Results of single stage ossicular reconstruction by incus transposition in patients with chronic otitis media.
Rawal Med J Nov ;32(2):179-82.

Objective: To evaluate outcome of single stage ossicular reconstruction in patients with chronic otitis media. Methods: We assessed thirty-three patients with chronic otitis media who underwent either tympanomastoidectomy or tympanoplasty together with ossicular reconstruction by incus transposition. All had audiotympanometry before and after operation. Air Bone Gap (ABG) and Speech Reception Threshold (SRT) were also calculated pre and postoperatively. Results: The mean preoperative ABG was 47.27±6.39 dB while mean postoperative ABG was 13.91±7.96 dB (p<0.05). The mean preoperative SRT was 58.06±6.60 dB while mean postoperative SRT was 24.27±7.78 dB (p<0.05). Postoperative ABG was less than 20 dB in 25 (75.8%) patients and it was more than 20 dB in 8 (24.2%) patients. Conclusions: Single stage ossicular reconstruction by incus transposition can lead to improvement of hearing levels of patients with chronic otitis media. Reconstructing the ossicular chain by incus transposition at the time of middle ear surgery has an important role in reducing patients` hospitalization and related costs.
