Topical Mitomycin C is useful in treatment of?

Laryngotracheal stenosis treated by serial dilatation using Jackson bronchoscopes. Laser have tendency to recur and hence adjuvant methods are done to decrease the rate of restenosis.

It is an alkylating agent which has both antineoplastic and antiproliferative propeies and inhibits fibroblast production and thus prevents restenosis.
