Abstract
Background: Skin cancer is the most common of all cancers. Mohs surgery is an effective technique for removing common types of skin cancer. The number of patients presenting for reconstruction after Mohs surgery has been increasing in recent years. Reconstructive surgeons are faced with diverse defects of different sizes and locations. The aim of this study was to examine reconstructive methods for Mohs defects to aid in preoperative planning.
Methods: We reviewed the charts of 245 patients who underwent Mohs defect reconstruction over a period of 5 years. The patients were categorized according to the reconstructive technique (eg, flap, full-thickness skin graft, split-thickness skin graft) used in relation to anatomic location and the size of the defect.
Results: One hundred twenty-nine patients (53%) had Mohs defects of the nose. Bilobed flap reconstruction was the most common for the nasal ala (17/42 [40%]), tip (19/41 [46%]), and nasal sidewall (8/25 [32%]). Forehead flap reconstruction was most common for nasal dorsum defects (9/16 [56%]). Linear closure was the most common reconstructive technique for the cheek (18/34 [53%]), the forehead (13/20 [65%]), the chin (4/4 [100%]), the lower lip (4/4 [100%]), the upper lip (8/13 [38%]), the auricle (4/10 [40%]), the eyelid (5/8 [62%]), and the temporal region (2/5 [40%]). Composite grafting was the most common in the nasal columella (2/3 [67%]) and full-thickness skin graft for nasal sill defects (2/2 [100%]). Split-thickness skin graft was the most common in the scalp (3/6 [50%]).
Conclusions: Various options exist for Mohs repair. Understanding trends of reconstructing Mohs defects may help in planning the best method of reconstruction.
