Summary
Hypothyroidism can cause sensorineural hearing loss and vestibular issues. Brainstem auditory evoked potentials were normal, but central vestibular disturbances were evident in patients.
Area of Science:
- Otolaryngology
- Endocrinology
- Neuroscience
Context:
- Hypothyroidism is associated with various systemic complications.
- Cochlear and vestibular functions can be affected by endocrine disorders.
Purpose:
- To investigate cochlear and vestibular disturbances in hypothyroidism.
- To characterize the audiological and vestibular findings in hypothyroid patients.
Summary:
- The study found sensorineural deafness, often flat-type without recruitment, in most hypothyroid patients.
- While brainstem evoked potentials were normal, myogenic potentials showed reduced amplitude.
- Vestibular examination revealed central disturbances and saccadic pursuit during tracking tests.
Impact:
- Highlights the audiological and vestibular impact of hypothyroidism.
- Provides insights into the central and peripheral nervous system involvement.
- Informs clinical evaluation and management of hypothyroid-related neurosensory deficits.
