The functional and anatomical results of a series of 122 type I tympanoplastics for drum perforation in chronic otitis media were retrospectively reviewed. Drum closure was realized in 93% at 1 year after surgery. An air-bone gap of less than 25dB was reached in 95% at 1 year after surgery. The considered influencing factors in outcomes of type I tympanoplasty, including age, size of perforation, middle ear pathology, technique of closure of perforation and status of ossicular mobility were evaluated.
