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 < 1/3) A,57 specimens and group B (1/3 < or = pedicle/perimeter < 2/3), 63 specimens. In surgery without skin grafting group. The papilloma was excised by electrotome under microscope,external auditory canal was tamped with vaseline gauze for 1 week. In surgery with skin grafting group, we scratched the surface of the wound and got a retroauricular flap, sutured for 2-4 needles, external auditory canal was tamped with vaseline gauze for 2 weeks.
RESULT:In group A, the difference of two subunits has no statistical significance in epithelial change time, tumor recurrence, stricture of external auditory canal and cleaning function of external auditory canal (P > 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.
