RESUMO
BACKGROUND: Currently, there are limited reviews in the dermatology literature on how to approach reconstruction of nasal lining in full-thickness nasal defects resulting from Mohs micrographic surgery. Given variable training and experience, dermatologic surgeons may seek additional references to help reconstruct certain advanced defects. We sought to synthesize literature from dermatologic surgery, plastic surgery, and otolaryngology to review repair options and considerations for repair of nasal lining defects. OBJECTIVE: To present a comprehensive literature review of repair options for nasal lining reconstruction and discuss advantages, disadvantages, specific anatomic considerations, and techniques to execute such options. MATERIALS AND METHODS: Articles from several different reconstructive specialties including dermatologic/Mohs surgery, otolaryngology, and plastic and reconstructive surgery were reviewed. Instructive images were compiled to illustrate several techniques, with additional medical illustration recreations included to help showcase important reconstructive approaches. RESULTS: A comprehensive descriptive review of nasal lining repair options for the reconstructive surgeon. CONCLUSION: Advanced tumors can result in full-thickness nasal defects, and this review describes various reconstructive options for reconstruction based on the extent of the defect.

BACKGROUND: Although current guidelines recommend a 5 mm surgical margin for the excision of melanoma in situ (MIS), increasing evidence has shown this may be suboptimal to achieve tumor clearance. OBJECTIVE: To evaluate margins required for optimal cure rates with excision of MIS on the head and neck and investigate tumor and/or patient factors in those requiring >5 mm margins to achieve tumor clearance. METHODS: A retrospective chart review was performed on 846 (807 primary and 39 recurrent) MIS cases on the head and neck treated in the authors' dermatologic surgery department over a 126-month (10.5 year) period. RESULTS: Sixty-two percent were cleared with 5 mm margins. A total of 15 mm margins were required to achieve a 97% clearance rate. Difference in clearance rate between margin thresholds was significant (P < .001). Tumor location on the cheek and larger preoperative size correlated with requiring >5 mm margins to achieve tumor clearance (P = .006 and P = .001, respectively). LIMITATIONS: This is a single-center retrospective study which relies on accurate documentation of clinical data. CONCLUSION: This study demonstrates that MIS on the head and neck often requires margins >5 mm margins to achieve tumor clearance. When Mohs micrographic surgery is not possible, excision margins of ≥10 mm are likely necessary for head and neck tumors.
