Full textAcromegaly is a rare endocrine disease. Few studies have evaluated its association with hearing loss (HL) or disturbance in conduction of the auditory neural impulse. The results are conflicting. The aim is to evaluate central and peripheral auditory transmission in acromegalic patients. Besides, to evaluate the prevalence and characteristics of HL in patients with acromegaly. A cross-sectional study was carried out on 36 patients with acromegaly in a specialized ambulatory in Fortaleza-CearÃ. Patients with abnormal otoscopy, family history of hearing loss, use of ototoxic drugs or occupational noise exposure were excluded. Initially, the group was evaluated by pure tone audiometry. HL was considered when pure tone average was > 25 DBHL for low frequencies (250, 500, 1000 e 2000 Hz) or high frequencies (3000, 4000, 6000 e 8000 Hz). The whole group was divided in: acromegaly with HL (Acro HL) and without HL (AcroNHL) and compared in regards to hormonal levels and metabolic parameters. Additionally that group of patients with acromegaly was divided into 2 subgroups: with (n=16) and without (n=20) diabetes mellitus/impaired glucose tolerance (DM/IGT). The results were compared among these subgroups and a control group (n=20) regarding the brainstem auditory evoked potentials (BAEP) parameters.Kolmogorov-Smirnov test was used to evaluate the normality of distribution when necessary. Qui-quadrado, Student t test and Pearson correlation coefficient were carried out. The level of statistical significance chosen was at p<0.05 (statistical package for social sciences-SPSS 12.0). Among 36 patients evaluated, 14 (38,9%) showed sensorioneural HL (Acro HL), being 9 bilateral and 5 unilateral cases. No one had mixed or conductive HL. The prevalence of diabetes/impaired glucose tolerance was similar between the groups. The frequencies 250, 3000, 4000, 6000 and 8000 Hz were the most affected and with a similar pattern in both ears. The group with acromegaly showed a prolonged peak I latency in the right ear in comparison to the control group (p=0,007), with no difference regarding the interpeak intervals in any sides. This pattern was the same when comparing the DM/IGT subgroup to controls. Also, we found a prolonged peak I latency in the right ear in relation to the left ear in the group with acromegaly.In conclusion, a high prevalence of sensorineural HL was shown in patients with acromegaly. Nevertheless, no correlation was observed between this dysfunction and clinical or metabolic characteristics of the disease. Patients with acromegaly associated with DM/IGT showed a delayed neural impulse in the auditory nerve unilaterally in the right side, evidencing a non-homogenous neuropathic effect of the carbohydrate metabolism disturbances on the auditory nerve.

Full textOtitis media, a common affection in childhood, causes a fluctuating conductive hearing loss, because once treated the hearing thresholds back to normal values. Concern occurs when these episodes become recurring leading the child to receive an inconsistent sound stimulation auditory central nervous system, it difficult for the perception of speech sounds. The aim of this study was to investigate whether children with recurrent episodes of proven otitis media with effusion present alterations of auditory skills that composes the auditory processing. We evaluated 59 children with ages between 6 and 10 years, divided into two groups: the experimental group comprised of 29 children of both genders with documented history of otitis media with effusion, conductive hearing loss in the early years of life and with and without history of surgery for ventilation tube placement in preschool and school age; and the control group, consisting of 30 children, paired in age and gender with the experimental group, but no history of the disease. In the assessment of auditory skills that make up the auditory processing was used Speech in Noise Test (SNT), Dichotic Digits Test (DDT) and Gaps in Noise test (GIN). All children had at the time of assessment were free of conductive hearing loss. The results showed that: the two groups showed no differences in tonal thresholds, at the time of the assessment; the experimental group showed results below the SNT and GIN, both in qualitative and in quantitative analysis; DDT only in qualitative analysis differentiated the two groups. It can be concluded, with the results of the work, that children with a history of otitis media with effusion recurrent and persistent, pre-school and school phases, may have auditory processing disorder.

Full textIntroduction: Congenital aural atresia is a congenital deformity. It is unilaterally prevalent due to alterations in the development of the external and middle ear structures. Congenital aural atresia causes conductive hearing loss and can be accompanied by sensorineural component. Among the available forms of treatment is the middle ear implant, Vibrant Soundbridge (VSB), which has been shown to be effective in treating this type of alteration. The literature shows improvement in tonal thresholds and in the results of tests of auditory perception of speech that were performed using the speech processor after surgery. Individuals with this type of malformation often experience a period of auditory sensory deprivation prior to rehabilitation. Hence, it is important to evaluate the maturation stage of the cortical auditory structures, the processing of auditory information at the central level, and to verify the benefit of unilateral VSB in difficult listening situations. There are no previous data on this aspect and with the use of cortical auditory evoked potentials (CAEP) and event-related potential (P300) in users of VSB. Aim: To analyze the impact of conductive and mixed hearing loss on CAEP and P300 in unilateral VSB users with bilateral ear atresia. To verify the auditory abilities in a difficult listening situation considering the indication for unilateral VSB. Materials and methods: Twenty individuals were divided into two groups matched for age, sex, and educational level. G1 comprised ten individuals with bilateral conductive or mixed hearing loss and users of unilateral VSB, who visited the research institution. All subjects used conventional hearing aids prior to VSB. G2 comprised ten normal hearing individuals. Audiometry in the free field was performed with the use of VSB (G1 only) and evaluation of hearing skills by the Hearing in Noise Test was conducted; components P1, N1, P2, N2, and P300 in a calibrated field were recorded. Results: Evaluation of the mean tonal thresholds in the frequencies between 500 and 3000 Hz, from 20 to 36 dB HL, demonstrated that VSB allowed access to speech sounds. There was no statistically significant difference in the CAEP and P300 latency values between the two groups. A statistically significant difference was observed in the sentence recognition threshold and the signal-to-noise ratio between the groups, with best results presented by G2. Conclusion: Individuals with congenital aural atresia and bilateral conductive or mixed hearing loss may reach maturation of the central auditory pathway and achieve adequate processing of auditory information at the cortical level, when rehabilitated. The auditory recognition skills, with and without competitive noise, were shown to be out of phase with normality, indicating the need for a bilateral VSB

The purpose of this study was to evaluate the speech discrimination of patient with unilateral conductive hearing loss under quiet and noise environment. Taiwan Version of Mandarin Hearing in Noise Test (MHINT-T) was used to investigate the reception thresholds of sentences (RTS) in sound field. There were 42 individuals involved in this study. Twenty five individuals with normal hearing threshold were refer as control group, and the rest with unilateral conductive hearing loss were referred as test group. The study was to test the RTSs in each group under quiet and noise environment. In the control group, the average RTS in quiet was 22.5 dBA (SD = 2.54 dB). There were three different situations when testing under noise: noise front, noise right and noise left. In order to achieve 50% sentence discrimination score, noise front averaged signal to noise ratio was -6.9 dB (SD = 0.95 dB). Noise right was -15.7 dB (SD = 1.19 dB) and noise left was -12.6 dB (SD = 1.85 dB), respectively. Noise composite was -10.6 dB (SD = 0.95 dB), which represented the total performance under noise situation for individuals. In the test group, RTS in quiet was 29.9 dBA (SD = 3.54 dB). According to the thresholds from both ears of individuals, separated noise source into three direction: noise front, noise form bad side and noise from normal side. The averaged SNR of noise front was -5.7 dB (SD = 0.90 dB), -9.3 dB (SD = 2.44 dB) for the noise form bad side, and -5.7 dB (SD = 2.51 dB) for noise form normal side and noise composite was -6.6 dB (SD = 1.06 dB), respectively. There was a normal ear in patients who had unilateral conductive hearing loss, but their speech discrimination were worse than person who had normal hearing in all test situation. We should not ignored the speech discrimination under quiet and noise environment effected by mild or moderate hearing loss. Treatment would be suggested to elevate thresholds of the bad ear in order to improve speech discrimination under quiet and noise environment.

Full textABSTRACT: Introduction and goals: Bedside testing may accelerate clinical decision by making a quick qualitative assessment of hearing loss. This study described the design and validation of a bedside test with tuning forks that allow some quantitative evaluation of hearing loss in the presence of unilateral conductive hearing loss. Three distinct phases were considered: the first phase of the study quantified the effects of complete external auditory canal occlusion on hearing, in order to decide which tuning fork frequency is more appropriate to use for quantifying the hearing loss with the novel contralateral occlusion test (COT). The reproducibility of occlusion between examiners was also explored in this phase of the study. The second phase of the study evaluated the effects of external auditory canal occlusion on hearing thresholds with aging, in order to decide which tuning fork is more appropriate to use for the COT in individuals of different ages. The third phase of this study evaluated the accuracy of the test in predicting the degree of hearing loss. Methods: Over the study period, the three distinct phases considered population numbers of different age/size classes. At the first phase, 20 normal-hearing adults (40 ears) between 21-30 years old underwent sound field pure tone audiometry with and without ear canal occlusion. Each ear was tested with the standard frequencies (250, 500, 1000, and 2000 Hz) with warble tones. The contralateral ear was suppressed with the use of masking. Ear occlusion was performed by two examiners. In the second phase, 42 normal hearing subjects (84 ears) between 21 and 67 years were divided into three age groups (20–30 years, 40–50 years, and 60–70 years). Participants underwent sound field audiometry tests as described to the first phase of the study. In the third phase, 53 subjects with unilateral conductive hearing loss were recruited from an otolaryngology department of a tertiary hospital. The COT was performed to determine lateralization using 128, 256, 512, 1024 and 2048 Hz tuning forks with the non-affected ear meatus totally occluded. Pure-tone audiometry was then performed, separately and blinded of the tuning fork test results, to establish the presence and degree of the air-bone gap (ABG) and the pure-tone average (PTA). The tuning fork responses were finally correlated with the ABG and the PTA to determine their accuracy in quantifying the degree of hearing loss. Results: In the first phase of the study, occlusion of the external auditory canal determined an increase in hearing thresholds with increasing frequencies, from 19.94 dB (250 Hz) to 39.25 dB (2000 Hz). The difference on hearing thresholds between occluded and unoccluded conditions was statistically significant and increased from 10.69 dB (250 Hz) to 32.12 dB (2000 Hz). There were no statistically significant differences according to gender or between examiners. The second phase of the study demonstrated that hearing thresholds increased with higher frequencies from 20.85 dB (250 Hz, 20–30 years group) to 48 dB (2000 Hz, 60–70 years group). The difference on hearing thresholds between occluded and unoccluded conditions were statistically significant and increased, ranging from 11.1 dB (250 Hz, 20–30 years group) to 32 dB (2000 Hz, 20–30 years group). Statistically significant differences were found for the three age groups and for all evaluations except to 500 Hz difference and average difference. The mean hearing loss produced by occlusion at 500 Hz was approximately 19 dB. No statistically significant differences were found between right and left ears and gender for all measurements. In the third phase of the study COT showed a stronger association between hearing loss and the lateralization response using the 512 Hz tuning fork (p = 0.001). The sensitivity of the 512 Hz fork in detecting a PTA equal or greater than 35.6 dB was 94.6% and the specificity was 75.0% for a positive predictive value of 89.7% and a negative predictive value of 85.7%, assuming a pretest prevalence of 69.8%.Conclusions: The occlusion method as performed demonstrated reproducibility between examiners and with aging. The occlusion effect increased the hearing thresholds and became more evident with higher frequencies. The COT was accurate in predicting the degree of unilateral conductive hearing loss. If lateralization to the affected ear occurred, it was almost certain that the affected ear has a moderate or severe conductive hearing loss. 256 Hz or 512 Hz tuning forks were the more appropriate for diagnosis of mild hearing loss, and the 2048 Hz tuning fork was the more appropriate for moderate hearing loss; but aging and accuracy studies demonstrated that the use of the 512 Hz tuning fork is the most suitable for COT. The use of this test may allow clinicians to distinguish mild from moderate or greater than moderate unilateral conductive hearing loss.
