Background: Axillary osmidrosis is a distressing problem caused by hyperactivity of apocrine glands. There have been numerous studies on various surgical treatment methods. In this study, we evaluated the effectiveness of en bloc excision in comparison with dermal shaving.
Methods: The electronic records of 146 patients (286 axillae) who underwent surgery at our center for axillary osmidrosis between January 2009 and December 2020 were reviewed. Twenty-five patients (49 axillae) underwent en bloc excision and 121 (237 axillae) underwent dermal shaving. Patients in the en bloc excision group underwent Minor test preoperatively to detect sweating areas. Severity of osmidrosis was graded using a 4-point scale (0-3). A satisfaction questionnaire was used to evaluate patient experiences in the 2 types.
Results: Mean operation time was significantly shorter in the en bloc excision group than in dermal shaving group. Most en bloc excisions were performed on an outpatient basis under local anesthesia. Both groups showed an improvement in osmidrosis score at 6 months after surgery. A satisfaction questionnaire revealed better perioperative experiences in the en bloc excision group. Various surgical complications such as hematoma, wound dehiscence, and flap necrosis occurred in the dermal shaving group, and the en bloc excision group experienced significantly fewer complications that required intervention.
Conclusions: En bloc excision combined with Minor test effectively reduces malodor without causing severe complications. In addition, perioperative patient satisfaction was better in the en bloc excision group than in the dermal shaving group as en bloc excision provided more rapid returns to normality and simplified communications with patients.
