Oral commissure reconstruction with orbicularis oris elastic musculomucosal flaps.

Surgical reconstruction of the oral commissure aims to restore both symmetry of the lips at rest and, more importantly, full oral competence. Moulding the lip commissure with functional and cosmetic fidelity remains till today a difficult task. A possible surgical solution, the 'elastic flap' principle described by Goldstein, may be found in the wide full-thickness mobilization of the upper and lower vermilion as two composite myocutaneous flaps - tissue sandwiches consisting of labial skin, orbicularis oris muscle and oral mucosa - on the axial pattern of the superior and inferior labial arteries. Based on the contralateral commissure, both flaps are easily 'stretched', accordion-like, to reach the predetermined point of the new commissure, using to full advantage the inherent elastic potential of both vermilions. The fibres of the orbicularis oris muscle at each end of both flaps are embricated to reconstitute a neo-modiolus, which is anchored to the residual buccinator muscle in primary reconstructions, or to the available peri-oral fibrous tissue in secondary procedures. The authors present a select group of 22 patients, who, between 1993 and 2008, underwent this reconstruction procedure for primary or secondary defects involving the oral commissure. The results were generally satisfactory, both functionally and cosmetically. The advantages of this procedure include full restoration of the dynamic function of the orbicularis ring in a single-stage operation and avoidance of either lipswitching procedures or of mobilization of mucosa and cheek skin. The final scars remain well camouflaged within the oral mucosa and the mucocutaneous junction of each lip.

[Fournier's gangrene: remarks on two clinical cases]. / Le gangrène de Fournier: remarques sur deux cas cliniques.

Fournier's gangrene is a genital and perineal necrotizing fascitiis with a rapid evolution. It's an affection caused by aerobic and anaerobic micro-organisms, eventually associated with a superinfection by micetes. It has characterised by a deep oedema associated with lancinating pain and itching in external genitalia, rapidly evolves to perineal tissues necrosis and purulence. At this stadium patient's general conditions are still serious and patient may be comatose. When toxaemia is over, demarcation of necrotic areas can be remarkable and granulation start growing. Fournier's gangrene seems to be related to an ischemic necrosis caused by obliterative endoarteritis and thrombosis of internal pudendal and deep and superficial external pudendal artery. The infection gateway may be subcutaneous tissue lesion associated to trauma or surgical procedures in immunodeficient organism. Diagnosis is mainly clinical but a superficial ecography could be useful to demonstrate thickening in subcutaneous tissue with normal testicles. Both of them were middle aged males, heavy smokers, affected by hypertension and COPD. In both cases there was polymicrobial Gram positive bacterial infection. Antibiotic systemic therapy and topic therapy were administered. The patient also received hyperbaric oxygen therapy. Thirteen days after the admittance, the infection was defeated and we could start the surgical cover. To cover the scrotal wound we have used split-thickness skin grafts taken from the right thigh. These grafts took at 100% and the patient was discharged seven days after surgical operations. Follow-up at six months and at one year showed any functional limitation and a good aesthetic result.
