The concentric medial thigh lift.

Plastic surgeons often are asked to perform horizontal medial thigh lifts because the skin of this area has poor elasticity, inducing excess skin, and also because there is upper fat deposit. This excess skin and fat lead to irritation and even functional problems. But surgeons dislike this operation because of its justified bad reputation. Obviously, this area is difficult to manage because of the many possible side effects (e.g., healing difficulty, scar migration, necrosis, effusions, pain) and unreliable results. A new way of thinking is proposed to lighten this operation and make its more frequent use possible. This horizontal technique presents several innovating points: -A new incision line located along the labia major in the perineal crease remains at the same height backward. The incision never descends into the buttock fold. -No undermining whatsoever occurs even in the resection area. Liposuction is the key to avoidance of any undermining. It is performed everywhere in the thigh, but most importantly under the resection area where all the fat must be eliminated to lighten the flap and favor its lifting. -The resection removes only the skin layers (epidermis and dermis) and not the liposucted tissue, which is very thin. Consequently, all lymphatic and other vessels are preserved, and the healing process is much easier. Moreover, there is no dead space after ascension of the flap and no risk of effusion. -The resection is realized on demand, depending on the excess of skin brought on the incision line by each anchor suture. Therefore, any tension on the skin closure is avoided. -The direction of the skin stretching is concentric toward the labia minor. Consequently, the length of the scar is shortened at both the front and the rear. -Anchor sutures pull a nonundermined skin, thus drastically decreasing the risk of necrosis. In the past 2 years, 25 patients, most of them as outpatients, have undergone surgery using this technique, with a real improvement in the quality of the result, as compared with the results from the standard technique.

The submental island flap: a new donor site. Anatomy and clinical applications as a free or pedicled flap.

This paper describes the use of a new island flap based on the submental artery. Previously described cervical flaps have inherent problems ranging from limited mobility to unacceptable donor-site scars, to unpredictable outcomes. The flap design and technique were studied on 20 fresh cadavers and 8 patients who underwent radical neck dissections. The flap was then used successfully for reconstruction of orofacial defects in 8 patients. The flap has a long (up to 8 cm), reliable pedicle, and cutaneous dimensions can reach up to 7 x 18 cm. It can be used as a cutaneous, musculofascial (cervicofascial and platysma), or osteocutaneous flap. This flap has an excellent skin color match and a wide arc of rotation, and can extend to the whole homolateral face, except for a part of the forehead and the whole oral cavity. The anatomy, the technique, and clinical experiences are presented.

[Role of osteocutaneous external brachial flap in the treatment of composite loss of substance of the mandible].

The authors report on their research begun in 1987 on this flap and its uses in reconstruction of composite defects of the horizontal and symphysical parts of the mandible, regardless of the cause of the loss. For treatment of average sized defects (less than 7 centimeters), it is reliable flap, easy to remove and to model by osteotomies, giving a thin skin mobile with bone and the removal of which results in only moderate development of scar tissue at the donor site.

[Malignant fibrous histiocytoma of the maxillary sinus. Clinical and therapeutic aspects].

Malignant fibrous histiocytomas, or MFH, have been individualized only since the last two decades. These sarcomas which usually develop from soft tissues are no longer considered rare, except in some of their facial sinus localizations. Two chapters will be particularly developed: the paramount significance of anatomopathological investigations owing to the difficulty in establishing the diagnosis, since MFHs may be mistaken for benign processes; the treatment which is, generally speaking, the same as for bone sarcomas.

Remodeling bodylift with high lateral tension.

Body lifts are surgical procedures that are infrequently performed because the length of operating time increases the risk to the patient as well as the likelihood of surgeon fatigue. The other drawback of body lifts is the long incision line. However in our experience, these incisions are well accepted if they are well placed and if the results of body change is significant. The goal of this paper is to show how operating time can be shortened and the scar be correctly positioned by using precise preoperative markings. In addition to high superior tension abdominoplasty, the two innovations of this type of body lift are the dermal fat flap and the suspension of tissue in the trochanteric and buttock regions. Meticulous hemostasis limited undermining, and the closure of dead space are factors that produce a more reliable procedure, both in terms of postoperative problems and the final results.

High superior tension abdominoplasty.

Although abdominoplasty has always been a routine operation, demands for it are constantly increasing for diverse reasons. For one, stomach reduction practiced by digestive surgeons is becoming a regular procedure. Massive weight loss induced by this surgery leads to a demand for abdominoplasty with increased risks of a difficult postoperative period and complications. In addition, more and more patients are looking for an improvement of a moderate cutaneous excess following pregnancy. In this case, standard abdominoplasty technique does not permit a sufficient skin resection and the surgeon must perform a vertical below umbilical scar and an insufficient epigastrium tension. Finally, a hematic or lymphatic collection is obviously undesirable and can lead to an aesthetic disaster. For these reasons, surgeons, more than ever, need a reliable technique that adapts to those different situations.
