摘要

Reconstruction of nasal defects after tumor clearance with Mohs surgery is a common situation faced by dermatologic surgeons, because basal and squamous cell carcinomas of the nose account for up to 64% of nonmelanoma skin cancers of the face. Nasal defects can be challenging to repair. Minimal alterations to, or minor asymmetry of, this prominent midline structure of the central face could result in significant changes to overall appearance. Nasal supratip defects are often repaired by a variety of methods, including second intention healing, grafts, and flaps. Although aforementioned repairs may provide excellent functionality and cosmesis,a less complicated primary closure can also produce an exceptional result, even for larger defects greater than 1 cm. Primary linear closure may also result in decreased morbidity to the patient.Primary linear closures are the mainstay of dermatologic surgery. Although flaps and grafts are often creative and frequently employed in nasal reconstruction, primary linear closures offer several advantages. Using the basic principles of dermatologic surgery, primary closures are much simpler to perform than grafts or flaps, usually resulting in a faster repair, decreased wound exposure time, and less risk of necrosis. In addition, primary linear closure results in fewer scars that extend into different cosmetic subunits, often leading to a more aesthetic result.Although primary linear closures on the nasal dorsumare often considered for small defects, this design is often disregarded for larger defects due to anerroneous expectation that distortion of the nasal tip or alae may result. We present two examples in which large post-Mohs micrographic surgery defects of the nasal supratip were-closed primarily with an excellent final outcome.
