Context: Cartilage has proven to be an excellent graft material inside the middle ear. The use of cartilage for tympanic membrane grafting may provide additional benefits in some difficult situations. Aims: The study was planned to evaluate the graft uptake and hearing after placement of “boomerang-shaped chondroperichondrial graft” in Type I tympanoplasty. Settings and Design: The prospective study was conducted on 40 patients having chronic suppurative otitis media with no active disease at least for last 6 weeks in a tertiary care center of North India. Patients having cholesteatoma and ossicular erosion/or necrosis were excluded from the study.Subjects and Methods: Those patients underwent tympanoplasty Type I by postaural approach and underlay grafting using “boomerang-shaped chondroperichondrial graft” from tragal cartilage and were followed up for 3 months. Hearing evaluation was performed preoperatively and postoperatively after 3 months. Statistical Analysis Used: The mean, range, and standard deviation of air conduction and air-bone gap were calculated and compared with preoperative findings. Results: The mean age of study group was 26.23 ± 12.46 years. Ear discharge (100%) and hearing impairment (87.5%) were the chief presenting complaints. The mean duration of ear discharge was 6.67 ± 6.75 years. Type I tympanoplasty was performed in all cases using “boomerang-shaped chondroperichondrial graft” harvested from tragal cartilage. Graft was taken up at the 3rd month in all patients. The preoperative mean air conduction was 43.21 ± 7.17 dB, which at the 3rd month improved to 36.49 ± 6.60 (P = 0.00004). Preoperative mean air-bone gap was 25.45 ± 8.44 dB which was improved to 19.31 ± 8.18 dB postoperatively at the 3rd month (P = 0.0014). Conclusions: Boomerang-shaped chondroperichondrial graft has excellent “take rate” in Type I tympanoplasty.
