“…Previous studies have shown that abnormal VEMP is indicative of poor prognosis regardless of the onset of vestibular symptoms in patients with sudden deafness ( 22 , 23 ). Shih et al found that abnormal caloric test results were significantly associated with poor prognosis in patients with sudden deafness and that CP values were significantly associated with hearing recovery in patients with abnormal caloric test ( 24 ).…”

BackgroundSevere and profound idiopathic sudden sensorineural hearing loss (ISSNHL) generally leads to unfavorable prognosis, and has a considerable impact on patient quality of life. However, related prognostic factors remain controversial.ObjectiveTo elaborate the relationship between vestibular function impairment and the prognosis of patients with severe and profound ISSNHL, and investigated the relevant factors affecting prognosis.MethodsForty-nine patients with severe and profound ISSNHL were divided into good outcome group [GO group, pure tone average (PTA) improvement > 30 dB] and poor outcome group (PO group, PTA improvement ≤ 30 dB) according to hearing outcomes. The clinical characteristics and the proportion of abnormal vestibular function tests in these two groups were analyzed by univariate analysis, and multivariable logistic regression analysis was performed for parameters with significant differences.ResultsForty-six patients had abnormal vestibular function test results (46/49, 93.88%). The number of vestibular organ injuries was 1.82 ± 1.29 in all patients, with higher mean numbers in PO group (2.22 ± 1.37) than in GO group (1.32 ± 0.99). Univariate analysis revealed no statistical differences between the GO and PO groups in terms of gender, age, side of the affected ear, vestibular symptoms, delayed treatment, instantaneous gain value of horizontal semicircular canal, regression gain value of vertical semicircular canal, abnormal rates of oVEMP, cVEMP, caloric test and vHIT in anterior and horizontal semicircular canal, however, significant differences were found in the initial hearing loss and abnormal vHIT of posterior semicircular canal (PSC). Multivariable analysis revealed that only PSC injury was an independent risk factor for predicting the prognosis of patients with severe and profound ISSNHL. Patients with abnormal PSC function had worse initial hearing impairment and prognosis than patients with normal PSC function. The sensitivity of abnormal PSC function in predicting poor prognosis in patients with severe and profound ISSNHL was 66.67%, specificity was 95.45%, and positive and negative likelihood ratios were 14.65 and 0.35, respectively.ConclusionAbnormal PSC function is an independent risk factor for poor prognosis in patients with severe and profound ISSNHL. Ischemia in the branches of the internal auditory artery supplying the cochlea and PSC may be the underlying mechanism.

“…It is believed that the prognosis regarding hearing recovery may be related to several factors, such as the patient’s age, presence of vertigo at symptom onset, degree and configuration of the hearing loss observed in the audiometry and the time between hearing loss onset and the treatment. 2 Studies that performed the vestibular assessment using VEMP, 1 , 5 , 6 , 7 vHIT 8 and caloric testing 1 , 5 , 9 in patients with SHL observed that the abnormal results in these tests could also be related to a worse hearing prognosis.…”

“…Hearing loss can be analyzed through audiometric tests and, thus, divided into sensorineural, conductive or mixed, according to the pattern of lowering of auditory thresholds, being classified in degrees ranging from mild to profound 2,5 . Some of these tests include pure tone audiometry, logoaudiometry, immitanciometry/ tympanometry, brainstem auditory evoked potentials (BAEP), otoacoustic emissions (OAE) and vestibular evoked myogenic potential (VEMP) 5,6 . Regarding its etiology, hearing loss has several causes, including infections, genetic factors, environmental factors, chronic diseases and the metabolic syndrome, including its components, mainly hypertension, dyslipidemia and diabetes 1,7,8 .…”

Introdução: Perdas auditivas correspondem à quarta maior causa de incapacitação no mundo, com mais de um bilhão de pessoas com algum grau de perda, acarretando elevados gastos anuais. O déficit auditivo pode ser consequência de infecções, fatores genéticos, ambientais e comorbidades como hipertensão e diabetes mellitus (DM). Apesar de ainda o papel da DM na perda auditiva ser incerto, estudos sugerem que a microangiopatia e neuropatia diabéticas estejam envolvidas. Objetivo: Avaliar o perfil audiométrico de pacientes com DM atendidos em um ambulatório em Curitiba-PR. Métodos: Estudo observacional transversal com avaliação de 41 pacientes diabéticos entre abril de 2020 e março de 2021 quanto a queixa auditiva, presença de comorbidades e grau e tipo de perda auditiva. Resultados: A média de idade foi de 66,3 anos, sendo 63,4% do sexo feminino e o valor médio da hemoglobina glicada (HbA1c) foi de 7,67%. 82,9% dos pacientes apresentaram tinnitus e 68,3% apresentaram hipoacusia. 36,6% apresentaram hipertensão, enquanto 80,5% tinham dislipidemia. Quanto ao controle de glicemia, 65,9% tinham HbA1c ≥ 7%. Conclusões: A DM pode estar associada com perda auditiva, não sendo, contudo, possível constatar uma clara correlação de causa e efeito. Assim, novos estudos, mais aprofundados e com um N maior, são necessários.
