Abstract
- Ossicular chain defects secondary to Chronic otitis media most frequently involves the incudo-stapedial joint. This study observes the effect of incudo-stapedial joint reconstruction using conchal cartilage interposition graft on hearing of the patient. Fifty-three patients with chronic otitis media of inactive mucosal type with incudostapedial necrosis of less than half of long process of incus were posted for tympanoplasty with incudostapedial joint reconstruction using autologus conchal cartilage. Their hearing outcome was analysed by comparing the pre-operative and 12 weeks post-operative Pure Tone Audiogram. A statistically significant improvement is seen in air conduction by 14.66 dB after incudo-stapedial joint reconstruction using conchal cartilage (p value 0.0001), whereas improvement seen in bone conduction was statistically insignificant. 52 (98.1%) patients had ≤ 40 dB post-op AC and 1 (1.9%) had > 40 dB.. Conchal cartilage is an easy-to-harvest, biocompatible and cost effective graft material. It gives hearing results comparable to other materials. [ABSTRACT FROM AUTHOR]
