Eponychial marsupialization and nail removal for surgical treatment of chronic paronychia.

A long-term retrospective study of patients with chronic paronychia treated by eponychial marsupialization with or without nail removal is presented. Twenty-eight consecutive fingers with chronic paronychia in twenty-five patients were surgically treated. Symptoms had been present for 28 +/- 7 weeks. Twenty-three of these had nail irregularities. Of this group, the first seven fingers were treated with marsupialization alone. Recurrences developed in two of these. The next sixteen patients with nail irregularities were treated with marsupialization plus nail removal, and there were no recurrences (p less than 0.05). Furthermore, when the two recurrent paronychia were treated with both procedures, one healed completely and the other was markedly improved. All fingers without nail irregularities healed with marsupialization alone. These results confirm that eponychial marsupialization is an effective means of treating chronic paronychia and suggest that nail removal should be done when concurrent nail irregularities are seen.
