Endoscopic Transcanal Simple Myringoplasty Using Push Through Technique with Cartilage Ring Graft Versus Temporalis Fascia Graft

Objective: Assessment of endoscopic transcanal simple myringoplasty using a push-through technique with cartilage ring graft versus temporalis fascia graft. Patients and Methods: A prospective comparative study was conducted on 60 patients distributed randomly and equally into two groups. Both groups were subjected to endoscopic transcanal simple myringoplasty using a push-through technique with cartilage ring graft used in group I and temporalis fascia graft used in group II. The degree of improvement of postoperative air-bone gap (ABG) was assessed in both groups. Both groups were compared regarding healing, hearing success, and ABG gain. The correlation between the healing success and size and site of the perforation was assessed. Results: The present study showed a highly significant ABG improvement in both groups (p< 0.00001 for both). There was a non-significant difference between the two groups regarding healing success (83.3% and 80% respectively), hearing success, and ABG gain (p = 0.739, 0.417, and 0.757 respectively). There was a non-significant correlation between the healing success in both groups and the perforation size (p = 0.6221 and 0.3598, respectively). There was a non-significant correlation between the healing success of the operation in both groups and the perforation site (p = 0.704 and 0.516, respectively). Conclusion: Both cartilage ring and temporalis fascia grafts resulted in a highly significant postoperative improvement of ABG with comparable results regarding healing and hearing success and ABG gain. Both graft types showed a nonsignificant correlation between success and site and size of the perforation.
