Methods 109 patients(109 ears) with perforations of the ear drum were recruited from November 2007 to March 2009 . The patients were divided into 3 groups according to the size and position of perforations of the ear drum: 31 accepted myringoplasties with a fat plug , 43 accepted perichondrium via endotoscope, and 35 accepted fascia musculares via an operating microscope.
