Abstract:Objective To explore the clinical efficacy of ultra-micro 8.0 mm single-port thoracoscopic nerve resection through areola incision in the treatment of primary palmar hyperhidrosis (PPH).Methods 84 patients with PPH from January 2018 to January 2022, were divided into the observed group [(inframammary approach, IMA) group, n = 42] and control group [axillary approach (AA) group, n = 42]. The observed group was treated with ultra-micro 8.0 mm IMA single-port endoscopic thoracic sympathectomy (ETS), the control group used the traditional AA single-port ETS. The visual analogue scale (VAS) score, serum C-reactive protein (CRP), cortisol (Cor), interleukin-6 (IL-6) levels, the postoperative cosmetic effect and compensatory hyperhidrosis of the two groups were compared.Results The VAS scores of 2, 12 and 24 h after surgery in the observation group were significantly lower than those of the control group, the differences were statistically significant (P < 0.05); At 12 and 24 h postoperation, the levels of CPR, Cor, and IL-6 levels in both groups of patients were significantly higher than preoperation, but those in the observation group were significantly lower than those of the control group, the differences were statistically significant (P < 0.05); The total satisfaction rate of postoperative incision in the observation group was significantly higher than that of the control group, the difference was statistically significant (P < 0.05); There was no statistically significant difference of the incidence of compensatory hyperhidrosis between the two groups (P > 0.05).Conclusion The clinical efficacy of ultra-micro 8.0 mm IMA single-port ETS through areola incision in the treatment of PPH is good. Compared with the traditional axillary single-port thoracoscopic method, it has the advantages of small trauma, less bleeding, less patient pain, high safety and high patient satisfaction. It is worthy of clinical promotion and application.
