Reconstruction of microtia with laser hair removal before transplantation of costal cartilage.
When scalp skin is contained in reconstruction of microtia, the hair growth on the reconstructed auricle causes aesthetic problems. Several techniques to deal with hairline, such as skin graft, skin flap, tissue expander and electroepilation, have been reported, but there are few reports using laser hair removal for microtia patients. We performed presurgical laser therapy in five patients. The low regions of hairlines in unilateral microtia children were irradiated by two kinds of laser systems for 1 year before the transplantation of costal cartilage. When hair growth was seen after the surgery, laser irradiations were performed. Video-microscopic and histological studies were examined to check the rates of epilation and skin injuries. There were no conspicuous hairs on the reconstructed ears and no side effects such as skin injury, folliculitis and deformity of cartilage. Video-microscopic examination revealed that terminal hair was rarely observed after irradiation, although the amount of vellus hair after irradiation was the same as that before irradiation. Histological examination showed that atrophy or hyperplasia of epidermis and dermis were not observed. Although patients had to undergo laser epilation from four to seven times because of a hair cycle, the laser epilation is less invasive and safer than other surgical procedures to reconstruct non-haired helix.
