The axial frontonasal flap revisited.

After 15 years of experience and 50 cases, we think that the axial frontonasal flap is of great value for the repair of large skin defects of the nose. This flap mobilizes all the skin cover of the nose located above the defect and the adjacent frontal skin and rotates it on a vascular pedicle existing at the level of the inner canthi. The excess of skin of the glabella is then transferred to the nose, and this large flap allows coverage of the defect without tension or distortion. The long-term results are very good, with a hardly visible repair in 26 of 50 patients, the long scar being very well hidden at the periphery of the nose.

[Radical excision of giant abdominal nevi in infants. Apropos of 3 cases].

Total removal of giant naevi with a minimal residual scar is of course ideal for prevention of malignancy and obvious psychological reasons. One can take advantage of the excess of skin existing in infants to be able to perform such wide excisions with immediate closure. Three cases of abdominal wall excisions in infants are presented, one of the upper abdomen at 9 months, two of the lower abdomen, at 3 months and 6 months. In all cases, a wide undermining was performed to allow the immediate closure. For the two lower abdominal excisions, preservation and transposition of the umbilicus were performed, like on an aesthetic abdominoplasty in adults. The blood loss was minimized by infiltration with epinephrine and meticulous hemostasis. Healing was uneventful. The scars, with a one to two years follow-up, are smooth and fine, and there are no change of contour. Progress in pediatric anesthesiology has resulted in the fact that a large excision and repair in infants presents no more potential dangers than operation performed later. Feasibility of such early wide excisions has been explored in other areas of the body; however, the abdominal wall is the area of choice.

Combined report of problems and complications in 793 craniofacial operations.

We report the experiences in 6 major craniofacial centers, with similar teams but in different parts of the world, in a total of 793 craniofacial operations. The mortality rate was 1.6%. Complications developed in 16.5% of the cases (including infections in 4.4%). This surgery has many potential advantages, not least of which is its psychosocial effects on previously disfigured patients. Certain problems seem inherent, however, for there are not yet any satisfactory solutions to them. Some of the factors that reduce morbidity and improve results include the use of hypotensive anesthesia, a reduction in operating time, rigid stabilization of the mobilized bones at the end of the operation, a diminution in the number of incisions, and extensive antibiotic therapy.

[Fronto-cranial remodeling for craniostenosis with mobilisation of the supra-orbital barr (author's transl)].

33 cases of fronto-cranial remodeling by osteotomies are reported by the authors. Since 1973, 19 oxycephalies have been operated according to an original technique based on two principles:--rocking and advancement of the supra-orbital barr, with an easy lateral retention by a Z-bony cut.--transposition of free bone flaps to rebuild a forehead of the appropriate curvature. The good results obtained have encouraged the authors to operate on young children or even babies in order to solve simultaneously the functionnal and the aesthetic problems. Three plagiocephalies, two trigonocephalies have thus been treated, as well as 5 facio-craniostenosis for whom a 2 cm forehead advancement has been done, the following results being very encouraging.

Radical forehead remodeling for craniostenosis.

A normal forehead has two parts, shaped differently: (1) the lower part (corresponding to the supraorbital rim and glabellar area) set at a steep angle to the nose; (2) the upper part, sloping gently backward. To reproduce this normal anatomy in cases of cranostenosis affecting the frontal area, we found it essential to mobilize and reshape a supraorbital bar of bone and to transfer a suitable piece of the cranial vault in one piece to make a new upper forehead. By this method we have treated 18 patients with oxycephaly since 1973, with good results. We have also operated on babies with craniostenosis to try to solve simultaneously the functional and the cosmetic problems. In faciocraniostenosis, there are dominant malformations at the base of the skull, but an isolated frontal advancement of two cm has produced gratifying early results.

[Total expansion of the orbit for micro-orbitism].

Micro-orbitism which follows the very early arrested development of the optic vesicles hinders the fitting of a prosthesis. A total enlargement of the orbit is proposed which restores the normal dimensions and enables facial symmetry to be re-established. The risks and advantages of this procedure are discussed.

[Problems posed by fixation after Lefort III osteotomy].

The author confines himself to the problems posed by contention after Lefort type III osteotomy. He considers that the posterior iliac crest of the patient may be used to major advantage. Osteosynthesis is essential but it is sometimes possible to avoid maxillo-mandibular block. The results obtained in 18 cases are presented.

Orbital expansion for anophthalmia and micro-orbitism.

In severe cases of microphthalmos or anophthalmos, the bony orbital cavity is often too small to allow one to create a satisfactory socket for a prosthesis. An omnidirectional expansion of the orbit, by osteotomies done in a step-like fashion, allows the creation of a larger bony cavity and improves the symmetry of the face. The risks of the craniotomy and of the mobilization of the free bone pieces are discussed.

Giant breast implant for unilateral aplasia. Case report.

The authors present a patient who had aplasia of the right breast associated with absence of the pectoralis muscles and a chest wall deformity. The insertion of combined breast-chest wall implants improved her appearance markedly.
