Toynbee phenomenon and middle ear disease
The American Journal of Otology
|April 1, 1984
Summary
Toynbee's maneuver, a swallowing technique, can cause positive middle ear pressure. This pressure increase is more common in individuals with middle ear disease, suggesting a link to the condition.
Area of Science:
- Otolaryngology
- Medical research
Background:
- Acute otitis media (AOM) often involves bacterial spread from the nasopharynx to the middle ear via the Eustachian tube.
- Understanding factors influencing middle ear pressure is crucial for AOM pathogenesis research.
Purpose of the Study:
- To investigate the effect of Toynbee's maneuver on middle ear pressure.
- To determine if positive middle ear pressure during this maneuver is associated with middle ear disease.
Main Methods:
- Measurement of middle ear pressure following Toynbee's maneuver (swallowing against occluded nostrils).
- Comparison of results between normal individuals and patients diagnosed with middle ear disease.
Main Results:
- A small percentage (2%) of healthy individuals developed positive middle ear pressure after the maneuver.
- A significantly higher proportion (56%) of patients with middle ear disease exhibited positive middle ear pressure.
Conclusions:
- Toynbee's maneuver can induce positive middle ear pressure.
- The increased incidence of positive middle ear pressure in patients suggests it may be a contributing factor in the development or exacerbation of middle ear disease.
