Management and treatment of sinonasal inverted papilloma

Aims: The aim of this paper is to describe the surgical experience of 35 patients with Inverted Papilloma (IP) of paranasal sinuses and its recurrence rate after a year of follow-up. Materials: A retrospective chart review was performed on patients presenting with IP of paranasal sinuses. Thirty-five patients comprised the focus of this study. For all patients was performed a pre-surgery TC, and for more 5 patients it was necessary to perform a Magnetic Resonance (MR) with gadolinium. Results: Among 35 patients selected, 18 patients underwent to open surgery, 4 patients had a combined approach with endoscopy and open surgery, while 13 patients were managed only with an endoscopic approach, with a minimum of 1 year of follow-up. Our results highlighted that the global percentage of success 12 months after the treatment was 93% and it not vary according to the tipology of the approach used if a radical excision of the lesion is achieved. More in depth, among 35 cases, only 2 patients were found to have recurrences and were treated with coronal and endoscopic approach. Conclusion: It is fundamental to underline that surgery must be carried on in a radical manner to treat these tend to recur. A complete removal of the lesion and bone peripheral border filing are essential to perform a correct and definitive treatment. Also, endoscopic approach can be taken into account when tumors are localized median to a sagittal plan crossing the orbit median wall and when they did not massively compromised paranasal sinus walls

Aesthetic restoration in maxillo-mandibular malformations: the role of genioplasty

Aim: The aim of this study was to determinate how orthognatic surgery aids to cure many skull and face abnormalities and to help re-establishing the correct occlusive relation thanks to the repositioning of the maxillo-mandibular skeleton basis. Methods: The study included 183 male patients and 338 female patients, with an average age of 23 years. The sample series was divided according to specific pathologies. All patients underwent surgical procedures and the therapeutic strategy was determined based on the anomalies presented. Results: 113 patients had a II class dental skeletal occlusion, 180 patients had a III class dental-skeletal occlusion and 222 patients had skull-facial abnormalities. 5 patients underwent only a genioplasty, 82 patients underwent a genioplasty associated with BSSO, 175 patients underwent a genioplasty associated with Le Fort I osteotomy and the remaining 253 patients underwent a genioplasty associated with BSSO and Le Fort I osteotomy. Conclusion: The experience shows that genioplasty has been successfully introduced in orthognathic surgical therapeutic procedures, for dental-skeleton abnormalities and mandibular asymmetries treatment. In recent years, the evolution of computer systems has allowed an accurate assessment and programming, by means of the three-dimensional display, which are of great help in the course of diagnosis and evaluation of the displacements to be carried out, in order to obtain optimal aesthetic results

Open reduction and internal fixation of extracapsular mandibular condyle fractures: a long-term clinical and radiological follow-up of 25 patients

Background: During the last 2 decades, many studies on the treatment of mandibular condyle fracture have been published. The incidence of mandibular condyle fractures is variable, ranging from 17.5% to 52% of all mandibular fractures. This retrospective study evaluated the long-term clinical and radiological outcomes after surgical treatment of 25 patients with a total of 26 extracapsular condyle fractures. Methods: We used 2 types of surgical approaches, the retromandibular retroparotid or preauricular approach. Three kinds of rigid internal fixation plates were used—single plate, double plate, and trapezoidal plate. The following post-operative clinical parameters were evaluated: dental occlusion, facial nerve functionality, skin scarring, and temporomandibular joint functionality. All patients underwent post-operative orthopanoramic radiography and computed tomography. The patients were also monitored for complications such as Frey’s syndrome, infection, salivary fistula, plate fracture, and permanent paralysis of the facial nerve; the patient’s satisfaction was also recorded. Results: Of the 25 patients, 80% showed occlusion recovery, 88% had no facial nerve injury, and 88% presented good surgical skin scarring. The patients showed early complete recovery of temporomandibular joint functionality and 72% of them were found to be asymptomatic. The postoperative radiographs of all patients indicated good recovery of the anatomical condylar region, and 80% of them had no postoperative complications. The average degree of patient satisfaction was 8.32 out of 10. Our results confirm that the technique of open reduction and internal fixation in association with postoperative functional rehabilitation therapy should be considered for treating patients with extracapsular condylar fractures. Conclusion: The topic of condylar injury has generated more discussion and controversy than any other topic in the field of maxillofacial trauma. We confirm that open reduction and internal fixation is the treatment of choice for patients with neck and sub-condylar mandibular fractures

Staging of osteonecrosis of the jaw requires computed tomography for accurate definition of the extent of bony disease

Management of osteonecrosis of the jaw associated with antiresorptive agents is challenging, and outcomes are unpredictable. The severity of disease is the main guide to management, and can help to predict prognosis. Most available staging systems for osteonecrosis, including the widely-used American Association of Oral and Maxillofacial Surgeons (AAOMS) system, classify severity on the basis of clinical and radiographic findings. However, clinical inspection and radiography are limited in their ability to identify the extent of necrotic bone disease compared with computed tomography (CT). We have organised a large multicentre retrospective study (known as MISSION) to investigate the agreement between the AAOMS staging system and the extent of osteonecrosis of the jaw (focal compared with diffuse involvement of bone) as detected on CT. We studied 799 patients with detailed clinical phenotyping who had CT images taken. Features of diffuse bone disease were identified on CT within all AAOMS stages (20%, 8%, 48%, and 24% of patients in stages 0, 1, 2, and 3, respectively). Of the patients classified as stage 0, 110/192 (57%) had diffuse disease on CT, and about 1 in 3 with CT evidence of diffuse bone disease was misclassified by the AAOMS system as having stages 0 and 1 osteonecrosis. In addition, more than a third of patients with AAOMS stage 2 (142/405, 35%) had focal bone disease on CT. We conclude that the AAOMS staging system does not correctly identify the extent of bony disease in patients with osteonecrosis of the jaw

Etiology and incidence of zygomatic fracture: a retrospective study related to a series of 642 patients

BACKGROUND AND OBJECTIVES: The aim of this paper is to investigate epidemiological data (age, gender), sites, etiology and surgical approach of zygomatic fracture. MATERIALS AND METHODS: A 9 years retrospective clinical and epidemiologic study evaluated 642 patients treated for zygomatic fracture. There were 569 men and 77 women. The age range was 2 to 86 years with 205 (31.9%) in the 21 to 30 years age group. A number of parameters, including age, gender, cause of injury, site of injury, treatment modalities were evaluated. RESULTS: There were 552 (86%) zygoma fractures and 90 (14%) zygomatic arch fractures. The left zygoma was involved in 309 cases (56%); the right zygoma was involved in 243 cases (44%). Concerning the zygomatic arch, the left side was involved in 43 cases (48%) and the right side in 47 cases (52%). 7% of the patients were younger than 9 years old, about 70% between 10 and 39 years, and 18% between 40 and 59 years, while 4% were older than 60 years. Causes of zygoma fracture were traffic accidents in 151 (26%), assault in 117 (20%), accidental falls in 105 (19%), sports injuries in 56 (10%), home injuries in 45 (8%), work accidents in 34 (6%). Causes of zygomatic arch fractures 28 (29.1%) were assaults in 28 (29.1%), traffic accidents in 20 (21.5%), sports injuries in 14 (15.8%), accidental falls in 11 (14%), domestic accidents in 8 (8.8%) and work accidents in 4 (5%). The access to the fronto-zygomatic suture (74.6%) and the maxillary vestibular approaches (66.8%) were the commonest method of reduction of zygomatic fracture. About arch fractures, the Gillies temporal approach was the most used method of reduction (94.4%). CONCLUSIONS: The findings, compared with similar studies reported in the literature, support the view that the highest prevalence is in young male patients and, concerning cause, traffic accidents and assault are the most frequent

Dermoid Cyst: Unusual Localization

Dermoid cysts are embryonic lesions usually observed in the lateral eyebrow region and the midline nose and neck areas. Communication of these lesions with the central nervous system is rare and occurs in the nasal region. There are few clinical reports of temporal dermoid cysts presenting with intracranial extension, and we present a 15-year-old girl with a fronto-orbital dermoid cyst with intracranial extension and bone erosion. Her presenting symptom was a lacrimation reduction of the left eye. Excision of the cyst was done using a coronal approach because of its extension and localization

Pigmented villonodular synovitis of the temporomandibular joint

Pigmented villonodular synovitis (PVNS) is a relatively rare disease, affecting the synovial-lined joints. PVNS was first fully described by Jaff in 1941, who considered it to be a benign inflammatory state of the synovium of an uncertain etiology Reports of this disease in the temporomanclibular joint (TMJ) are extremely rare. The authors report a case of a 38-year-old woman affected by pigmented villonodular synovitis of the TMJ. Clinical examination revealed the presence of a preauricular mass in the left side; a computed tomography scan showed a 3.0 x 2.0 cm preauricular mass in close continuity to the TMJ capsule. The purpose of this report is to describe the clinicopathological features of a case involving the TMJ. The previously reported cases in the literature are also reviewed

Variations of the gonial angle in vertical surgical reduction of the maxillary-mandibular complex

From an esthetic point of view, the mandibular or gonial angle plays an important role in ensuring a harmonious facial profile. The purpose of this study was to analyze the values of the mandibular angle in relation to variations of the vertical and sagittal positions of the jaw. The study was carried out on a sample of 42 patients who underwent surgery for maxillary-mandibular repositioning, advancing or raising the jaw, after a Le Fort I osteotomy and bilateral sagittal osteotomy of the jaw according to the technique described by Obwegeser-Dal Pont. In all patients, the maxillary bone was raised with a discrepancy of at least 3 mm between the anterior and posterior portions (favoring the latter) as a result of (clockwise) rotation of the bispinal plane. The data, obtained by means of cephalometric analysis according to the method of Ricketts, showed how changes in the gonial angle differed between patients who require correction of an open-bite and those who do not. In particular, in patients without an open-bite, advancement of the maxilla limited the opening of the angle. Similarly, in patients with an open-bite, the tendency to form an open gonial angle can usually be corrected by the association of advancement of the maxilla whenever possible

Orbital floor restoration

Orbital blow-out fractures reconstruction aims to restore the continuity of the orbital floor, to provide support of orbital contents and prevent soft tissues' fibrosis. Different materials have been tested over the years to reach this purpose. Traditionally, autogenous grafts have been used as the material of choice; in recent years alloplastic materials have gained popularity because of their availability and ease of use. The purpose of this study was to review materials used in orbital floor reconstructive surgery at the Department of Maxillo-Facial Surgery of University of Rome '' La Sapienza '', with emphasis on their biocompatibility, their shaping features, and mechanical properties. This report presents the results obtained by the application of these products on 379 patients who underwent surgical treatment for blow-out fractures from 1995 to 2003: the diagnosis of fracture of the orbital floor was based on clinical symptoms and CT axial scanning through coronal reconstruction. Followup period spanned from 1 to 8 years
