    Summary

    The air caloric test can evaluate vestibular function in otitis media patients. Findings suggest varied caloric responses based on ear condition, including perforations and post-surgery cavities, indicating test safety in early recovery.

    Area of Science:

    • Otolaryngology
    • Neuroscience
    • Vestibular System

    Background:

    • Evaluating vestibular function is crucial for patients with otitis media.
    • The air caloric test is a potential tool for this assessment.

    Purpose of the Study:

    • To examine the application of the air caloric test in patients with otitis media.
    • To investigate vestibular responses before and after otitis media surgery.

    Main Methods:

    • Studied patients with unilateral otitis media.
    • Assessed vestibular function using air caloric testing before and after surgical intervention.

    Main Results:

    • Patients with tympanostomy tubes or small perforations may have equal caloric responses in both ears.
    • Large perforations can lead to hyperactive caloric responses.
    • Moist ears with large perforations or mastoidectomy cavities may exhibit inverted nystagmus.
    • Dry open mastoid or fenestration cavities often result in hyperactive caloric responses and vegetative symptoms.

    Conclusions:

    • The air caloric test provides insights into vestibular function in otitis media patients.
    • Specific ear conditions correlate with distinct caloric test responses.
    • The test is safe for patients in the early postoperative period.
