Use of Dermal Grafts in Reconstructing Deep Nasal Defects and Shaping the Ala Nasi

Abstract

Background. Deep postsurgical defects on the nose and alar rim pose a challenge to repair. Several techniques are available to reestablish normal contour. If a depressed area is anticipated, dermal grafts can be used to fill the defect and soften contour irregularities. The technique is simple and can prevent the need for a more complicated repair. Objective. To reestablish normal contour over nasal defects by using dermal grafts as a tissue filler in conjunction with graft and flap reconstruction. Methods. Fifteen patients had contour deformities that could be improved with dermal graft insertion under their full-thickness skin grafts or flaps. Fourteen of these patients had nasal defects and one had a vermilion border defect that resulted from tumor removal by Mohs surgery. Patient selection, dermal graft harvesting, and surgical technique are described. Results. All patients showed cosmetic benefit from dermal grafting. Contour was improved in each case. Fourteen patients had no significant complications. One flap showed tip necrosis in a patient who was a smoker. No resorption of the dermal grafts occurred over the 1- to 9-month follow-up period. No cyst formation occurred. Conclusion. Dermal grafts can be used during the initial repair of postsurgical nasal defects. These dermis grafts effectively fill the defect and restore contour. The technique is simple, easily mastered, and can obviate the need for more complicated repair.
