特発性鼻咽腔狭窄例

抄録

Idiopathic nasopharyngeal stenosis is a rare disease entity and a standard treatment has not been established. A 71-year-old woman visited our hospital with bilateral nasal obstruction. Nasal fiberscopy showed severe nasopharyngeal stenosis. Muscles including the palatal tensor Levator veli palatine muscle and surrounding submucosal connective tissue looked intact on MRI. Inflammatory findings were not observed with pathological examination of biopsied tissue from the nasopharynx. Nasopharyngoplasty using a pedicled musculomucosal flap harvested from the buccal region was performed. Recurrence of the nasopharyngeal stenosis has not been observed in a 1-year follow-up.
