Debutul subliminal al surdităţii neurosenzoriale brusc instalate în hipotiroidism – revizuire a literaturii

Abstract

Sudden sensorineural hearing loss (SSNHL) is a frequent oc­cur­rence in audiology and otolaryngology. It refers to a sen­so­rineural hearing loss of 30 dB or more across three con­se­cu­tive audiometric frequencies, developing within 72 hours. While the causes of SSNHL vary widely, most cases lack a clear origin. Studies have suggested a po­ten­tial re­la­tion­ship between thyroid dysfunction and the onset of SSNHL, yet establishing a definitive causal link re­mains un­cer­tain. Our review aims to meticulously explore the impact of thyroid function on SSNHL. The treatment for SSNHL with iden­ti­fiable causes typically targets the un­der­lying agent, often resulting in poor hearing outcomes due to inner ear hair cell damage. In cases of idiopathic SSNHL, steroid the­r­apy is the current standard of care. The prognosis for hea­r­ing recovery in idiopathic SSNHL hinges on factors such as the severity of hearing loss, age, presence of vertigo, and le­­­vels of thyroid hormones.
