RESUMEN
INTRODUCTION: Psychological morbidities are major complications following maxillofacial injuries. The aim of this study was to assess self-evaluation of oral and maxillofacial surgeons on posttraumatic psychological care. METHODS: Using a cross-sectional study design, we enrolled a sample of surgeons in 261 oral and maxillofacial surgery (OMFS) departments in the United States, United Kingdom and France. A self-administered e-mail questionnaire was used to evaluate knowledge, attitude and practice of the surgeons regarding psychological problems in maxillofacial injury patients, and their collaboration with psychological personnel. Appropriate descriptive and univariate statistics were computed, and P<0.05 was considered statistically significant. RESULTS: The response rate was 28.1% (112 of 398), but we included only 100 respondents from 107 OMS units. 60% of the surgeons disclosed a moderate or high level of relevant knowledge. Only 28 OMS departments (26.2%) had intra-service psychological staff (commonly in France [P<0.05]), and five surgeons revealed considerable deficits in access to psychological care. Frequent reasons for patient referral to psychological staff were depression, body dysmorphic disorder, posttraumatic stress disorder, suicidal idea, anxiety and behavioural changes. Eighty-eight surgeons linked patient's non-compliance with changes or difficulties in practice, and 58 surgeons experienced it already. CONCLUSIONS: Despite several limitations, the results of this study suggest that oral and maxillofacial surgeons have a great interest and experience in posttraumatic psychological problems. Psychological professionals in charge will improve surgical care quality. Well-designed studies with larger sample size are desirable to confirm our results. Ethical issues of maxillofacial trauma care are also discussed.

Donor site morbidity for free fibula osteofasciocutaneous flaps has rarely been reported in the literature. We report on a case of acute compartment syndrome (ACS) in a 22-year-old male, following fibula flap harvest for mandibular reconstruction and arising after post-ischemic reperfusion damage. Dissection during this patient's surgery was unusually difficult. The skin defect was covered with a loose dressing while waiting for secondary grafting. Intracompartmental pressures measured by the Wick catheter technique confirmed the diagnosis of ACS. ACS is an unexpected complication after fibula flap harvest since the three compartments of the leg are opened during surgery. Only four cases of ACS have been reported in the literature. Analysis of this serious complication might lead to changes in the routine use of the pneumatic tourniquet in some selected cases. New automatic tourniquet systems might also be advantageous in such cases.

BACKGROUND: The treatment of odontogenic keratocyst (OKC) of the jaws remains controversial. The aim of this study was to report the outcome of our conservative treatment protocol for OKC. METHODS: We collected data of all OKC patients treated in the Department of Maxillofacial Surgery, Pitié-Salpêtrière University Hospital from 1995 to 2004. Basal cell naevus syndrome (Gorlin's syndrome) patients were excluded. Recurrence data was analysed in relation to radiographic features, type of microscopic diagnosis, presence of cortical perforation, and site of involvement. RESULTS: One hundred and twenty cysts in 109 patients were examined. OKCs were more frequent in the third and the fourth decades of life (range: 11-79 years, mean: 40 years) and in men (n=71). Most of the lesions were unilocular radiolucencies in the tooth-bearing area and in the posterior part of the mandible. Histologically, 80 lesions showed parakeratosis. Most of the patients underwent uneventful enucleation. Postoperatively, infection occurred in 4 patients, and there was no jaw fracture. Recurrence was found in 28 cysts (26%), of which 7 cysts (6%) had multiple recurrences. There was no significant association between recurrences and radiographic features, histological type, cortical perforation, or site of involvement (P>0.05). Recurrences were common in the first 5 years after the operation. The average follow-up was 86 months since the last operation (range: 18-151 months). CONCLUSIONS: Despite the retrospective nature, no control group and a relatively high recurrence rate, our study suggests that enucleation with the aid of computed tomography and adequate postoperative surveillance is a conservative treatment which yields clinically acceptable results. However, the patients must strictly adhere to close follow-ups because recurrences may have serious consequences. Our algorithm for managing OKCs and cyst-like lesions of the jaws is also presented.

INTRODUCTION: Kimura's disease (KD) is a chronic inflammatory disorder, characterised by tumour-like lesions in the head and neck region, producing salivary gland nodules and lymph node enlargement. Many authors suggest that KD is a reactive immunological disorder; however, its aetiology remains unknown. AIMS: To study immunohistochemical characteristics of head and neck lesions of KD (H&N-KD) and to investigate the possible role of human herpesvirus-8 (HHV-8) and Epstein-Barr virus (EBV) in the development of H&N-KD. PATIENTS AND METHODS: This study enrolled five H&N-KD specimens from three patients treated between 1995 and 2005 at Pitié-Salpêtrière University Hospital, Paris, France. Immunohistochemical studies were performed on formalin-fixed, paraffin-embedded tissue. HHV-8 DNA was determined by polymerase chain reaction (PCR) analysis, whilst EBV sequences were identified by PCR and in situ hybridisation. RESULTS: The immunohistochemical studies revealed CD20+ germinal centres with prominent staining of CD23+ dendritic reticular cells, surrounded by numerous interfollicular CD3+, and CD4+ or CD8+ T-cells. Factor VIII-related antigen, CD31 and CD34 occurred in the thin-walled blood vessels. The reactivity of CD1a, HHV-8 and EBV-associated latent membrane protein 1-EBV (LMP1-EBV) were negative, and in situ hybridisation confirmed the lack of EBV DNA. No patient recalled an external insult or chronic irritation. CONCLUSIONS: The results of this study indicate the reactive nature of H&N-KD (or a subset of H&N-KD), and it is unlikely that HHV-8 and EBV play a role in the pathogenesis of the lesion. However, the patients in this series did not have previous history of trauma or chronic irritation; thus, a neoplastic origin could not be excluded. Further multicentre studies based on more specimens are warranted.

In this review, we examined a 45-year-old Asian man who had been diagnosed with florid osseous dysplasia (FOD) of the mandible and acute perimandibular cellulitis. This presentation occurred after a history of off-and-on swellings of the jaw and multiple treatments received at another hospital. An aggressive resection of the jaw was planned; however, the patient denied the treatment and came to our clinic to seek a second opinion. The patient was successfully treated by conservative surgery and antibiotic treatment with preservation of the jaw integrity and the mandibular neurovascular canal. Intraoperatively, a piece of a calcified mass was removed and submitted for histopathological examination. The specimen showed woven bone and densely sclerotic mass of calcified materials exhibiting reversal lines and inflammatory cell infiltration of the connective tissue. The definitive diagnosis was FOD with a secondary infection. Treatments for FOD were discussed.

Ameloblastic fibroma (AF) is a rare odontogenic tumour of the jaw which usually occurs in the first 2 decades of life. The common clinical manifestation is a slow-growing swelling. We report a case of a 16-year-old male patient presenting with extensive AF of the mandible. He underwent a conservative enucleation. The tumour recurred 2 years after the initial surgery, requiring the second enucleation. The patient has continued to be followed closely and has been disease-free for 4 years. Recent evidence suggests that the recurrent rate of AF is relatively high, and malignant transformation of AF may occur after recurrences or multiple surgeries. A conservative treatment approach with close surveillance is recommended. Anatomical limitations should be taken into account, especially when enucleation of AF in the posterior portion of the jaw is performed. Current surgical pathologic issues of the tumour are also discussed.

OBJECTIVE: The objective of this study was to analyze complications following fibular free flap (FFF) transfer for mandibular reconstruction using our definition of postoperative complications. STUDY DESIGN: Retrospective observational study. PATIENTS AND METHODS: This retrospective study presents our 4-year experiences with FFF for mandibular reconstruction by a single microsurgical team. Data were collected through patient record review and clinical evaluation by 2 independent assessors. We defined complications as any unwanted postoperative outcomes that compromised patient care. Early complication occurred within the first 2 weeks postoperatively; late complications occurred afterward. RESULTS: Of 25 patients included, 13 patients (56%) experienced complications. Early and late complications occurred in 13 and 9 patients, respectively. These included flap loss, malunion, skin-paddle necrosis, orocutaneous fistula, wound dehiscence, hematoma, soft tissue contracture, intraoral hair growth, facial asymmetry, osteoradionecrosis, donor-site morbidity, and medical complications. Revision surgeries were performed in 10 patients, ranging from wound dressing to flap removal. All but 2 flaps survived, yielding an overall success rate of 92%. Most of the patients were alive without disease (92%) at the end of the study. Average follow-up was 47.2 months (range: 26-77). CONCLUSION: Despite the small number of patients, these preliminary data suggest a relatively high frequency of complications following the FFF reconstruction based on our definition. Minor complications are common and should not be neglected because they may lead to devastating consequences. This should also be a part of informed consent for patients. Complications after the FFF transfer await keen evaluation to establish guidelines to improve end results.

During a 13-year period (from 1994 to 2007), in the Oral and Maxillofacial Surgery Department of the Pitié-Salpêtrière Hospital, 116 new cases of adult ameloblastomas, were analyzed for treatment composed against radiographic presentation, size, histological type. Follow-up and recurrence were also analyzed. Treatment was surgical consisting of enucleations (82%), segmental mandibulectomy (8.3%) resections (24.7%) 85% of them underwent reconstruction. The follow-up was documented for 97%. More than two recurrences occurred in 21% of the patients after the first enucleation: 66% with a "follicular" histological diagnosis. Lenthly, a therapeutic algorithm is suggested for adult ameloblastomas that underlines the importance of the conservative enucleation treatment as far as possible.

INTRODUCTION: Despite using aggressive treatment, patients with Ewing's sarcoma (ES) always show a high recurrence and a low survival rate. Ki-67 has been used widely in surgical oncology. PATIENTS AND METHODS: This case report identified the Ki-67 expression in jaw bone ES from 4 adult patients operated upon between 1996 and 2005 in Pitié-Salpêtrière University Hospital, Paris, France. The clinical data of each patient was also reviewed. RESULTS: Ki-67 reactivity was found in 3 cases. Two of 4 patients with 50% and 80% of Ki-67 positive tumour cells had local relapse at 5 years and 8 months after treatments, respectively. Furthermore, the patient with 80% Ki-67 expression exhibited resistance to chemotherapy and died a year after resection. The other 2 cases revealed no evidence of recurrence and metastasis to date. CONCLUSION: Ki-67 expression is likely to be associated with tumour recurrence and poor prognosis in jaw bone ES in adult patients. This marker probably helps surgeons to plan and employ appropriate treatment and/or surveillance for each patient; however, the number of cases in this series is very limited. A large-scale, prospective study is, therefore, required to confirm our suggestion.

Gorham disease (GD) is a rare osteolysis without sex, race, or age predilection, affecting bones in different regions. Based on clinical, histological, and molecular features, diagnosis is difficult and required exclusion of neoplastic, inflammatory, infectious, and endocrinologic disease. Etiology is still unknown. We report the case of a 36-year-old man suffering from severe progressive osteolysis located at the mandible. Histology showed massive osteolysis without malignant cells. Immunohistochemistry revealed thin-walled vessels and lymphatic ducts. These investigations lead to diagnosis of GD. Radical surgical treatment was followed by bisphophonate therapy. Recurrence occurred 4 months after surgery and alphaa-interferon therapy permitted remission. To support this case report, we reviewed the 41 maxillofacial cases published in the literature since 1928. Jaw is the main location; histology mostly shows hemangioma-like proliferation. Immune disorders are usually advanced as a cause although physiopathology is unknown. Therefore, appropriate treatment is controversial. Antiosteoclastic drugs are usually proposed in addition to surgery, but immunomodulating drugs and radiation therapy should also be considered in the treatment.

BACKGROUND: A bicentric, prospective cohort study was performed to assess the outcome of rhinoplasties from the patient's perspective. METHODS: Fifty-eight patients scheduled for rhinoplasty from two different hospitals (public and private) were examined before and after surgery using the Rhinoplasty Outcomes Evaluation, a specific validated assessment scale. For statistical analysis, paired Student's t test and the Mann-Whitney test were applied. Student's t test was used to compare preoperative and postoperative scores. RESULTS: The scores of both the cosmetic and the posttraumatic patients were significantly improved by rhinoplasty (p < 0.0001). There was no significant difference when the authors compared the improvement scores of subgroups ranged by age, sex, primary versus secondary rhinoplasty, time between first consultation and surgery, posttraumatic versus non-posttraumatic patients, and functional versus nonfunctional indications. CONCLUSIONS: Whatever the type of initial demand (posttraumatic, cosmetic, or functional), rhinoplasty significantly increased Rhinoplasty Outcomes Evaluation scores. The study design did not allow the authors to determine subgroups of patients more able to obtain an important improvement score.

Plasmablastic lymphoma is a rare subcategory of non-Hodgkin lymphoma frequently associated with human immunodeficiency virus. It is a large B-cell lymphoma that has a predilection for the oral cavity. Clinically, plasmablastic lymphoma may mislead to a diagnosis of Kaposi's sarcoma. When infected, plasmablastic lymphoma may mimic an odontogenic cellulitis. Epstein-Barr virus and human herpesvirus 8 are very often associated. Awareness of this entity can prevent misdiagnosis with nonlymphoid malignancies, notably Kaposi's sarcoma, because this lesion does not express the conventional B-cell markers. Unfortunately, as for other high-grade lymphomas in patients with acquired immunodeficiency syndrome (AIDS), the prognosis is poor. The case of a heterosexual 42-year-old man referred for a right hemifacial neoplasm is reported.

The loss of mandibular molars can result in a maxillary dentoalveolar extrusion, leading to an insufficient interarch space. In severe cases, this space must be regained before the prosthetic reconstruction of the opposite edentulous area. The posterior maxillary segmental osteotomy (PMSO) is a simple but precision technique to manage this problem; without which one can achieve a good surgical outcome but a poor final occlusion. The purpose of this paper was to present a case of PMSO for mandibular implant placement and to discuss the important steps.

PURPOSE: To describe an endoscopic technique for submandibular sialoadenectomy in humans, as well as the equipment, instrumentation, and pertinent anatomy. MATERIALS AND METHODS: Six submandibular sialoadenectomies were carried out in 5 patients (3 women, 2 men; mean age, 26.6 years; range, 16 to 42 years) via a 15 to 20 mm neck incision for insertion of the endoscopic camera and surgical instruments. RESULTS: All operations were successful without conversion to an open surgery. Operative time was 20 to 120 minutes (mean, 65 minutes). All patients were discharged the day after surgery. There were no postoperative complications (hematoma, nerve injury, infection). All patients experienced a mild degree of edema, which had resolved totally at the 6-month follow-up visit. All patients were satisfied with the outcome and especially the cosmetic result. CONCLUSIONS: Absence of extensive scars, nontraumatic dissection, and magnification of anatomic structures are the most obvious advantages of this innovative technique.
