Seasonal allergic rhinitis and its effects on eustachian tube function and middle ear pressure.
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.
