Impact of cartilage graft size on success of tympanoplasty

Abstract

Size of a cartilage graft has no impact on degree of hearing improvement or anatomical success rate after tympanoplasty.

Impact of type of graft material on outcome of tympanoplasty: a comparison between temporalis fascia and cartilage with perichondrium

“…For optimal acoustic transfer behavior, the cartilage should be cut as thin as possible. 13,14 Cartilage slices <0.5 mm thickness is similar to the tympanic membrane in their acoustic properties. In a normally ventilated middle ear, a cartilage plate of thickness <0.5 mm possesses sufficient mechanical stability and low acoustic transfer loss.…”

The Outcome of Endoscopic Assisted Underlay Tragal Cartilage Myringoplasty

“…Temporalis fascia graft: The anterior or posterior sectors perforations were restricted to one sector with normal tubaric function tests, with or without retractions of the pars tensa. (5) III. Other grafting materials have also been used, including loose areolar tissue, vein, and fat.…”

“…(4) The main advantages of cartilage are its stiffness and extremely low metabolic requirements, making it particularly suitable for adverse conditions such as partial perforations, adhesive otitis media, and reoperations. (5) Cartilage may be harvested with its attached perichondrium from the tragus or the concha. Tragal cartilage is thicker and flatter than conchalcartilage, and it may be more suitable for larger perforations.…”

Comparing audiometric parameters between crushed and intact cartilage tympanoplasty: a double-blinded, randomised, controlled trial study

“…These features mean the graft can be used for reconstruction in subtotal perforation, adhesive otitis and revision tympanoplasty. 8–12 In cartilage tympanoplasty, the stiffness and bulk of the cartilage may affect the transmission of the sound through the ear; hence, it may have some effect on hearing. 13–15…”

[8][9][10][11][12] In cartilage tympanoplasty, the stiffness and bulk of the cartilage may affect the transmission of the sound through the ear; hence, it may have some effect on hearing. [13][14][15] Crushed human auricular and costal cartilage grafts have been used in other procedures such as rhinoplasty to facilitate resorption and the reduction of chondrocytes.…”
