高频微针电灼仪治疗24例中重度腋臭患者临床研究

目的 评价使用高频微针电灼仪治疗腋臭的安全性及有效性.方法 收集2015年6月至2016年6月,北京协和医院皮肤科就诊的中重度腋臭患者24例,使用高频微针电灼仪(BodyTiteTM)进行单次治疗,治疗前后使用视觉-气味计分量表(VAS)评价腋下气味,生活质量SF-36量表评估健康相关生活质量,取患者腋下皮肤组织行病理学活检.结果 VAS量表评估显示,24例中22例达到并维持≥12周的症状缓解,平均气味评分下降率(VAS％)50％ ～ 100％,1例治疗后12周腋臭复发,1例未获得临床缓解.SF-36量表评估显示,治疗前患者在社会功能、情感职能、精神健康领域得分M(P0～P100)]分别为77.50(62.50～100.00)、66.67(33.30 ～ 100.00)、55.00(48.88 ～ 72.00),治疗后分别升至100.00(62.00 ～ 112.50)、100.00(33.30 ～ 110.00)、68.00 (48.00～ 80.00),治疗前后差异有统计学意义(均P＜ 0.05).组织病理显示,治疗后22例汗腺导管细胞出现明显变性、坏死,2例出现表皮损伤.安全性方面,1例治疗后出现单侧上肢疼痛,2例出现小面积皮肤烫伤样改变.术后平均恢复时间为7～ 14d.结论 高频微针电灼仪治疗腋臭临床有效率高,有良好的安全性,具有临床应用前景.

Fractional microneedle radiofrequency device for the treatment of 24 cases of moderate to severe axillary osmidrosis

Objective To evaluate safety and efficacy of a fractional microneedle radiofrequency device in the treatment of axillary osmidrosis.Methods A total of 24 patients with moderate to severe axillary osmidrosis were enrolled from Department of Dermatology of Peking Union Medical College Hospital between June 2015 and June 2016,and treated with the Body TiteTM fractional microneedle radiofrequency device for 1 session.Visual analogue scale (VAS) was used to evaluate the intensity of axillary odor in patients,36-item short-form health survey (SF-36) to assess health-related quality of life (HRQoL),and axillary skin tissues were resected for histopathological examination before and after the treatment.Results VAS showed that 22 of 24 patients achieved persistent remission for more than 12 weeks,and rates of decrease in odor score ranged from 50％ to 100％.However,1 patient experienced recurrence at 12 weeks after the treatment,and another 1 patient did not achieve clinical remission.SF-36 revealed that scores of social functioning (SF),role-emotional (RE) and mental health (MH) scales were all significantly increased after the treatment M (P0-P100):100.00 (62.00-112.50),100.00 (33.30-110.00),68.00 (48.00-80.00),respectively] compared with those before the treatment 77.50 (62.50-100.00),66.67 (33.30-100.00),55.00 (48.88-72.00),respectively,all P ＜ 0.05].Histopathological examination showed obvious degeneration and necrosis of sweat gland cells in 22 cases,and epidermal damages in 2 patients after the treatment.Unilateral upper-limb pain occurred in 1 case,and small-area burn-like skin changes were observed in 2 cases after the treatment.The postoperative recovery time ranged from 7 to 14 days.Conclusion The fractional microneedle radiofrequency device has shown high clinical response rate,good safety,and favorable application prospects in the treatment of axillary osmidrosis.
