Purpose: This study aims to demonstrate a correlation between cervical spine injury and location and severity of facial trauma. Methods: We did a 10-year retrospective analysis of prospectively collected patients with at least one facial and/or cervical spine injury. We classified facial injuries using the Comprehensive Facial Injury (CFI) score, and stratified patients into mild (CFI < 4), moderate (4 ≤ CFI < 10) and severe facial trauma (CFI ≥ 10). The primary outcome was to recognize the severity and topography of the facial trauma which predict the probability of associated cervical spine injuries. Results: We included 1197 patients: 78% with facial injuries, 16% with spine injuries and 6% with both. According to the CFI score, 48% of patients sustained a mild facial trauma, 35% a moderate one and 17% a severe one. The midface was involved in 45% of cases, then the upper facial third (13%) and the lower one (10%). The multivariate analysis showed multiple independent risk factors for associated facial and cervical spine injuries, among them an injury of the middle facial third (OR 1.11 p 0.004) and the facial trauma severity, having every increasing point of CFI score a 6% increasing risk (OR 1.06 p 0.004). Conclusions: Facial trauma is a risk factor for a concomitant cervical spine injury. Among multiple risk factors, severe midfacial trauma is an important red flag. The stratification of facial injuries based on the CFI score through CT-scan images could be a turning point in the management of patients at risk for cervical spine injuries before imaging is available.

Mandibular fractures are very common in maxillofacial trauma surgery. While previous studies have focused on possible risk factors related to post-operative complications, none have tried to identify pre-existing conditions that may increase the risk of mandibular fractures. We hypothesized, through clinical observation, that anatomical conditions involving poor dental contacts, such as malocclusions, may increase the risk of mandibular fractures. This work was subdivided into two parts. In the first part, Digital Imaging and Communications in Medicine (DICOM) data of four healthy patients characterized by different dentoskeletal occlusions (class I, class II, class III, and anterior open bite) have been used to develop four finite element models (FEMs) that accurately reproduce human bone structure. A vertical and lateral impact have been simulated at increasing speed on each model, analyzing the force distribution within the mandibular bone. Both vertical and lateral impact showed higher level of stress at the impact point and in the condylar area in models characterized by malocclusion. Specifically, the class III and the open bite models, at the same speed of impact, had higher values for a longer period, reaching critical stress levels that are correlated with mandibular fracture, while normal occlusion seems to be a protective condition. In the second part of this study, the engineering results were validated through the comparison with a sample of patients previously treated for mandibular fracture. Data from 223 mandibular fractures, due to low-energy injuries, were retrospectively collected to evaluate a possible correlation between pre-existing malocclusion and fracture patterns, considering grade of displacement, numbers of foci, and associated CFI score. Patients were classified, according to their occlusion, into Class I, Class II, Class III, and anterior open bite or poor occlusal contact (POC). Class I patients showed lower frequencies of fracture tha

The study aims to assess the influence on mortality of motorcycle road accidents, caused by injuries to the head, chest, abdomen, face, skin, pelvis and extremities. Road motorcycle accidents consecutively admitted to Level I Trauma Center were retrospectively analyzed. Each body site involvement was classified through Abbreviated Injury Score (AIS-98), and Comprehensive Facial Injury (CFI) score; Injury Severity Score (ISS) was also calculated. The data collected were subjected to a descriptive analysis and inferential statistic, with uni- and multivariate analysis; mortality was the main outcome examined. 1862 patients were studied. Limbs (53.9%) and Head (53.8%) are the most involved body site, facial trauma regards 19.4% of the sample. Only 4.4% of Facial injuries occurred as isolated, 71.6% were associated to Head involvement. The overall mortality was 4.6% and 80.0% of dead patients were affected by Head injury. Multivariate analysis shows that head (OR=3.06, p <0.0001), thoracic (OR=1.82, p <0.0001) and abdominal trauma (OR=1.41, p =0.019) are predicting the risk of death. Facial trauma does not directly influence mortality and, however severe and distracting it may be, becomes secondary to the management of frequently associated brain injuries. Severity scores targeted to the risk of death, such as AIS and AIS-derived, are ineffective in describing the true characteristics of facial injuries. The CFI score has been shown to predict the weight of surgical treatment and the outcome of the hospital stay, therefore its use is recommended.

Salivary gland cancers (SGCs) are rare, accounting for less than 5% of all malignancies of the head and neck region, and are morphologically heterogeneous. The diagnosis is mainly based on histology, with the complementary aid of molecular profiling, which is helpful in recognizing some poorly differentiated, borderline, or atypical lesions. Instrumental imaging defines the diagnosis, representing a remarkable tool in the treatment plan. Ultrasound and magnetic resonance are the most common procedures used to describe the primary tumour. The treatment of SGCs is multimodal and consists of surgery, radiotherapy, and systemic therapy; each treatment plan is, however, featured on the patient and disease’s characteristics. On 24 June 2022, in the meeting “Current management and future challenges in salivary gland cancers” many experts in this field discussed the state of the art of SGCs research, the future challenges and developments. After the meeting, the same pool of experts maintained close contact to keep these data further updated in the conference proceedings presented here. This review collects the insights and suggestions that emerged from the discussion during and after the meeting per se.

Pressure garment therapy is frequently used to prevent pathologic scarring, especially in burns. Less common is its use for the treatment of facial wounds. Pathologic scarring can create functional and aesthetic problems, which can have psychological implications. The aim of this study is to report our experience in the treatment of traumatic facial wounds using an elastic custom facial mask.

Complex craniofacial injuries (CFI) are induced by high-energy mechanisms of injury, resulting in the simultaneous breaking of many bones, bony displacement and often comminution, soft tissue lacerations or avulsions, and visceral consequences. They can be defined as facial injuries with a CFI score equal to or above 10. In the emergency setting, severe facial injuries can affect the patency of the airway and hemodynamic instability, so essential Damage Control procedures must be well known. These patients often have associated injuries, which can constitute real-life saving priorities. Among these, certainly the most frequent are traumatic brain injuries and cervical spine injuries. This type of patient generally requires long-lasting surgery, with a lack of a solid anatomical reference for reconstruction, a few weeks of hospitalization, and several days in ICU. The definitive treatment of complex craniofacial injuries, therefore, requires high technical skill, but mainly a solid organization of the reconstructive planning and multidisciplinary coordination of priorities and treatment sequences. Technologies and the heavy manipulation of images are nowadays indispensable tools, for a correct diagnosis and personalized surgical planning, and for increasing the level of safety and accuracy of the results. Concurrent skull base fractures and gunshot injuries represent the most complex expressions of severe craniofacial injuries, in which specific definitive treatment protocols are required for proper management.

The application of surgical navigation in oral and maxillo-facial surgery has been increasing over time. In fact, computer-assisted surgery provides real-time, precise, and accurate position and guidance during surgery. The purpose of our work is to introduce the evolution of surgical navigation in recent decades, describe some technical aspects of this technology, explore new possibilities of application of surgical navigation in oral surgery, and validate the accuracy of computer-assisted surgery. We included four patients in our sample who underwent virtual planning on the cone beam CT data set and surgical navigation using non-invasive fiducial markers. The first patient presented a dislocated orthodontic arch in the soft tissues of the cheek, while the other patients presented supernumerary and impacted dental elements. Among them, two patients were affected by craniofacial synostosis. We evaluated the accuracy of computer-assisted surgery, calculating the discrepancy between the real and virtual target. In all cases, the target registration error was less than or equal to 1 mm. We can affirm that surgical navigation is a valid tool to enhance oral surgery, guaranteeing an undoubted advantage in terms of the reliability and predictability of the results, especially in complex cases.

This research aimed to identify a new measurement to diagnose the sagittal maxillary and mandibular difference that considers the patient’s profile (soft tissue Wits appraisal: obtained by projecting points A and B on the occlusal plane and subsequently measuring the linear distance between the two points). This new measurement was compared to the conventional Wits appraisal obtained to diagnose sagittal jaw discrepancy. In total, 300 subjects (162 males, 138 females) aged between 6 and 50 years requiring orthodontic treatment were analyzed. The cephalometric tracings on the pre-treatment lateral cephalometric radiographs were obtained and the two measurements taken were the Wits appraisal and a new measurement which were both calculated and compared. The analysis of the linear correlations between the conventional Wits value and the measurement obtained on the soft-tissue were undertaken. The relevance was established at 5% (p < 0.05). The mean values were also calculated within sex and age classes, and comparisons between sexes were obtained employing the t test Student’s for independent samples. Subsequently, chi-square analysis was also utilized to verify the sex distributions in the age groups considered. The results obtained suggested that these two measurements were significantly correlated with each other, with no characteristic patterns of sex or age. These data allowed an estimation of the reference values of the new measurement (−1.9 mm and 5.4 mm for patients with Class I molar relationship) showing that the former was more variable than the latter. The new measurement could allow for an accurate evaluation of the jaws sagittal discrepancy from soft tissue analysis.

Introduction: Motorcycle accidents are one of the most frequent causes of trauma. Safety devices and helmets can influence the severity of injuries. Our retrospective study wants to evaluate the different effectiveness of Open-face and Full-face helmets in the prevention of craniofacial trauma. Materials and Methods: The sample consists of 440 patients admitted to two Level I Trauma Centres in Northern Italy, between January 2002 and February 2019, because of motorcycle-related craniofacial trauma. For each patient personal data were collected, as well as type and site of fractures, type of helmet, if worn, Comprehensive Facial Injury (CFI) score and Abbreviated Injury Score (AIS-Head) for head injuries. Inferential statistical analysis was then conducted. Results: Two hundred and eighty-eight patients wore Open-face helmets (69.7%) and 125 patients wore Full-face ones (30.3%). Mean CFI score (Standard deviation-SD) observed in patients with Open-face helmets was 7.0 (SD: 6.8) and surgery was required in 149 cases (51.7%); while it was 4.9 (SD: 6.0) in patients with Full-face helmets for whom surgery was required in 43 cases (34.4%) (P < 0.0001 and P = 0.002, respectively). Multivariate analysis shows that severity of facial trauma is a significant risk factor for head injury severity with OR 1.90 (95% confidence interval: 1.43-2.51) and P < 0.0001. Discussion: Full-face helmets are definitely considered to be more protective for facial trauma, which is also a significant risk factor for the severity of head injuries. The type of helmet chosen influences the need of surgical treatment in case of craniofacial trauma.

Aim: the purpose of this work is to present an innovative protocol for virtual planning and surgical navigation in post-oncological mandibular reconstruction through fibula free flap. In order to analyze its applicability, an evaluation of accuracy for the surgical protocol has been performed. Methods: 21 patients surgically treated for mandibular neoplasm have been included in the analysis. The Brainlab Vector Vision 3.0® software for surgical navigation has been used for preoperative surgical planning and intra-operative navigation. A post-operative accuracy evaluation has been performed matching the position of mandibular landmarks between pre-operative and post-operative CT scans. Results: the maximal discrepancy observed was included between −3.4 mm and +3.2 mm, assuming negative values for under correction and positive values for overcorrection. An average grade of accuracy included between 0.06 ± 0.58 mm and 0.43 ± 0.68 mm has been observed for every mandibular landmark examined, except for mandibular angles that showed a mean discrepancy value included between 1.36 ± 1.73 mm and 1.46 ± 1.02 mm when compared to preoperative measurements. Conclusion: a satisfying level of accuracy has been observed in the protocol presented, which appears to be more versatile if compared to closed custom-made systems. The technique described may represent a valid option for selected patients, but it cannot be considered for routine activity because of the complexity of the method, the mobility of the jaw, the necessity of surgical navigator and the long surgical learning curve that is required.

Ameloblastoma is a rare, benign, odontogenic tumor of epithelial origin, characterized by locally aggressive, expansive growth. Treatment is controversial due to the risk of relapse. The aim of this multicenter retrospective study was to evaluate the effectiveness of complete resection in cases of complex ameloblastoma, which is considered at a higher risk of recurrence. Patients who met at least one of these criteria were included: recurrence, soft-tissue involvement, complete erosion of internal/external cortical walls with involvement of the inferior margin of the mandible, and invasion of the maxillary sinus or nasal cavity. Demographic data, tumor site, type of surgery, histological features, and follow-up information were collected for each patient. The cohort included 55 patients with a mean follow-up of 108 ± 66 months. A multivariate logistic model was used to evaluate variables independently associated with relapse. There were six soft-tissue or maxillary sinus relapses, with a recurrence rate of 10.9%. Most of them arose in patients previously treated. The statistical analysis identified the maxillary location as a fundamental relapse risk factor. En bloc resection with large surgical safety margins seemed to be effective in preventing the relapses. However, complete resection was less effective in preventing recurrences in the soft tissues or maxillary sinus.

Identifying groups of patients with homogeneous characteristics and comparable outcomes improves clinical activity, patients’ management, and scientific research. This study aims to define mild, moderate, and severe facial trauma by validating two cut-off values of the Comprehensive Facial Injury (CFI) score and describing their foreseeable clinical needs to create a useful guide in patient management, starting from the first evaluation. The individual CFI score, overall surgical time, and length of hospitalization are calculated for a sample of 1400 facial-injured patients. Receiver Operating Characteristic (ROC) analysis and the corresponding Area Under the Curve (AUC) is tested, and a CFI score ≥4 is selected to discriminate patients undergoing surgical management under general anesthesia (Positive Predictive Value, PPV of 91.4%), while a CFI score ≥10 is selected to identify patients undergoing major surgical procedures (Negative Predictive Value, NPV of 91.7%). These results are enhanced by the consensual trend of Length of Stay outcome. The use of the CFI score allows us to distinguish between the “Mild facial trauma” with a low risk of hospitalization for surgical treatment, the “Moderate facial trauma” with a high probability of surgical treatment, and the “Severe facial trauma” that requires long-lasting surgery and hospital stay, with an increased incidence of Intensive Care Unit admission.

The avulsion of the impacted lower third molar is one of the most common procedures in oral surgery. Even though it is characterized by possible complications due to the lesion of lingual and inferior alveolar nerves, the intra-oral surgical approach represents the first-choice strategy when planning surgery. However, in case of ectopic tooth in the mandibular basal bone, it is appropriate to consider an extra-oral transcutaneous surgical approach. The ectopia of the inferior wisdom tooth represents a very rare clinical condition and sometimes it is even unknown by patients and dentists: further evidence of this fact is represented by the paucity of paper related to the topic that can be found in the international scientific literature. The experience of the Department of Maxillofacial Surgery of San Gerardo Hospital in Monza (Italy) in management and treatment of ectopic impacted lower third molar is exposed through the presentation of three cases of ectopic third molar. Two out of three patients, aware of the risks related to the surgical procedure, refused the treatment proposed. One patient underwent surgical avulsion of the wisdom tooth through extra-oral transcervical approach. No early or late complications have been observed. Extra-oral surgical approach for ectopic lower third molar should be considered for selected cases. Given the rarity of the clinical condition and the procedure-related risks, accurate preoperative information has to be provided to the patient by physician and the procedure should only be performed by expert and competent surgeons.

Objective: Resolution of clinical signs and symptoms following orbital fractures depends on the accurate restoration of the orbital volume. Computer-Assisted procedures and Patient Specific Implants represent modern solutions, but they require additional resources. A more reproducible option is the use of standard preformed titanium meshes, widely available and cheaper; with their use quality of results is proportional to the accuracy with which they are positioned. This work identifies 6 reproducible and constant anatomical landmarks, as an intraoperative guide for the precise positioning of titanium preformed meshes. Methods: 90 patients treated at the Maxillofacial Surgery Department, Niguarda Trauma Center, Milan, for unilateral orbital reconstruction (January 2012 to December 2018), were studied. In all cases reconstruction was performed respecting the 6 proposed anatomical landmarks. The outcomes analyzed are: post-operative CT adherence to the 6 anatomical markers and symmetry achieved respect to controlateral orbit; number/year of re-interventions and duration of surgery; resolution of clinical defects (at least 12-months follow-up); incidence of complications. Results: Satisfactory results were obtained in terms of restoration of orbital size, shape and volume. Clinical defects early recovered with a low incidence of complications and re-interventions. Operating times and radiological accuracy have shown a progressive improvement during years of application of this technique. Conclusions: The proposed "6 anatomical landmarks" is an easy free-hand technique that allows everyone to obtain high levels of reconstructive accuracy and it should be a skill of all surgeons who deal with orbital reconstruction in daily clinical activity.

Background: Reconstruction of full thickness mandibular defects with disarticulation due to ORNJ has traditionally been accomplished using vascularized free fibula flaps (FFF). But not all patients are candidates for FFF. A two-staged protocol (SPR) was developed taking into account the challenges of the surgical site and comorbidities of the patient utilizing custom prosthetics. Methods: This study retrospectively analyzed 16 patients (13 males, 3 females) who developed stage III ORNJ subsequent to radiation and molar extraction (FFF n=4, SPR n=12). Postoperative surgical complications, maximal incisal opening (MIO), Pain Visual Analog Scale (VAS) at the different end points for the SPR and FFF group were analyzed. Results: All patients demonstrated decrease in pain and increased mouth opening. Comparing Stage 1 SPR and FFF patients, there was a significant difference in pain, but not in function (1.89 ± 1.05 vs 0.25 ± 0.5, p<0.01 and 28.44 ± 8.10 vs 24.75 ± 1.26 p>0.20). After completion of the second stage surgery, there were significant differences in function, but not in pain in comparison to FFF patients (24.75 ± 1.26 vs 36.5 ± 8.37, p<0.026 and 0.25 ± 0.5 vs 0.17 ± 0.41, p>0.779). Conclusion: Reconstruction of the temporomandibular joint with a custom prosthesis contributes to the significant improvement in function in the stage 1 SPR and in pain in stage 2 SPR versus the FFF.

Purpose: The aim of this multicentric study was to retrospectively evaluate the surgical outcome of atrophic mandible fractures treated with open reduction and rigid fixation (ORIF), using load-bearing plates. Materials and methods: 55 patients from three trauma centers were retrieved for the study. Inclusion criteria were: edentulous patients with mandibular body fractures; mandibular body thickness <20 mm. Collected data included: cause of fracture; degree of atrophy (according to Luhr's classification); characteristics of the fracture; adequacy of reduction; postoperative complications. All patients were treated with ORIF, using 2.0 mm, large-profile, locking bone plates and 2.4 mm locking bone plates. No bone graft was used in any case. Results: 12 patients were classified as class I atrophy, 18 patients as class II, and 25 patients as class III. Mean mandibular height at the site of fracture was 12.8 mm (ranging from 5.4 mm to 20 mm). 22 were unilateral fractures and 23 were bilateral. Mild displacement was observed in 11 fractures, moderate in 34, severe in 16, and comminution was present in seven fractures. Adequacy of reduction was judged good in 62 fractures and poor in six fractures. Transient weakness of the marginal branch of the facial nerve was recorded in 11 patients and permanent weakness in two patients. All patients achieved a complete fracture healing. Conclusion: External open reduction and rigid fixation (ORIF) with locking, load-bearing plates is a reliable and predictable treatment for atrophic edentulous mandible fracture. Immediate bone grafting should not be considered mandatory unless there is consistent bone loss

Study Design: Retrospective study. Objective: Following SARS-CoV-2 pandemic break-out a lockdown period for the population and a reorganization of the Health System were needed. Hub-function Centers for time-dependent diseases were identified and Niguarda Hospital (Milan) was selected as main Regional Trauma Center. The purpose of our study is to report the experience of Niguarda Maxillofacial Trauma Team during this period, pointing out epidemiological changes in the presentation of trauma in comparison to the previous 3 years. Methods: Two hundred and sixteen patients were admitted to the Emergency Department from 8th March 2020 to 8th May 2020. One hundred and eighty-one had a diagnosis of Major Trauma and 36 had also facial fractures; 35 patients had isolated facial fractures. Data were compared to the activity during the same period in 2017-2019 and statistical analysis was carried out concerning demographic and clinical characteristics, trauma dynamics and positivity to COVID-19. Results: Cumulative curves of patients admitted because of Major Trauma describe a superimposable linear trend in years 2017-2019, while 2020 shows an increase from April 16th. Average age and number of more severe patients were higher than previous years. Epidemiological changes concerned road accidents, accidents involving pedestrians and cyclists, interpersonal violence, suicide attempts and domestic accidents. The incidence of facial fractures was confirmed through years and, according to its measured severity, 75% of patients required management. COVID-19 positivity without systemic symptoms didn’t influence the type of treatment. Conclusion: The COVID-19 lockdown offers a unique opportunity to study the reversal epidemiological effects on trauma.

Maxillofacial involvement in patients with multiple trauma injuries is usually frequent and noticeable, but it is mainly dangerous for ATLS priorities, meaning that it can compromise airway protection (A) and circulation (C) and it can often be associated with brain and cervical spine injuries. Facial hemorrhages are rarely one of the main causes of hemodynamic instability, but their early detection and prompt local control must be supported by each emergency surgeon. In very few, selected and complex cases, when local measures fail, endovascular treatment is today the best option available to achieve definitive control of refractory bleeding. Once the lifesaving priorities are successfully managed, clinicians have to preserve patients’ eyesight as well as limbs; timely clinical diagnosis and appropriate treatment work-up are essential to preserve visual function. On the other hand, we have a few, easy, damage control surgical procedures to save time, thus managing visual-threatening injuries, for instance, anterior orbitotomy is more effective, having a better aesthetic outcome. Being more confident with facial trauma emergency issues allows clinicians to be better able to deal with the comprehensive care of acutely injured patients.

Comprehensive facial injury (CFI) score is a powerful and extremely simple scale used to grade the clinical severity of all facial injuries, and is expressed in terms of the overall surgical time needed for definitive treatment. Its statistical validation was previously reported in 2019. The aim of this study was to investigate further the link with duration of surgery, applying the score to a larger sample of patients, and to evaluate the relationship between CFI score and other extremely relevant dependent variables: length of stay (LOS) in high care units (HCU) and in intensive care units (ICU). 1406 patients with diagnosis of at least one facial bone fracture, and treated by the same team in two highly specialized trauma centers, were studied. For each patient a specific CFI score is assigned and overall surgical time, length of stay, and presence of associated injuries were recorded. Data were divided into six clusters according to CFI score: (1) 0–5, (2) 6–10, (3) 11–15, (4) 16–20, (5) 21–25, and (6) >25. Regressions between CFI clusters and duration of surgery (minutes), LOS in ICU (days), and in HCU (days) were established. In addition, the presence of associated head and/or somatovisceral injuries was analyzed and related to CFI score. Statistical analysis confirmed linear regression existing between each CFI cluster and overall surgical time (p < 0.00001), with improved significance of the results using median values of surgical duration for each cluster (p = 0.0001). It also demonstrated the existence of linear regression between all CFI clusters and LOS in HCU (p = 0.0001) and between CFI clusters 3–6 and median values of LOS in ICU (p = 0.0001). Finally, associated injuries were observed to be more frequent in high CFI score clusters, occurring in around 90% of patients with a CFI score >25 (p < 0.00001). Association of head and facial injuries play a major role in high LOS in ICU values, whereas coexistence of facial, head and somatoviscera

At the time of writing there is no measuring scale for the severity of facial trauma that can effectively summarize its clinical relevance, and can therefore be proposed as a definitive tool in trauma center decision making. This paper introduces a new, simple, comprehensive, and reproducible score for facial trauma, in which its severity is expressed in relation to the surgical duration necessary for definitive treatment. This parameter is identified as the most significant in expressing the commitment of care required. Statistical validation of this comprehensive facial injury (CFI) score involved a sample of 1050 patients, treated by the same team in two highly specialized trauma centers. It demonstrated a linear regression between CFI score and surgical duration, and a high degree of accuracy in forecasting overall surgical time for each type of facial injury. The descriptive capacity of CFI score, and its extremely simple use, make it a perfect tool for widespread application and for facilitating communication inside trauma centers. It also allows the classification of homogeneous groups of patients — a prerequisite for benchmarking and effective analysis of results. The CFI model is definitively proposed for the classification of facial injuries, and therefore for the integration of maxillofacial skills, within the trauma team.

Orbital reconstruction in cases of trauma is usually performed using the unaffected side orbital volume as a reference, but this measurement does not fully consider the anatomical characteristics of orbital surfaces. We propose a novel procedure based on the registration of 3D orbital segmented surfaces. Reconstructed orbits from 20 patients and healthy orbits from 13 control subjects were segmented from the post-operative CT-scans. The 3D orbital model from the unaffected orbit was “mirrored” according to the sagittal plane and superimposed onto the reconstructed one, with calculation of volumes, asymmetry index and point-to-point RMS (root mean square) distances. Inter- and intra-observer errors were tested through Bland–Altman plot. Differences in volume, asymmetry index and RMS value between the control group and the treated patients were assessed through two-way ANOVA and Student's t-test (p < 0.05). According to Bland–Altman test, intra- and inter-operator repeatability was respectively 87% and 89%. No significant differences in volume or asymmetry index between the control group and the treated patients were observed (p > 0.05), but the RMS value was significantly larger in the latter ones (on average, 0.90 ± 0.26 mm vs. 0.67 ± 0.17 mm, p < 0.05). Results show that the reconstructed orbits present a morphologically different surface from the unaffected ones.

Purpose: Autogenous bone represents the best material in pediatric reconstructive cranioplasty because of its compatibility with growth; however, its availability is limited. Alternative use of alloplastic materials would have the advantage of unlimited amount, but shows an increased risk of complications and incompatibility with growth. Fresh frozen banked cadaveric bones could be ideal for the reconstruction of large cranial defects in growing patients, because it offers unlimited amount of structural grafts with biomechanics properties quite similar to the autologous bones. Results: The authors report 2 cases of growing patients (13 months female and 9 years old male) undergoing the reconstruction of large (about 70 cm2 and 50 cm2 respectively) cranial vault defects, by using structural homologous banked bone grafts. Analytic main reconstruction materials risks/benefits evaluation, literature review of few previously reported pediatric cranioplasty with homologous bone, and both clinical cases satisfactory radiologic long-term results (beyond 4 years of F.U.) are reported. Conclusion: Structural homologous banked bone grafts appear as a valid solution for pediatric canioplasty reconstruction of wide defects, entailing the advantages of available without limitations and compatibility with future growth. The risk of transmissible infections seems minimal and is totally counterbalanced by the stability of long-term results.

The care and the management of the healing of difficult wounds at the level of the skull-facial face many problems related to patient compliance and the need to perform multiple dressings, with long periods of healing and, occasionally, a very long hospitalisation period. The introduction and evolution of negative pressure wound therapy (NPWT) in the treatment of difficult wounds has resulted in better healing, with a drastic reduction in terms of time and biological costs to the patient and cost to the health care system. The main aim of this study is to describe and discuss, using out our experience, the usefulness of NPWT in the cranial-facial-cervical region. We studied 16 patients with complex wounds of the cranial-facial-cervical region treated with NPWT. We divided clinical cases in four groups: cervicofacial infectious disease, healing complications in oncological-reconstructive surgery, healing complications of injury with exposure of bone and/or internal fixations and healing complications in traumatic injury with loss of substance. We evaluated complete or incomplete wound healing; application time, related also to hospitalisation time; days of intensive care unit (ICU) stay; management of the upper airways; timing of medication renewal; and patient comfort and compliance (on a scale of 1-5). Depression values were always between -75 and -125 mmHg in a continuous aspiration pattern. For every patient, we used the ActiVAC Therapy Unit, derived from the vacuum-assisted closure system (Kinetic Concepts Inc., San Antonio, TX). Medication renewals were performed every 48-72 hours. The NPWT application time ranged from 4 to 22 days (mean of 11·57day). Therapy was effective to gain a complete restitutio ad integrum in every patient included in the group of cervicofacial infectious disease. Therapy has, however, been well tolerated in our series; this is probably due to the decreased number of applications, the ease of use and the comfort of the system relative

Introduction. Craniometaphyseal dysplasia is a rare hereditary bone disease presenting metaphyseal widening of the tubular bones, sclerosis of craniofacial bones and bony overgrowth of the facial and skull bones. Craniometaphyseal dysplasia occurs in an autosomal dominant (AD) and an autosomal recessive (AR) form.Case report. We present a 32-year-old patient arrived at our unit in May 2009. His main discomfort was a major limitation of the mouth opening, in the context of a craniofacial deformity. Relying on patient's medical history and the performed diagnostic tests, the diagnosis of craniometaphyseal dysplasia was made.Conclusion. After careful evaluation of the clinical case, in accordance with the requirements of the patient, we opted for a surgical treatment aimed at correction of functional limitation of temporomandibular joint and aesthetic improvement of the facial bones. The stability of the clinical results led us to suggest and to undertake the surgical path, also due to the lack of safe and consolidated nonsurgical treatments for the specific case.

Central giant cell granuloma (CGCG) is a relatively rare intraosseous lesion, described bytheWorldHealthOrganizationasalocalizedproliferationconsistingoffibroustissue with hemorrhage deposits, the presence of osteoclast-like cells, and reactive bone formation. In this article, the authors present their experience in managing a wide, aggressiveCGCGofthewholetooth-bearingmandibleina9-year-oldpediatricpatient. The extension of the lesion and the age of the patient have presented a double challenge concerning treatment and outcome. If fact the main objective remains a correct therapeutic treatment, focused on healing the patient and avoiding recurrences,theclinicianmustbecarefulinpreventinganexcessivemorbidity.Theauthors decided to treat the young patient with intralesional corticosteroid therapy, reserving surgery in case of non-response or for subsequent refinements. In this article is presented the authors’ conservative treatment protocol with intralesional corticosteroid injection and their results are compared with literature’s data.

Purpose To determine the dental implant and prostheses success rate in a cohort of patients who underwent a vascularized fibula-free flap (FFF) for maxillary or mandibular reconstruction. Methods The investigators implemented a retrospective cohort study composed of patients who had undergone primary or secondary FFF reconstruction jaw surgery plus placement of 2–6 implants in the reconstructed arch, which were restored with an implant-supported prosthesis. The sample was composed of all patients who underwent FFF surgery between 1998 and 2012 and had either simultaneous or secondary dental implant placement. A total of 28 patients met inclusion criteria. Of these, 22 patients participated in the retrospective review. Patients were examined by an independent observer between January-December 2015. In addition, all patients completed a questionnaire to access satisfaction with the implant-supported prosthesis. Results The patient cohort consisted of 12 males and 10 females, age 12–70 years. A total of 100 implants were placed, 92 implants in fibular bone and 8 implants in native bone. In the maxilla, 35 implants were placed into fibular bone and 4 into native bone (11 in irradiated patients and 28 in non-irradiated patients). In the mandible, 57 implants were placed into fibular bone and 4 into native bone (15 in irradiated patients and 46 in non-irradiated patients). The mean follow-up after implant loading was 7.8 years (range 1.3–17.5 years). The implant survival rate was 98% (95% CI: 92.2%–99.5%). No statistically significant difference was found in implant success between maxillary and mandibular implants, or between radiated and non-radiated bone. The prostheses success rate, determined by clinical exam and patient satisfaction, was 100%. Conclusion The results of this study suggest that implant survival is high and implant-supported prostheses are a reliable rehabilitation option in patients whose jaws have been reconstruction with a FFF.

Osteoblastoma is a benign tumor of bone, representing less than 1% of bone tumors. Craniomaxillofacial localizations account for up to 15% of the total and frequently involve the posterior mandible. Endo-orbital localization is very rare, with most occurring in young patients. Very few of these tumors become malignant. Orbital localization requires radical removal of the tumor followed by careful surgical reconstruction of the orbit to avoid subsequent aesthetic or functional problems. Here, we present a clinical case of this condition and describe a surgical protocol that uses and integrates state-of-the art technologies to achieve orbital reconstruction

Objective: This paper analyzes a series of ultrasound (US)-guided orbital fine needle aspirations (FNAs) which provide diagnostic information that cytopathologists approaching orbital lesions for the first time can find useful and underlines the importance of teamwork. Study Design: The investigators retrospectively obtained data from 24 consecutive orbital FNAs. For all patients, a complete clinicoradiological database was created. FNAs were performed under US guidance with 25-gauge needles and an aspiration biopsy syringe gun, and sent to the Department of Pathology for examination and data management. Results: The mean age of the patients was 54 years. Imaging studies included US, magnetic resonance imaging and computed tomography scans; 9 lesions involved the right orbit and 15 the left orbit. The mean lesion size was 23.6 ± 7.2 mm. After microscopic examination, 7 smears were labeled as 'nondiagnostic', while in 17 cases a definitive diagnosis was proposed, which always proved to be correct (70.8%, specificity = 100%). Conclusions: The investigators believe that FNA biopsy of orbital masses is a necessary step; its weaknesses lie in the particularly delicate site of sampling and the extreme heterogeneity of lesions. Nevertheless, when orbital FNA is performed within a well-coordinated multidisciplinary team, it is a powerful tool that can be used to define the most appropriate management of these patients.

Purpose To analyze the clinical, histologic, radiologic, therapeutic, and prognostic aspects of 6 cases of an uncommon head and neck malignancy and compare these results with data in the literature. Materials and Methods The medical histories of all patients treated in the Maxillofacial Surgery Unit in San Gerardo Hospital (Monza, Italy) for primitive intraosseous squamous cell carcinoma (PIOSCC) of the jaw were reviewed. All patients were considered suitable for inclusion in the study, specifically those whose oral mucosa had not been compromised and who did not have distant metastases. Results Six patients were included (4 male, 2 female). The odontogenic origin was histologically shown in only 2 patients. The male-to-female ratio was 2:1, and the malignancy occurred in the posterior mandible in 50% of cases. The most common symptoms were swelling and pain, but no sensory disturbances were observed. Radiologic findings indicated considerable variation in presentation, including small cystic lesions, which might complicate a pathologic diagnosis. All patients in the study were treated with surgery, and 2 patients received adjuvant radiotherapy. Cervical node metastases were present in 33% of patients. All patients are currently alive and free of disease. Conclusion PIOSCC is a rare malignancy of the head and neck. Diagnosis can be difficult during the early stages of disease owing to a lack of clinical symptoms or radiologic presentation. Treatment is surgical and, like every other cancer, must be adequate to cure the cancer.

Synovial Chondromatosis (SC) is a rare, benign non neoplastic arthopathy characterized by the metaplastic development of cartilaginous nodules within the synovial membrane. In only 3% of all cases does it affect the temporomandibular joint (TMJ) and cases that arise from the lower compartment are rarely found in literature. The aim of this paper is to report a new case of SC of the inferior TMJ compartment with the description of the clinical, therapeutic and histopathological findings

Acute posttraumatic enophthalmos is a well-known symptom occurring in orbital blowout fractures. Its late onset in the absence of radiologic evidence of displaced fractures is rare and traditionally attributed to ischemic liponecrosis or fibrotic scarring of endo-orbital soft tissues. In this article, we describe a case of facial trauma, diagnosed and treated at the Maxillo-Facial Surgical Department of Hospital Ca' Granda Niguarda of Milan, in which delayed monolateral enophthalmos is associated with CT evidence of remodeling of orbital walls attributed to atelectasis of the maxillary sinus, as occurs spontaneously in patients suffering from silent sinus syndrome (SSS). Despite that classic criteria exclude traumatic etiology of SSS, recent literature suggests the possibility to include it. Our case is the first reported in literature supported by complete clinical and radiological documentation obtained before and after the condition established itself. The analogy with cases of spontaneous obstacle of aeration allows us to choose "two-step" surgical treatment with endoscopic uncinectomy and antrostomy and a delayed surgical correction of orbital volume to improve aesthetic results. The case described in this article and the review of the literature may focus physicians' attention on evaluating the possible traumatic changes in the physiologic sinus drainage system

Purpose: Correction of post traumatic orbital and zygomatic deformity is a challenge for maxillofacial surgeons. Integration of different technologies, such as software planning, surgical navigation and stereolithographic models, opens new horizons in terms of the surgeons' ability to tailor reconstruction to individual patients. The purpose of this study was to analyze surgical results, in order to verify the suitability, effectiveness and reproducibility of this new protocol. Methods: Eleven patients were included in the study. Inclusion criteria were: unilateral orbital pathology; associated diplopia and enophthalmos or exophthalmos, and zygomatic deformities. Syndromic patients were excluded. Pre-surgical planning was performed with iPlan 3.0 CMF software and we used Vector Vision II (BrainLab, Feldkirchen, Germany) for surgical navigation. We used 1:1 skull stereolithographic models for all the patients. Orbital reconstructions were performed with a titanium orbital mesh. The results refer to: correction of the deformities, exophthalmos, enophthalmos and diplopia; correspondence between reconstruction mesh positioning and preoperative planning mirroring; and the difference between the reconstructed orbital volume and the healthy orbital volume. Results: Correspondence between the post-operative reconstruction mesh position and the presurgical virtual planning has an average margin of error of less than 1.3 mm. In terms of en- and exophthalmos corrections, we have always had an adequate clinical outcome with a significant change in the projection of the eyeball. In all cases treated, there was a complete resolution of diplopia. The calculation of orbital volume highlighted that the volume of the reconstructed orbit, in most cases, was equal to the healthy orbital volume, with a positive or negative variation of less than 1 cm3. Conclusion: The proposed protocol incorporates all the latest technologies to plan the virtual reconstruction surgery in detail. The res

Head and neck squamous cell carcinoma of the (HNSCC) represents approximately 5% of malignant tumours in Italy. HNSCC are commonly treated with surgery or radiotherapy, or a combination of such therapies. The objectives of treatment are maximum cure rate balanced with organ preservation, restoration of form and function, reduction of morbidities and improvement or maintenance of the patient's quality of life. Immediate reconstructive surgery: local, regional or free flaps are now widely advised in the treatment of these patients. Microsurgical transfer requires expertise, is time and resource consuming, and as a whole requires substantial costs. These considerations introduce some concerns about the wide or indiscriminate use of free flap reconstructive surgery. When considering cost-benefit outcomes of such treatment, the main objective is undoubtedly, survival. This data is underreported in the current literature, whereas functional outcomes of free flaps have been largely diffused and accepted. This study collects data from 1178 patients treated with free flap reconstructive surgery following ablation of HNSCC in a group of Italian tertiary hospitals, all members of the Head & Neck Group affiliated with the Italian Society of Microsurgery. According to many authors, free flap surgery for HNSCC seems to be a beneficial option for treatment even in terms of survival.

Necrotizing fasciitis is a rare polymicrobial, infection, characterized by a rapid and destructive spread within the subcutaneous tissue and along the superficial fascial planes, initially not affecting underlying muscles but with a common systemic involvement. Necrotizing fasciitis confined to the cervico-facial region is extremely rare (10% of cases) and is characterized by a high mortality rate due to airway compromise and to involvement of the supra-aortic vessels. The prognosis for survival is based on the severity of the necrotizing fasciitis, on the patient's systemic condition and on the prompt diagnosis and adequate surgical and medical management. We discuss a case of cervico-facial necrotizing fasciitis in a 25-year-old patient beginning with an odontogenic abscess, resistant to antibiotic therapy, rapidly progressing into an important right-sided swelling of the neck with worsening dyspnea and dysphagia. Because of his worsened general condition, the patient was transferred to the operating room for an emergency treatment. Under general anesthesia, the right cervical and left buccal purulent material was drained via right lateral cervicotomy an aggressive debridement of necrotic tissue, a disruption and excision of the all-necrotic fascia and a removal of the right submandibular gland. Thus, a portable mini-VAC device was applied. The early intervention with a specific diagnostic and therapeutic protocol and the wound treatment by means of vacuum assisted closure therapy allowed to obtain a quick healing, preventing the systemic involvement, minimizing morpho-esthetic outcome and limiting the costs of post-operative wound care
