ABSTRACT Tried to find the relationship between tinnitus and each testing method, provided information for objective diagnosis and treatment for tinnitus patients with sensorineural hearing loss.
The characteristics of audiology tests, including pure tone audiometric, acoustic immittance, middle ear muscle reflexes, matching test, distortion products otoacoustic emission(DPOAE) were compared in 79 ears of 69 tinnitus patients with sensorineural hearing loss.
The RI positive rate was higher in Convergence curve in tinnitus patients of sensorineural hearing loss, with the rate being 51.3%. The detection rates of DPOAE were 15.2% in patients of sensorineural hearing loss tinnitus groups, which were significant lower than those in control group.
Psychoacoustic techniques can produce a useful amount of clinical data regarding tinnitus in different aspects, these data can help clinicians design needed based managements. DPOAE test is helpful for the diagnosis of lesions in some tinnitus patients.
