An Objective Assessment of Long-term Postoperative Hyperpigmentation in Patients With Apocrine Gland-eliminated Osmidrosis Surgery.

Background: Radical surgery is the best treatment for axillary osmidrosis to eliminate the apocrine glands. However, marked postoperative hyperpigmentation may occur. Clinicians need an objective skin pigmentation examination to identify and treat hyperpigmentation. In this study, we aimed to use the Taylor Hyperpigmentation Scale (an objective visual scale) for evaluating long-term hyperpigmentation after osmidrosis surgery. Methods: Twenty female patients with Fitzpatrick skin type III-IV who had undergone osmidrosis surgery were included in this study. Results: The findings demonstrated that although there is an initial variation in the intensity of hyperpigmentation, in the majority of patients, there is a peak in hyperpigmentation between the third and sixth months after surgery. This is then followed by a gradual decline over the ensuing months. Some patients resolve hyperpigmentation completely, suggesting reversibility. Conclusions: These results can help guide patient expectations and provide suitable postoperative management, thereby improving patient satisfaction and overall quality of life.
