Treatment of Nasopharyngeal Stenosis after Revisional Palatopharyngoplasty with Balloon Dilatation and Topical Mitomycin-C Application / 대한이비인후과학회지

ABSTRACT

Nasopharyngeal stenosis (NPS) is a rare condition and classified as primary NPS (due to a disease process as syphilis) or secondary NPS (due to a surgery or radiotherapy) according to the etiology. Patients with NPS suffer significant morbidities, including nasal obstruction, phonatory changes, sleep disordered breathing, dysphagia, and otologic disturbances. Treatment modalities include wide range of strategies, such as local rotation flaps, free flaps, Z-plasty, prolonged stenting, insertion of obturators, and laser excision. However, treatment is difficult, often resulting in only short-term symptom relief and restenosis. The authors experienced a case of NPS following revisional palatopharyngoplasty in a 50-year-old man, which was treated successfully with balloon dilatation and topical mitomycin-C application. We present the etiology, symptoms, and treatment of this rare disease entity with a review of the literature.
