title: [Indications for silastic and gelation film in tympanoplasty. Analysis of 624 cases using EDP (author's transl)].
abstract: Statistical analysis shows that the regular use of silastic sheet in all cases of extensive defects of the middle-ear mucosa (ensuring a mucosa-lined space) or advanced inflammatory changes (draining the cavity and tube) can eliminate negative influences of pathological conditions of the middle-ear on the long-term functional results, provided the sheet is removed when the remaining air-bone gap within the main speech range exceeds 10 dB after the ear has healed. Resorbable gelatin film implants should be used in minor inflammatory changes, less extensive mucosal defects, and subtotal perforations of the drum.
