Prefabricated flap composed by skin and terminal gastromental vessels. Experimental study in rabbits.

Background: The angiogenic induction property of the omentum makes it a promising pedicle for prefabricating flaps. Therefore, the objective of this paper is to establish the abdominal area to be prefabricated by the omental pedicle and to analyse the prefabricated potential (PP) according to the time delay between the pedicle introduction and the flap release.

Methods: Forty-four rabbits were divided into four groups (A, B, C and D).

Expanded median forehead flap and abbé flap for nasal and upper lip reconstruction after complications of polymethylmethacrylate.

Despite the benefits from the minimally invasive technique, complications may occur, raising doubts about the safety of polymethylmethacrylate as an injectable filler material. The authors report their treatment of a patient from another institution with necrosis involving full-thickness nasal skin and upper lip after injection of polymethylmethacrylate in the nasolabial folds and nose for augmentation. An expanded median forehead flap was used to reconstruct the nose, and an Abbé flap was used for the upper lip.
