Abstract:
Objective To investigate the effect and safety of depilation with intense pulsed light ( IPL) in congenital microtia patients , and observe the impact factors of hair removal .Methods The hairy skin was treated with M22 system using a filter of 695 -1200 nm.Treatments were conducted using a contact probe with a window of 15 cm ×35 mm or 8 cm ×15 mm at a radiant exposures of 16-18 J/cm2 with three pulses(pulse duration:3.5 ms, delay duration:80 ms).Digital photograph was taken for the calculation of hair density with IPP software before treatments .Satisfaction index of hair removal ranked as follows:poor(percent reduction <25%), mild(25% -50%), good(50% -75%) and excellent ( >75%) .The hair removal effects was compared between different operation occasions ( skin expansion or non-skin expansion), and different ages(children or adults).Meanwhile, the side effects of IPL were observed.Results A total of 103 cases, aging from 6 to 24 years old with a median age of 9 years old, were included in our follow up project three months later after ear reconstruction .Seventy three cases initiated their hair removal during skin expansion period , and 29 cases initiated during non-expansion period.The reduction of hair density of one session treatment during skin expansion is much higher than that in non-skin expansion (32.4 ±7.1/cm2 vs 23.5 ±7.6/cm2, t=6.007,P=0).Children acchieved more satisfiedresult than those above 15 ages(χ2 =14.721, P=0.002).Instant pain was the main side effect, which was more profound in children with a rarely high pain score of 5.76 ±1.356.There were 4 cases of epifolliculitis , 3 cases of vesiculation .No expander exposure was found in this study .Conclusions Hair removal with intense pulsed light is a safe and effective photo-epilation during all the stages of ear reconstruction .The treatment initiated during skin expansion acchieved betterresult .The effect of hair removal with IPL in children is superior to adults .
