[The surgical management of obstructive sleep apnea syndromes. Preliminary phase I results (the Stanford technic) in a series of 26 patients].

Surgical management of obstructive sleep apnea remains a surgical challenge. Multidisciplinary collaboration is a fundamental element. We report the principles of management as proposed to the patient and preliminary results obtained in a series of 26 patients treated in the phase I of the Stanford protocol. Cure rate after this phase was 50%. Different research projects in this area are discussed.

[Supernumerary molars. Apropos of 10 cases].

We report 10 cases of supernumerary teeth. Their incidence among our patients is 1.01 per cent. A review of the literature is exposed concerning their etiology and their treatment planning.

[Complications of silastic implants used in orbital repair].

Several questions concerning the material to be used for surgical repair of fractures of the orbit are still under debate. Surgeons may choose between autologous or heterologous grafts or different biomaterials. We conducted a retrospective analysis of 137 patients treated in our unit for fractures of the floor of the orbit over the last 20 years who received a silastic implant. After 20 years, the rate of complications requiring removal of the implant was 13.8%. Complications observed were dacryocystitis, implant migration to the skin and the maxillary sinus, skin fistula, persistent diplopia, communication between the orbit and the sinus, periorbit cellulitis.

[Venous hemangioma of the temporal muscle. Review of the literature: apropos of a case].

A 41-year-old woman progressively developed a painful tumefaction in the left temporal fossa. The scan showed a isodense intramuscular structure weakly enhanced by contrast medium. Surgical exeresis was performed via the coronal access. Histology of the surgical specimen reported the diagnosis of venous muscular haemangioma. The diagnosis and management of these rare tumours is discussed.

[Silastic implants and reconstruction of the orbital floor: review of twenty year's experience].

Fractures of the orbital floor still raise unresolved therapeutic problems concerning the operative indication or the type of material to be used during repair. For this purpose, surgeons have the choice between heterologous or autologous grafts, implants and numerous biomaterials. The authors conducted a retrospective study with a follow-up of 20 years of 137 patients treated in the department for a fracture of the orbital floor using a Silastic implant. The reoperation rate to remove the implant was 13.8%. Various complications were observed: dacryocystitis, migration of the implant to the skin and maxillary sinus, cutaneous fistula, persistent diplopia, orbito-sinus communication, periorbital cellulitis. In view of these complications, it appears preferable to modify the therapeutic approach and propose autotransplantation of the concha for defects less than 1.5 cm2 and autologous parietal bone graft for larger defects.

[Craniofacial architecture and temporomandibular joint pain-dysfunction syndrome. The possibility of orthodontic treatment].

The authors report the results of cephalographic studies in 65 cases of temporo-mandibular algo-dysfunctional syndromes. Cephalometric analysis according to the method described by Delaire allows specific cranio-facial morphotypic criteria to be defined. These results warrant presentation since they are frequently encountered but do not constitute a pathognomonic presentation. Statistical analysis of dento-maxillo-facial orthopedic abnormalities underlines their very frequent occurrence. The indications for maxillo-facial orthopedic surgery should therefore be widened.

[Serious cervicofacial infections of dental origin].

A review of 14 cases of serious cervico-facial infections of dental origin. The authors report a current mortality rate for acute diffuse cellulitis, of close to 50%, regardless of the publication. They stress the therapeutic errors which are the most frequent causes for delay in effective therapy which should obligatorily include: methodic surgical drainage, suppression of dental causes and appropriate antibiotic therapy.

[The Temporomandibular Joint Diseases Unit of the Villeneuve-Saint-Georges Hospital Center].

A disease as complex as that of temporomandibular joint dysfunction can only be managed by a multidisciplinary team. The authors describe the temporomandibular joint diseases unit of the Centre Hospitalier de Villeneuve-Saint-Georges which consists of Stomatologists, Radiologists, Psychiatrists and Psychologists and a Rehabilitation Medicine doctor specialised in electrodiagnosis. The hospital's Department of Stomatology and Maxillofacial Surgery (Doctor Pierre Scheffer) coordinates this unit which holds committee meetings one a month to evaluate each case. The therapeutic decisions reflect the multiplicity of the aetiologies, none of which are mutually exclusive, which explains the necessity for a multidisciplinary approach.

[Opaque arthrotomography: a routine examination in temporomandibular dysfunction].

Tomographic examination of the temporo-mandibular joint after opacification of the meniscotemporal and meniscocondylian stages is an effective method of exploration of intra-articular lesions of the meniscal dynamic complex. Normal arthrotomographic appearances are described and four evolutory stages of the lesions proposed; by order of increasing seriousness: anterior position of meniscus, reducible anterior luxation, irreducible anterior luxation, meniscal perforation. The value of this examination is important during discussion of selective surgical treatment in painful dysfunctional syndromes of the temporomandibular joint.

[Reducible meniscal luxation of the temporomandibular joint].

Normal and pathologic functioning of the temporomandibular joint are summarized and clinical and arthrographic signs of reducible meniscal luxation described. The latter is distinguished clinically and radiologically from irreducible meniscal luxation and the myofacial syndrome. Etiological features are discussed and therapeutic solutions proposed in relation to three clinical cases reported.

[Anterior open bite: the role of the infra-alveolae in its diagnosis and treatment].

Anterior open-bites may be skeletal, alveolar or mixed. The infra-alveolae is always due to a postural or functional muscular cause and the clinical examination plays an important part in the diagnosis. Delaire's cephalometric analysis can define the type of infra-alveolae. In view of their aetiology, the infra-alveolae require functional re-education, although glossectomy and multiple bands therapy may also be useful.

[Prognosis and procedure in the surgical and orthodontic treatment of maxillomandibular dysmorphism].

The treatment of maxillo-mandibular dysmorphies, which involves both surgery and orthodontics, depends on a precise diagnosis and tactical strategies based on simulations of treatment using teleradiography, telephotography and impressions. These measures are essential in order to obtain a stable, good quality result in terms of occlusion and the dental, pariodontal and skeletal aspects.

[Anomalies of the path of closure].

Authors show some examples of shuting-way abnormalities. They show that only alveolar inclination can, by changing these abnormalities, modify the maxillo-mandibular occlusion.
