Liposuction-assisted circumferential trimming in treatment of axillary osmidrosis (AO)

<b>Background:</b> The study is to investigate the effectiveness and safety of the minimally invasive treatment for axillary osmidrosis by liposuction assisted circumferential trimming. <b>Methods:</b> It was a retrospective study. From July 2014 to July 2017, 79 patients underwent superficial liposuction and circumferential trimming for bilateral axillary osmidrosis. The preoperative and postoperative degree of axillary malodor was measured by doctors and the patients themselves. In the doctor’s evaluation, the odor levels were scored by the sniffing method before and 1 year after treatment. In the patient’s self-assessment, each patient selected a scale value to convey his/her satisfaction during the visits after 1 year. The complications were recorded. <b>Results:</b> The follow-up period ranged from 12 to 24 months after surgery, and the mean follow-up period was 16 months. 75 (94.9%) had good results, four (5.1%) had moderate malodor or recurrence after one year. When considering patient’s own satisfaction, 93.7% (74/79) of patients were satisfied with the outcomes after one year. The partial epidermis necrosis was observed in four patients, it healed spontaneously without scarring. Three patients had a small amount of hematoma which was easily evacuated through the central primary incision. There was no other serious side effect. <b>Conclusions:</b> The liposuction assisted circumferential trimming technique is proved reliable and safe in treatment for axillary osmidrosis.

<b>背景：</b>本研究旨在探讨吸脂辅助环形修剪术治疗腋臭（axillary osmidrosis）的有效性与安全性。<b>方法：</b>本研究为回顾性研究。2014年7月至2017年7月期间，共79例双侧腋臭患者接受了浅层吸脂联合环形修剪术治疗。由医师及患者本人分别于术前及术后评估腋臭程度。医师评估采用嗅探法对治疗前及治疗1年后的异味程度进行评分；患者自评则于术后1年的随访中，通过选择量表分值表达自身对治疗效果的满意度。同时记录术后并发症发生情况。<b>结果：</b>术后随访时长为12至24个月，平均随访时长16个月。75例（94.9%）患者治疗效果优良，4例（5.1%）患者术后1年仍存在中度异味或出现复发。就患者自身满意度而言，93.7%（74/79）的患者对术后1年的治疗效果表示满意。4例患者出现局部表皮坏死，均自行愈合且未遗留瘢痕；3例患者出现少量血肿，可通过原切口中央位置轻松引流清除。未出现其他严重不良反应。<b>结论：</b>吸脂辅助环形修剪术治疗腋臭的方案被证实可靠且安全。
