Abstract
Simple myringoplasties were performed in 35 patients with chronic otitis media with ear drum perforation. Chitin fabric only was used for 27 patients, and for the other 8, collagen artificial skin was used in addition. The success rate was 90.6% for ear drum perforations smaller than two quadrants in size. In success cases using only chitin fabric, the perforations were closed between 4 and 15 weeks, and the hearing improved to the patch test level before the operation in all patients.
The indications of this method are as follows: the perforation was positioned centrally and no discharge was noted from the middle ear, normal function of eustachian tube, and satisfactory hearing improvement by the patch test.
The author emphasizes that this method is very simple and useful for ENT outpatient clinics because it requires no admission and no autografts.
