Popis: | Objectives Conventional reporting of postoperative hearing outcomes utilizes a pure‐tone averaged air‐bone gap (ABG) that is biased toward low frequencies. Consequently, a high‐frequency ABG after otologic surgery may go unnoticed. In this study, we evaluate changes in low‐ and high‐frequency ABG following ossiculoplasty. Study design Retrospective review. Subjects and setting Consecutive series of patients who underwent ossiculoplasty at a single tertiary care center. Patients with pre‐ and postoperative audiograms were included. Methods Low‐frequency ABG was calculated as the mean ABG at 250, 500, and 1000 Hz. High‐frequency ABG was calculated at 4 kHz. Pre‐ and postoperative ABGs were compared. Results Thirty‐seven consecutive patients were included. Mean age at surgery was 38 years (range, 7‐77 years). Reconstruction materials included: cartilage (N = 4), hydroxyapatite cement (N = 5), and partial or total ossicular replacement prostheses (N = 20 and N = 8, respectively). Postoperatively, the mean low‐frequency ABG improved by 11.9 ± 15.1 dB (P |
