Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 1
Abstract
Objective: To evaluate the prevalence of cochleovestibular (CV) symptoms in acquired hypothyroidism and to establish a relation between CV symptoms and duration of hypothyroidism. Materials and Methods: An observational study of 100 patients with diagnosis of hypothyroidism on treatment and with euthyroid state. Parameters studied: gender, duration of hypothyroidism, CV symptoms, pure tone audio metry (PTA). Results: 82% were women with the predominance of the age between 30-40 years (34.6±2.87).The mean duration of hypothyroidism was 3 yrs(2.8±1.70). 56% had the diagnosis of hypothyroidism for more than 3 years. 63% of the study group had no symptoms, 21% complained of subjective hearing loss, 6% tinnitus and 2% vertigo only, 2% had hearing loss, vertigo and tinnitus, while 6% had tinnitus with hearing loss only. Based on PTA, 63% of hypothyroid patients had normal hearing,19.5% cases had sensorineural hearing loss (SNHL), 12% mixed hearing loss(MHL), and 5% had conductive hearing loss (CHL).Mild degree of hearing impairment was present in majority (27%), moderate in 8.4% and 2% had moderately severe hearing loss. None had severe and profound hearing loss. Conclusion: It was found that patients with acquired hypothyroidism on regular treatment had hearing impairment with predominance of SNHL followed by mixed and conductive type, ranging from mild to moderate in severity. Vestibular system was found to be affected minimally. It was found that there was no relation between duration of hypothyroidism with euthyroid status and CV symptoms
