<prompt> Topical Mitomycin C is useful in treatment ofAngiofibromaTracheal stenosisSkull base OsteomyelitisLaryngeal carcinoma  <response>: Dilation for laryngotracheal stenosis is typically done using serial dilation using various sizes of Jackson bronchoscopes. The various studies have showed that mechanical dilation used alone can have a recurrence rate of stenosis of greater than 90. Thus, various adjunctive procedures have been developed in order to try to decrease the rate of restenosis. Mitomycin-C is an example of one of these adjunctive agents. Ref : Internet sources
