Partial Thickness vs Full Thickness Tragal Cartilage Grafts in Endoscopic Type 1 Tympanoplasty

Sponsor: Assiut University

Summary

Primary Objective: Compare 6-month graft success rates between 0.5 mm sliced and 1.8 mm full-thickness tragal cartilage grafts.(3) H1: Sliced cartilage yields ≥90% success versus ≤80% for full-thickness.(3) H0: No difference between arms. Secondary Objectives: * PTA-ABG closure at 6/12 months.(4) * Speech discrimination score improvement.(4) * Operative time.(6)
