Use of a versatile axial dorsonasal musculocutaneous flap in repair of the nasal lobule.
We present our 17 years of experience in using a sliding axial musculocutaneous flap from the nasal dorsum in the repair of 53 nasal lobular defects (follow-up 3 to 212 months, mean 47.3 months). This flap is a modification of the classic Rintala flap but is based on a greater understanding of surgical anatomy, the biomechanical properties of skin, and physiology of flaps, all of which allow a more aesthetically satisfactory closure of very distal nasal lobular defects. After excising the tumor, two parallel incisions are made along the sides of the nasal dorsum, and flap is raised in the gliding plane deep to the fibromuscular layer of the nose and superficial to the cartilage and bone and then advanced over the defect, which can be as large as the entire nasal lobule. The flap is very reliable (no failure in our series) and easy to perform; furthermore, it is a fast, one-step reconstructive procedure that leaves the scars in areas of natural shadow. This flap makes use of a wide dorsal and glabellar undermining to recruit sufficient skin; it takes advantage of the mild tension exerted by the underlying nasal framework to lengthen the flap reliably without the need for an extra incision or Burow's triangles, as originally described by Rintala. Neither tip rotation nor glabella flattening has ever been found to be a real problem in our series because the flap elongates in a period of 2 to 6 weeks and tip always comes down, provided that the nasal framework is not modified. We believe that the axial musculocutaneous sliding flap has distinct advantages over other alternative local flaps in the repair of lobular nasal defects; moreover, although this simple operation cannot compete with the quality of the aesthetic results achieved by very skilled masters using frontal flaps, it is an easy, quick, one-step procedure that allows acceptable and reliable aesthetic results to be achieved by the majority of surgeons, and it does not harm the precious forehead donor site, which may become essential in case of the need for further reconstruction.
