A review of 925 cases of tympanoplasty using formaldehyde-formed-fascia grafts.

In this review of 925 cases of total and anterior perforations of the tympanic membrane reconstructed through the use of formaldehyde-formed-fascia (3-F) grafts, the postoperative nonperforation rate is 97.6%; blunting and/or lateralization of the graft was avoided in 93.5% of cases. Closure of the postoperative air-bone gap within 20 dB was achieved in 70% of cases. This update of a previously reported paper reinforces our opinion that the 3-F graft is an effective tool for the closure of tympanic membrane perforation with or without ossicular chain reconstruction.
