Comparison of Results of Myringoplasty with Temporalis Fascia and Perichondrial: Cartilage Composite Graft in High Risk Perforations

Background: The objectives of this study were to compare the graft uptake and post-operative hearing results underlay myringoplasty with temporalis fascia perichondrial-cartilage composite in high risk perforations. Materials & Methods: Patients ages 13 years above diagnosis chronic otitis media – mucosal type perforations undergoing included. Criteria >50% perforation tympanic membrane, revision cases, absent/eroded handle malleus, oedematous/unhealthy middle ear mucosa marginal any size. Pure tone audiometry was done within 1 week before surgery. Seventy cases included for randomly allocated by lottery method into two groups 35 each group perichondrial - cartilage group. After 6 weeks assessed evaluated compared between groups. Results: Graft rates perichodrial 88.57% 91.43%, respectively no statistically significant difference (p = 0.69). mean pre- air bone gaps 31.81 ± 10.49 dB 17.87 7.96 dB. 35.19 ±7.26 22.62 8.77 These differences both highly < 0.001) showing improvement after ABG gains 13.94 8.36 12.57 8.21 respectively. Conclusion: are similar those graft. Perichondrial- even though more rigid thicker than did not affect adversely
