Comparative efficacy of matrix phenolization and nail bed reconstruction for pincer nail deformity: a retrospective study.

Abstract

Objective: To compare the efficacy and safety of matrix phenolization and nail bed reconstruction for pincer nail deformity (PND).

Methods: This study included 34 patients with 37 nails divided into matrix phenolization group (n = 21) and nail bed reconstruction group (n = 16). The width index, height index, curvature index of nail plate and visual analog scale (VAS) of pain were recorded preoperatively, 6 and 12 months postoperatively. Early postoperative pain, treatment effect, postoperative complications and patient satisfaction were also recorded.

Results: The width index was higher, and the height index, curvature index, and VAS were lower at 6 and 12 months after both surgeries (p < 0.05). At 6 months after surgery, the height index and curvature index of nail bed reconstruction were lower than matrix phenolization (p < 0.05). There was no significant difference in the width index and VAS between two groups. At 12 months after surgery, there was no significant difference in the width index, height index, curvature index and VAS between two groups. Two cases had recurrence after matrix phenolization and two cases had nail fold pain after nail bed reconstruction. All patients were satisfied.

Conclusion: Matrix phenolization and nail bed reconstruction both showed good efficacy and safety in the treatment of PND. Matrix phenolization has simple operation, mild pain and fast postoperative recovery, which is recommended in clinical practice.
