[The nasolabial flap and the buccinator flap. Anatomic study and 2 cases reports].

The authors present an anatomical study of the nasolabial flap and buccinator flap on 12 cadavers. This study was illustrated by 2 clinical cases: a case of reconstruction of the philtrum with a superiorly based nasolabial flap and a case of reconstruction combining an inferiorly based nasolabial flap and an ipsilateral anteriorly based musculomucosal buccinator flap.
