ABSTRACT

OBJECTIVE@#To explore the indication of fixing defective epithelium with free skin flap after surgery treatment of papilloma of external auditory canal.@*METHOD@#One hundred and twenty patients suffered papilloma of external auditory canal and treated in our department was selected. The patients was divided into the surgery without skin grafting group and the surgery with skin grafting group according to their own options, surgery with skin grafting group was divided to group (pedicle/perimeter 0.05), indicating that it's not necessary to graft skin. In group B, the difference of two subunits had no statistical significance in tumor recurrence (P > 0.05), after skin-grafting, the epithelial change time reduced significantly (P < 0.05), there were 6 cases emerged stricture of external auditory canal and 8 cases emerged cleaning dysfunction of external auditory canal, had statistical significance between two subunits (P < 0.05).@*CONCLUSION@#Surgery with skin grafting should be choose when the tumor pedicle inhabits 1/3-2/3 of external auditory canal, it might improve the treatment effect significantly and reduce the complication.
