Factors Affecting the Efficacy of Suction Curettage Using an Arthroscopic Shaver for Bromhidrosis

BACKGROUND Suction-curettage using an arthroscopic shaver is the most effective surgical treatment for bromhidrosis; however, information regarding the procedure is limited. This study investigated the factors that affect the efficacy of suction-curettage. PATIENTS AND METHODS We retrospectively evaluated data for 215 patients (430 axillae) with bromhidrosis treated with suction-curettage using an arthroscopic shaver between 2011 and 2019. RESULTS Excellent or good efficacy with improved malodor was achieved in 418 axillae (97.21%). Secondary suction-curettage was performed for 11 (2.56%), with excellent results. Efficacy and need for secondary suction-curettage were not associated with age, sex, shaving time, and tumescent infiltration use. Complications were observed in 52 (12.09%) axillae, including hematoma or seroma, epidermis decortication, skin necrosis, and infections; 10 (2.33%) required local debridement for wounds. Complications showed a significant difference with respect to age ( p < .001). Pain scores on postoperative Day 2 were significantly lower for patients treated using tumescent infiltration than those for the others (1.65 ± 0.84 vs 4.57 ± 1.16; p < .001). CONCLUSION The results suggest that 7 to 15 minutes of suction curettage using an arthroscopic shaver is sufficient to achieve good efficacy for bromhidrosis with few complications. Older age was a risk factor for complications, and tumescent infiltration use achieved good postoperative pain control. Levels of Evidence II.
