Hidden Blade Scalpel: A Useful Tool for the Treatment of Axillary Osmidrosis

Clinical Efficacy, Safety, and Complications of the Arthroscopic Cartilage Shaving Procedure for Secondary Osmidrosis Treatment

BACKGROUND

Axillary osmidrosis is a common disease with negative psychosocial impact on patients. Further, many treatment modalities are not sufficient and result in recurrence.

OBJECTIVE

We aimed to evaluate the effectiveness and safety of using a cartilage shaver in patients with recurrent osmidrosis to remove tightly attached apocrine glands and subdermal scars.

METHODS

We retrospectively evaluated 24 patients with secondary axillary osmidrosis who underwent cartilage shaving surgery between January 2013 and May 2022. We analyzed the incidence of complications, including seroma, infection, pigmentation, wound dehiscence, skin necrosis, scarring, shoulder movement limitation, comedones/sebaceous cysts, and nerve injury. Clinical effectiveness was also evaluated.

RESULTS

Excellent or good efficacy with improved malodor was achieved in 24 patients (47 axillae [100%]). Complications were observed in 16 (36.17%) axillae, including hematomas (n = 2), pigmentation (n = 7), skin necrosis (n = 3), and comedones/sebaceous cysts (n = 4); one patient (2.13%) required local debridement. Mean Vancouver Scar Scale scores were markedly low (5.41 to 4.67). Scar tissue did not interfere with the shaving surgery, allowing for successful removal of the apocrine glands.

CONCLUSIONS

Secondary osmidrosis treatment using a cartilage shaver system yielded satisfactory and better scar results than the patients' previous treatments.
