Tympanic Membrane Perforation, Otitis Media
Does Adding a Fascial Layer to the Cartilage in Tympanoplasty for Large Tympanic Membrane Perforation Affect the Overall Results?
Large tympanic membrane (eardrum) perforations present a surgical challenge and are historically associated with lower graft take rates compared to smaller perforations.
