[The Abbe-Estlander flap: anatomic basis, surgical technic and indications for lip repair].

The Abbe-Estlander flap is a full-thickness lip-switch flap rotated from mid lower lip to fill defects of the upper lip. In 1872, Estlander emphasized the importance of this flap. Abbe, in 1898, was the first to switch a lower lip flap into the upper lip for a cleft deformity. The lip-switch flap is an arterialized flap, based on the constant inferior labial artery. This flap is widely used to repair the defects from cancer and traumatism or in repair of the cleft lip deformities.

[The value of ultrasonographic monitoring in mandibular lengthening using the Ilizarov principle. Preliminary results].

From a review of the literature and a clinical case, we demonstrate the value of ultrasonographic monitoring of mandibular distraction according to the Ilizarov's protocol. Unlike X rays, sonography offers early and reliable pictures of the ossification process. The ultrasonic image matches the histological aspect obtained in the course of experiment. A more accurate monitoring of the regenerating area is thus made possible.

[Moebius syndrome: therapeutic proposals from 2 cases].

Moebius syndrome is a congenital bilateral palsy of the sixth and seventh cranial nerves. It results a total absence of facial expression and a severe strabismus. Social life is greatly disturbed. Other anomalies may be associated, especially other cranial palsies and Poland syndrome. The etiology of this syndrome isn't clearly established. Stem necrosis secondary to a vascular deficiency is often admitted. We report two observations. We emphasize the importance of a complete maxillo-facial treatment including maxillo-mandibular anomaly. Both patient underwent orthognathic surgery. The first one for class II and the second for class III anomaly. One patient underwent a facial reanimation by temporal muscle transfer. Orthognathic surgery must be realized prior to facial reanimation. A correction of the strabismus is possible. Moebius syndrome is a rare (200 observations) but very severe malformation. Maxillofacial surgery is able to improve the morphological and relational aspect of Moebius syndrome.

Acute normovolaemic haemodilution does not reduce the inflammatory process induced by facial surgery.

The place of preoperative acute normovolaemic haemodilution (haematocrit = 28%-32%) in reducing postoperative inflammation was evaluated after facial surgery. Thirty-two patients scheduled for mandibular osteotomy were randomized to a nonhaemodiluted group or to a haemodiluted group. The degree of postoperative inflammation was evaluated: first by an x-ray technique (radiotelemetry) providing measurements of the tissue thickness (quantitation of facial oedema), and second by the measurement of four acute phase protein plasma concentrations during the first postoperative week. Throughout the study, no changes in facial oedema or in variation of acute phase proteins were detected after haemodilution. It is concluded that acute normovolaemic haemodilution has no effect on the intensity of facial oedema and the biological inflammation process after facial surgery.

[The gastro-omental flap: a secreting mucous flap for reconstruction of the oropharynx and the oral cavity].

The gastro-omental flap consists of a patch taken from the greater curvature of the stomach and the bordering omentum. It is based on the right gastro epiploic vessels and is used as a free flap for intraoral reconstruction after resection of oral carcinoma. Twenty patients underwent gastro-omental flap. The operative technique is described. The evaluation consisted in questioning, chemism on the salivary flow and biopsies. There is no morbidity related with the donor site. The gastro-omental flap avoids post irradiation xerostomia. Oral irritation and bleeding of the flap may occur.

[Amyloid disease and extreme macroglossia. Apropos of a case].

A case of extreme macroglossia was observed in a patient with amyloid disease and dysglobulinaemia. A medial diamond-shaped glossectomy was required to reduce the size of the tongue. The details of the surgical and anaesthetic procedure are presented. This type of surgery, greatly appreciated by the patient, can only be undertaken after careful preparation. The reported cases are rare and the indication for surgery is difficult due to the unpredictable nature of the local and general clinical course of the disease.

[Osteotomy of the median tubercule as a consequence of bilateral complete labio-maxillo-palatal cleft].

In the bilateral total labio-maxillary cleft the premaxilla is sometimes very protrusive at the completion of facial growth. This kind of malposition cannot be treated by orthodontics. Surgical repositioning of the premaxilla with simultaneous bilateral alveolar maxillary bone graft is done before the revision of lip and nose. Its goal is the reconstruction of a solid and harmonious dental and maxillary arch, closure of bucconasal fistulas, improvement of facial profile by closure of nasolabial angle. The authors describe the operation technique and illustrate it by two cases.

[Hydroxyapatite in orthognathic surgery. Animal experimentation and clinical applications].

Bone cell conduction can occur within hydroxyapatite, a biocompatible, bioactive, synthetised ceramic material, when it is placed in contact with bone tissue. Results of experimental and clinical studies on maxillary osteotomy incisional lines have confirmed these properties, the quality and stability of the results and the good tolerance of this biomaterial making it a product of choice as a substitute of iliac bone grafts, when no longer indicated in this context.

[Osteomuscular serrato-costal free flap: application to mandibular reconstruction].

The serrato-costal free flap provides a large costal flap vascularized by a digitation of the serratus anterior muscle supplied by the dorsal thoracic artery. The flap is easy and rapid to raise with low morbidity. The repair obtained is functionally very satisfactory, but does not allow insertion of an implant. Six cases are reported. The indications of this technique of mandibular reconstruction are discussed.

["Cyrano" angiomas].

Hemangioma of the nasal tip (Cyrano nose) is a cavernous or capillary cavernous form. Its development is related to immaturity. It occurs in infants a few days after birth, and increases with regularity. The natural outcome is favorable, and the angioma decreases in most cases after 5 or 6 years of age. Due to the location and the aesthetic prejudice involved, the parents often ask for early surgical treatment. A study of 4 cases and a literature review indicate the surgical intervention should take place later, ie one should wait and only operate on the sequelae resulting from the development of the hemangioma. Late surgical treatment led to resection of the remaining lesion and to repair of the nasal tip.
