Summary
Diagnostic tests like ECochG, caloric tests, and VEMP are crucial for identifying delayed endolymphatic hydrops (DEH). These methods help determine the affected side and severity of DEH, aiding in routine clinical diagnosis.
Area of Science:
- Otolaryngology
- Neurotology
- Audiology
Context:
- Delayed endolymphatic hydrops (DEH) presents diagnostic challenges.
- Accurate diagnosis is essential for effective management of DEH.
Purpose:
- To evaluate the diagnostic utility of pure tone threshold, electrocochleography (ECochG), bithermal caloric testing, and vestibular evoked myogenic potentials (VEMP) for DEH.
- To assess the significance of these tests in identifying the lesioned side and hydrops extent in DEH patients.
Summary:
- Fifteen DEH patients underwent audiological and vestibular testing.
- Results indicated sensorineural hearing loss in all patients, with varying laterality.
- Abnormalities in horizontal semicircular canal (HSCC) and saccular function were observed, with specific VEMP alterations noted.
Impact:
- ECochG, caloric tests, and VEMP are vital for DEH diagnosis.
- These tests should be incorporated into routine diagnostic protocols for DEH.
- Improved diagnostic accuracy can lead to timely and appropriate patient care.
