing literature on PubMed from January 1, 2017, to December 31, 2022, including the sequential keywords " vascular AND Eagle syndrome ," " vascular AND styloid syndrome ," " vascular AND elongated styloid process ," " vascular AND stylocarotid syndrome ," and " Eagle syndrome AND carotid artery dissection .", Results: 38 vascular ES cases, including our experience, were analyzed. The most frequent clinical onset was hemiparesis ( n 21, 57%), but other regular clinical presentations were aphasia, loss of consciousness, amaurosis, headache, or a combination of the latter. Massive oral bleeding was reported only once in the literature before our case. Twelve patients were treated with only antiplatelet therapy, either single or double. Nine patients were treated with anticoagulation therapy only. In 14 patients, a carotid artery stent was used, associated with anticoagulation or antiplatelet therapy. In 17 cases, a styloid process (SP) resection was performed., Conclusion: ES has many clinical presentations, and carotid artery dissection resulting in oral bleeding seems rare. Literature results and our experience make us believe that when dealing with vascular ES, the best treatment strategy is endovascular internal carotid artery stenting with antiplatelet therapy, followed by surgical removal of the elongated SP to prevent stent fracture., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Surgical Neurology International.)

(1) Background: Stylohyoid syndrome, known as classical Eagle Syndrome (cES), is characterized by calcification of the stylohyoid chain with numerous nonspecific symptoms, mainly pain. This study introduces minimally invasive cervical styloidectomy (MICS). (2) Methods: MICS was performed on sixty-five patients diagnosed with classical Eagle Syndrome. Patients underwent meticulous differential diagnosis. Surgical plans were established based on the findings from neck angioCT. (3) Results: The healing process was uneventful, without significant complications. The overall success rate was 97.0%, with a follow-up of a minimum of six months. In one case, the surgery did not yield the desired improvement. In one case, a partial relapse of symptoms was observed. (4) Conclusions: MICS is a straightforward and efficient surgical treatment technique for stylohyoid syndrome.

Eagle syndrome is a rare disease characterised by symptoms associated with an elongated styloid process or calcification of the stylohyoid and stylomandibular ligament. Symptoms associated with Eagle Syndrome include orofacial and cervical pain, dysphagia, and pharyngeal foreign body sensation. Additionally, it can present with cerebrovascular symptoms due to the compression of adjacent neurovascular structures within the vicinity of the styloid process during rotation and extension of the neck. This report presents the case of a 33-year-old male with bilateral elongated styloid processes in whom the only symptom referred was recurrent syncope. The diagnosis was made years after the initial complaints and after several observations and imagings performed by different specialities. Surgical resection of the elongated process by the cervical approach was the treatment of choice. In patients with cerebrovascular symptoms, principally those induced by positional changes of the neck, Eagle syndrome should be considered in the differential diagnosis., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Breda et al.)

Eagle Syndrome is a rare condition with a variety of presentations, resulting from an enlarged styloid process or calcified stylohyoid ligament. Due to the variety of presentations, diagnosis can be difficult. In this report, we present a case of ES that presented with a constellation of neurological symptoms, including headache and visual disturbance, ultimately found to be due to cerebral sinus hypertension, exacerbated by certain movements, caused by an enlarged styloid process with calcification of the stylohyoid ligament, consistent with ES. The patient underwent styloidectomy with immediate resolution of symptoms. This case report illustrates the diagnostic quandary often posed by ES and hopes to add further understanding to its presentation and diagnosis., (© 2023 The Authors.

Eagle syndrome is a condition that can present with a wide range of clinical manifestations, including orofacial pain, altered sensation, dysphagia, tinnitus, and ear pain, and is caused by the abnormal elongation of the styloid process or the mineralization of the stylohyoid ligament. We present a case of an incidental finding of Eagle syndrome in a 48-year-old African American patient with losartan-induced angioedema. The patient complained of a foreign body sensation in his throat and mild dysphagia, and a computed tomography scan of his neck showed ossification of bilateral stylohyoid ligaments. This case report highlights the importance of being on the lookout for other pathologies when ordering imaging for primary diagnoses., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Mann et al.)

Eagle syndrome is a clinical condition that characterized by myriad of symptoms associated with the compression of neurovascular structures by an elongated styloid process. Herein we describe a rare case of Eagle syndrome who showed bilateral internal jugular venous occlusion duo the compression of the styloid process. A young man presented with headaches for six months. Lumbar puncture showed an opening pressure of 260 mmH 2 O and the cerebrospinal fluid analysis was normal. Catheter angiography revealed occlusion of bilateral jugular venous. Computed tomography venography demonstrated compression of bilateral jugular venous by bilateral elongated styloid processes. The patient was diagnosed with Eagle syndrome and suggested to undergo styloidectomy, after which he recovered completely. We emphasize that Eagle syndrome is a rare cause of intracranial hypertension and styloid resection can bring an excellent clinical outcome in patents with intracranial hypertension due to Eagle syndrome., Competing Interests: The authors declared no conflicts of interest., (© 2023 The Authors.)

Eagle syndrome is a rare condition that is characterized by, among other things, pain in the face and neck, with the majority of cases being unilateral and isolated to the lower jaw. It is not uncommon for the pain to radiate to the ear. Symptoms can be constant or intermittent and may increase with yawning or rotation of the head, causing Eagle syndrome to be frequently misdiagnosed. The objective of this report is to summarize the symptoms, diagnostic workup, necessary imaging, and management of Eagle syndrome., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Vernon et al.)

We herein report a 54-year-old man with eagle syndrome who presented with repeated episodes of syncope, especially after moving his head to a downward position. Computed tomography with contrast revealed a bilateral elongated styloid process. The left internal carotid artery was obviously compressed by the left elongated styloid processes. A transcranial Doppler examination detected a significantly decreased blood flow velocity in the left middle cerebral artery when the patient slightly lowered his head position. After surgery, the positional cerebral blood flow alteration disappeared. No further similar syncope episodes have been reported to date.

Purpose: Minor injury to head and neck is usually neglected for potential neurological consequences. We report a woman who suffered left Eagle syndrome due to styloid process fracture two years after a minor motorcycle collision., Case Report: A 53-year-old woman complained pain at her left upper neck, lower face and periauricular area after minor motorcycle collision at 2 years ago. The pain usually occurred spontaneously but was occasionally triggered or exacerbated by specific postural changes, including looking up or turning head to right side. Moreover, a foreign body sensation occurred at throat during swallowing. Physical examination provoked pain at the left submandibular area. Carotid bruit was absent. Otherwise, other neurological function was preserved. Computerized tomography revealed linear fracture at the middle of left styloid process. After inform, patient preferred conservative treatments including abortive non- steroidal anti-inflammatory drugs and an avoidance of rapid head rotations. Since afterwards, the frequency and intensity of neck pain greatly decreased and she could tolerate and maintain a normal daily living., Conclusions: Asymptomatic or paucisymptomatic styloid process fracture may be neglected in case of minor injury to head and neck. A careful evaluation of neck should be completed in traumatic individuals to reveal underlying damage and prevent further harmful consequence.

In Eagle syndrome, elongated styloid processes may provoke internal carotid dissection and pseudoaneurysm causing stroke and data regarding possible complications or long-term results of pseudoaneurysm treatment using a flow diverter are limited. We report a case of a dissection-related pseudoaneurysm in the left cervical carotid artery treated by implantation of a flow diverter. Follow-up imaging of the flow diverter showed fracture of a continuous radiopaque marker at 3 months and fracture of a second continuous radiopaque marker at 7 months, while contrasting of the vessel was preserved. At the time of angiographic control (8 months after implantation), the flow diverter and the extracranial left internal carotid artery were occluded, and the patient did not experience any symptoms throughout the period.

The present investigation summarizes relevant symptoms, differential diagnosis, imaging, and treatment options of Eagle Syndrome. A comprehensive literature review of peer-reviewed literature was employed utilizing most relevant databases. The diagnoses of Eagle Syndrome have recently increased because of increased awareness of physicians of Eagle Syndrome and the earlier identification of the cardinal symptoms of the disease. The most important symptoms are dysphagia in the setting of cervical neck pain, but there is a wide variety of symptomatology that make Eagle Syndrome a challenge to recognize and diagnose clinically. CT scan continues to be the standard of care for diagnosing Eagle Syndrome and CT Angiography has an important role in aiding diagnosis as well. Medical treatment options include steroids, antidepressants, and anticonvulsants however not all cases of Eagle Syndrome can be managed medically. Surgical approaches are varied but typically are either extraoral or transoral. This report aims to update providers on the important diagnostic criteria of Eagle Syndrome and how physicians can develop a treatment plan that addresses all the symptoms of patients with Eagle Syndrome because it can be treated safely and appropriately., Competing Interests: The authors did not receive any funding or financial support or potential sources of conflict of interests.

Objectives: This research aimed at investigating the relationship between calcification of the stylohyoid ligaments (SHLs) and odontogenic inflammatory events., Methods: Cone-beam computed tomography scans of 175 patients were retrospectively assessed for presence of SHL calcifications. Frequencies of 4 types of odontogenic inflammatory events were assessed using the same scans, namely dental extractions, root canal treatments, furcation lesions, and periapical lesions. Patients were telephone-interviewed and asked about histories of tonsillectomy and head and neck trauma. Mann-Whitney U and binary logistic regression tests were used to assess associations between SHL calcification and mean ranks of odontogenic inflammatory events., Results: Calcification of SHLs was detected in 71 (41%) and 58 (33%) patients on the right and left sides, respectively. Tonsillectomy and trauma were reported in 14% and 10% of the sample, respectively. Amongst all inflammatory events, root canal treatments were significantly associated with SHL calcification (U = 2755; Z = -2.1; P = .035). This association was independent from patient age, tonsillectomy, trauma, and other inflammatory events (odds ratio, 1.2; 95% confidence interval, 1.0-1.4; P = .036)., Conclusions: This study presents new evidence that intra-oral inflammatory events, particularly related to root canal treatments, have a stronger association with SHL dystrophic calcification than that associated with traditional predisposing factors (ie, old age, tonsillectomy, and trauma)., Competing Interests: Conflict of interest None disclosed., (Copyright © 2022 The Authors.

Objectives: An elongated styloid process may cause vascular Eagle syndrome that includes cervical carotid artery (CCA) dissection with stenosis and aneurysm formation. There are only four reported cases with vascular Eagle syndrome-related CCA dissecting aneurysm treated with carotid artery stenting (CAS). This is the first report of applying a dual-layer nitinol micromesh stent (CASPER) for vascular Eagle syndrome-related CCA dissecting aneurysm., Case Presentation: A 38-year-old man presented with a sudden onset of aphasia and right hemiplegia. Cerebral angiography demonstrated the left CCA dissecting aneurysm. The superior trunk of the left middle cerebral artery (MCA) was also occluded, and emergent thrombectomy was performed. Computed tomography with angiography (CTA) revealed that a 33 mm-long styloid process compressed the CCA at the aneurysm formation. Three weeks later, a CASPER stent was applied for the CCA aneurysm under the flow reversal system. Immediately after stent placement, blood flow in the aneurysm became stagnant, and postoperative CTA demonstrated regression of the aneurysm. The aneurysm did not recur for 6 months with no styloid process resection., Conclusions: The dual-layer nitinol micromesh stent (CASPER) was useful to treat vascular Eagle syndrome-related CCA dissecting aneurysm., Competing Interests: Conflict of interest None., (Copyright © 2022 Elsevier Inc.

Vascular compression syndromes include a group of rare vascular changes due to extrinsic compression of veins or arteries by surrounding structures. These pathologies are often underestimated due to their rarity, clinicians' poor level of knowledge, and the non-specificity of their symptoms. The best known are Eagle syndrome, thoracic outlet syndrome, nutcracker syndrome, May-Thurner syndrome, Dunbar syndrome, and popliteal entrapment syndrome. This work summarizes the main ultrasonographic characteristics, symptoms, and treatments of choice for these syndromes. Knowledge of these conditions' characteristic signs is essential for the differential diagnosis. Failure to diagnose these rare diseases can expose patients to serious complications and risks to their health.

We report a case of a 61-year-old lady presenting with several weeks of progressive left-sided weakness, and found to have a foramen magnum meningioma. She was counselled on surgical resection of the tumour, and a preoperative computed tomography angiogram (CTA) was obtained for operative planning purposes. CTA demonstrated incidental bilateral internal jugular vein (IJV) stenosis, with enlarged extracranial collateral vessels and elongated styloid processes. The main surgical concern was potential injury of the extracranial collateral vessels during operative exposure, which may compromise her intracranial venous outflow in light of the IJV stenosis. A doppler ultrasound scan of the IJVs was performed, which demonstrated that blood flow was still present through both vessels. Through careful soft tissue dissection during surgery, potential complications and injury to the extracranial collaterals were avoided. We performed a literature review of the incidence of IJV stenosis, its associated conditions, and potential surgical implications. Complications from injury to vital collateral extracranial vessels should be considered during preoperative planning in patients with anatomical variants or risk factors for IJV stenosis, as seen in this case., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Zhang et al.)

&lt;b&gt;Introduction:&lt;/b&gt; Patients often suffer from an elongated styloid process. This clinical entity is well known and is described as Eagle syndrome. The presence of this anatomical variation is not always associated with symptoms. However, there is a strong correlation between the elongated styloid process and Eagle syndrome &lt;/br&gt;&lt;/br&gt; &lt;b&gt;Aim:&lt;/b&gt; This study aims to calculate the incidence of elongated styloid processes in the Greek population, to analyze the morphometric characteristics of styloid processes, and to compare these among sexes. &lt;/br&gt;&lt;/br&gt; &lt;b&gt;Material and methods:&lt;/b&gt; This is a single-center retrospective study. All skulls were donated to the Department of Anatomy, the Ari-stotle University of Thessaloniki from January 2013 to May 2019 for research purposes. A styloid process longer than 30 mm was considered elongated. We used Welch's t-test for the statistical analysis of the data. &lt;/br&gt;&lt;/br&gt; &lt;b&gt;Results:&lt;/b&gt; The prevalence of elongated styloid processes was 35%. The average diameter was 3.32 mm and the average total length was 25.02 mm. There was no statistically significant difference between male and female skulls, though the female styloid processes were slightly longer and the male ones were slightly wider. Symmetry was recorded in 31% of skulls. Average axial angle was 650 but in 4% of cases it was less than 20&lt;sup&gt;0&lt;/sup&gt;. &lt;/br&gt;&lt;/br&gt; &lt;b&gt;Conclusions:&lt;/b&gt; The elongated styloid process is not a rare entity. Eagle syndrome should always be considered in the differential diagnosis when patients report chronic sore throat. Our anatomical findings add a new dimension to the etiopathogenesis of Eagle syndrome.

We demonstrate a safe and effective surgical technique for the operative management of Eagle syndrome, also known as stylohyoid syndrome, via transcervical styloidectomy. Fifteen patients who presented to our institution for surgical management of Eagle syndrome were included. A detailed video shows the operative techniques used to perform styloidectomy via a transcervical approach. The procedure was well tolerated without complications, and all patients were discharged on postoperative day one. Thirteen patients (87%) endorsed significant improvement or complete resolution of their presenting complaint(s), most commonly throat and neck pain/discomfort (53%), otalgia (47%), and/or tinnitus (40%). The transcervical approach for styloidectomy provides an alternative for operative access that overcomes the limitations associated with the transoral approach. It enables better exposure of the operative field, a more efficient procedure, and, in the senior author's experience, results in decreased postoperative pain, trismus, and length of hospital stay., (© 2022 Wiley Periodicals LLC.)

Ossification of stylohyoid chain corresponds to the ossification of stylohyoid ligament that can vary from thin short to thick long ossification and can be associated with other calcifications. We report in this case a bilateral non painful complete ossification of the stylohyoid complex extended to the thyrohyoidien ligament., Competing Interests: All the authors declare that there is no conflicts of interest., (© 2022 The Authors.

Elongated styloid process or calcified stylo-hyoid ligament can exert pressure on vital structures of the neck and cause symptoms of Eagle syndrome. Although it is uncommon, both can cause death by compression of neurovascular structures. We report the case of an incidental finding of an elongated styloid process at autopsy, along with its clinical and medicolegal significance. The article attempts to review the literature in this regard and on variants of styloid process., (Copyright © 2022 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.)
