5. The Role of Cartilage-perichondrium Tympanoplasty in the Treatment of Tympanic Membrane Retractions: Systematic Review of the Literature
Abstract Introduction Tympanic retraction is a condition characterized by the displacement of the tympanic membrane toward the structures of the middle ear. Clinically, tympanic retractions can lead to hearing loss, ear discharge and/or ear pain. In most of the cases, however, tympanic retractions are asymptomatic and are found accidentally during an ear, n
