[The investigation rate and influence factors of tinnitus with chronic suppurative otitis media]

Objective:To investigate the incidence of tinnitus and its influencing factors in patients with chronic suppurative otitis media, and to provide clinical data for the study of the pathogenesis of tinnitus.Method:The clinical data of 77 patients with chronic suppurative otitis media who underwent modified radical mastoidectomy and tympanoplasty were investigated. When tinnitus and otitis media happened in the same side,then the tinnitus is judged to be otitis media related. Patients were further divided into otitis media related tinnitus and the no tinnitus groups. The differences of tinnitus severity, sleep disturbance, migraine (migraine features), snoring and gastroesophageal reflux were compared between the two groups in tinnitus occurrence and classification.Result:The incidence of otitis media related tinnitus was 55.8%(43/77). Most of the tinnitus happened(33/43) later than the occurrence of otitis media for several years or even decades. There were 43 cases of tinnitus associated with otitis media, and 31 cases without tinnitus. Between the groups, significant differences were observed in migraine features, and the P value is 0.011, while no significant differences were noticed in the severity of hearing loss and sleep disorders, snoring, gastroesophageal reflux. Ranking of otitis media related tinnitus was positively related to the degree of hearing loss, especially the bone conduction threshold. With Spearman rank correlation test,P values of mean value(250Hz,500Hz,1kHz,2kHz,4kHz), middle frequency (1kHz, 2kHz)and high frequency (4kHz) of bone conduction threshold were 0.010,0.019 and 0.003, and the correlation coefficients were 0.391,0.356 and 0.443, respectively.Conclusion:The occurrence of tinnitus in patients with otitis media may not be consistent with the time of otitis media, and theoretically later than the occurrence of otitis media is more reasonable. Whether tinnitus occurs in patients with otitis media is not related to sleep disorders, the degree of air conduction and bone conduction hearing loss, but is related to migraine features. The severity of tinnitus associated with otitis media is associated with bone conduction hearing loss.

[Relevant factors of tinnitus in the elderly: an analysis of 150 volunteers]

Objective:To evaluate and characterize tinnitus in elderly volunteers，try to find out the relevant factors that can affect the incidence of tinnitus.Method:The study included 150 elderly volunteers. All volunteers had taken the otology examination and pure tone audiometry. They were interviewed by the investigators who were trained together, using the same questionnaire. The characteristics of tinnitus and the relationship between all relevant factors and tinnitus were analyzed.Result:Average age was 71.4 years. There are now 77 patients with tinnitus(51.3%), of which 31 cases have sustained tinnitus for more than 3 months, accounting for 40.3% of existing tinnitus volunteers. There was negative correlation between tinnitus and age. There was positive correlation between tinnitus and hearing loss. Tinnitus and headache had no correlation(P>0.05).Conclusion:After reach a certain age(70 years old), the incidence of tinnitus decreased. Hearing loss might be the most dangerous factor.If the hearing loss was more serious, the incidence of the tinnitus became higher. Tinnitus in the elderly may be the result of a combination of factors.
