Abstract：Objective To investigate the therapeutic and aesthetics effects of ultrasound-guided local puncture on congenital preauricular fistula infection ( CPFI) . Methods A total of 110 patients with CPFI from January 2010 to January 2015 were randomly divided into control group ( n=55 ) and observation group ( n=55 ) by means of randomized stratified method. The patients in control group were treated by traditional incision and drainage,however,the patients in observation group were treated by ultrasound-guided local puncture and irrigation combined with microwave therapeutic apparatus. After treatment the abscess cavity healing time,pain disappearance time and incidence rate of adverse reactions were observed and compared between two grousp. Moreover,the patients in both groups were followed up for 1 year,and the recurrence status, scar length and the aesthetic satisfaction rate were observed and compared between two grousp. Results The abscess cavity healing time,pain disappearance time and cure time in observation group were significantly shorter than those in control group (P<0. 05). No severe complications were observed in both groups during treatment,and there were no significant differences between two groups (P>0. 05). The 1-year recurrence rate (1. 8％) in observation group was significantly lower than that (12.7％) in control group (P <0. 05). Moreover there were significant differences in total satisfaction rate (70. 9％ vs 87.3％) and scar length [(1. 59 ± 0. 12)、(0. 48 ± 0. 13)cm] between the two groups (P <0. 05). Conclusion The ultrasound-guided puncture in treatment of congenital ear fistula infection can obtain obvious therapeutic effects, with less trauma,shorter treatment course,lower recurrence rate,which can reduce the scar formation,maintain the facial beauty so as to achieve more satisfactory aesthetic effects,therefor,which is worthy of clinical promotion.
