[Nasolabial flap in the repair of partial transfixing loss of substance of the nostril].

The nasolabial flap has frequently been used in many ways to repair the nostril. It has also been the subject of numerous criticisms, essentially related to the poor quality of the results obtained. However, the authors consider that it has an important place in the treatment of partial transfixing defects of the nostril. The nasolabial flap must be performed according to certain precise rules: strictly nasal superior pedicle, defatting of the entire flap, rotation of the flap around the external extremity of the pedicle, plication of the flap and modelling to recreate the alar margin and to reconstitute the lining. Several clinical examples illustrate this use of the flap and allow the indications to be defined.
