The effect of intense pulsed light for hair removal in pediatric auricular reconstruction
Objective To investigate the safety and efficiency of depilation with intense pulsed light(IPL)in congenital microtia patients during reconstruction treatment sessions.Methods A study was conducted at the Plastic and Reconstructive Surgery Hospital of Peking Union Medical College,Chinese Academy of Medical Sciences.From January 2018 to September 2021,a total of 96 patients were divided into two groups:the expansion group(58 cases)and the non-expansion group(38 cases),based on the treatment method.All pa-tients received 3 to 5 sessions of IPL treatment using filters ranging from 695 nm to 1200 nm,with a pulse width of 15 ms,single-pulse mode,and energy levels set at 14 to 15 J/cm2 for the non-expansion group and 13 to 14 J/cm2 for the expansion group.The efficacy of hair removal and the occurrence of adverse reactions were evaluated in both groups.Results All patients completed 3 treatments,while 75 patients completed 5 treatments.The reduction of hair density after 3 treatments is higher than the non-expansion group 82.28%(75.41%,88.54%)versus 76.53%(70.10%,85.34%),P<0.05.Among the patients who completed 3 treatments,44 in the expansion group and 21 in the non-expansion group achieved excellent treatment outcomes.After 5 treatments,44 patients in the expansion group and 31 pa-tients in the non-expansion group had excellent results.During the 6 to 11 months follow-up period,three cases of folliculitis and two cases of blisters were observed,none of which resulted in expander exposure or cartilage resorption.Conclusion Hair removal with IPL is a safe and effective photo-epilation method during all stages of ear reconstruction using tissue expander.
