Vocal Audiometry in Hearing Aid Outcome Measurements

Single word repetition in quiet differs drastically from everyday conversation, raising validity issues when quality-of-life-type predictions are made starting from classic vocal audiometry. This report addresses the predictive power of metrics derived from traditional vocal audiometry in assessing real-life outcomes of hearing aid fittings. Correlation and regressions analyses on a dataset from 45 clients show that a weighted combination of metrics correlates reasonably well(R = 0.749, p = 0.016) with questionnaire data, explaining 56% of the variance

Screening methods for age-related hearing loss in older patients with cancer: A review of the literature

© 2018 by the authors. As people grow older, they may experience loss in hearing sensitivity. Age-related hearing loss may negatively affect the patient's quality of life as it may lead to social isolation. In older patients with cancer, hearing loss can seriously interfere with the patient's ability to deal properly with all aspects of their disease, and may have a cumulative effect on their already decreased quality of life. Therefore, the proper screening of those conditions is essential in order to optimise the patient's comfort during and after treatment. This review article aims at providing a concise image of the nature of age-related hearing loss, and provides an overview of the screening methods that could be used in older patients with cancer

Recovery from repeated sudden hearing loss in a patient with Takayasu’s arteritis treated with hyperbaric oxygen therapy: the first report in the literature

Hearing loss has been rarely reported in Takayasu's arteritis, presents as sudden sensorineural hearing loss and usually responds well to corticosteroid therapy. Hyperbaric Oxygen Therapy is commonly used as a supplementary treatment to corticosteroids for sudden hearing loss. We present the case of a woman with Takayasu's arteritis who had two episodes of hearing loss involving one ear at a time with a 11-month delay between each episode. During the first episode, the patient was treated with high-dose intramuscular corticosteroids with a temporary improvement of auditory threshold, that deteriorated close to previous level 14 days after cessation of therapy. In the second episode, Hyperbaric Oxygen Therapy was associated to corticosteroids, with a significant, longer term improvement in both ears, including the one that had shown to be unresponsive to previous pharmacologic therapy. Oxygen therapy could have played a role in hearing restoration in this patient, as it could have acted synergically with corticosteroids amplifying their effect

A European perspective on auditory processing disorder-current knowledge and future research focus

Current notions of \u201chearing impairment,\u201d as reflected in clinical audiological practice, do not acknowledge the needs of individuals who have normal hearing pure tone sensitivity but who experience auditory processing difficulties in everyday life that are indexed by reduced performance in other more sophisticated audiometric tests such as speech audiometry in noise or complex non-speech sound perception. This disorder, defined as \u201cAuditory Processing Disorder\u201d (APD) or \u201cCentral Auditory Processing Disorder\u201d is classified in the current tenth version of the International Classification of diseases as H93.25 and in the forthcoming beta eleventh version. APDs may have detrimental effects on the affected individual, with low esteem, anxiety, and depression, and symptoms may remain into adulthood. These disorders may interfere with learning per se and with communication, social, emotional, and academic-work aspects of life. The objective of the present paper is to define a baseline European APD consensus formulated by experienced clinicians and researchers in this specific field of human auditory science. A secondary aim is to identify issues that future research needs to address in order to further clarify the nature of APD and thus assist in optimumdiagnosis and evidence-based management. This European consensus presents the main symptoms, conditions, and specific medical history elements that should lead to auditory processing evaluation. Consensus on definition of the disorder, optimum diagnostic pathway, and appropriate management are highlighted alongside a perspective on future research focus

Association between obstructive apnea syndrome during sleep and damages to anterior labyrinth: Our experience

The obstructive sleep apnea syndrome is a chronic condition characterized by frequent episodes of collapse of the upper airways during sleep. It can be considered a multisystem disease. Among the districts involved, even the auditory system was seen to be concerned. It was enrolled a population of 20 patients after polysomnographic diagnosis of OSAS (Apnea Hypopnea Index > 10) and a control group of 28 healthy persons (Apnea Hypopnea Index < 5). Each patient has been subjected to Pure Tone Audiometry, Tympanometry, study of Acoustic Reflex, Otoacoustic Emissions and Auditory Brainstem Response. Moreover they were submitted to endoscopy of upper airway with Muller Maneuver and Epworth Sleepiness Scale (ESS). The values of ESS was 13.5 in OSAS group and 5.4 in control group. The tone audiometry is worse in all frequencies analyzed in OSAS patients, but within the normal range for both groups analyzed by 250 to 1000 Hertz. Otoacoustic emissions show a reduced reproducibility and a lower signal/ noise ratio in OSAS group (P <0.01)

Progressive auditory neuropathy in patients with Leber's hereditary optic neuropathy

Objective: To investigate auditory neural involvement in patients with Leber's hereditary optic neuropathy (LHON).Methods: Auditory assessment was undertaken in two patients with LHON. One was a 45 year old woman with Harding disease (multiple-sclerosis-like illness and positive 11778mtDNA mutation) and mild auditory symptoms, whose auditory function was monitored over five years. The other was a 59 year old man with positive 11778mtDNA mutation, who presented with a long standing progressive bilateral hearing loss, moderate on one side and severe to profound on the other. Standard pure tone audiometry, tympanometry, stapedial reflex threshold measurements, stapedial reflex decay, otoacoustic emissions with olivo-cochlear suppression, auditory brain stem responses, and vestibular function tests were undertaken.Results: Both patients had good cochlear function, as judged by otoacoustic emissions ( intact outer hair cells) and normal stapedial reflexes ( intact inner hair cells). A brain stem lesion was excluded by negative findings on imaging, recordable stapedial reflex thresholds, and, in one of the patients, olivocochlear suppression of otoacoustic emissions. The deterioration of auditory function implied a progressive course in both cases. Vestibular function was unaffected.Conclusions: The findings are consistent with auditory neuropathy - a lesion of the cochlear nerve presenting with abnormal auditory brain stem responses and with normal inner hair cells and the cochlear nucleus (lower brain stem). The association of auditory neuropathy, or any other auditory dysfunction, with LHON has not been recognised previously. Further studies are necessary to establish whether this is a consistent finding

Simultaneous Contralateral Vestibular Schwannoma and Middle Ear Paraganglioma Tumor

To the best of our knowledge, only 2 cases of a simultaneous contralateral vestibular schwannoma (VS) and middle ear paraganglioma (MEP) have previously been reported in literature. We report the third case observed in a 43-year-old male, who presented with an 11-year history of right-sided hearing loss and a 1-year history of left-sided pulsatile tinnitus. A magnetic resonance imaging (MRI) showed a VS on the right side and computer tomography (CT) identified a Fisch type A1 paraganglioma on the left side. The VS was treated using a translabyrinthine approach and the MEP was kept under radiological observation for 1 year. Due to the growth of the MEP (Fisch type A2), it was treated with excision via a retroauricular approach. Our case was very challenging because there was a different and important pathology on each side, both carrying a risk of deafness as a consequence of the disease and/or the treatments

Hearing with a cochlear implant: from bionic to bimodal listening

Introduction: Currently, cochlear implantation (CI) is the standard procedure for bilateral severe hearing loss in both children and adults. However, a considerable number of hearing-impaired patients, who are candidates for CI, have residual hearing in the low-frequency range. In addition to the refinement of the surgical techniques by the application of the principles of soft surgery, the design of particular, atraumatic electrodes, which are thinner, shorter and more flexible, has contributed to electroacoustic stimulation (EAS). The use of these atraumatic electrodes has resulted in preservation of residual hearing in up to 90% of cases. Electroacoustic hearing is associated with potential advantages over pure electric hearing: better speech understanding in noise, and superior music appreciation and sound quality. In addition, patients with EAS have awareness of sound, even when not wearing their CI. Methods: In the Ghent University Hospital, 6 severely hearing-impaired adult patients with sufficient low-frequency hearing were implanted with atraumatic electrodes. In 5/6 recipients, a Cochlear® Hybrid-L24 implant was used, whereas 1/6 received a Cochlear® CI422 implant. Results: Low-frequency acoustic hearing has been preserved in 5/6 patients. Three out of 6 patients use electroacoustic amplification postoperatively; 2/7 are stimulated electrically for the mid- and high-frequency range and have residual low-frequency hearing without need of amplification; and 1/6 patients is exclusively stimulated electrically for the whole frequency range because of deterioration of preoperative low-frequency hearing thresholds. Conclusion: In candidates for CI, application of soft surgery principles and the use of atraumatic electrodes should be raised to a standard because of the medical advantages, irrespective of the presence of residual hearing. In case of residual hearing, additional benefit is obtained in terms of better speech understanding in noise and a higher level of listening comfort
