Upper respiratory tract infection and eustachian tube function in children
Acta Oto-Laryngologica
|March 1, 1984
Summary
Upper respiratory tract infections (URTI) impair children's Eustachian tube function, worsening middle ear pressure and increasing effusion risk. This may explain frequent middle ear issues in children, especially those with existing tubal problems.
Area of Science:
- Otolaryngology
- Pediatric Medicine
- Respiratory Medicine
Background:
- Eustachian tube dysfunction is common in children.
- Upper respiratory tract infections (URTI) are frequent in pediatric populations.
- Middle ear effusion (MEE) is a prevalent condition in children, often linked to Eustachian tube issues.
Purpose of the Study:
- To investigate the impact of URTI on Eustachian tube function in children.
- To correlate changes in Eustachian tube mechanics during URTI with middle ear pressure and effusion development.
Main Methods:
- Studied Eustachian tube function in 11 children aged 3-9 years.
- Compared function with and without active upper respiratory tract infection (URTI).
- Assessed active muscular opening function, passive pressure opening/closing levels, and middle ear pressure.
Main Results:
- URTI significantly deteriorated the active muscular opening function of the Eustachian tube.
- Middle ear pressure weakened during URTI.
- Passive pressure opening and closing levels, indicating tubal closing forces, increased during URTI.
Conclusions:
- URTI negatively affects Eustachian tube function in children.
- Impaired tubal opening and altered closing forces during URTI may lead to transient middle ear underpressure and MEE.
- Children with pre-existing Eustachian tube hypofunction are at higher risk for recurrent or persistent MEE when experiencing URTI.
