Abstract

OBJECTIVE: To describe the clinical manifestations of external auditory canal (EAC) cholesteatoma and evaluate the surgical outcomes of reconstruction using an inferior pedicled soft-tissue periosteum flap.

 

MATERIALS and METHODS: A total of 28 patients were enrolled in this retrospective study conducted at Kaohsiung Medical University Hospital in Taiwan between January 2004 and December 2013. EAC cholesteatoma was classified according to the disease extent. The surgery was performed to reconstruct a smooth contour of EAC.

 

RESULTS: The average age of the 28 patients (9 males and 19 females: 30 surgical ears) was 53.7 years. The most common clinical manifestations were unilateral otalgia (63.3%) and otorrhea (46.7%), and the most frequent locations of EAC cholesteatoma with bony invasion were the posterior–inferior (40%), inferior (30%), posterior (20%), and posterior–inferior–anterior (10%) aspects. Based on Naim’s staging systems of EAC cholesteatoma, 26 ears (86.7%) were classified as stage III and 4 ears (13.3%) as stage IV. All patients received surgical management via a postauricular approach, and the average length of postoperative follow-up was 61.5 months (range 8–131 months). One patient had recurrence after surgery for 1 year 3 months.

 

CONCLUSION: Bony canaloplasty and obliteration with an inferior pedicled soft-tissue periosteum flap is a reliable procedure for EAC cholesteatoma.
