Abstract

Sixteen hydrocephalic NICU babies and 16 age-matched, non-hydrocephalic NICU babies were tested with BERA. The latency and amplitude of waves I and V were compared between groups. Both waves were longer in latency and smaller in amplitude in the hydrocephalic group. The I-V latency interval was within normal limits, but the V/I amplitude ratio was significantly smaller. The reduced amplitude of wave V was the most noticeable ABR abnormality. A total of 11 hydrocephalic babies showed responses that were considered abnormal in amplitude, with all but one having an elevated ABR threshold in at least one ear. These threshold elevations may reflect a neurological condition rather than a peripheral hearing loss.

Hearing threshold assessment post grommet insertion. Is it reliable?

We aimed to investigate whether auditory brainstem response (ABR), assessed immediately after grommet insertion, was an accurate measure of hearing threshold. Ten children were recruited (20 ears). Patients underwent transient evoked otoacoustic emission (TEOAE) and ABR tests before and after grommet insertion under general anaesthetic. A third assessment was conducted at a six-week review, without anaesthetic or sedation. The hearing threshold in dB and the presence of TEOAE were recorded by senior audiologists. The results of each investigation were compared. At review, only 15 ABR and 17 TEOAE tests, of a possible 20, were recorded. Transient evoked otoacoustic emissions were recorded in 30 per cent of ears pre-operatively, 20 per cent of ears post-operatively and 82 per cent of ears at six-week review. The average ABR thresholds were 23.75 dB (range 10-45 dB) pre-operatively, 27.25 (range 15-40 dB) post-operatively and 15 dB (range 5-25 dB) at six-week review. Comparing pre- and post-operative assessment, decreased thresholds were seen in six ears and elevated thresholds in 11. Comparing the six-week review ABR with the post-operative ABR, 13 ears had decreased thresholds, by as much as 20 dB. Thresholds of 35 dB or greater were measured in six ears immediately after grommet insertion (maximum 40 dB). Threshold shifts of 15 dB or greater was observed in seven ears. The intra-subject variation was shown to be significant (p<0.001) when repeated measures analysis of variance was applied. We conclude that there is evidence that ABR can be inaccurate after grommet insertion, overestimating hearing thresholds. We believe that the mechanism by which the error is realised is temporary threshold shift.

Diagnostics of the cochlear amplifier by means of distortion product otoacoustic emissions.

Distortion product otoacoustic emission (DPOAE) growth functions reflect the active nonlinear cochlear sound processing when using a primary-tone setting which accounts for the different compressions of the two primaries at the DPOAE generation site and hence provide a measure for objectively assessing cochlear sensitivity and compression. DPOAE thresholds can be derived from extrapolated DPOAE input/output (I/O) functions independently of the noise floor and consequently can serve as a unique measure for reading DPOAE measurements. The thus-estimated DPOAE thresholds exhibit a close correspondence to behavior audiometric thresholds and thus can be used for reconstructing an audiogram, i.e., a DPOAE audiogram. The DPOAE I/O functions' slope increases with cochlear hearing loss and thus provides a measure for assessing recruitment. Hence, DPOAE I/O functions can give more information for diagnostic purposes than those of DP grams, transiently evoked OAEs (TEOAEs), or auditory brain stem responses (ABRs). DPOAE audiograms can be applied in pediatric audiology to assess cochlear dysfunction in a couple of minutes. In newborn hearing screening, they are able to detect transitory sound-conductive hearing loss and thus can help to reduce the rate of false-positive TEOAE responses in the early postnatal period. Since DPOAE I/O functions are correlated with loudness functions, DPOAEs offer the possibility of basic hearing aid adjustments, especially in infants and children. Extrapolated DPOAE I/O functions provide a tool for a fast automated frequency-specific and quantitative evaluation of hearing loss.

Hearing loss in patients undergoing coronary artery bypass grafting with or without extracorporeal circulation.

BACKGROUND: Our aim was to investigate the differences in postoperative hearing thresholds in patients undergoing coronary artery bypass grafting with (Group I, n=20) or without (Group II, n=17) extracorporeal circulation. MATERIAL/METHODS: 37 patients undergoing coronary artery bypass grafting with or without extracorporeal circulation were prospectively evaluated in terms of hearing threshold changes with the intention of documenting hearing losses postoperatively. The t-test for two independent variables was used for statistical analysis. RESULTS: Hearing threshold changes were detected in 9 Group I patients (45%) and 3 Group II patients (17.65%). The difference between the two groups was statistically significant (p=0.0426). CONCLUSIONS: Postoperative hearing threshold changes, not necessarily revealed by clinical examinations, are encountered after coronary artery bypass grafting operations. Extracorporeal circulation usage seems to bring an additional risk in terms of hearing loss.
