The cartilage‐perichondrium graft in the treatment of posterior tympanic membrane retraction pockets

As the progress in modern ear surgery continues it is becoming apparent that the integrity of the scutum, the posterior‐superior canal wall annular rim and the bony chordal eminence play vital roles in the prevention of posterior tympanic membrane retraction pockets.1,2,3,4,5 A dehiscence of any or all of these structures, coincident with eustachian tube dysfunction and posterior tympanic membrane retraction, can lead to destruction of the incudo‐stapedial joint complex with or without cholesteatoma formation. Hearing loss is the most common sequala.
