[Lipoma of the infratemporal fossa. Apropos of a case].

Lipomas of the infratemporal fossa are rare. We report a case that underlines the importance of imaging for diagnosis and treatment. We discuss the incidence, pathogenesis and diagnostic problems as well as therapeutic options for lipomas of the infratemporal fossa.

[Augmentation of the maxillary sinus by Le Fort osteotomy in endosseous implantology. A clinical case report].

The authors present a case of sinus floor elevation using Le Fort I osteotomy. They underline that, owing to its peculiarities, this type of intervention is indicated, in their opinion, for sinus floor elevation when both the vertical dimension and possible skeletal discrepancies require modification. They briefly describe the indications, peculiarities and contraindications.

[Concomitant radiochemotherapy in locally advanced ORL cancers: a prospective study of 68 cases].

From January 1988 to July 1992, 68 patients presenting with a locally advanced and unresectable carcinoma of the head and neck region were given 3 to 5 courses of chemotherapy (5-FU 1 g/m2, day 1 to 3, cisplatin 4 mg/m2, day 1 and 2, 15 mg/m2 day 8) combined with simultaneous radiotherapy. Patients were enrolled in two protocols. In the initial one a 70 Gy total dose was delivered in 105 days, and in the latter the same dose was given in only 63 days.

[Ossifying periostitis (Garrè) and chronic sclerosing osteomyelitis. Diagnostic limits and therapeutic management].

Periostitis ossificans and sclerosing osteomyelitis are rare subtypes of non suppurative chronic osteomyelitis in which there is, additionally, a proliferation of periosteum leading to bony deposition secondary to a mild chronic infection making their diagnosis difficult. The authors report two clinical cases and try to release criteria helping to discern them because the prognosis and therapeutic management of these affections are different.

[Maxillo-mandibular fibrous dysplasia in 2 brothers].

The authors report two cases of maxillo-mandibular fibrous dysplasia showing different form and grow up features affecting two brothers without notion inherited transmission of the lesion. By the way, the diagnostic and the therapeutic management are discussed.

[Irreversible bilateral blindness after functional neck dissection. Apropos of a case and a review of the literature].

Postoperative blindness due to ischemic optic neuropathy is a rare and dramatic complication. A review of the literature from 1960 until nowadays reveal several physiopathological mechanisms of the blindness. Through the description of their clinic case of a fourty seven years old man showing definitive postoperative blindness after sustaining surgery for epidermoid carcinoma of the mouth floor, the authors suggest as etiology the conjunction of the following factors: brain venous high pressure, head and neck oedema, hypotension and the vascular state of the patient.

[Hairy leukoplakia: current concepts].

Current data about oral hairy leukoplakia are reported. Clinical manifestations, histological and ultrastructural features and pathogenic mechanisms are firstly described. Then diagnosis are exposed.

Synovial chondromatosis of the temporomandibular joint possibly secondary to trauma. A case report.

A histologically confirmed case of synovial chondromatosis of the temporomandibular joint associated with a glenoid fossa callus is described. The lesion appeared 6 years after trauma to the chin. Conservative surgical treatment without excision of the synovial membrane or meniscus but including arthroplasty of both the eminence and the lateral side of the glenoid fossa was successful.

[Leiomyosarcoma of the larynx. Histological, immunohistochemical and ultrastructural study of a case with review of the literature].

Laryngeal leiomyosarcoma: histological, immunohistochemical and ultrastructural study of one case with review of the literature. Leiomyosarcoma of the larynx have rarely been reported and a review of the literature has yielded only 8 cases. Authors report a case in a 45-year-old patient.

[Magnetic resonance and salivary pathology. Identification of a lipoma of the parotid gland].

Fatty tissue is easily identified by magnetic resonance imaging by the enhanced signal in sequences weighted T1 and a weak signal in those weighted T2. A lipoma of parotid was identified fortuitously during investigation of a cerebral tumor.

[Complications of the dilatation of Stensen's duct: stenosis and lithiasis].

A recent publication noted the apparent lack of serious complications of dilatation of salivary canals, based on a review of 16 cases. This is contested by the report of three cases of dilatation of Stensen's duct complicated by lithiasis and stenosis, with associated canalar pseudo-cysts. Surgical excision was required and allowed study of histopathology of this affection.

[Benign lympho-epithelial lesion (Blel) of the parotid. Godwin's tumor. A case with cystic ectasia and calcinosis].

We report a case of a benign lymphoepithelial lesion of the parotid gland known as Godwin's tumor. This swelling of the parotid gland, appears as a tumor clinically as well as in scintigraphy and echography. The individual features of this tumor are recognized only during the histological examination: massive infiltration of the lobules of the parotid by a proliferative lymphoid tissue with differentiation to germinal centers and atrophy of the glandular acini.

[Idiopathic bilateral salivary megacanals. Apropos 16 cases].

Investigation in 16 patients attending the stomatology outpatients clinic over the last 18 years has enabled definition of a particular radioclinical entity that has been named "idiopathic bilateral salivary megacanal". This generally parotid affection occurs in patients between 50 and 60 years, the onset usually being by an episode of sialodochitis. In addition to these inflammatory attacks there is the persistence of a bilateral "salivary ejaculation" from the ostia of the principal glands, sometimes after manual expression of a mucoid plug.

[Oral and cutaneous lesions in Crohn's disease. A case report].

Cutaneous and buccal manifestations of Crohn's disease are common. They are diagnostically helpful either by their specificity or from a biopsy which whilst access is easy offers less satisfactory results with buccal lesions. Stomatological clinical aspects are varied, most commonly of aphthoid or vesicular stomatitis type (as in the case reported here).

[Godwin's tumor and Gougerot-Sjögren syndrome. Apropos of 2 cases].

Two new cases of pseudo-tumoral parotid benign lymphoepithelial lesion serve as the basis for a review of the clinical aspects of "Godwin tumour". This is a pseudo-tumoral parotid swelling of non-characteristic clinical appearance which has the radiological findings of a systemic type sialogram ("punctate marks" and diffuse parenchymatous spots). Histopathological examination shows lesions affecting the whole gland but predominant in the swollen area, sometimes surrounded by a connective tissue pseudo-capsule.

[Chondromyxoid fibroma of the temporomandibular joint. Apropos of a case report].

A 32-year-old woman presented with a chondromyxoid fibroma of the right temporomandibular joint. The tumor is rarely observed but this case emphasizes the need for complete radiological investigation of this joint in patients with clinical symptoms localized to this region.

[Radiologic anatomy of the bony lacrimal canal. Axial projections].

Radiologic exploration of the bony lacrimal duct is principally indicated in lacrimal disorders secondary to facial injuries. The use of an axial projection enables analysis of possible displacements or obliterations. Its associations with lacrimography is often indispensable.
