Five-Year Graft Outcomes and Complications of Endoscopic Cartilage–Perichondrium Sandwich Myringoplasty for Large Central Perforations

Five-year imaging follow-up demonstrated that endoscopic cartilage-perichondrium sandwich myringoplasty, performed without removal of the epithelium from the tympanic membrane remnant, achieved a stable graft success rate in the repair of large central perforations. The procedure was associated with a minimal risk of graft cholesteatoma and no observed risk of middle ear cholesteatoma.
