ABSTRACT

OBJECTIVES: analyze the importance of the myocutaneous flap of nasalis muscle of the nose in the reconstruction of skin defects of the nasal tip. This is a retrospective study concerning 15 patients treated from 2010 to december 2012 for basal cell carcinomas of the nasal tip. The minimum follow up was 6 months. We describe the procedure and the indications. The best site to be proposed for this flap is beyond question the latero-medial part of the nasal tip. It can be adapted to skin defects as large as 15 mm. Obviously since it is a skin island flap it is important to respect the pedicle between it and the nasalis muscle. The closure of the donor site is done in the alar-facial sulcus with a VY suture and scarring on this level is very negligible. We analyzed the aesthetic result which is often very good. One advantage of this flap is not to change the architecture of the nasal ala.
