A Clinical Study of Human Type IV Collagen as Tympanic Membrane Grafting Material: Preliminary Noncomparative Study

Abstract

A human type IV collagen film may be a possible alternative to autologous tissue in tympanic membrane reconstruction. This new biomaterial was tested on patients with various diseases common in clinical otology, and demonstrated a good biocompatibility of MTY in the different pathologic conditions of chronic otitis media. A future randomized, controlled trial will randomly allocate patients to receive either MTY collagen film or tissue from the temporal aponeurosis.
