[Treatment of two cases of periodic sleep apnea by maxillo-facial surgery].

Juvenile temporomandibular bony ankylosis may generate micro- and retroposition of the mandible. Collapse of the upper airway during sleep due to muscle atonia awakens the patient, leading to compensative diurnal hypersomnia. In severe cases, alveolar hypoventilation may result in anoxic seizure, sudden death or development of life threatening cor pulmonale. The corrective surgical procedure for adult is an anterior sagittal osteotomy and in the growing child, costochondral grafting is proposed. Pre and post operative polysomnograms with recording of oxygen saturation are objective measures of good surgical results.

[Basal cell nevus].

The main features of the nevoid basal cell syndrome, also called Gorlin-Goltz-syndrome, are basal cell nevi, jaw cysts, anomalies of the vertebras and ribs, and intracerebral calcifications. The diagnosis is often incidentally made by discovery of bilateral jaw cysts, as it was in the case of our patient and her family. The therapy is the complete enucleation of the cyst. The cavity is filled with homologous cancellous bone graft. Recurrence and little cysts are treated with the solution of Carnoy eliminating remaining microcysts.

[Resection and reconstruction of mandible for treatment of two rare benign tumors].

Odontogenic myxoma and particularly juvenile fibromatosis are rare benign tumors in the maxillo-facial region. The aggressive local and sometimes voluminous development of these tumors may necessitate partial mandibulectomy. Autologous bone graft from the iliac crest is the best material for mandibular reconstruction because of its functional and esthetic results. If osteosynthesis of the graft is achieved by means of internal wiring, several weeks of intermaxillary fixation are required, whereas internal rigid fixation with plate and screws allows the patient to open the mouth more rapidly.

[Sleep obstructive apnea syndrome and temporomandibular ankylosis. Maxillofacial correction for adults and children].

Juvenile temporomandibular bony ankylosis may generate micro- and retroposition of the mandible. Collapse of the upper airway during sleep due to muscle atonia awakens the patient, leading to compensative diurnal hypersomnia. In severe cases, alveolar hypoventilation may result in anoxic seizure, sudden death or development of life threatening cor pulmonale. The corrective surgical procedure for adult is an anterior sagittal osteotomy and in the growing child, costochondral grafting is proposed.

[Difficult intubation in maxillofacial surgery. Tracheotomy or fibroscopy?].

Prior to general anesthesia, some maxillofacial conditions may require tracheostomy or, in recent years, fiberoptic endotracheal intubation. This technic is efficient but delicate and therefore needs a skilled qualified operator. However, fiberoptic endoscope may avoid the inconvenience of tracheostomy. This article presents our method of fiberoptic endotracheal intubation with the specific indications and results.

Deliberate, fixed extra-articular obstruction. Treatment of choice for subluxation and true recurrent dislocation of the temporomandibular joint.

Temporomandibular dislocation and subluxation are two pathological situations both characterized by hypermobility of the condyle. We believe that when luxation is recurrent and when subluxation becomes painful or is accompanied by disc dysfunction, surgical intervention is indicated. We are impressed by Gosserez and Dautrey's (1967) method of augmentation of the tubercle, or extra-articular obstruction, which is a modification of Leclerc and Girard's (1943) original procedure. The advantages of this technique are described and results are based on a series of 38 patients.

[Surgical treatment of pain of meniscal origin].

Meniscal blocking of the TMJ is encountered by first trying to reduce it manually, if necessary under general anesthesia and curarization. Otherwise surgery is indicated. Meniscectomy is not recommended because of the danger of arthrosis. An arthroplasty is performed, the fibrocartilage removed and the condyle remodeled. The fibrocartilage regenerated totally, as could be shown experimentally. This intervention eliminates painful blocking of the joint and clicking during the first half of opening movements.

Long term follow-up of the sagittal splitting technique for correction of mandibular prognathism.

In a study of 67 cases the authors have investigated clinically and radiologically the long term results (5 years and over) of the sagittal split technique (Obwegeser 1955, 1957). Although 95% of the patients are satisfied, 60% have some impairment of sensation in the lower lip. This however goes unnoticed in 40% of these cases. The temporo-mandibular joint does not appear to be affected. 73% of the patients have excellent or good occlusion, while 18% have an unsatisfactory anterior occlusion due to some degree of relapse. The remaining 9% have poor occlusion without sign of relapse. A statistical analysis of the teleradiographs reveals that relapse is due to a rotation of the body of the mandible. Since several changes in technique have meanwhile been adopted, this paper will be followed by an analysis of the more recent cases.

[The role of orthodontic surgery in mouth rehabilitation].

The surgical treatment of malformations of jaws offers actually many possibilities. Basic principles of this specialized surgery are exposed: an exact diagnosis, the problem of incisions which must be hidden, age upon operation and association with other specialties. In the oral rehabilitation, this type of surgery permits total correction of complex malformations, which are impossible to treat completely by other methods.

[Osteochondroma of the mandibular condyle. Case report (author's transl)].

A rare case of osteocartilaginous exostosis, also called osteochondroma, is described. The resection of the tumor through an extra-oral incision is the treatment of choice. The follow-up covers a period of 4 years. No relapse was observed and postoperatively the function of the temporomandibular joint was practically normal.
