RESUMEN
ABSTRACT INTRODUCTION: This cross-sectional comparative study was carried out at the Diabetes outpatient clinic of LAUTECH Teaching Hospital (LTH) Ogbomoso, Nigeria. OBJECTIVE: This study assessed patterns of otologic diseases and auditory acuity among type 2 diabetics and determinants of these findings among diabetics. METHODS: Ninety-seven consenting patients with clinical diagnosis of diabetes mellitus (194 ears) were matched for age and sex with ninety non-diabetic patients (180 ears). These patients were screened using otoscopy and pure tone audiometry over a 6-month period. RESULTS: The study reported a crude prevalence rate of 21.6% hearing loss in T2DM patients. The most common type of otologic disease that showed significant association with T2DM patients was otitis media with effusion (p = 0.027). T2DM was significantly associated with abnormal audiometric findings (p = 0.022), particularly sensorineural hearing loss (p = 0.022), of the moderate grade (p = 0.057). There were no differences of the audilogical findings for any particular ear, and no differential affectation of frequency range was observed. Coexisting hypertension and poor glycaemic control were significantly associated with aggravation of the hearing of the T2DM patients (p < 0.001, and p = 0.009 respectively). CONCLUSION: T2DM had appreciable effects on hearing acuity. T2DM was significantly associated with the type and the degree of the hearing loss. The need for screening of hearing acuity of T2DM patients, in order to detect early changes, and promptly offer an adequate management and remedial measures was emphasized in this study.
Resumo Introdução: Este estudo de caso-controle foi realizado no Ambulatório de Diabetes do LAUTECH Teaching Hospital (LTH), em Ogbomoso, Nigéria. Objetivos: Este estudo avaliou os padrões de doenças otológicas e acuidade auditiva entre os diabéticos tipo 2 e os fatores determinantes desses achados entre os diabéticos. Método: Ao todo, 97 pacientes com diagnóstico clínico de diabetes melito (194 orelhas) deram seu consentimento e foram pareados por idade e sexo, com 90 pacientes não diabéticos (180 orelhas). Eles foram avaliados por otoscopia e audiometria tonal liminar por um períodode seis meses. Resultados: O estudo relatou uma taxa de prevalência bruta de 21,6% de perda auditiva em pacientes com DM2. O tipo mais comum de doença otológica, afetando significativamente pacientes com DM2, foi otite média com efusão (p = 0,027). A DM2 foi associada com achados audiométricos alterados (p = 0,022), principalmente perda auditiva neurossensorial (p = 0,012), de grau moderado (p = 0,057). Não houve predileção dos efeitos da DM2 para uma das orelhas em particular, e também não houve efeito diferencial da faixa de frequência. A coexistência de hipertensão e controle glicêmico inadequado associou-se significativamente à piora da audição dos pacientes com DM2 (p < 0,001 e p = 0,009, respectivamente). Conclusão: A DM2 mostrou apresentar efeitos significantes na acuidade auditiva afetando significativamente o tipo e o grau da disacusia. Este estudo mostrou a necessidade de avaliação da acuidade auditiva de pacientes com DM2, a fim de detectar as alterações iniciais, e poder rapidamente oferecer medidas corretivas adequadas.
