Abstract Sudden hearing loss is a significant otologic emergency. Previous studies have revealed a coexistence of sudden hearing loss with chronic inflammation. The predictive importance of C-reactive protein/albumin values as a prognostic factor has been shown in various inflammatory and tumoral conditions. The aim of this study was to determine whether the C-reactive protein/albumin ratio in sudden hearing loss can be used for prognostic purposes and whether there is a relationship between the neutrophil/lymphocyte ratio and the C-reactive protein/albumin ratio. A retrospective examination was made of 40 patients diagnosed with idiopathic sudden hearing loss and a control group of 45 healthy subjects. The pure tone averages of all the patients were determined on first presentation and repeated at 3 months after the treatment. The patients were separated into 2 groups according to the response to treatment. The neutrophil/lynphocyte ratio and the C-reactive protein/albumin ratios were calculated from the laboratory tests. The patients included 16 females and 24 males with a mean age of 44.1±14.2 years and the control group was composed of 23 females and 22 males with a mean age of 42.2±13.8 years. The mean C-reactive protein/albumin ratio was 0.95±0.47 in the patient group and 0.74±0.13 in the control group. The difference was statistically significant (p=0.009). The mean C-reactive protein/albumin ratio was 0.79±0.12 in the response to treatment group and 1.27±0.72 in the non-response group, with no significant difference determined between the groups (p=0.418). The mean neutrophil/lymphocyte ratio was 3.52±3.00 in the response to treatment group and 4.90±4.60 in the non-response group, with no statistically significant difference determined between the groups (p=0.261). C-reactive/albumin ratio was significantly higher in patients with sudden hearing loss than in the control group. Although C-reactive protein/albumin ratio was found to be lower in sudden hearing loss patients who responded to treatment compared to those who did not, the difference between two groups was not statistically significant. A perda auditiva neurossensorial súbita ou surdez súbita é uma emergência otológica significativa. Estudos anteriores revelaram uma coexistência dessa condição com inflamação crônica. A importância preditiva dos valores da relação proteína C-reativa/albumina como fator prognóstico tem sido demonstrada em várias condições inflamatórias e tumorais. O objetivo deste estudo foi determinar se a relação proteína C-reativa/albumina na perda auditiva neurossensorial súbita pode ser usada para fins prognósticos e se existe uma associação entre as relações neutrófilo/linfócito e proteína C-reativa/albumina. Foram avaliados retrospectivamente 40 pacientes com diagnóstico de perda auditiva neurossensorial súbita idiopática e um grupo controle de 45 indivíduos saudáveis. As médias de tons puros de todos os pacientes foram determinadas na primeira consulta e repetidas 3 meses após o tratamento. Os pacientes foram separados em 2 grupos de acordo com a resposta ao tratamento. As relações neutrófilo/linfócito e proteína C-reativa/albumina foram calculadas a partir de testes laboratoriais. Os pacientes incluíam 16 mulheres e 24 homens, com média de 44,1±14,2 anos, e o grupo controle por 23 mulheres e 22 homens, com média de 42,2±13,8 anos. A média da relação proteína C-reativa/albumina foi de 0,95±0,47 no grupo de pacientes e de 0,74±0,13 no grupo controle e a diferença foi estatisticamente significante (p=0,009). A média da relação proteína C-reativa/albumina foi de 0,79±0,12 do grupo com resposta ao tratamento e de 1,27±0,72 no grupo sem resposta, sem diferença significante entre os grupos (p=0,418). A média da relação neutrófilo/linfócito foi de 3,52±3,00 no grupo com resposta ao tratamento e de 4,90±4,60 no grupo sem resposta, sem diferença estatisticamente significativa entre os grupos (p=0,261). A relação proteína C-reativa/albumina foi significantemente maior nos pacientes com perda auditiva neurossensorial súbita do que no grupo controle. No entanto, embora a relação proteína C-reativa/albumina tenha sido menor nos pacientes com perda auditiva neurossensorial súbita que responderam ao tratamento em comparação a aqueles que não apresentaram resposta, a diferença entre os dois grupos não foi estatisticamente significante.
