[Abstract]:Background: at present, short-tone ABR has been widely used in clinical practice, which provides an objective basis for the evaluation of hearing level and diagnosis of retrocochlear lesions. With the development of audiology. With the widespread development of neonatal hearing screening, it is found that more and more children with total deafness and / or extremely severe hearing loss are getting younger and younger. The improvement of hearing aid matching technology provides a glimmer of hope for children with residual hearing. But because short tone ABR reflects the level of 2000Hz~4000Hz, it can not meet the requirements of clinical audiology. In clinical practice, it is very important and urgent to obtain significant and effective residual hearing. Therefore, the study of frequency specific short tone ABR(tone burst ABRtb-ABR and CE-Chirp acoustic-evoked auditory steady-state evoked potentials (CE-Chirp ASSRs) has received great attention. Because they have the characteristics of objectivity, frequency specificity and high accuracy, they can be used in the diagnosis and evaluation of early hearing loss in infants and children. They can provide us with frequency specific wave V threshold of 500Hz~4000Hz. So it has been widely used at home and abroad [2-6]. In this paper, the results of short-tone ABR and CE-Chirp ASSR in 100 infants with extremely severe sensorineural hearing loss were analyzed, and their similarities and differences were observed in order to find out if the maximum output of ABR represented total deafness. Whether there is a threshold of reaction between their short-tone ABR and CE-Chirp ASSR at each frequency, [objective] to measure the short tone auditory brainstem response (burst auditory brainstem responsetb-ABR) and the auditory steady-state response induced by CE-Chirp (auditory steady-state responseCE-Chirp ASSRs) in 100 infants with extremely severe sensorineural hearing loss. The results of each frequency response threshold were summarized and analyzed, and the similarities and differences between the two methods were compared. [methods] 100 infants with extremely severe sensorineural hearing loss were tested with short-tone ABR and CE-Chirp ASSR frequency response thresholds. The reaction thresholds of 0.5 kW 1.0 kg 2.0 k and 4.0kHz were recorded, respectively. The data were tested by SPSS 11.0 statistical software for correlation test and X2 test. [results] the percentage of threshold of short tone ABR and CE-Chirp ASSR can lead to different degrees of threshold / V wave extraction mainly in 91-100dBHL5004000Hz threshold rate. The correlation coefficients between them were 0. 852U 0. 9110. 8700. 910. the chi-square test P value of all P values of 0.001.CE-Chirp ASSR and short tone ABR was 0. 05. [conclusion] short tone ABR suggests very severe hearing loss in infants and young children with sensorineural hearing loss, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, respectively. The frequencies of short tone ABR and CE-Chirp ASSR had different degrees of residual hearing. There was a good correlation between short tone ABR and CE-Chirp ASSR. There was no significant difference among different ears.
