Raw avian membrane as biomaterial for myringopexy

Myringopexy with raw avian membrane came out due to the necessity of establishing the influence of the perforation of the tympanic membrane characteristics on hearing after its closure. The aim of this study was to present a new technique for repairing the defects of the tympanic membrane and to obtain cheap, easy to get and effective biomaterial for myringopexy. The novelty lies in its innovative character and a better resistance in time of the neo-membrane as compared to the avian membrane thermally treated or to other types of mentors. The clinic-experimental study was carried out on a group of 230 patients, from patients within the ENT Clinic of, Saint Apostle Andrew" Emergency Hospital Galati which have been examined by otoscopy and microotoscopy. A number of 238 perforated tympanum membranes had been found (some patients presented with perforations on both ears); six of the examined tympanum had two perforations each, so a total of 244 perforations had been examined. A number of 182 patients with 188 perforations had suffered surgery for closing the perforations. The investigations are part of a succession of studies that have the purpose of establishing the relationship between tympanic perforation and transmission hypoacusia. The results are promising and lead to closure of the rupture/perforation with thin tympanic membrane and a significant improvement of the auditive function, without side-effects by using cheap biomaterials.
