Introduction:Idiopathic Sudden Sensorineural Hearing Loss as a subset of sensorineural hearing loss will be confirmed by a progressive hearing loss of at least 30 dB at three contiguous frequencies over 72 hours or less. A sudden or abrupt hearing loss correlates with the time course, and a vascular event is presumptive aetiology. There is an inverse association between Omega-3 consumption and hearing loss. This study aimed to evaluate the efficacy of Omega-3 adjunctive therapy in Idiopathic Sudden Sensorineural Hearing Loss by audiometric assessments.Materials and Methods:In this randomised, triple-blind, placebo-controlled trial, all participants aged 18-70 with a history of sudden deafness (within 12 hours and ≤ 30 days) were eligible for enrollment. They were included if audiology diagnostic tests confirmed the SSNHL. Ultimately, they were randomised to the Omega-3 group and the placebo group.Results:Thirty-three patients were randomly allocated to the Omega-3 group and thirty-two to the placebo group. Vertigo (32.3% of all patients) and underlying conditions had significant relationships with complete response (C.R.)-final hearing level ≤of 25 dB in pure-tone average (P < 0.05). There was no significant difference between both groups before and after treatment. Although it was not statistically significant, patients in the Omega-3 group had faster recovery than placebo.Conclusions:Omega-3 adjunctive therapy did not have a therapeutic effect on SSNHL patients. Moreover, C.R. happened in half the patients. Vertigo and underlying conditions considerably worsen the recovery from SSNHL.
