Objectives: Tumors involving the vagus nerve are often clinically silent. We offer a case series with different clinical presentations and distinctive post-surgical sequelae that highlight some of the challenges associated with managing cervical vagal nerve tumors. Methods: Single-institution, retrospective review of patients with tumors involving the vagus nerve. We describe clinical presentations and postoperative sequelae of five patients who underwent surgical management of vagal nerve pathology with atypical presentation or subsequent clinical course. Results: Here, we present five patients treated at our institution for vagal tumors. In four of the five patients, the presenting symptoms resolved after surgery. Two patients presented with intractable neurogenic cough, and another two presented with autonomic symptoms, one with syncope/palpitations and the other with intractable sweating. The final patient presented with a rapidly enlarging vagal paraganglioma and developed intractable cough after resection. We present two patients with novel approach to vagal paragangliomas that underwent ligation of feeding blood supply without removing the tumor, resulting in resolution of an intractable cough in one patient and resolution of severe nighttime sweating in the other. Conclusion: Management of tumors associated with the cervical vagus nerve that present with symptoms or rapid growth poses a clinical dilemma. Consideration of the tumor origin with either enucleation of schwannomas or ligation of feeding vessels may preserve function while addressing the presenting symptoms. [ABSTRACT FROM AUTHOR]

Simultaneously diagnosing cervical sympathetic chain schwannoma, nodular goiter and parathyroid adenoma is a very rare event during clinical practice. We had the opportunity to find this unusual association on a female patient. While nodular goiter and parathyroid adenoma are more common diseases and easier to diagnose, identifying the etiology of a parapharyngeal space tumor remains a challenge and requires multiple imaging studies such as computed tomography scan, magnetic resonance imaging or angiography. A cervical sympathetic chain schwannoma, a carotid body tumor, a paraganglioma or a vagal schwannoma must be taken into account as possible diagnostic variants. Complaints such as Horner`s syndrome, hoarse voice or dysphagia may suggest a nerve originating tumor, but this is a rare situation. Only the surgical exploration is successful in detecting the tumor origin from the cervical sympathetic chain. Even so, the exact origin of the tumor cannot usually be detected without surgical exploration and removal of the piece or biopsies. Therefore, the pathological report of the specimen (adding or not immunohistochemistry tests) is mandatory to be able to confirm the diagnosis of schwannoma.

Background and Objectives: Clinical management of vagal schwannoma is a real diagnostic and therapeutic challenge because the medical history and clinical examination are often non-specific and vagal nerve injury following surgical resection still represents an unsolved problem. The aim of this paper is to provide a case series along with a diagnostic and therapeutic algorithm for vagal schwannoma of the head and neck, combining our experience with clinical evidence available in the literature. Materials and Methods: We retrospectively analyzed a series of patients affected by vagal schwannoma who were treated between 2000 and 2020. In addition, a review of the literature on vagal schwannoma management was conducted. Based on the cases described and the literature review, we made a diagnostic and therapeutic algorithm for the management of vagal schwannoma. Results: We were able to identify 10 patients affected by vagal schwannoma and treated between 2000 and 2020. All patients presented with a painless, mobile, slow-growing lateral neck mass with onset varying from a few months to years. The preoperative diagnostic workup included ultrasound (US) in nine cases, computed tomography (CT) with contrast in six patients and magnetic resonance imaging (MRI) of the neck in seven cases. All patients included in this study were surgically treated. Conclusions: Vagal schwannoma management represents a true challenge for clinicians and surgery is currently the most effective therapeutic strategy. A multidisciplinary approach through the collaboration of otolaryngologist with other specialists is desirable to develop a tailored treatment plan for the patient. [ABSTRACT FROM AUTHOR]

Background: This study evaluates the outcomes of intracapsular enucleation using the retroauricular hairline incision (RAHI) approach for treating cervical vagal schwannomas., Methods: A longitudinal study was conducted on patients with cervical vagal schwannomas. Eleven patients who underwent RAHI-based enucleation were included. Preoperative imaging was performed using contrast-enhanced MRI. Postoperative evaluations assessed pain, neurological function, cosmetic outcomes, voice, and swallowing functions., Results: Eleven patients underwent surgery. The median tumor size was 4.6 cm. The median operation time was 42 min, with minimal bleeding. Common complications were earlobe numbness (45%) and temporary vocal cord paralysis (27%), which were resolved within a year. Cosmetic satisfaction was high, with median VAS scores of nine for scars and 10 for facial deformities. No significant dysphagia was found. No recurrences were observed over a median follow-up of 79 months., Conclusions: Intracapsular enucleation using the RAHI approach is a safe and effective method for treating cervical vagal schwannomas., (© 2024 Wiley Periodicals LLC.)

Cervical vagal schwannoma is a rare clinical entity that requires a different clinical approach than other neck swellings. Magnetic resonance imaging is the preferred initial diagnostic test. Complications may arise due to vagal stimulation in unsuspecting open biopsies. Surgical excision with perioperative vagal monitoring is recommended for the treatment of vagal schwannomas.

Purpose: Different therapeutic strategies have been developed to improve surgical and functional outcome of parapharyngeal space (PPS) neoplasms. The transparotid–transcervical approach (TTa) is a valid surgical option to manage most PPS tumors. Its short- and long-term disease control and cranial nerve (c.n.) function outcomes have not been discussed extensively. Methods: All patients who underwent TTa over a 10-year period at a tertiary academic center were retrospectively reviewed. Data about preoperative imaging, clinical presentation, tumor's size, location and histology, and postoperative oncological and functional results were registered and analyzed. Results: Sixty patients matched the inclusion criteria. Most of the lesions were benign (71.7%), involved the prestyloid PPS (63.3%) and measured more than 30 mm (75%). Fifty-two (86.7%) lesions were resected en-bloc. Clear margins were achieved in 91.7% of the cases, with positive margins solely associated with malignancy (p = 0.008). Post-operative c.n. function was satisfactory, with X c.n. function significantly associated with the retrostyloid location (p =.00) and neurogenic tumors (p = 0.02). Local disease-control was achieved in 96% of the cases after a median follow-up of 46 (± 19.7–82.0 IQR) months. Conclusions: The TTa was safe and effective, achieving a satisfactory local control rate. Nevertheless, malignancies maintain a higher rate of positive margin due to their infiltrative nature and the complex anatomy of the PPS. In such cases, multiportal approaches might be more effective. However, post-operative c.n. function remained satisfactory, irrespective of lesions' size and histopathologic behavior. A higher X c.n. deficit rate was observed in retrostyloid and neurogenic lesions. [ABSTRACT FROM AUTHOR]
