Tissue culture of surgically prepared temporalis fascia.
Temporalis fascia which is used to graft the tympanic membrane has been shown to be viable in tissue culture by a previous pilot study. This present study reports the effect on the viability of the fascia by scraping loose connective tissue from it and allowing it to dry. Pieces of fascia from 30 patients were each divided in 4 and prepared to give explants, fresh, fresh and scraped, dried, and dried and scraped. The fascia grew from 17 patients when cultured fresh, 5 when fresh and scraped, 1 when dried, and none when dried and scraped. These results are significantly different and show that the fascia is devitilized when prepared by the normal method for use in tympanoplasty.
