[15 years experience with microvascular free tissue transfert for repair of head and neck cancer defects].

We present the modalities and results obtained with free flap reconstruction of head and neck cancers defects. This retrospective review of 165 free transfers performed between 1984 and 1999 included 89 radial forearm flaps (54%), 38 latissimus dorsi flaps (23%), 28 osteomyocutaneous flaps (17%), 6 omentum flaps (4%), 2 jejunum flaps, and 2 cutaneous scapular flaps. Indications were orobuccopharynx (34%), hypopharynx (24%), mandible (17%), craniofacial (15%) and skin (10%) defects. Flap failure rate was 9%. Reconstruction of a radiated site was a statistically significant indicator of flap failure. Four types of free flaps were preferred for reconstruction of head and neck cancer defects. The radial forearm flap was used as a lap flap for the orobuccopharynx, the tubuled radial forearm flap for reconstruction of the digestive tract after total pharyngolaryngectomy, the osteomyocutaneous free fibular flap for pelvimandibulectomy, especially for the anterior arch, the latissimus dorsi flap to fill craniofacial defects, and the free omentum flap for craniofacial complications after radiotherapy.

[Reconstruction of the palate vault by free forearm cutaneous flap in oncology].

Surgical reconstruction after partial superior maxillectomy raises a major functional challenge and postoperative recovery implies difficult prosthetic rehabilitation. Between 1989 and 2000, 23 free radial forearm flap reconstruction were performed for palate defects. Twenty-two patients were treated for cancer-related defects and one patient for a non-malignant tumor. Immediate reconstruction was performed in 21 cases and delayed reconstruction in 2. Radiation therapy had been given prior to surgery in 7 patients, Flap necrosis occurred in 2 patients who had surgery alone. Deglutition and phonation outcome was satisfactory in all patients. Trismus was the most frequent complication (7 cases). The free radial forearm flap is the gold standard surgical treatment for superior maxillary defects. In these patients, and exclusive skin flap enables complete reconstruction.

[Hamartomatous adiposity of the thyroid].

Report of one case of hamartomatous adiposity of the thyroid gland. Only eight cases have been reported. The lesion is composed of thyroid tissue and mature adipose elements. Previously reported cases are reviewed and the pathogenesis is discussed.

[Sensory illusions in hang-gliding].

Sensory illusions in hang-gliding and para-gliding. Hang-gliding and para-gliding are at the moment booming sports. Sensory illusions are physiological phenomena sharing the wrong perception of the pilote's real position in space. These phenomena are very familiar to aeroplane pilotes, they can also be noticed on certain conditions with hang-gliding pilotes. There are many and various sensory illusions, but only illusions of vestibular origin will be dealt with in this article. Vestibular physiology is reminded with the working principle of a semicircular canal. Physiology and laws of physics explain several sensory illusions, especially when the pilote loses his visual landmarks: flying through a cloud, coriolis effect. Also some specific stages of hang-gliding foster those phenomena: spiraling downwards, self-rotation, following an asymetric closing of the parachute, spin on oneself. Therefore a previous briefing for the pilotes seems necessary.

[Cystic duplication of the esophagus, a rare etiology of dysphagia. Apropos of a case].

A case of an upper oesophageal duplication in a 44 year old man was reported. Dysphagia was the only clinical signs and further examinations CT Scan, MRI performed for diagnosis. Surgical treatment (thoracotomy) was performed and postoperative complication was underlined. Cysts with oesophageal structure are unusual anomaly and surgery is difficult and dangerous.
