Scar-length reduction by ring-shaped expansion.

Conventional tissue expansion with rectangular or round expanders often results in considerable dog-ear formation and, after resection, in lengthening of the final scar. The resulting scar is, always much longer than the maximal diameter of the skin lesion. These disadvantages are partially avoided by the use of croissant-shaped expanders. Taking the idea of the croissant-shaped expander and thinking further in terms of differential expansion, a new expander has been designed. It consists of a ring-shaped expander that is placed under the normal skin around the lesion. When the appropriate expansion is reached, the skin lesion is excised and the defect is closed with a running subcuticular suture, pulling as much skin as possible centripetally. The resulting scar is shorter than the maximal diameter of the skin lesion. The new expander has been tested in two patients in regions that are reputed for poor scar quality (the back and the upper arm). The results are encouraging.

Dermatoglyphic analysis of primary and secondary cleft palate patients.

No significant differences are found among the different groups. Some of the observed minor differences between the cleft and the control groups may be the result of sampling error. Our findings are not surprising because our cleft patients have no other congenital anomalies. Indeed aberrant dermatoglyphic patterns are found mainly in generalized dysmorphogenesis, such as in chromosomal syndromes, rather than in isolated congenital malformations, exception being made of course for congenital malformations of the hand itself.

Esthetic blepharoplasty.

Esthetic blepharoplasty is the operation designed to correct excess skin and/or pseudoherniation of fat in the eyelids. These eyelid changes give the pateint a tired look and make him or her look (prematurely) old. The indications and contraindications for the procedure are reviewed. The possibilites and the limitations of the operation must be thoroughly discussed with the patient preoperatively. A psychological evaluation of the patient must be carried out by the surgeon in order to discard unsuitable candidates for the operation. The esthetic blepharoplasty is performed under local anesthesia, completed by intravenous sedation. The operative technique is outlined and consists of judicious skin excisions and resection of fat from the differenct orbital compartments. Atraumatic technique is of utmost importance. Complications are rare in experienced hands but are almost unavoidable in inexperienced hands. Ectropion of the lower eyelid is the most common complication. The cause, prevention and treatment of possible complications are discussed. If carried out properly in a well selected patient by a competent plastic surgeon, the esthetic blepharoplasty gives very satisfying results.

Orbital fractures.

In this paper the importance of the clinical, ophthalmological and radiological examination in the diagnosis of orbital fractures is stressed. Indications for operative treatment can be esthetic or functional, such as enophthalmos or diplopia. A plea is made for early diagnosis and treatment. An open approach is used for all displaced fractures in order to obtain an anatomical reduction. Currently, miniplates and screws are used more frequently for stabilization. Defects in the orbital floor should be covered preferably with autogenous bone or, if unavailable, with bovine cartilage or some synthetic material.

Soft tissue trauma of the face.

In this paper the principles of primary care of soft tissue trauma of the face are outlined. The importance of a complete preoperative evaluation is stressed. Atraumatic technique, conservative debridement, reconstruction of anatomical landmarks, coverage of skin defects and removal of foreign bodies are essential. Lesions to deep structures and associated facial fractures should, if at all possible, be repaired at the time of soft tissue repair. Special attention should be given to eyelid repair. Lesions to the lacrimal duct system, to the canthi and to the levator muscle should be dealt with primarily.

Soft tissue defects of the lower extremities.

Based upon our experience with 459 skin and soft tissue defects of the lower extremities, of which 326 were covered surgically, the different etiologies of these defects are listed and the factors influencing the choice of a method of coverage are discussed. The advantages and disadvantages of the different reconstructive methods are reviewed and illustrated with representative cases.

Subcutaneous mastectomy, indications and techniques.

In this paper the indications, the technique and our personal experience with 45 subcutaneous mastectomies (S.C.M.) are reviewed. A bilateral S.C.M. is mainly a prophylactic operation, indicated in patients with premalignant breast disease and in high risk patients with widespread fibrocystic disease. A unilateral S.C.M. is indicated in patients who have already had a mastectomy for carcinoma and whose remaining breast has an increased risk for also developing a carcinoma. The technique which we nowadays prefer, consists of a S.C.M. with immediate submuscular prosthetic reconstruction. The operation is done through a transverse incision for small non ptotic breasts and following a Mc Kissock reduction mammoplasty pattern for large ptotic breasts. The nipple-areola complex is transposed on a wide dermal pedicle. Both the subcutaneous and submuscular spaces are drained and early postoperative mobilisation of the prosthesis is advised. Our experience with 45 subcutaneous mastectomies is reviewed. The complications have been few and occurred mainly in earlier cases where the prosthesis was inserted subcutaneously. Neither necrosis nor circulatory embarrassment of nipple-areola complex were encountered.
