Chronic axillary hidradenitis--the efficacy of wide excision and flap coverage.

A number of different modalities of surgical treatment for axillary hidradenitis suppurativa have been suggested. This study compares three different methods of surgical excision. Fifty-nine patients (94 axillae) were treated over a 14-year period. There were 42 females and 17 males with an average age of 32 years (range 16-65 years). Twenty-six axillae had excision of only the diseased skin and recurrent disease occurred in seven. However, in 39 axillae that were treated by excision of all the hair bearing skin, only three developed recurrent disease, which is a significant reduction in the incidence of recurrent disease (P = 0.04, Fischer's exact test). Twenty-nine axillae were treated by wide local excision (2 cm beyond the hair bearing skin) and no recurrence occurred. However, there was no statistical difference (P = 0.18, Fischer's exact test) in disease recurrence between excision of all the hair bearing skin and wide local excision. This study suggests that excision of all the hair bearing skin is the preferred method of surgical treatment. Flap coverage was an effective method to achieve wound closure after adequate excision and can be achieved by random fasciocutaneous flaps for small or medium sized defects and parascapular flaps for large defects.
