Maintaining Contour on Convex Surfaces: 2 Surgical Techniques for the Lateral Nasal Ala and Bald Scalp

Maintaining contour on convex surfaces is important to achieve a good cosmetic outcome after Mohs micrographic surgery. Defects of the lateral nasal ala and bald scalp are noticeable if the surface contour is disturbed. We present 2 simple techniques designed to maintain the surface contour at these 2 sites after Mohs micrographic surgery and provide excellent cosmesis. One technique involves the use of an intramuscular hinged flap to restore depth to a deep lateral nasal ala defect to maintain its surface contour. The second technique uses a dermal island to restore the convex surface on a bald scalp.
