[Valvular tube gastrostomy].

Valvular tube gastrostomy was performed on 90 patients whose lesions necessitated permanent alimentary gastrostomy. 60 were cases of cancer of the oesophagus where the tumor could not be removed, and 30 were cancers of the oropharynx. 10 (11 p.cent) died within one month of surgery, but slackening of the sutures was an attributable cause in none of these cases. 4 succumbed to their cancer before the sixth month. The functional results of those surviving more than 6 months were examined: -- 75 p.cent had very good results; -- 17 p.cent had mediocre results, but feeding was still possible; -- 8 p.cent had bad results and a second operation was necessary.

Augmentation cheiloplasty by using mucomuscular flaps.

If one excludes the controversial use of silicone injections and the not fully researched new biomaterials for implant (e.g., Gore-Tex), there are no lip augmentation techniques that give stable and lasting results. Collagen and dermal or fascial grafts are almost always reabsorbed. Local flaps (either W or V/Y) give only a slight outward protrusion of the lips and do not increase volume and therefore have negligible cosmetic impact. In plastic surgery flap rotation is standard practice when the objective is stable tissue reconstruction. We feel that this technique achieves lasting increases in lip volume. Therefore, we propose the rotation of a mucous-muscle flap obtained from the inner cheek wall or from the other lip, the fulcrum of which is the labial commissure. The surgical technique is given in detail here together with the results and complications of 28 cases.
