Tympanometry in children with allergic respiratory disease

Area of Science:

• Pediatric Allergy and Immunology
• Otolaryngology
• Diagnostic Audiology

Background:

• Children with allergic rhinitis or asthma often present with middle ear issues.
• Accurate diagnosis of middle ear disease is crucial for effective management in allergic pediatric populations.

Purpose of the Study:

• To compare pneumatic otoscopy and tympanometry in diagnosing middle ear conditions in children undergoing allergy clinic follow-up.
• To assess the utility of tympanometry as an adjunct diagnostic tool in this specific pediatric cohort.

Main Methods:

• A study involving 102 children followed in an allergy clinic.
• Comparison of findings from pneumatic otoscopy and tympanometry, including tympanogram types and acoustic reflex thresholds.
• Evaluation of inter-examiner agreement for tympanometry over the study period.

Main Results:

• Forty-five abnormal tympanograms were identified in 30 children, with various classifications (Type B, Type C, reduced compliance).
• Absent or significantly elevated acoustic reflexes were noted in 34 children (45 ears).
• Inter-examiner agreement for tympanometry showed significant improvement, increasing from 62% to 75%-79%.

Conclusions:

• Tympanometry provides objective data crucial for evaluating middle ear disease in children with allergic conditions.
• The study highlights tympanometry's role in enhancing the diagnostic capabilities within allergy clinics.
• Improved examiner agreement suggests a learning curve and increased reliability of tympanometry with practice.
