RESUMEN
OBJECTIVES: The aim of this study is to investigate the efficacy of topical application of mitomycin C after dilation in pediatric patients having post corrosive esophageal stricture. METHODS: Thirty patients with post corrosive esophageal strictures were divided into two groups: 12 patients had repeated esophageal dilation without mitomycin C application, 18 patients had repeated esophageal dilation and topical application of mitomycin C. RESULTS: There was a highly significant difference in the improvement of dysphagia grade at the end of follow up in the mitomycin C group (p=0.005). The number of repetition of dilatation ranged from 2 to 6 (median=3) in the 1st group, and 2 to 4 (median=2.5) in the mitomycin C group. There were no adverse effects from the topical application of the mitomycin C. CONCLUSIONS: Topical application of mitomycin C after oesophageal dilation can be beneficial in improving dysphagia in patients with post corrosive oesophageal stricture.

BACKGROUND: The purpose of this study was to investigate the role of intraoperative application of mitomycin C in prevention of glottic restenosis after posterior transverse CO2 laser cordotomy (PTLC) for patients with post-thyroidectomy bilateral vocal fold paralysis. METHODS: Twenty-five patients with an impaired airway because of bilateral vocal fold paralysis were treated with PTLC. Patients were divided into groups: the mitomycin C group (13 patients) had PTLC and topical mitomycin C; and the control group (12 patients) had PTLC only. RESULTS: No patients in the mitomycin C group developed glottic granulation or laryngeal scarring, whereas 5 of 12 patients in the control group developed granulation (p = .014) and 2 of 12 patients had laryngeal scarring (p = .28). Ten of 13 patients in the mitomycin C group ended up with mild dyspnea with no limitation to normal everyday activities whereas only a third of the control group achieved this outcome (p = .05). CONCLUSION: The use of topical mitomycin C has been shown to decrease postoperative laryngeal granulation, scarring, restenosis, and the need for revision surgery.
