En Bloc Excision of Proximal Nail Fold for Treatment of Chronic Paronychia

BACKGROUND: Chronic paronychia is a very recalcitrant dermatosis, which is particularly prevalent in housewives. Medical treatment for this condition is unsatisfactory in a significant number of cases. Surgical approach forms an important part of management, however, this area has received little attention. Various surgical approaches have been tried in the past but a comparative analysis has not been attempted. OBJECTIVES: The present study aims at assessing the efficacy of en bloc excision of proximal nail fold (PNF). Moreover, a comparative analysis has been undertaken to assess whether or not simultaneous nail plate avulsion improves the treatment outcome. METHODS: Thirty patients of chronic paronychia with nail plate irregularities were randomly divided into two treatment groups (15 patients each). After a detailed evaluation, en bloc excision of PNF with or without nail plate removal was performed. Postoperative measures were advised and the patients were kept under regular follow-up thereafter. Assessment of postoperative complications was also performed. RESULTS: Twelve patients in group I and 13 patients in group II completed the treatment protocol. Of these, 70% of patients were cured in group II (en bloc excision with nail avulsion) whereas only 41% were cured in group I (en bloc excision without nail avulsion). CONCLUSION: En bloc excision of the PNF is a useful method in recalcitrant chronic paronychia. Simultaneous avulsion of the nail plate improves the surgical outcome. Strict avoidance of irritant exposure is necessary to ensure complete treatment and prevent recurrence.
