OBJECTIVE: To assess the association of middle ear volume with long-term hearing outcomes in congenital aural atresia (CAA) repair.
STUDY DESIGN: Retrospective chart and radiological review.
SETTING: Single academic tertiary referral center.
PATIENTS: Children and adults who underwent CAA repair between 1995 and 2016. Patients were divided into "best" and "worst" audiometric groups, based on stability of postoperative air conduction pure-tone average (AC PTA) results. Ten patients were included for study in the "best" group, and 12 in the "worst" group.
INTERVENTION(S): CAA repair.
MAIN OUTCOME MEASURE(S): Long-term (> 1 yr) postoperative three-tone (500, 1000, 2000 Hz) AC PTA, speech reception threshold (SRT), air bone gap, and semiautomated calculated middle ear volume from preoperative computed tomography (CT) scans.
RESULTS: Statistically significant differences were noted between "best" and "worst" groups in AC PTA, SRT, and air bone gap (p < 0.001). Mean middle ear volume in the "best" group was 434.6 mm (range 326.3-602.1 mm) and 339.5 mm (range 199.4-502.1 mm) in the "worst" group (p = 0.02). The majority in both groups were right ears (p = 0.38), and males outnumbered females in the "best" group (9 out of 10; p = 0.018). Preoperative Jahrsdoerfer grading scores were similar between groups (p = 0.31). Mean follow-up for the "best" and "worst" groups was approximately 3.5 and 4.5 yr, respectively.
CONCLUSIONS: For patients undergoing CAA repair, larger middle ear volume is associated with stable and better long-term audiometric outcomes.
