Etiology
Pathology
- eustachian tube fails to equalize pressure between the middle ear & the atmosphere, resulting in negative middle-ear pressure
Clinical manifestations
- otalgia, muffled hearing, tinnitus, aural fullness
- may occur in the setting of nasal congestion & cough
Diagnostic procedures
- Weber test lateralizes to the side of eustachian tube dysfunction
- otoscopy:
- tympanic membrane intact, but appears dull & retracted
- tympanic membrane does not move with pneumatic otoscopy[3]
- tympanic membrane appears thickened with amber hue[3]
Complications
- recurrent middle-ear infections requiring myringotomy & tube placement
- chronic otitis media with tympanic-membrane retraction & cholesteatoma
Management
- observation
- pseudoephedrine does not appear to shorten recovery period[3]
- eustachian tube balloon dilation system FDA approved to dilate stenotic eustachian tube in adults
