Abstract
Microtia with congenital aural stenosis requires multiple surgeries to obtain functional and apparent healing. However, meatoplasty for congenital aural stenosis can result in postoperative stenosis. A 38-year-old man was referred to our hospital for severe swelling behind the right auricle. He had microtia and congenital aural stenosis that had not been followed for a long time because of his serious mental retardation. He was diagnosed as having a huge external auditory canal （EAC） cholesteatoma that extended to the mastoid cavity. Due to the patient’s mental problem, re-stenosis of the EAC which would have required multiple surgeries needed to be avoided and therefore we planned to construct a new large EAC using a bone defect following mastoidectomy. After removal of the cholesteatoma by mastoidectomy, the original stenotic EAC was opened to the mastoid cavity. The orifice of the newly constructed EAC was covered by a superficial temporal fascia to prevent postoperative stenosis. There was no sign of cholesteatoma recurrence or postoperative stenosis of EAC for two years after the surgery. The pedicle flap such as for the superficial temporal fascia was a useful method to prevent the postoperative stenosis of EAC after meatoplasty.
