OBJECTIVE: To determine the most common indications for revision congenital aural atresia (CAA) surgery and the postoperative healing and hearing outcomes of revision surgery.
STUDY DESIGN: Retrospective case review.
SETTING: Tertiary care academic otologic practice.
PATIENTS: Patients undergoing revision surgery for CAA.
INTERVENTION: Revision surgery for CAA.
MAIN OUTCOME MEASURES: Indications for revision atresiaplasty, time to revision surgery, postoperative external auditory canal (EAC) patency, incidence of chronic drainage and/or infection, and postoperative speech reception thresholds (SRTs), and air-bone gaps.
RESULTS: Indications for 75 ears (69 patients) undergoing 107 revision operations for CAA included 58% for EAC stenosis, 19% for chronic drainage and/or infection, and 20% for conductive hearing loss (CHL) alone. Fifty ears (67%) required a single revision. Twenty-five ears (33%) required more than 1 revision. With follow-up longer than 3 months (mean, 41 mo), 69% of ears revised for EAC stenosis achieved a patent canal (29% required >1 revision); 75% of ears revised for chronic drainage and/or infection (mean follow-up, 53 mo) realized a dry canal (22% required >1 revision). For all revision surgeries with adequate follow-up (n = 80), the mean postoperative short-term SRT of 24 dB HL was a significant improvement from the mean preoperative SRT of 39 dB HL (p < 0.01, paired t test).
CONCLUSION: EAC stenosis is the most common indication for revision atresiaplasty. Despite the challenges of revision surgery, improvement in canal patency, epithelialization, and hearing utcomes can be achieved.
