ABSTRACT

Objective To investigate therapeutic effect of bromhidrosis by botulinum toxin A injections and situation of bromhidrosis recurrence.Methods Clinical data of bromhidrosis patients were analyzed in our hospital from January 2013 to June 2014.A total of 89 cases were involved in this study and randomized into two groupsobservation group (42 cases) were treated by botulinum toxin A,and patients with the control group (47 cases) were treated by small skin excision.The total effective rate,incidence of complications and recurrence rate in both groups were compared.Results After treatment for 3 months,the total effective rate of both group had no statistical difference (P＞ 0.05).After different treatment,the incidence of complications in observation group of patients was 2.38％ (1/42),and that in the control group was 14.89％ (7/47);complication rates of control group patients was significantly higher than that of the observation group,with statistical significance (x2 =4.245,P＜0.05).After 9 months follow-up,31 cases in the observation group of patients showed bromidrosis recurrence,with recurrence rate of 73.81％;2 patients in the control group showed bromidrosis recurrence,with recurrence rate of 4.26％.Log-Rank test showed that recurrence rate in observation group was significantly higher than that of control group (x2 =43.21,P ＜0.05).Conclusions Botulinum toxin A injection is an uninvasive method for the treatment of bromhidrosis with fewer complications and good effect,but the postoperative recurrence rate is higher and it needs injections for many times.
