[Mandibular reconstruction by composite musculocutaneous flap in glossopelvimandibular excisions].
Results of 14 mandibular reconstruction by a composite muscular flap of the pectoralis major and trapezium muscles during widespread glossopelvimandibular excisions are described. The technique employed is outlined, emphasis being placed on the need to observe strict precautions during removal and application of the bone component, to avoid accidental avulsion during reconstruction which could compromise the musculoperiosteal vascularization of the graft. Results are sufficiently encouraging for this type of reconstructive surgery to be proposed in all cases where mandibular repair is necessary after interruption of continuity.

The reduction of zygomatic fractures using a straight mouth gag.
A technique is described for the elevation of depressed fractures of the zygoma using the straight mouth gag of Terrier, which is especially suitable for treatment of partly healed fractures.
[Xeroderma pigmentosum. Therapeutic indications on the basis of 3 cases seen recently (author's transl)].
This condition is a genodermatosis, seen chiefly around the shores of the Mediterranean, characterised by early pigment disturbances which progress virtually inexorably towards a diffuse epitheliomatosis which usually results in death before the age of 20 years. Progression of the lesions is precipitated by exposure to UV rays. These lesions are seen essentially in exposed areas, in particular oculopalpebral. Treatment is first preventive (decrease in exposure to sun and protection). Otherwise, surgery remains the most effective method: either excision as required, or extensive cervicofacial prophylactic excision followed by grafting.
