Background: Nail matrix histopathologic examination is still the criterion standard to diagnose longitudinal melanonychia (LM).
Objective: To introduce modified shave surgery combined with the nail window technique for managing LM and evaluate the postoperative outcome of the procedure.
Methods: We retrospectively reviewed the medical records of 67 patients with LM who underwent shave surgery combined with the longitudinal-strip nail window technique at our institution from March 2015 to June 2018.
Results: Pathologic diagnosis was accessible in all cases, and 60 cases were assessable for the postoperative outcomes. A total of 45 cases (75.0%) had no postoperative nail dystrophy, and recurrence of nail pigmentation was found in only 8 cases (13.3%).
Limitations: This was a retrospective study.
Conclusion: Modified shave surgery combined with the nail window technique is the preferable management for LM cases, with limited postoperative nail dystrophy and recurrence of pigmentation.
