[Screening and diagnosis of epidermoid carcinoma of the oral mucosa. What conclusions are possible today concerning the respective roles of cytologic smear and biopsy?].

Oral malignancies are a major problem in France where the consumption of alcoholic drinks is a traditional habit, often associated with heavy smoking. Contrary to other malignancies, at least in France mass screening has never been used to detect oral carcinoma. Preventive steps are very difficult to implement due to different economic reasons but mass screening in patients with records of heavy drinking/smoking, and/or pre-epitheliomatous lesions is an easy method after a short training of doctors in different specialties and cyto-pathologists.

[Prosthetic treatment of mandibular pseudarthrosis using an articulated prosthesis].

Two cases with complete loss of the tooth-bearing portion of the mandible were repaired with a prosthesis. This type of defect can involve the loss of a large number of teeth and aggression to the remaining teeth must be limited as much as possible. A two-part "articulated" prosthesis with two rings appears to be the best adapted system.

[Temporomandibular ankylosis: an analysis of hospital records and a review of the recent literature].

Ankylosis of the temporomandibular joint has severe consequences due to its effect on eating, speaking, buccal hygiene and growth of the lower third of the face in children. Two therapeutic problems must be addressed: functional capacity (joint mobility) and morphological (correction of the facial deformation). The appropriate surgical techniques are still subject to debate.

[Maxillary ameloblastoma. Apropos of a case and review of the literature].

Although ameloblastoma is one of the benign odontogenic tumors, the maxillary localisations often grow more infiltratively and show higher recurrency than the mandibular localisations. The authors report a case of ameloblastoma in maxillary sinus and sketch out the operative methods with a literature review.

[Surgery of the infratemporal fossa. An improved cutaneous access technic].

Unlabelled: Surgery in the infra-temporal area, formerly known as the pterygo-maxillary area, is not often performed and raises several problems including the route of access and indications and contraindications. Many procedures have been proposed by ENT or maxillo-facial surgeons dealing with cancer.

Anatomy: The infratemporal area is a basically pyramidal shaped, very deep region of the face.

Liver resection with normothermic ischaemia exceeding 1 h.

A retrospective study was made of 34 patients who underwent major liver resection with a single period of vascular occlusion exceeding 60 min. The liver remnant was normal in all cases. Vascular occlusion was achieved by continuous portal triad clamping (15 patients), hepatic vascular exclusion (15) or a sequential combination of both procedures (four).

Pancreatico-duodenectomy for cancer and precancer in familial adenomatous polyposis.

Duodenal adenomas occur in most patients with familial adenomatous polyposis and their potential for malignant transformation appears to be high. In case of rapid polyp growth or severe dysplasia, the place of surgical resection is controversial. We report 2 patients with familial adenomatous polyposis who underwent radical pancreatico duodenectomy several years after the treatment of colonic polyposis.

Repeat liver resection for recurrent colorectal metastases.

Sixteen patients underwent 18 repeat liver resections for recurrence of colorectal hepatic metastases that had been previously resected. Only minor liver resection had been undertaken at the first operation; three were palliative. The second operation was major hepatectomy in ten patients, minor resection in five and orthotopic liver transplantation in one.

[The trapezoid face: transversal excess in the maxillary area].

The patient who consults for "big cheeks" usually desires correction for an excess of tissue in the masseter region. First all neoplastic pathologies recognized by their unilateral asymmetry are excluded in order to focus on bilateral phenomena. Three anatomical elements can be responsible either alone or in association for this excess: the parotid gland, the masseter muscle and the angle of the jaw.

[Radiologic pitfalls of mandibular fractures].

Analysis of a large series of patients treated for mandibular fractures showed pitfalls in assessment of radiologic images in six cases. Factors predisposing to these radiologic pitfalls are discussed, multiple radiographic projections being suggested if discordance exists between radiologic and clinical findings, to obtain maximum data from a three dimensional picture of the mandible.

[Cherubism. Apropos of a major case].

Cherubism is a benign, hereditary giant-cell lesion located in the mandible and both maxillaries, which appears during childhood as a painless bilateral swelling, progressing until puberty and then receding spontaneously without normally requiring any treatment. In a previous publication, the authors had presented the case of three young children from the same Algerian sibship, who were eventually all operated when surgery proved to be necessary. The case published in this presentation is that of a young Italian girl presenting with a monstrous form of cherubism.

[Complex reconstruction of the lower lip. Apropos of various cases].

Preservation of buccal cavity relations raises problems when treating extensive defects of lower lip. After a review of anatomical features, several case reports are presented to illustrate the advantages and inconveniences of three interventions for labial reconstruction.

[mandibular reconstruction by free bone flaps with micro-anastomosis. Our current indications].

The frequency with which difficulties were encountered in the reconstruction of the continuity of the mandible led us to attempt to systematize our indications. Although grafts, composite pedicle flaps and prosthetic guides still have their appropriate applications. Local conditions are more and more frequently amenable to free flaps.

[A malignant salivary lymphoepithelial lesion with a poorly differentiated epidermoid carcinoma. Apropos a case].

A case of malignant lymphoepithelial lesion of the submandibular gland is reported in a 71-years-old woman. The carcinoma showed a poorly differentiated pattern and its epidermoid nature was obvious after immunohistochemistry and electron microscopy. The epithelial nests were lying in an abundant lymphoid stroma consisting of small lymphocytes.

[The maxillofacial surgeon faced with the HIV-positive patient: risks and prevention].

Prevention against the transmission of the HIV must be universal today, which means that it applies to all patients. Blood, tissues, the CSF are infected, but nasal secreta, tears and saliva are not contaminated unless they contain blood. The statistical risk of an HIV serological conversion when making an injection is an estimate of 0.

[Apparently primary malignant cervical adenopathy].

Despite a thorough examination it is not always possible to detect the primary cancer responsible for malignant cervical adenopathy. In the vast majority of cases the metastases arise from an epidermoid carcinoma of the upper respiratory or digestive tract. A possible diagnostic, but also therapeutic procedure is exploratory cervicotomy with extemporaneous examination.

[Isolated sub-orbital plexiform neurofibroma].

An unexpected finding on histology in a 73 years old patient was an isolated suborbital plexiform neurofibroma. Since this tumor is specific for von Recklinghausen's disease, the diagnosis was that of a minor form of the disease. The different cephalic manifestations of von Recklinghausen's disease are reviewed.

[Mandibular fractures. Our patient enrollment during the past 2 years].

The method of patient referral; the patient's physical predisposition, the localization and the treatment undertaken for the different mandibular fractures seen by SOS Face over the past two years were analyzed. The 312 mandibular fractures were used to reevaluate the commonly accepted statistics concerning these parameters.
