OBJECTIVES: To standardize the information for families of children having functional surgery for middle ear malformations, we describe the audiometric results of the subgroup of patients with the most favorable anatomic conditions: viable auditory canal, intact tympanic membrane, mobile stapes, and corresponding to a Jahrsdoerfer score of 8 or higher. STUDY DESIGN: Case series, tertiary referral center. METHODS: Charts of patients undergoing functional surgery for congenital middle ear malformations were reviewed for demographic data, preoperative Jahrsdoerfer score, ossicular chain status, type of ossiculoplasty, and audiometric data before and 6 months postsurgery. RESULTS: Eighteen consecutive interventions were performed on 13 patients (average age of 9 years, 8 girls and 5 boys) between 2004 and 2011. The ossiculoplasties performed were as follows: incus repositioning (4), double-layer tragal cartilage (5), intact native chain reconstruction (3), and partial ossicular prosthesis (6). Mean air bone gap (ABG) was 40.8 ± 12.4 dB preoperatively and 20.9 ± 12.9 dB postoperatively (p < 0.0001). Preoperative and postoperatively mean air conduction PTA thresholds were 49.9 ± 9.5 and 30.0 ± 14.1 dB, respectively (p < 0.0001). All ears operated on except one had air conduction improvement. There were no complications. CONCLUSION: Functional surgery for congenital middle ear malformations gives variable hearing outcomes. In this study, with the most favorable anatomic conditions, 12 ears (67%) of 18 had air conduction improvement below 30 dB.
