Histopathological Evidence of the Efficacy of Percutaneous Ethanol Injection in the Treatment of Axillary Osmidrosis: A Promising New Procedure

Clinical efficacy of microwave in the treatment of axillary osmidrosis and primary hyperhidrosis

BACKGROUND

Axillary osmidrosis(AO) and primary hyperhidrosis(PH) are common diseases, but there are still difficulties in treatment. Microwave therapy may become a new method.

OBJECTIVE

To evaluate long-time efficacy of patients with AO or PH treated by microwave. To discuss possible mechanism of microwave therapy by combining results of clinical and pathological.

METHODS

Ten AO or PH patients with moderate or severe level were selected as subjects, and each subject received microwave treatment of bilateral armpits. The follow-up period lasted two years,and the changes of perspiration and odor were evaluated in subjective and objective ways. Each subject took skin biopsy in the treatment area before and after treatment or each follow-up. HE and immunohistochemical staining were performed.

RESULTS

Both subjective and objective index reflected the significant improvement of AO and PH after treatment(P<0.05). Dermatology life quality index score decreased by 10.4±4.6(P<0.05). The number of apocrine glands decreased significantly after treatment, and most of them changed from secretory phase to quiescent phase.

CONCLUSIONS

Microwave therapy can destroy apocrine sweat glands, reduce number of functional glands, so as to improve symptoms of AO and PH and elevate quality of life, which is safe, effective and stable. This article is protected by copyright. All rights reserved.
