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. The purpose of this paper is to describe the cartilage‐perichondrium graft repair of the posterior‐superior canal wall bony structures, as developed by the late Dr. Frederick Guilford, and to discuss the associated treatment of posterior tympanic membrane retraction pockets. The cartilage‐perichondrium graft is obtained at surgery from the posterior conchal region. The cartilage is fashioned to fit the dehiscent bone in the posterior‐superior canal wall segment. The perichondrium supports the cartilage and is used to repair any tympanic membrane perforation. Ten cases are presented in which the cartilage‐perichondrium graft was used. No posterior tympanic membrane retraction pockets were noted in follow‐up of these cases.
