Modified Method

Objectives to improve the quality of hearing aids (HA) selection for patients with sensorineural hearing loss using a comparative free sound field speech audiometry according to our modified method "Delta Test". Material and methods. The study involved 56 patients aged from 18 to 62 years with bilateral chronic sensorineural hearing loss of 2-4 degrees. The study group included 32 patients, a test for speech recognition in a free sound field (speech audiometry) was conducted using the method proposed by us. The control group consisted of 24 patients who were aided without the use of comparative speech audiometry. The "Delta Test" included the use of audio files sets containing a speech material in pure form and mixed with speech noise with different signal-to-noise ratios, supplied through a speaker system connected to a personal computer. The percentage of correctly repeated words was measured without HA and with several HA having different settings. The effectiveness of using HA was defined as the difference in the percentage of speech recognition when using HA in relation to the "ear without HA". Results. According to "The International Outcome Inventory for Hearing Aids" the average score was 4.13 0.10 in the group where the HA were selected using the "Delta Test", which is statistically significantly higher than in the control group, where the average score was 3.720.15(p 0.05). "Delta Test" allows optimally select the HA parameters. This method is easy to perform and does not require expensive equipment.

Objective The efficacy of the Otologics Fully Implantable Hearing Device (MET) was assessed in adult patients with bilateral moderate to severe sensorineural hearing loss. Methods Surgical insertion of this totally implanted system was identical to the Phase I study. A repeated-measures within-subjects design assessed aided sound field thresholds and speech performances with the subject's own, appropriately fit, walk-in hearing aid(s) and the Otologics Fully Implantable Hearing Device. Results Six- and 12-month Phase II data will be presented. Ten patients were implanted and activated as part Phase II clinical trial. Three patients were lost to long term follow-up due to two coil failures and one ossicular abnormality preventing proper device placement. No significant differences between preoperative (AC = 59 dB, BC = 55 dB) and postoperative (AC = 61 dB, BC = 54 dB) unaided pure tone averages were noted (p < 0.05). Pure tone average implant aided thresholds (41 dB) were equivalent to that of walk-in-aided (37 dB) condition with no significant difference (p < 0.05) between patients’ walk-in-aided individual frequency thresholds and implant-aided thresholds. Word recognition scores and hearing in noise scores were similar between the walk-in-aided and for the implant-aided condition. Patient benefit scales will be presented at all end points. Conclusions Results of the Otologics MET Fully Implantable Hearing Device Phase II trial provide evidence that this fully implantable device is a viable alternative to currently available hearing aids in patients with sensorineural hearing loss.

Clinical Trial Results

OBJECTIVES: The safety of the Otologics Fully-Implantable MET Ossicular Stimulator was assessed in adult patients with bilateral moderate to severe sensorineural hearing loss. METHODS: Surgical implantation of the ossicular stimulator was performed. A repeated-measure, within-subjects design assessed safety and aided sound field thresholds and speech performances with the subject's own, appropriately fitted, walk-in hearing aid(s) and the Otologics Fully-Implantable MET Ossicular Stimulator. RESULTS: Twenty patients were implanted and activated as part of the Phase I clinical trial. Results demonstrated 10–20 dB of functional gain across audiometric frequencies. Pure tone averages and monaural word recognition scores were slightly better for the walk-in—aided condition, while patient benefit scales favored the postoperative implant-aided conditions. CONCLUSION/SIGNIFICANCE: Although monaural word scores and aided thresholds favored the walk-in—aided condition, preliminary results indicate that the Otologics MET Fully-Implantable Ossicular Stimulator is an alternative to currently available hearing aids in patients with sensorineural hearing loss.

The Impact

Relevance: Any kind of the hearing loss, especially in the childhood, affects the mental and intellectual development negatively as well as behavior and social position of a deaf patient in the hearing world. Cochlear implantation is the most effective and reliable method of medical and educational auditory-speech rehabilitation for both adults and children with severe hearing loss and deafness. One of the key performance indicators of the cochlear implantation is a result of speech audiometry, especially on the noise background. The aim is to study the state of auditory function according to the subjective audiometry in the noise background and the influence of various factors on the effectiveness of rehabilitation of the children after cochlear implantation. Materials and methods: The study involved 150 children with severe sensorineural hearing loss and deafness after cochlear implantation. In age, they ranged from 3 to 18 years old. Evaluation of the efficiency of cochlear implantation was carried out in several stages. All studies were done in the free-field with the cochlear implant on. At first, we performed the pure tone audiometry. Then we defined the 50% intelligibility threshold of numeral test. After that, we defined a word recognition percentage. And finally we defined the impact of masker on speech intelligibility at SPL of useful signal 50, 60 and 80 dB. Results: Based on the analysis of the received data, all children with severe sensorineural hearing loss and deafness after cochlear implantation were divided into 3 groups depending on the speech intelligibility. The first group (high efficiency of cochlear implantation) included 68 children (45,3%). This group was divided into two subgroups depending on the difference between the values of the speech intelligibility in the free sound field and in the noise background. The second group (average efficiency) consisted of 45 children (30%). The third group (low efficiency) were 37 children (24,7%). The influence of various factors on the efficiency of cochlear implantation was analyzed. Conclusion: Speech intelligibility in the noise background must be examinated in all children after cochlear implantation. The main factors affecting the effectiveness of cochlear implantation according to test of speech intelligibility in the noise background are the ethiology of hearing loss and duration of post-operation period. Results of speech intelligibility in the noise background test will help specialists who practice the rehabilitation of children after cochlear implantation (teachers for deaf, speech therapists) to pay attention to the decrease of speech intelligibility in children in the real conditions of communication and to focus their efforts on its improving with the appropriate methods.

Deterioration in speech intelligibility, the most common complaint of people with hearing loss, leads to social isolation and dramatically reduces the quality of life. The correction of peripheral hearing loss by hearing aid fitting does not always solve this problem in patients with chronic sensorineural hearing loss (SNHL). That is why in the process of audiological examination of patients with complaints of hearing loss, it is necessary to include methods of speech audiometry, which make it possible to comprehensively assess the functioning of the auditory system. The aim of the study: assessment of speech intelligibility in patients of different ages with SNHL. 94 people from 20 to 74 years of age were examined: 54 patients with SNHL (14 young and 40 elderly) and 40 people with normal hearing thresholds (20 young and 20 elderly). Besides the standard audiological examination, speech audiometry testing was conducted: evaluation of monosyllabic words intelligibility in quiet, binaural rapidly alternating speech test, dichotic digits test, Russian matrix sentence test (RuMatrix). Results: Speech intelligibility in elderly patients with SNHL was shown to be significantly worse than in young patients with a similar degree of hearing loss. The RuMatrix test in noise was proved to be the most sensitive test for comprehensive evaluation of the hearing system functioning.

Volume Doubling

Progressive sensorineural hearing loss is the most important early symptom of a cerebellopontine angle process. A case report is presented of a 42-year-old woman who was referred to our department in 1979. Oil cistemography showed non filling of the left internal acoustic canal. Audiometry was planned as the method of control, but she did not return until nine- years later. In 1988, an acoustic neurionoma of 4 cm diameter was found in the left CPA. Pure tone audiometry and speech audiometry showed that during the nine-year interval, her 60 dB flat sensorineural hearing loss and speech perception thresholds had remained almost unchanged. A follow-up with only tone and speech audiometry can lead to a false negative diagnosis in some of these cases. Calculation of the growth in tumour volume over nine years in this patient showed a tumour volume doubling time of about 15 months.

AbstractObjectivesTo evaluate the plasma levels of endothelial cell-specific molecule-1 (ESM-1) and pentraxin-3 (PTX-3) in patients with idiopathic sudden sensorineural hearing loss, and to compare the pre- and post-treatment levels in patients responsive and non-responsive to therapy.MethodsThe study included 108 subjects: 51 with idiopathic sudden sensorineural hearing loss and 57 controls. For ESM-1 and PTX-3 analyses, blood samples were collected before and three months after treatment initiation in the idiopathic sudden sensorineural hearing loss group and once for the control group. Treatment response was evaluated three months after therapy initiation with pure tone audiometry, and the patients were divided into two groups: responsive and non-responsive to treatment.ResultsSerum ESM-1 levels were significantly higher in the idiopathic sudden sensorineural hearing loss group than the control group, whereas the difference was not significant for PTX-3. In the responsive and non-responsive groups, ESM-1 and PTX-3 levels were not statistically different before and after treatment.ConclusionTo our knowledge, this is the first study investigating plasma ESM-1 and PTX-3 levels in idiopathic sudden sensorineural hearing loss. Increased plasma ESM-1 levels may confirm endothelial dysfunction involvement in idiopathic sudden sensorineural hearing loss pathogenesis, which could be associated with vascular impairment.

The Relationship

Objectives. Calprotectin, a protein released by neutrophils, has been used in many studies as a biomarker showing the presence of inflammation. In this study, it was aimed to investigate the relationship between serum calprotectin level and response to the treatment of idiopathic sudden sensorineural hearing loss (ISSHL).Methods. The present study is a prospective, cross-sectional historical cohort study. The study group consisted of 44 patients with ISSHL, and the control group consisted of 41 healthy volunteers without ear pathology. At the same time, patients in the study group were divided into three groups according to the response to ISSHL treatment (recovered, partially recovered, unrecovered). The relationship between the groups was statistically evaluated in terms of serum calprotectin levels.Results. The mean serum calprotectin value was 75.67±19.48 ng/mL in the study group and 50.24±29.14 ng/mL in the control group (<i>P</i>=0.001). Serum calprotectin value according to the severity of hearing loss in the mild, moderate and severe was 66.20±8.82, 70.35±16.77, and 91.23±19.73 ng/mL, respectively. Serum calprotectin value in the severe group was significantly higher compared to the moderate and mild groups (<i>P</i>=0.004, <i>P</i>=0.001, respectively). Serum calprotectin value according to the treatment response in the recovered, partially recovered and unrecovered groups was 63.36±11.54, 80.17±12.06, and 85.33±22.33 ng/mL, respectively. Serum calprotectin value in the recovered group was significantly lower compared to the partially recovered and unrecovered groups (<i>P</i>=0.002, <i>P</i>=0.001, respectively).Conclusion. Serum calprotectin value informs the clinician about both the severity of hearing loss and the response to treatment. Hence, serum calprotectin can be used as an important biomarker in ISSHL patients for the determination of the prognosis of disease.

Background: Brain functional alterations have been observed in children with congenital sensorineural hearing loss (CSNHL). The purpose of this study was to assess the alterations of regional homogeneity in children with CSNHL.Methods: Forty-five children with CSNHL and 20 healthy controls were enrolled into this study. Brain resting-state functional MRI (rs-fMRI) for regional homogeneity including the Kendall coefficient consistency (KCC-ReHo) and the coherence-based parameter (Cohe-ReHo) was analyzed and compared between the two groups, i.e., the CSNHL group and the healthy control group.Results: Compared to the healthy controls, children with CSNHL showed increased Cohe-ReHo values in left calcarine and decreased values in bilateral ventrolateral prefrontal cortex (VLPFC) and right dorsolateral prefrontal cortex (DLPFC). Children with CSNHL also had increased KCC-ReHo values in the left calcarine, cuneus, precentral gyrus, and right superior parietal lobule (SPL) and decreased values in the left VLPFC and right DLPFC. Correlations were detected between the ReHo values and age of the children with CSNHL. There were positive correlations between ReHo values in the pre-cuneus/pre-frontal cortex and age (p &lt; 0.05). There were negative correlations between ReHo values in bilateral temporal lobes, fusiform gyrus, parahippocampal gyrus and precentral gyrus, and age (p &lt; 0.05).Conclusion: Children with CSNHL had RoHo alterations in the auditory, visual, motor, and other related brain cortices as compared to the healthy controls with normal hearing. There were significant correlations between ReHo values and age in brain regions involved in information integration and processing. Our study showed promising data using rs-fMRI ReHo parameters to assess brain functional alterations in children with CSNHL.
