BACKGROUND: Little information is available regarding the prevalence of lar
yngeal pathology in adults.
PURPOSE: To estimate the prevalence of occult laryngeal pathology in a comm
unity-based cohort of adults over 40 years of age.
METHODS: One hundred consecutive volunteers over age 40 with no history of
voice disorders were enrolled. All completed a self-administered laryngeal
symptom questionnaire and underwent a comprehensive head and neck examinati
on including transnasal fiberoptic laryngoscopy.
RESULTS: The mean age of the cohort was 61 years. Vocal fold bowing (presby
laryngis) was present in 72% of the patients, and findings of laryngopharyn
geal reflux were present in 64% of the cohort. In addition, other laryngeal
pathology were identified in 21%, Only 12% had a completely normal larynge
al examination.
CONCLUSIONS: Occult laryngeal pathology is very common in persons over 40,
Findings suggestive of laryngopharyngeal reflux are present in 64%, and voc
al fold bowing is present in 72% of persons over 40.
