A Prospective, Long-Term Follow-Up Study of 1,444 nm Nd:YAG Laser: A New Modality for Treating Axillary Bromhidrosis

Background: Surgery for bromhidrosis has a high risk of complications such as hematoma and necrosis. New nonsurgical methods may reduce the burden on surgery and the risks for the patient. Objective: This study was performed to evaluate the efficacy and side-effects of the 1,444 nm Nd:YAG interstitial laser for treating axillary bromhidrosis. Methods: Eighteen bromhidrosis patients were treated with a 1,444 nm Nd:YAG laser at Korea University Ansan Hospital. The post-treatment follow-up was 6 months. After the procedure, we confirmed apocrine gland destruction through histopathological examination. At each follow-up, we measured the severity of the remaining odor, post- operative pain, degree of mobility restriction, and overall satisfaction. Results: After 180 days of follow-up, malodor elimination was good in 20 axillae, fair in 12 axillae, and poor in four axillae. At the end point of the study, 14 patients were totally satisfied with the laser treatment, three patients were partially satisfied, and one patient was disatisfied. Pain and limitation of mobility were significantly reduced within 1 week post-operatively, and were almost resolved within 4 weeks post-operatively. A histopathological examination revealed decreased density and significant alterations to the apocrine glands. Conclusion: Subdermal coagulation treatment with a 1,444 nm Nd:YAG interstitial laser may be a less Ann Dermatol invasive and effective therapy for axillary bromhidrosis.
