Role of mitomycin-C to reduce post FESS adhesion and ostial stenosis

Abstract

The aim of this study is to determine adhesion formation rate and antrostomy closure rate after the use of Mitomycin-C in patients underwent FESS. This is a prospective case control study conducted at ENT Department Lyari General Hospital, Karachi, Pakistan. Fifty one patients included with diagnosis of bilateral chronic rhinosinusitis or allergic fungal sinusitis and were the surgical candidate, underwent bilateral Functional Endoscopic Sinus Surgery (FESS). The patients were evaluated using Lund-Mackay staging system prior to surgery. At the completion of surgery Mitomycin-c (MMC) was applied in one nasal cavity the other nasal cavity served as a control. Among fifty one patients both nostrils were used hence we have 51 cases and 51 controls. The patients were followed for a minimum period of three months after surgery. Subjective improvement of symptoms were recorded as well as rigid nasoendoscpic examination was also performed regularly. The adhesion formation rate in MMC applied nasal cavities was 11.7% as compared to 64.7% of controls. The middle meatal antrostomy closure rate was 41% and 5% in controls and MMC applied group respectively. Hence mitomycin-c application has shown benefit in reducing post FESS ostial stenosis and adhesion formation between middle turbinate and lateral nasal wall. Application of Mitomycin-C has impact on reducing post FESS adhesion formation and middle meatal antrostomy closure.
