To study the efficacy of interlay cartilage rim augmented fascia tympanoplasty in mucosal chronic otitis media. A retrospective, observational study was conducted in a tertiary care hospital including charts of patients spanning a duration of one year, where 15 patients diagnosed with chronic otitis media-mucosal disease with large and subtotal perforations (with or without ossicular erosion), and had undergone interlay cartilage rim augmented fascia tympanoplasty, were analysed for morphological and functional improvement following surgery. Pre- and post-operative otomicroscopic examination and pure tone audiometry findings were the parameters considered. 86.6% had a well-healed, non-retracted, undisplaced mobile neotympanum, 6.7% who underwent a type III (minor columella) tympanoplasty had a medialised neotympanum and 1 subject (6.7%) who underwent a type I tympanoplasty had a residual pinpoint perforation which healed with conservative management. The overall morphological success rate was 93.3%. The mean hearing gain following surgery was 20.84 dB with a minimum gain of 10 dB and a maximum gain of 30 dB. The mean air–bone gap closure gain achieved was 19.2 dB with a minimum gain of 6.4 dB and a maximum gain of 30 dB. The interlay cartilage-fascia rim augmentation tympanoplasty is a novel, effective graft model suggested for large and sub-total central perforations. Future randomized studies with a larger sample size could be performed with longer follow-up to assess the outcome of this technique.
