Formaldehyde fasciaform tympanoplasty: a reliable technique for closing large tympanic membrane perforations.

Author information

Division of Otolaryngology, University of British Columbia, Vancouver.


Formaldehyde fasciaform grafting tympanoplasty is a reliable method, in experienced hands, to close large tympanic membrane perforations. The technique involves using autogenous temporalis fascia shaped by formaldehyde cross-linking on a special fasciaform mold (Hear America, Palo Alto, CA). This study was undertaken with the objective of assessing if an otologist with less experience in using this technique could obtain comparable results. The results of the initial 23 patients treated in this manner by one surgeon between August 1996 and January 1998 are reviewed. Success was measured by the rate of closure of the tympanic membrane perforation and by functional closure of the air-bone gap. Favourable results were obtained, with complete closure of 86% of the perforations and closure of the air-bone gap to 20 dB or less in 90% of subjects when the ossicular chain was intact. The formaldehyde fasciaform tympanoplasty technique produces consistent, reliable, and reproducible results for large tympanic membrane perforations.
