Abstract: Objective This study aimed to repair skin defects and enlarge the cavity of the external auditory canal with retroauricular pedicled flaps. Methods Sixteen patients with external auditory canal cholesteatoma and two patients with external auditory canal atresia were selected for this study. All surgical procedures were performed under general anesthesia through the retroauricular approach. Stenosis of the external auditory canal and annular granulation growth or atresia of the isthmus of the external auditory canal were observed during the operations. The bone canal of the external auditory canal was enlarged. Subsequently, the pedicled skin flap was removed at the retroauricular incision and transferred forward into the auditory canal to cover the skin defect of the posterior wall of the auditory canal and expand the cavity of the external auditory canal. Results The skin grafts of the auditory canal of all patients survived after the operation. The shape of the auditory canal of all patients recovered well 6 months after the operation, without stenosis or atresia. Conclusion The retroauricular pedicled skin flap is easy to obtain without new incisions. After skin grafting of the auditory canal, necrosis is unlikely to occur because of the blood supply to the skin grafts, which reduces the reoccurrence of auditory canal stenosis or atresia.

Key words: Pedicled flap, External auditory canal, Skin defect, Repair, Retroauricular approach
