Abstract:
Objective To investigate the effect of tissue expansion in facial congenital giant nevus.Methods From October 2014 to October 2016,7 cases of facial congenital giant nevus patients were treated with expanded skin flaps,including single expansion and secondary expansion.Partial excision and skin tissue expansion were used to drastically remove giant pigmented nevi on body or extremities of infants.There were some points for attention during the surgery:the size and location of the partial excision and expander should be designed reasonably;no tumor-manipulation and non-tension principle should be taken great notice,and expanders should be linked up with one another when several expanders were used at the same time,so as to reduce the possibility of forming the envelop,which was favorable for the second surgery of transfer of a skin flap.Results All cases of giant pigmented nevi excision were on the face,which were completely removed from the patients.The areas of the nevi were from 7 cm × 5 cm to 15 cm × 13 cm.All patients were followed up for 3-12 months (mean 6 months).All flaps survived well.Expander exposure was happened in 2 cases with no bad results.One case of scar received late repair due to surgical scars and all got satisfactory results.Conclusions Tissue expansion is an ideal method in the treatment of facial congenital giant nevus.
