Objective: The aim of this study was to present our experience on facing the dehiscent high jugular bulb (HJB) during middle ear surgery in the past two decades. Study Design: Retrospective review. Setting: Secondary referral hospital. Patients: From January 1982 to June 2002, consecutive 1 ,657 patients underwent surgical intervention for middle ear cleft diseases, total 1,857 operations. Of them, 10 ears (0. 5%) in 9 patients were proved as having dehiscent HJB during operation for adhesive otitis media in 4 ears, and chronic otitis media with cholesteatoma in 6 ears. Main Outcome Measures: Each patient underwent otoscopic examination, radiographic examination, and audiometry before and 6 months after operation. Results: Otoscopic examination revealed atrophic changes in the pars tensa with adhering to the promontory in 2 ears, attic retraction in 1 ear, and both findings in 7 ears. All lesions were located beneath the basal turn of the cochlea and the round window niche at anterior-inferior and/or posterior-inferior quadrants. Active bleeding was encountered in 2 ears (20%) while elevating the tympanomeatal flap, which was treated by pressure compression associated with gelfoam sheet, then covered with an autologous cartilage to protect the dehiscent bulb. For the remaining 8 ears, the bulbs were reinforced with fascia, perichondrium or autologous cartilage. All 10 ears were allowed completion of the planned surgery without complications. Conclusions: HJB is not a contraindication for middle ear surgery. Awareness of this pitfall may lessen the operation risk. |
