Background: Pincer nail deformity (PND) is a common toenail disorder characterized by transverse over-curvature of the nail plate. It can cause severe pain, chronic inflammation, and recurrent infections. Both conservative and surgical treatment options carry different disadvantages of limited efficacy, high recurrence rate, and poor cosmetic outcome. The study aimed to evaluate the safety and effectiveness of carbon dioxide (CO2) laser matricectomy for the treatment of PND. Methods: The database of the laser unit of a tertiary medical center was retrospectively searched for all patients who were diagnosed with PND in 2016–2022 and treated with lateral and/or medial matricectomy using CO2 laser. Clinical and follow-up data were collected from the medical files. Results:The cohort included 19 patients (5 male, 14 female) who underwent 25 partial matricectomies during the study period (some patients had more than one diseased nail). All procedures were successful, with no intraoperative or postoperative complications. There was one documented recurrence at 7 months after treatment. Conclusion: Partial CO2 laser matricectomy is safe and effective for the treatment of PND.
