Abstract
Objective:To investigate the effects of age and involved semicircular canals on the results of caloric test in patients with primary horizontal semicircular canal benign paroxysmal positional vertigo(BPPV). Methods:A total of 258 patients conforming to the diagnosis of primary horizontal semicircular canal BPPV were selected as the case group, and another 110 non-BPPV patients with dizziness/vertigo as the main complaint were selected as the control group. Both groups were divided into elderly group and young and middle-aged group according to their age, and the general information and the results of the caloric test were compared and analyzed for each group. Results: ①There was no statistically significant difference in gender composition and type of involved semicircular canal between the different age groups(P>0.05);②In patients with horizontal semicircular canal canalolithiasis, there was no statistically significant difference in the rate of abnormal caloric test results between the different age groups(P>0.05);③In patients with horizontal semicircular canal cupulolithiasis, there was a statistically significant difference in the rate of abnormal caloric test results between the different age groups(P<0.05);④In the same age group, there was no statistically significant difference in the rate of abnormal caloric test results between the patients with horizontal semicircular canal canalolithiasis and the patients with cupulolithiasis(P>0.05);⑤In the control group, there was no statistically significant difference between the different age groups in gender composition(P>0.05);⑥In the control group, there was a statistically significant difference in the rate of abnormal caloric test results between the different age groups(P<0.05);⑦Among the patients in the same age group, there was no statistically significant difference in the age distribution between the case and control groups(P>0.05);⑧In patients of the same age group, there was no statistically significant difference in the rate of abnormal caloric test results between the case and control groups(P>0.05). Conclusion:The involvement of the semicircular canal does not affect the results of the caloric test, but age can affect the results, especially in BPPV patients with horizontal semicircular canal cupulolithiasis.

Abstract
Objective:To analyze the objective test results of the pure-tone audiogram (PTA), extended high-frequency audiometry (EHFA), distortion product otoacoustic emission (DPOAE), auditory brainstem response(ABR), and electrocochleogram (ECochG) in patients with unilateral acute tinnitus, summarize their characteristics and explore their clinical application value in hidden hearing loss. Methods:PTA, DPOAE, ABR, and ECochG tests were performed in 33 patients with unilateral acute tinnitus as the chief complaint. The detection rate and response amplitude of each DPOAE frequency, incubation period, and interval of ABR waves and -SP/AP in ECochG were analyzed. Results:①The thresholds of PTA at 0.25-8 kHz in both ears were in the normal range (P>0.05), and the thresholds of PTA at 9-16 kHz in affected ears were higher than those in healthy ears (P<0.001); ②There was statistical significance in the detection rate and response amplitude of DPOAE at 3, 4, 6, 8 kHz between ears (P<0.05); ③The incubation period of ABR Ⅰ wave in affected ears was (1.55±0.17) ms, that in the healthy ear was (1.50±0.14) ms, among them, the incubation period of ABR Ⅰ wave in the affected ear was longer than that in the healthy ear, and the difference was statistically significant (P<0.05); ④In ECochG, there was no significant difference in -SP amplitude between ears (P>0.05), but there was a significant difference in AP amplitude and -SP/AP amplitude between ears (P<0.05). Conclusion:EHFA, DPOAE, ABR, and ECochG have clinical significance in evaluating cochlear function in tinnitus patients.
