[Frontal stage in cervicofacial lift: the "helmet crest" technique associated with rapid expansion].

The frontal level is generally the less and the last concerned in facial ageing and the classical incisions of the cervicofacial facelift provide no changes in the frontal and glabellar wrinkles. To avoid such residual defects, the authors perform for the lost ten years an important push back of a central band of the vertex (the so called "Helmet crest") by means of a bilateral triangular excision subsequently closed by VY. This push back needs a very large undermining in the subgalea plan, from the eyebrow and glabellar region to the crest of the hemet itself. The VY closure is now really facilitated by a rapid expansion obtained by a special T shaped expander which allows not only cutaneous expansion but also aponeurotic expansion of the reputedly inextensible galea. This technique avoids the coronal incision and its serious sequelae and may be carried technique out at the same time as cervicofacial face lift. It allows a personal, equilibrated tension of the facial mask which is the essential condition for a good presentation of natural expression of the face.

[The middle third of the face in facial lift: lipopexy of the premalar fatty pad].

UNLABELLED: The technique proposed tries to resolve an irritating problem which has been incompletely and illogically resolved until now: the restoration of the natural relief of the middle third of the face. An anatomical study shows that the malar region is an eminence composed of a double structure, bony and fatty. The ptosis of what the authors propose to call "the premalar fatty pad" is probably the earliest sign of ageing in the face. It give a skeletal appearance and fills the canine fossa which become a heavy fold and increases the apparent depth of the naso genio labial sulcus. The aim of this technique is to restore a normal appearance by restoration of the true anatomical structures. The technique consists of extensive undermining behind the ptotic fatty pad, in front of the malar bone and SMAS as fas as the orbital rim which allow displacement upwards and backwards. Resorbable sutures and an accurate skin tension ensure the new premalar position of the fatty pad. Posterior fibrosis, in the undermining, will be the essential means of late fixation. 70 such operations with sufficient follow up have been carried out. The result is stable in 58 of them and insufficient but appreciable in all of the others. Fatty faces give poor results due to the poor quality of the skin. CONCLUSIONS: it is a simple, logical and efficient procedure, more often performed in association with the treatment of frontal and cervicofacial level of the face. No complications related to this procedure have been observed.

[Double triangular resection technique at the feet of the cartilaginous arch in the correction of the nasal tip. "Do not touch the dome"].

Retropulsion and modelling of the nose tip can be obtained very simply without touching the dome by means of double triangular resection at the feet of the cartilaginous arch formed by the two alar cartilages. Static and dynamic effects are obtained retropulsion, elimination of the prominence of the superior border of the alar cartilage (without shortening resection) allowing creation of a finer nose tip; rounding of the nasal orifices, improving respiratory function; suppression of labial dependence of the tip a factor responsible for secondary ptosis of the tip.

[The gracilis muscle as musculocutaneous flap. Evaluation of 20 cases].

The use of gracilis as muscular or myocutaneous flap is very well-known. The authors report 20 cases of gracilis flap including 13 reconstructions of the vaginal cavity following extended abdomino-perineal resection. Some technical points concerning the localization of the cutaneous part of the flap and the pedicle dissection are discussed. The use of gracilis flap is still limited in surgical teams following extended abdomino-perineal resection, nevertheless it is a very useful flap because of its low morbidity, the shortening of patient hospitalization and the very satisfying aesthetic result of the neo-vaginal cavity.

[Suture, cicatrization and scars].

A suture must comply with precise rules in order to produce an acceptable scar. A distinction must be drawn for "malhealing" between defective and pathological scars. The study of the intimate processes of healing allows understanding genesis and guiding their treatment.

[Advertising and medical responsibility in esthetic surgery].

Even in cosmetic surgery, medical law does not define any obligation in terms of results, but an obligation in terms of methods and information. As cosmetic surgery is an elective procedure, if it is induced as a result of publicity considered to be abusive, this obligation of methods could become an obligation of results. A rigorous approach to information is the only way to ensure that it is not confused with publicity.

[Tissue losses of the heel].

Regional island fasciocutaneous flaps are the method of choice for the treatment of skin defects in the heel. They give good functional results with minimal esthetic sequelae.

[Reconstructive dermolipectomy of the abdominal wall. Experience with 600 cases].

Experience with 600 operations, including 200 second-look operations, for the management of lipodystrophy, fatty excess and other unsightly affections of the abdominal wall allows defining a few essential elements. The routine procedure consists in lowering the supraumbilical curtain down to the pubis after transposition of the umbilicus. This is indicated in case of considerable supraumbilical skin excess, and requires spreading the board flap with properly distributed tensions. The achievement of a beautiful curve must prevail upon the position of the scar, which is however located in the inferior abdominal crease as a rule, extending up the iliac crests. If there is less supraumbilical skin, minimal procedures can be considered, also with the major aim of obtaining a sightly curve. On a whole, it is important to emphasize that obtaining a small scar is not a goal in itself, the true hope being the restoration of a satisfactory curve of the abdominal wall.

[The contribution of genioplasty in esthetic surgery of the face].

The chin position in overall facial aesthetics is well known and it has an important influence on personality and relations with others. For most plastic surgeons, genioplasty is limited to chin advancement with alloplastic implants. Sliding horizontal osteotomy of the mandibular symphysis is not well known: the technique is simple, fast and safe. Indications are multiple (augmentation, reduction, straightening, lengthening). Improvement is both aesthetic and functional (labial gap). In deficiencies of the submental region, genioplasty may be compared to muscular transposition. Several cases of aesthetic and orthognathic surgery are presented to emphasize the value of the procedure.

[A permanent expanding prosthesis and the latest refinements in breast reconstructive surgery].

The use of an expanding prosthesis that can be left in place after adjustment of its volume allows an improvement in the quality of the results of breast reconstructive surgery. This implant offers many advantages: 1) It doesn't have to be changed: only the valve and the inflation tube must be removed. 2) The ideal breast volume can be progressively obtained by gradually prompting the skin. 3) A transient overinflation before returning to the desired volume often results in a more natural looking and preptotic breast. An adjuvant method (tattooing of the nipple-areola) is also presented. It contributes to the improvement of the aesthetic nature of this type of reconstructive surgery. The author's series consists of 26 reconstructions which demonstrate the interesting possibilities offered by this implant and by the adjuvant method applied to the nipple-areola.

[Successful separation in 1974 of craniopagus twins united at the vertex. Indications, technics, follow-up after 14 years].

On July 22, 1974, 55 days after delivery, the separation of female craniopagus twins united at the vertex was performed. This case was very similar to the case published by Voris in 1957 after separation in 1955. Surgery was decided because the neurological examination was normal in both twins, because there was no body malformation, because the angiogram as well as isotopic scintigraphy showed two normal brains, two superior sagittal sinuses and two torcular areas with a short venous union in the middle of the bone defect. In addition, Sophie and Sonia were suffering from respiratory disturbances due to their position. Surgery was easy (90 min) using the operative microscope; intubation and placing intravascular tubes for hemodynamic monitoring were difficult and lasted 4 hours. After all it took 14 years and 23 operations to complete the reconstructive surgery of the bone and skin. Cranioplasty was finally performed using vitallium plates. On their 14th birthday a neuropsychological investigation was performed with an IQ of 94 in Sophie and 76 in Sonia. Both girls are nubile and enjoy a normal school attendance.

Characterization of the collagen of human hypertrophic and normal scars.

The collagen produced in response to an injury of human skin is initially stabilized by a cross-link derived from hydroxyallysine, and characteristic of embryonic skin. In normal healing there is a change over with time to the cross-link derived from allysine, which is typical of young skin collagen. In contrast, hypertrophic scars fail to follow the time-related changes of normal skin, but retain the characteristics of embryonic collagen, indicating a continued rapid turnover of the collagen. This is further supported by the high proportion of the embryonic Type III collagen present in hypertrophic scars.
