[Arthrotic ankylosis of the temporomandibular joint]. / Ankylose de l'articulation temporo-mandibulaire post-arthrosique.

Ankylosis of the temporomandibular joint (TMJ) is a joint stiffness with an oral aperture of less than 30 mm measured between the incisors, occurring because of a bony, fibrous or fibro-osseous fusion. Arthrosis is a rare cause of the ankylosis of the temporomandibular joint. We report a case of ankylosis of the TMJ due to osteoarthrosis, in order to highlight the diagnostic and therapeutic features of this quite uncommon disease.

[Nodular fasciitis of the infratemporal fossa: about a case]. / Fasciite nodulaire de la fosse infra-temporale: à propos d'un cas.

Nodular fasciitis is a benign lesion characterized by a rapidly growing proliferation of myofibroblastic cells which develop at the expense of a muscular fascia inside the subcutaneous tissue. It is often confused with sarcoma due to its rapid growth and its cellular and mitotic richness. Hence, the importance of accurate diagnosis to avoid unnecessary and often mutilating surgeries. This study presents a case of nodular fasciitis arising in an uncommon site, the infratemporal fossa.

Two rare schwannomas of head and neck.

Twenty-five to 45 percent of all schwannomas occur in the head and neck. Most of them arise along the vestibular portion of the eighth cranial nerve (acoustic neurinoma). They rarely originate from the peripheral facial nerve or other nerves within the parotid gland. Less than 4% of schwannomas involve the nasal cavity and paranasal sinuses. They arise from the branches of the trigeminal nerve and autonomic nervous system.We report two cases of schwannomas arisng from intraparotid facial nerve and nasal cavity. The first case diagnosed in a 62-year-old-man presented with 2-year-history of painless mass of the parotid gland. The lesion was found to be cystic through the pre operative examinations and investigations. The histology of the specimen retained an intraparotid cystic schwannoma. The second case concerned a 75-year-old-man presented with episodes of nasal obstruction, rhinorrhea, anosmia and headache. Histological study of the specimen showed fusiform cells with strongly and diffusely immunostaining for S100 protein suggesting a schwannoma.

Congenital infiltrating lipomatosis of the face: report of three cases and review of the literature.

OBJECTIVES: Three new cases of hemifacial hypertrophy caused by congenital infiltrating lipomatosis of the face are reported. The literature on infiltrating lipomatosis of the face is reviewed with an emphasis on accompanying anomalies and treatment strategies. REPORT OF CASES: In this study, the clinical features, radiographic findings, histopathology, and postoperative results were analyzed in three patients with facial infiltrating lipomatosis. The condition was diagnosed in infancy (one male subject, two female subjects) and characterized by enlargement of the cheek. Most patients had early eruption of ipsilateral deciduous and permanent teeth. Computed tomography and magnetic resonance imaging showed an infiltrated soft-tissue mass of fatty density and skeletal overgrowth. Multiple resections were performed on two patients. DISCUSSION: Described first by Slavin and colleagues in 1989, Facial infiltrating lipomatosis is a rare congenital disorder in which mature lipocytes invade adjacent tissue. The phenotypic features include soft-tissue and skeletal hypertrophy, premature dental eruption, and regional macrodontia. Due to its diffuse infiltration and involvement of important facial structures, complete surgical excision is often impossible. The aetiology, natural history, optimal management, and relationship to other disorders of fatty overgrowth are unclear. Because surgical removal of the mass is usually unsuccessful, specific management of this condition will require insight into its pathogenesis.
