Abstract
BACKGROUND:
Hypothyroidism is known to be associated with impairment of hearing. The hearing impairment may be conductive, sensorineural, or mixed.
AIMS:
The aim is to assess the auditory pathway by brainstem auditory evoked potentials (BAEPs) in newly diagnosed patients of subclinical hypothyroidism and healthy sex- and age-matched controls.
MATERIALS AND METHODS:
The study included 25 healthy sex- and age-matched controls (Group I) and 25 patients of newly diagnosed subclinical hypothyroidism (Group II). The recording was taken by using RMS EMG EP MK2 equipment. The unpaired Student's t-test was used and a P value <0.05 was considered significant.
RESULTS:
Wave V of right ear BAEP in group II was prolonged (6 ± 0.62 ms) compared to group I (5.49 ± 0.26 ms), and wave V of left ear BAEP in group II was prolonged (5.84 ± 0.57 ms) compared to group I (5.47 ± 0.35 ms). There was no significant coefficient of correlation between wave V and inter-peak latency (IPL) I-V compared to thyroid-stimulating hormone (TSH) levels of both the ears.
CONCLUSION:
The prolongation of wave V in BAEPs of both ears suggests that the central auditory pathway is affected significantly in subclinical hypothyroid patients.
