The tympanic membrane (eardrum) acts as a protective barrier between the middle and external ear, guarding the middle ear against infection. Additionally, it plays a crucial role in hearing by facilitating impedance matching between the air in the external canal and the fluid in the inner ear. Disruption of the tympanic membrane can lead to hearing loss, recurrent infections, and ear drainage. Common etiologies of perforations include infection and trauma. When perforations persist and cause symptomatic hearing loss or recurrent infections, surgical repair by an otolaryngologist becomes necessary. Although primary tympanoplasty has high success rates (75–95%), failures can complicate subsequent repair attempts. This case study presents a 61-year-old female who underwent two prior tympanoplasties without success. Dr. Cunningham demonstrates intraoperative decision-making and surgical techniques for repair in challenging cases.
