title: Seasonal allergic rhinitis and its effects on eustachian tube function and middle ear pressure.
abstract: Middle ear pressure was recorded from 396 ears and aural symptoms inquired of 198 adult subjects with seasonal allergic rhinitis. Evidence of eustachian tube dysfunction was found in 24% of subjects. Increased duration of exposure to pollen over a further 2 weeks increased the incidence of eustachian tube dysfunction to 48%. The development of eustachian tube dysfunction did not correlate with the severity of nasal symptoms.
