耳科门诊中耳鸣与听力损失的关联性研究OA

OBJECTIVE To investigate the prevalence of tinnitus and hearing loss in otology patients,and to analyze the characteristics and relationship of tinnitus and hearing loss in different age groups.METHODS A total of 4 716 patients who visited otology clinic were enrolled.Age,gender,and presence or absence of tinnitus were recorded.All patients completed pure tone audiometry.The characteristics and relationship between tinnitus and pure tone audiometry threshold were analyzed after age grouping.RESULTS 1.Among the 4 716 patients,2 772 patients had tinnitus,accounting for 58.78%,and the incidence was highest in the 41-70 years old group.3 521 cases(74.66%)had hearing loss.2.Among the patients with tinnitus,2 227 cases(80.34%)had hearing loss,which was higher than that of patients without tinnitus(66.56%,1 294/1 944 cases).There was a difference in the incidence of hearing loss between those with and without tinnitus in each age group from 11 to 70 years(P<0.05).3.The average hearing threshold of patients with tinnitus was higher than that of patients without tinnitus.There was a difference in the average hearing threshold between patients with and without tinnitus in each age group over 30 years old(P<0.05).4.The incidence of high frequency hearing loss with tinnitus was 24.57%(681/2 772),and the incidence of without tinnitus was 21.66%(421/1 944).The rate of high-frequency hearing loss in the 21-40 years old group with tinnitus was higher than that in the non-tinnitus group(P<0.05).CONCLUSION The incidence of hearing loss is higher and more severe in patients with tinnitus.Particular attention should be paid to tinnitus in young patients.The incidence of high-frequency hearing loss was higher in the young and middle-aged group of patients with tinnitus.Therefore,the evaluation of hearing threshold in patients with tinnitus is very important,which can provide a basis for clinical diagnosis and treatment.
