ABSTRACT
UNLABELLED: The prognostic significance of vertigo in patients with idiopathic sudden sensorineural hearing loss (SSNHL) remains a matter of debate. OBJECTIVE: This paper aims to verify the difference between a group with vertigo and a group without vertigo, and to analyze vertigo's validation as a prognostic factor in patients with SSNHL. METHOD: This study involved 183 patients with SSNHL. A t-test was used to compare group A (SSNHL with vertigo, n = 31) and group B (SSNHL without vertigo, n = 152). Also we want to verify the interaction effects between vertigo and other prognostic factors using multiple regression analysis. RESULTS: There was a significant difference between group A and group B: the initial hearing level of group A was lower than group B, and their treatment onset was also shorter. In addition, vertigo itself didn't affect hearing improvement, but the interaction variable between vertigo and initial hearing level did affect hearing improvement significantly. CONCLUSION: The clinical characteristics of patients with vertigo did not directly affect hearing improvement with SSNHL; however, vertigo had an influence on SSNHL though its interaction with the initial hearing levels.

O significado prognóstico de vertigem em pacientes com perda auditiva neurossensorial súbita idiopática (PANSI) continua a ser uma questão controversa. OBJETIVO: Este trabalho tem como objetivo verificar a diferença entre um grupo com vertigem e um grupo sem vertigem e analisar a validação da vertigem como fator prognóstico em pacientes com PANSI. MÉTODO:Este estudo envolveu 183 pacientes com PANSI. O teste t foi utilizado para comparar o grupo A (PANSI com vertigem, n = 31) e o grupo B (PANSI sem vertigem, n = 152). Também queremos verificar os efeitos de interação entre vertigem e outros fatores prognósticos por meio de análise de regressão múltipla. RESULTADOS: Houve uma diferença significativa entre o grupo A e o grupo B: o nível auditivo inicial do grupo A foi menor do que no grupo B, e seu início de tratamento também foi menor. Além disso, a vertigem em si não afetou a melhora da audição, mas a variável de interação entre vertigem e nível de audição inicial afetou significativamente a melhora da audição. CONCLUSÃO: As características clínicas dos pacientes com vertigem não afetaram diretamente a melhora da audição de pacientes com PANSI; no entanto, vertigem teve uma influência sobre a PANSI por meio de sua interação com os níveis iniciais de audição.
