Posterior tragal perichondrium harvesting for myringoplasty.
We present a modified harvesting approach for tragal perichondrium, used in tympanic membrane reconstruction. The technique described avoids amputation of the targus thereby facilitating dissection of the perichondrium from the cartilage as compared to the traditional method. The approach described is technically easier, and removes any potential for cosmetic deformity associated with tragal cartilage amputation and reimplantation. Furthermore, both the anterior tragal perichondrium and the temporalis fascia remain intact if further surgery is required. We recommend this approach for permeatal, tragal perichondrial grafting of small to medium sized tympanic membrane perforations.
