Management of Acquired Cholesteatoma Associated With Patulous Eustachian Tube and Habitual Sniffing

OBJECTIVES: To investigate the effect of surgical treatment with eustachian tube (ET) catheter insertion in patients with acquired cholesteatoma associated with patulous eustachian tube (PET) and habitual sniffing. METHODS: Nine ears of nine patients (two men and seven women; age, 20 to 65 years; average, 37.9±12.0 years) of acquired cholesteatoma associated with PET and habitual sniffing who underwent cholesteatoma surgery with simultaneous additional ET catheter insertion were examined in this study. Successful treatment was defined as stoppage of sniffing, a relief of a PET handicap inventory-10 (PHI-10), an improvement of autophony grade and no cholesteatoma recurrence. RESULTS: ET catheter insertion was performed in all ears. Follow-up duration ranged from 16 to 37 months (average, 25.4 months). Cases consisted of nine pars flaccida type (100%). All patients obtained relief from aural symptoms and stopped sniffing. Postoperative PHI-10 scores were significantly lower than preoperative scores (P<0.001). During an average follow-up of 25.4 months, no cholesteatoma recurrence has occurred to date. One patient developed otitis media with effusion (OME) post-catheterization; OME resolved spontaneously without treatment. Four patients had a consecutive ET catheter insertion on the other side to resolve PET-related aural symptoms. CONCLUSION: In case of acquired cholesteatoma with PET and habitual sniffing, ET catheter insertion performed simultaneously with cholesteatoma surgery could help reduce aural symptoms and stop sniffing. Moreover, the procedure might help in preventing cholesteatoma recurrence.
