Long-term results of the use of cultured autologous epithelial cell grafting to mastoid cavities.

ABSTRACT

Thirty-nine patients (42 ears) who have had a cultured autologous epithelial cell graft technique to a continuously discharging mastoid cavity have been evaluated to determine the continued effectiveness of this procedure. A postal questionnaire indicated a 58% improvement in both the smell and quantity of discharge, and our conclusion is that this is a very effective measure to provide extended symptomatic improvement in this troublesome condition.
