Minimally invasive approaches to axillary osmidrosis treatment: A comparison between superficial liposuction with automatic shaver curettage, subcutaneous laser treatment, and microwave-based therapy with a modified technique.

BACKGROUND

Minimally invasive techniques, including superficial liposuction with automatic shaver curettage (LC), subcutaneous laser treatment, and microwave-based therapy have been developed to treat osmidrosis. Few studies have compared these three techniques in relation to clinical efficacy, life quality improvement, and downtime.

AIMS: We aim to evaluate clinical results and life quality improvement, in addition to downtime and complications, between these three techniques.

PATIENTS/

METHODS

Clinical records of patients treated with these three minimally invasive techniques for axillary osmidrosis were retrospectively reviewed. Hyperhidrosis disease severity scale, Dermatology Life of Quality Index, clinical improvement, complication, and recurrence were assessed.

RESULTS

Among 403 patients, 168 received microwave-based therapy, 119 received subcutaneous laser treatment, and 116 received LC. All treatments showed significant improvements (P < 0.001) in HDSS, DLQI and clinical result after 3 and 12 months comparing to the baseline. But the improvements of subcutaneous laser were significantly inferior to microwave-base therapy and LC. Patients who received LC had a significantly longer downtime (P < 0.001) than those who received other treatments. The recurrence rate was significantly higher in the subcutaneous laser treatment group, and the microwave-based therapy group exhibited a longer recurrence duration (P < 0.001). LC group presented higher complication rate than other treatments.

CONCLUSION

Comparing to other treatments, microwave-based therapy was effective in treating osmidrosis with minimal downtime, recurrence, and complications. It could be a durable and effective therapeutic modality for osmidrosis and is less operator-dependent. It may be considered as a first-line treatment for axillary osmidrosis.
