Few publications have addressed nasal valve (NV) insufficiency as a complication of Mohs micrographic surgery.
To comprehensively review the literature and further characterize the causes, prevalence, evaluation, and management of NV insufficiency as it relates to cutaneous oncology.
A PubMed search was completed to identify articles related to the NV in the context of Mohs micrographic surgery, cutaneous oncology, and reconstruction.
Nasal valve insufficiency may occur during tumor removal and/or reconstruction. Defect size larger than 1 cm; location on the ala, sidewall, or alar crease; lack of structural support; and poorly planned flaps are the main risk factors for NV insufficiency. Several surgical techniques have been described to avoid and correct this complication.
Nasal valve insufficiency may be an underrecognized and underreported complication of Mohs micrographic surgery. Nasal valve insufficiency may be identified with relatively simple tests. Knowledge of NV anatomy and preoperative function assessment is essential. Recognition of this potential complication and awareness of its prevention and management may decrease morbidity in patients undergoing cutaneous surgery.
很少有出版物涉及鼻阀（NV）不足作为 Mohs 显微外科手术的并发症。
全面复习文献，进一步描述 NV 不足的原因、患病率、评估和管理，以及其与皮肤肿瘤学的关系。
通过 PubMed 搜索，确定了与 Mohs 显微外科手术、皮肤肿瘤学和重建中 NV 相关的文章。
鼻阀不足可能发生在肿瘤切除和/或重建过程中。缺陷大小大于 1 厘米；位于鼻翼、侧壁或鼻翼皱襞；缺乏结构支撑；以及计划不佳的皮瓣是 NV 不足的主要危险因素。已经描述了几种手术技术来避免和纠正这种并发症。
鼻阀不足可能是 Mohs 显微外科手术中一个被低估和漏报的并发症。鼻阀不足可以通过相对简单的测试来识别。了解 NV 解剖结构和术前功能评估至关重要。认识到这种潜在的并发症，并意识到其预防和管理，可以降低接受皮肤手术患者的发病率。
