The analysis of the brainstem auditory evoked potential BAEP made at birth showed a higher incidence of central alterations in the group with PIVH Table 1.
The most widely used andclinically recognized short latency potential is the Brainstem Auditory Evoked Potential BAEP, owing to its reproducibility and well-defined generators.
The brainstem auditory evoked potential BAEP has been considered the gold standard in the diagnosis of the integrity of auditory pathway in neonates at risk of hearing impairment.
For an early identification of deafness,the use of objective measures such as recording evoked otoacoustic emissions and brainstem auditory evoked potential BAEP is recommended.
Click stimuli were used for the brainstem auditory evoked potential BAEP, monoaurally presented at 80dBHL, with a rarefaction polarity and at a rate of 19.1 clicks/second.
Diagnosis is conducted through audiometric and electrophysiological tests, andis confirmed by the presence of otoacoustic emissions OAE associated to altered or absent brainstem auditory evoked potential BAEP.
The Brainstem Auditory Evoked Potential BAEP is considered the"gold standard" test in the diagnosis of the integrity of auditory nerve and pathways of the central nervous system in neonates.
Only animals with distortion product otoacoustic emissions DPOAEs andelectrophysiological hearing thresholds of 25 dB estimated by brainstem auditory evoked potential BAEP were included in the study.
Brainstem auditory evoked potential BAEP, middle-latency auditory evoked potential MLAEP, and P300 tests were conducted at the CDP at FMUSP.
The first stage of the study consisted of an analysis of transient evoked otoacoustic emissions TEOE and brainstem auditory evoked potential BAEP performed in 84 preterm infants in the predischarge.
The brainstem auditory evoked potential BAEP is an objective electrophysiological method for assessing the auditory pathways from the auditory nerve to the brainstem. .
The audiological tests performed were: impedance audiometry, otoacoustic emissions,play audiometry, Visual Reinforcement Audiometry VRA, and Brainstem Auditory Evoked Potential BAEP, according to the requirements of each case.
The brainstem auditory evoked potential BAEP consist of registering the electrical activity in the auditory system from the inner ear to the brainstem by presenting an acoustic stimulus.
If there is no improvement in the electrophysiological responses,they are referred to audiological diagnosis, which evaluates them through brainstem auditory evoked potential BAEP, audiometric tests with visual reinforcement, and assessment of middle ear status.
The Brainstem Auditory Evoked Potential BAEP evaluates the electric activity of the ascending auditory pathway which resides all the way on the Brainstem BS segment responsible for the majority of the vital functions of the organism.
A difference was found between exposed andnon-exposed workers in the analysis parameters of Brainstem Auditory Evoked Potential BAEP and the Central Auditory Processing CAP tests Pitch Pattern Sequence PPS, Dichotic Digit DD and Hearing-In-Noise Test HINT; however.
To record brainstem auditory evoked potential BAEP, the rarefied polarity click acoustic stimulus was used, presented monaurally at 80 dBnHL, at a 19.1 stimuli per second display speed and a duration of 0.1 millisecond. A total of 2,000 stimuli were employed.
The ANSD is characterized by a classic clinical picture,evidenced by absence of significant alterations on the Brainstem Auditory Evoked Potential BAEP results, presence of Evoked Otoacoustic Emissions EOAE and/or cochlear microphonic CM, and absence of stapedial acoustic reflexes.
In 2000, the Brazilian Speech Therapy Council issued an opinion indicating the need to implement hearing screening procedures in neonates using some objective methodology already described in the literature,such as recording evoked otoacoustic emissions and brainstem auditory evoked potential BAEP.
The brainstem auditory evoked potential BAEP was first done in all subjects to verify brainstem integrity; this was done to avoid distortions in the ensuing results, given that dysfunctions in the peripheral auditory system or brainstem may compromise P300 results.
For this reason we developed an original protocol which yielded injury in three cochlear gyri,ratified by otoacoustic emission distortion product tests OAEDP, the brainstem auditory evoked potential BAEP and scanning electron microscopy EM; this protocol had a lower lethality rate.
The Brainstem Auditory Evoked Potential BAEP acts as an aid in the detection of sensorineural hearing loss of workers who operate in noisy places and are exposed to neurotoxic substances, because these substances reach the brainstem auditory pathways and not necessarily the hair cells.
Enrollment criteria: tone threshold audiometry, logoaudiometry, and impedance test results within normal values; absence of present andpast auditory complaints; brainstem auditory evoked potential BAEP within normal range and altered results in at least two central auditory processing behavior assessment tests.
In the present literature review, the brainstem auditory evoked potential BAEP was considered a procedure of significant sensitivity both for the identification of alterations in the central auditory pathway and for monitoring the evolution of the illness, regardless of the occurrence of hearing loss in HIV/AIDS patients.
The assessed patients were all submitted to tonal and vocal or behavioral audiometry, performed by the same qualified audiologist from this service,including otoacoustic emissions OAEs test and brainstem auditory evoked potential BAEP test carried out by experts in otolaryngology, computed tomography CT, and magnetic resonance imaging MRI of the mastoids and auditory pathways.
The Brainstem Auditory Evoked Potential BAEP is an objective, non-invasive, short latency exam that assesses the electrophysiological activity of an auditory system as far as the brainstem, in response to an acoustic stimulus characterized by a rapid, short-duration burst, eliciting bioelectric responses that result from the successive activation of the cochlea and nerve fibers of this pathway.
Nevertheless, there are other electrophysiologic procedures that can be included in the audiology process to enhance the diagnostics,e.g., brainstem auditory evoked potential BAEP and auditory steady state response ASSR, which can measure the auditory electrophysiologic hearing thresholds, as well as visualize the audiometric configuration.
Several researchers have studied 226 Hz and 1 kHz tympanometry in neonates and infants, and have characterized the different types of tympanometric curves for these probe tones.They have also sought to establish correlations with the results obtained in the Otoacoustic Emissions OAE and the Brainstem Auditory Evoked Potential BAEP, as well as to analyze the differences related to gender and ears.
