Zabell Hearing Centre
At the Zabell Hearing Centre, patients are able to work with audiology professionals who are genuinely concerned about their hearing health. The Zabell Hearing Centre provides a wide range of hearing aids and products as well as specialty services to test for hearing loss and monitor the ear health of each patient. Each patient is paired with an experienced audiologist to get one-on-one care during each visit.
Hearing Products
The staff at Zabell Hearing Centre are authorized by the Canadian Ministry of Health to provide a full range of auditory products. From basic hearing aids to those that have all of the technological features currently available, the audiologists work with each patient to help with the selection of the right hearing aid for every situation. Patients may try out a behind-the-ear, in-canal or an in-the-ear hearing aid. Every hearing aid is custom-made for the patient in order to achieve a comfortable fit. Each member of the team participates in ongoing training and education for the management of hearing aid systems and software. This allows the staff to provide high-quality care to each patient.
Hearing Screenings
Hearing screenings are important to the health of every person. Anyone can experience hearing loss due to the use of certain medications, exposure to some bacterial and viral illnesses and exposure to loud noises. Children with speech delays sometimes have undiagnosed hearing problems. As people get older, their hearing often declines to the point where it is difficult to carry on a conversation, hear the television or talk on the phone. The hearing screenings provided by the audiologists at Zabell Hearing Centre are designed to detect hearing loss in people of any age. Before coming in for a hearing screening, patients can take a short quiz to determine if they are at risk for hearing loss. A hearing screening takes about 30 minutes and the results are ready during the same visit.
Professional Services
In addition to hearing loss screenings, the audiologists at Zabell Hearing Centre offer professional services such as management of tinnitus. They can also assist patients with an ear canal blockage that is caused by a buildup of cerumen, or ear wax. The audiologists also help patients who are active swimmers or who work in trades that involve regular exposure to loud noises, such as construction workers and airport luggage handlers. Patients can also come in for hearing aid cleanings and tune-ups.

Liquid-type Botulinum Toxin Type A in Adductor Spasmodic Dysphonia: A Prospective Pilot Study
Source:Journal of Voice
Author(s): Wonjae Cha, Jeon Yeob Jang, Soo-Geun Wang, Ji-Heon Kang, Min-Gyu Jo
ObjectivesBotulinum toxin (BTX) has been widely used to treat adductor spasmodic dysphonia (ADSD). Most commercially available forms of BTX require reconstitution before use, which may increase the risk of contamination and requires careful titration. Recently, a liquid-type BTX type A (BTX-A) has been developed, which should simplify the procedure and enhance its efficacy. Herein, we present a prospective pilot study to investigate the efficacy and safety of liquid-type BTX-A in the treatment of ADSD.MethodsTwenty-six consecutive liquid-type BTX-A injections were performed in 12 patients with ADSD. We included as a control group 34 consecutive patients with ADSD who had previously undergone 52 vocal fold injection procedures with freeze-dried–type BTX-A.ResultsAll patients in both groups had improvement of symptoms related to ADSD and period of normal voice. Most patients experienced breathiness, and the onset time, the peak response time, and the duration of breathiness were similar in both groups. The duration of effect (days) was 96.96 ± 18.91 and 77.38 ± 18.97 in the freeze-dried–type and the liquid-type groups, and the duration of benefit (days) was 80.02 ± 18.24 and 62.69 ± 19.73 in the freeze-dried–type and the liquid-type groups. To compare the efficacy between the freeze-dried–type and the liquid-type BTX-A, the sessions of the unilateral vocal fold injection were included and were categorized as group A (1 ~ 2 units BTX-A) and group B (2 ~ 3 units BTX-A), according to the dose per vocal fold. There was no significant difference of effect time between freeze-dried–type and liquid-type BTX-A groups. No adverse events related to BTX or vocal fold injection were reported.ConclusionsLiquid-type BTX-A is safe and effective for the treatment of spasmodic dysphonia. With the advantages of simple preparation, storage, and reuse and animal protein-free constituents, liquid-type BTX-A may be a good option in the treatment of spasmodic dysphonia.

Health-related Quality of Life as Studied by EORTC QLQ and Voice Handicap Index Among Various Patients With Laryngeal Disease
Source:Journal of Voice
Author(s): Tom Karlsen, Lorentz Sandvik, John-Helge Heimdal, Marianne Jensen Hjermstad, Anne Kari Hersvik Aarstad, Hans Jørgen Aarstad
ObjectivesPatients with voice-related disorders are often treated by a multidisciplinary team including assessment by patient-reported outcome measures. The present paper aims at documenting the importance of including general health-related quality of life (HRQoL) measures to clinical investigations.Study designThe participants (N = 80 larynx cancer, N = 32 recurrent palsy, N = 23 dysfunctional, N = 75 degenerative/inflammation, N = 19 various) were included consecutively at the laryngology clinic at Haukeland University Hospital. In addition, HRQoL data were included from one national group with laryngectomies (N = 105), one group with various patients formerly treated for head and neck squamous cell carcinoma (N = 96), and one population-based reference group (N = 1956).MethodObtained were the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ), the Voice Handicap Index (VHI), and the Eysenck Personality Inventory (EPI) neuroticism scores.ResultsBy analysis of variance, we have determined significant dependence of groups analyzing the sum global QoL/health index (F = 9.47; P < 0.001), the functional HRQoL sum score (F5,2373 = 7.14, P < 0.001), and the symptom sum HRQoL scores (F7,2381 = 8.13; P < 0.001). In particular, patients with recurrent palsy and laryngeal cancer had lowered HRQoL. At the index levels, in particular dyspnea scores, were scored depending on larynx disease group (F7,2288 = 24.4; P < 0.001). The VHI score correlated with the EORTC H&N35 “speech” index with a common variance of 52%. VHI scores correlated with level of neuroticism with 8% common variance (P < 0.001) and EORTC scores with 22% (P < 0.001).ConclusionIn particular, among patients with voice-related disease, those with recurrent palsy and laryngeal cancer had lower HRQoL. Furthermore, the HRQoL and VHI scores were inversely tied to neuroticism.

Abstract
CONCLUSION: Bone conduction implants are useful in patients with conductive and mixed hearing loss for whom conventional surgery or hearing aids are no longer an option. They may also be used in patients affected by single-sided deafness.
OBJECTIVES: To establish a consensus on the quality standards required for centers willing to create a bone conduction implant program.
METHOD: To ensure a consistently high level of service and to provide patients with the best possible solution the members of the HEARRING network have established a set of quality standards for bone conduction implants. These standards constitute a realistic minimum attainable by all implant clinics and should be employed alongside current best practice guidelines.
RESULTS: Fifteen items are thoroughly analyzed. They include team structure, accommodation and clinical facilities, selection criteria, evaluation process, complete preoperative and surgical information, postoperative fitting and assessment, follow-up, device failure, clinical management, transfer of care and patient complaints.

Identification of a second HOXA2 nonsense mutation in a family with autosomal dominant non-syndromic microtia and distinctive ear morphology.
Identification of a second HOXA2 nonsense mutation in a family with autosomal dominant non-syndromic microtia and distinctive ear morphology.
Clin Genet. 2016 Aug 9;
Authors: Piceci F, Morlino S, Castori M, Buffone E, De Luca A, Grammatico P, Guida V
Abstract
Microtia is a congenital defect affecting external ears, which appear smaller and sometimes malformed. Here we describe a five-generation family with isolated bilateral microtia segregating as an autosomal dominant trait. Similar features had been previously observed in an autosomal dominant family with non-syndromic microtia and hearing loss segregating with a HOXA2 nonsense variant. HOXA2 biallelic mutations were also described in an inbreed family with autosomal recessive microtia, hearing impairment and incomplete cleft palate. In our family, sequence analysis detected a heterozygous protein truncating nonsense variant [c.670G>T, p.(Glu224*)] segregating in all affected individuals and absent in public databases. Present study confirms the role of HOXA2 gene in dominant isolated microtia and contribute to further define the dysmorphogenetic effect of this gene on ear development.

Associations between parental hearing impairment and children's mental health: Results from the Nord-Trøndelag Health Study.
Soc Sci Med. 2015 Dec;147:252-60
Authors: Borren I, Tambs K, Gustavson K, Ask H, Engdahl B, Sundet JM
Abstract
BACKGROUND: Some previous studies indicate that parental hearing loss may have negative consequences in the parent-child relationship. However, most of these studies are qualitative or have apparent methodological shortcomings.
OBJECTIVE: This study is the first of its kind conducted in a large population-based sample with audiometrically measured hearing loss aimed at investigating the extent to which parental hearing loss affects adolescents' mental health.
METHODS: Questionnaires were administered to the adult (>19 years) and adolescent (age 13-19 years) population of Nord-Trøndelag county, Norway (1995-97), which collected information on mental and somatic health, including hearing loss. For adults participating in the study, pure tone audiometry tests were also administered. In total, 4047 fathers and 4785 mothers with self-reported hearing loss data were identified. The corresponding numbers with measured hearing loss data included 4079 fathers and 4861 mothers. The associations between the degrees of self-reported or measured parental hearing loss and the mental health of their adolescent, measured by Hopkins Symptom Check List (SCL) 5, were estimated using generalized estimating equations. After adjusting for several covariates, the mental health symptoms of adolescents were compared by parental hearing loss (i.e., with versus without hearing loss).
RESULTS: Adolescents whose mothers had severe measured or self-reported hearing loss had significantly worse mental health than their counterparts whose mothers did not have a hearing loss. No corresponding effects were found in the adolescents whose mothers had only a slight/moderate hearing loss, neither measured nor self-reported. Paternal slight/moderate self-reported hearing loss was associated with a small significant reduction of mental health in the adolescents, although attenuated when adjusting for paternal distress. No significant effects were detected in the adolescents whose fathers had measured hearing loss.
CONCLUSION: Severe maternal hearing loss is associated with significantly increased adolescent distress.

The effect of jugular bulb-vestibular aqueduct dehiscence on hearing and balance.
Acta Otolaryngol. 2015;135(11):1103-7
Authors: Li S, Shen N, Cheng Y, Sha Y, Wang Z
Abstract
CONCLUSION: This study suggests that jugular bulb-vestibular aqueduct dehiscence (JBVAD) does not affect the hearing or balance functions of the inner ear.
OBJECTIVES: Since JBVAD may cause impairment of the inner ear and induce hearing loss, tinnitus, and vertigo, this study was to investigate the effect of JBVAD on hearing and balance.
METHOD: Patients undergoing temporal bone computed tomography (TBCT) scans from May 2013 to December 2013 at a tertiary referral hospital were reviewed. The topographic relationship between the jugular bulb (JB) and the vestibular aqueduct was assessed. The findings were classified as normal when there was always a bony structure between the two structures and as dehiscent when the bony coverage separating the two structures was absent. Clinical data were collected via electronic records and clinical follow-up.
RESULTS: A total of 1313 out of 8325 patients were diagnosed with a HJB. Forty-six patients showed JBVAD. The prevalence of dehiscence was 0.6% in patients undergoing temporal bone CT scans and 3.5% in patients with HJB. Of the 46 patients with JBVAD, 23 (50%) had sensorineural hearing loss, three (6.5%) had tinnitus, and two (4.3%) had vertigo. The correlation between JBVAD and these clinical symptoms did not achieve statistical significance.

Localization of the Reflection Sources of Stimulus-Frequency Otoacoustic Emissions
Abstract
The generation of stimulus-frequency otoacoustic emission (SFOAE) residuals in humans is analyzed both theoretically and experimentally to investigate the relation between the frequency difference between the probe and the suppressor tone and the localization of the residual source. Experimental measurements of the SFOAE residual were performed using suppressors of increasing frequency to separate the otoacoustic response from the probe stimulus. From the response to the probe alone, the SFOAE response was also estimated, using spectral smoothing, and compared with the residuals obtained for different frequency suppressors. A nonlinear delayed-stiffness active cochlear model was used to compute the spatial distribution of the residual sources according to a recent model of the local reflectivity from roughness, as a function of the suppressor frequency. The simulations clarified the role of high-frequency suppressors, showing that in humans, with increasing suppressor frequency, the generation region of the residual is only slightly basally shifted with respect to the case of a near-frequency suppressor, near the basal edge of the peak of the resonant basilar membrane response. As a consequence, the hierarchy among different-delay components correspondingly changes, gradually favoring short-delay components, with increasing suppressor frequency. Good agreement between the experimental and theoretical dependence of the level of otoacoustic components of different delay on the frequency shift between probe and suppressor confirms the validity of this interpretation.
