感音神经性聋患儿的听功能综合评估 总被引:1,自引:0,他引:1
目的探讨听力测试组合(ABR+ASSR+声场环境中的行为测听)在感音神经性聋患儿残余听力评估中的应用价值。方法48名(96耳)感音神经性聋患儿中能配合纯音测听的患儿19人(38耳)设为PTA组,进行纯音测听及ASSR检测;不能配合纯音测听的患儿29人(58耳)设为BA组,进行声场环境中的行为测听(behavior audiometry,BA)、ABR及ASSR检测。结果①PTA组0.5、1、2、4kHz各频率ASSR反应阈与纯音听阈显著相关(P〈0.01),各频率相关系数分别为0.75、0.76、0.76、0.83,建立本实验室的ASSR—PTA直线回归方程;②BA组23耳ABR无反应但仍可引出ASSR,而ASSR无反应耳ABR均未能引出;BA组29例患儿中ASSR检测反应较好耳(29耳)在0.5~4kHz四个频率上,ASSR可测得83个反应阈值,行为测听可测得89个反应阈值,综合ASSR和行为测听可以得到96个反应阈值。结论与单项听力测试方法相比,听力测试组合(行为测听+ABR+ASSR)能为更小年龄、听力损失更重的患儿进行残余听力的评估,同时能对双侧耳间听力差异、各频率的听力损失程度进行评估,为听力损失病变的定位判断提供参考。 相似文献

OBJECTIVE: To investigate the clinical usefulness of the dichotic single-frequency auditory steady-state response (ASSR) for estimation of behavioral thresholds in children with severe to profound congenital sensorineural hearing loss. DESIGN: A comparative experimental research design was selected to compare behavioral and ASSR thresholds for the sample. Behavioral pure-tone audiometry served as the criterion standard. SETTING: Hearing Clinic, Department of Communication Pathology, University of Pretoria, Pretoria, South Africa. PATIENTS: A referred sample of 10 patients (20 ears), 5 girls and 5 boys aged 10 to 15 years (mean age, 13 years 4 months), with severe to profound sensorineural hearing impairment. MAIN OUTCOME MEASURES: The difference, and correlation, between 160 pure-tone behavioral and ASSR thresholds at 0.5, 1, 2, and 4 kHz. RESULTS: Mean differences between ASSR and behavioral thresholds were 6 dB for 0.5 kHz and 4 dB for 1, 2, and 4 kHz, with standard deviations varying between 8 and 12 dB. No significant differences (P<.05) were observed between ASSR and behavioral thresholds, except at 0.5 kHz, and Pearson correlation coefficients varied between 0.58 and 0.74 across the evaluated frequencies, with best correlation at 1 kHz and worst at 0.5 kHz. CONCLUSIONS: The ASSR thresholds provided reliable estimations of behavioral thresholds for children with severe to profound hearing loss and indicated an increased sensitivity for more profound hearing loss. 相似文献

The auditory steady-state response (ASSR) has gained popularity as an alternative technique for objective audiometry but its
use in less severe degrees of hearing loss has been questioned. The aim of this study was to investigate the usefulness of
the ASSR in estimating moderate degrees of hearing loss. Seven subjects (12 ears) with moderate sensorineural hearing loss
between 15 and 18 years of age were enrolled in the study. Forty-eight behavioural and ASSR thresholds were obtained across
the frequencies of 0.5, 1, 2, and 4 kHz. ASSR thresholds were determined using a dichotic multiple frequency recording technique.
Mean threshold differences varied between 2 and 8 dB (±7–10 dB SD) across frequencies. The highest difference and variability
was recorded at 0.5 kHz. The frequencies 1–4 kHz also revealed significantly better correlations (0.74–0.88) compared to 0.5 kHz
(0.31). Comparing correlation coefficients for behavioural thresholds less than 60 and 60 dB and higher revealed a significant
difference. Eighty-six percent of ASSR thresholds corresponded within 5 dB of moderate to severe behavioural thresholds compared
to only 29% for mild to moderate thresholds in this study. The results confirm that the ASSR can reliably estimate behavioural
thresholds of 60 dB and higher, but due to increased variability, caution is recommended when estimating behavioural thresholds
of less than 60 dB, especially at 0.5 kHz. 相似文献

The main issue regarding pediatric audiology diagnosis is determining procedures to configure reliable results which can be used to predict frequency-specific hearing thresholds.AimTo investigate the correlation between auditory steady-state response (ASSR) with other tests in children with sensorineural hearing loss.MethodsProspective cross-sectional contemporary cohort study. Twenty-three children (ages 1 to 7; mean, 3 years old) were submitted to ASSR, behavioral audiometry, click audiometry brain stem response (ABR), tone burst ABR, and predicting hearing level from the acoustic reflex.Resultsthe correlation between behavioral thresholds and ASSR was (0.70- 0.93), for the ABR tone burst it was (0.73 -0.93), for the ABR click it was (0.83-0.89) only at 2k and 4 kHz. The match between the ASSR and the hearing threshold prediction rule was considered moderate.Conclusionthere was a significant correlation between the ASSR and audiometry, as well as between ABR click (2k and 4 kHz) and for the ABR tone burst. The acoustic reflex can be used to add information to diagnosis in children. 相似文献

The inclusion of the auditory steady-state response (ASSR) into test-batteries for objective audiometry has allowed for clinical
comparisons with the most widely used procedure, the auditory brainstem response (ABR). The current study describes ASSR and
ABR thresholds for a group of infants and young children with various types and degrees of hearing loss. A sample of 48 subjects
(23 female) with a mean age of 2.8 ± 1.9 years SD were assessed with a comprehensive test-battery and classified according
to type and degree of hearing loss. Thresholds were determined with a broadband click-evoked ABR and single frequency ASSR
evoked with continuous tones (0.25–4 kHz) amplitude modulated (67–95 Hz). Mean difference scores (±SD) between the ABR and
high frequency ASSR thresholds were 9.8 (±11), 3.6 (±12) and 10.5 (±12) dB at 1, 2 and 4 kHz, respectively. An ASSR mean threshold
for 2–4 and 1–4 kHz compared to the ABR threshold revealed an average difference of 7 (±9) and 7.9 (±8) dB, respectively.
The overall correlation between the ABR and ASSR thresholds was highest for the mean ASSR thresholds of 2–4 and 1–4 kHz (r = 0.92 for both conditions). Correlations between the ABR and individual ASSR frequencies were slightly less (0.82–0.86).
The average of the 2–4 kHz ASSR thresholds correlated best with the click-evoked ABR for all categories of hearing loss except
for the sensorineural hearing loss category for which the 1–4 kHz ASSR average was better correlated to ABR thresholds. Findings
demonstrate the reliability of verifying high frequency ASSR thresholds with a click-evoked ABR as an important cross-check
in infants for whom behavioural audiometry may not be possible. 相似文献

This paper presents preliminary results obtained with the use of the auditory steady-state response (ASSR) technique as part of a cochlear implant candidacy assessment protocol for infants. Fifteen infants (30 ears), between 10 and 60 months of age, with severe-to-profound hearing loss participated in the study. ASSR measurements were performed for 0.5, 1, 2 and 4 kHz at intensities up to 120–128 dB HL. The ASSR thresholds were obtained in 74% of the measurements, and exceeded the maximum auditory brainstem response (ABR) intensity output in 91% of cases and the maximum free-field behavioral intensity output in 84% of cases. Eighty-seven per cent of ASSR threshold measurements were measured at intensities of 100 dB HL or higher, and almost half (47%) were measured at intensities of 115 dB HL and higher. Preliminary results indicate that absent ABR and behavioral thresholds do not preclude the possibility of residual hearing, making the ASSR a primary source of information regarding profound levels of hearing loss. 相似文献
