Refining Nail Surgery: Clinical Pearls and Best Practices

Abstract

The nail is not only aesthetically significant but also functionally essential, as it protects the distal digits and serves as a counterpart for pressure-bearing areas. Nail surgery presents unique challenges since, even after successful treatment of pathological conditions, scarring may lead to cosmetic deformities, and partial or complete nail loss can result in functional impairment. Fortunately, recent advancements in nail surgery have improved treatment success rates while minimizing complications. This review focuses on the surgical management of 6 key nail disorders: ingrowing nails, pincer nails, onychogryphosis, glomus tumors, digital mucous cysts (DMCs), and nail unit melanoma (NUM). For recalcitrant ingrowing nails, soft tissue excision rather than direct nail intervention yields better outcomes. Pincer nails require surgical correction of the protruding nail bed to prevent recurrence. Onychogryphosis is effectively managed with repeated nail grinding to reduce thickness and maintain nail shape. Glomus tumors can be effectively diagnosed using ultrasound, with surgical excision reserved for cases with clear imaging findings. DMCs may be treated with surgical deroofing followed by chemical peeling agents to reduce recurrence. In NUM, a conservative surgical approach can be considered for cases of in situ or minimally invasive, avoiding unnecessary amputation. This review synthesizes key clinical pearls and best practices to optimize patient outcomes in nail surgery. By integrating the latest evidence and surgical innovations, we provide a comprehensive guide for dermatologic and surgical practitioners seeking to refine their approach to nail procedures.
