To compare the diagnostic accuracy of angled otoendoscopy with pure tone audiometry in predicting ossicular discontinuity in patients of mucosal chronic otitis media.
Methods
Ninety-four patients were included in this prospective study. A 2.7-mm 30° otoendoscope was used to examine ossicular status preoperatively. Hearing thresholds were recorded by pure tone audiometry. Intraoperative ossicular status was recorded as the gold standard. Otoendoscopic findings were recorded as per the criteria has been devised by the authors of this manuscript.
Results
Otoendoscopy was conclusive in 56 (59.6 per cent) patients, with 100 per cent sensitivity, 95.56 per cent specificity, 84.62 per cent positive predictive value, and 100 per cent negative predictive value in the conclusive group. Overall (in 94 patients), diagnostic test values of otoendoscopy were 73.33 per cent sensitivity, 97.47 per cent specificity, 84.62 per cent positive predictive value, and 95.06 per cent negative predictive value. As per the ROC curve, air–bone gap > 38.12dB had the optimal diagnostic test values, with 73 per cent sensitivity, 72 per cent specificity, 33.3 per cent positive predictive value, and 93.4 per cent negative predictive value.
Conclusion
Angled otoendoscopy has better diagnostic accuracy (93.6 per cent) than pure tone audiometry (72.3 per cent; p < 0.001) for preoperative ossicular discontinuity prediction in patients of mucosal chronic otitis media.
This study aimed to compare the peripheral-to-central auditory systems of people with coronavirus disease 2019 to a well-matched control group and examine the long-term effects of coronavirus disease 2019 on the auditory system.
Method
Participants who were outpatients of coronavirus disease 2019 (n = 30) were compared with a well-matched control group (n = 30). Behavioural and electrophysiological tests were performed, and tests were repeated at six months in the coronavirus disease 2019 group.
Results
Statistically significant differences were observed in the right ear at 10 kHz (p = 0.007) and 12.5 kHz (p = 0.028), and in the left ear at 10 kHz (p = 0.040) and 12.5 kHz (p = 0.040) between groups. The groups had no difference regarding the other audiological test results (p > 0.05).
Conclusion
Extended high-frequency thresholds were affected in the coronavirus disease 2019 patients. No other findings indicated that the peripheral-to-central auditory system was affected. The effect on extended high-frequency thresholds appeared permanent, but no clinically significant new, late-onset auditory system effects were observed.
Bone conduction hearing implants are a well-established method of hearing rehabilitation in children and adults. This study aimed to review any changes in provision in England.
Methods
The total number of bone conduction hearing implantations performed was analysed from 2012 to 2021 utilising Hospital Episode Statistics data for England.
Results
The total number of procedures has increased by 58 per cent. One-stage bone conduction hearing implantations in adults accounts for the largest proportion of this increase (93 per cent of the total). The number performed in children has remained stable and accounts for 73 per cent (n = 433) of all two-stage procedures.
Conclusion
The data show that bone conduction hearing implant surgery is becoming increasingly popular, particularly in adults. This has correlated with the increase in availability, national recommendations and choice of devices.
Using Otoplan software, it is possible to measure the cochlea before cochlear implant surgery. Until now, computed tomography (CT) of the cochlea has been necessary for this purpose. The aim of this study was to find out whether measuring the cochlea with magnetic resonance imaging (MRI) using Otoplan is possible with the same accuracy.
Methods
The cochlea of 44 patients of the local cochlear implant centre was measured by Otoplan using high-resolution CT-bone and MRI images, and the determined lengths were compared.
Results
No significant difference was found between the cochlear lengths measured, regardless of whether the length measurement was based on a CT or an MRI data set.
Conclusion
For the determination of cochlear length prior to cochlear implant surgery, MRI images are just as suitable as CT images, therefore CT is not mandatory for length measurement by Otoplan, which could reduce the patient's radiation exposure.
Cocaine is one of the most used recreational drugs. Whilst medical uses exist, chronic recreational nasal use of cocaine is associated with progressive destruction of the osseocartilaginous structures of the nose, sinuses and palate – termed cocaine-induced midline destructive lesions.
Case report
A 43-year-old male with a history of chronic cocaine use, presented with conductive hearing loss and unilateral middle-ear effusion. Examination under anaesthesia revealed a completely stenosed left Eustachian tube orifice with intra-nasal adhesions. The adhesions were divided and the hearing loss was treated conservatively with hearing aids. Whilst intra-nasal cocaine-induced midline destructive lesions are a well-described condition, this is the first known report of Eustachian tube stenosis associated with cocaine use.
Conclusion
This unique report highlights the importance of thorough history-taking, rhinological and otological examination, and audiometric testing when assessing patients with a history of chronic cocaine use. This paper demonstrates the complexity of managing hearing loss in such cases, with multiple conservative and surgical options available.
Hearing loss and tinnitus have been proposed as potential indicators of impaired mental health and brain morphological changes.
Aims
To assess the associations of hearing loss and tinnitus with the risk of depression and anxiety and with brain volume.
Method
We conducted a community-based cohort study including 129 610 participants aged 40−69 years at recruitment to the UK Biobank with a follow-up period during 2006–2021 to estimate the risk of depression and anxiety after detection of hearing loss and reported tinnitus. We also assessed the associations of hearing loss and tinnitus with brain volume in a subsample with available brain magnetic resonance imaging data (N = 5222).
Results
We observed an increased risk of depression among individuals with hearing loss (hazard ratio [HR] 1.14, 95% CI 1.03–1.26), tinnitus (HR 1.30, 95% CI 1.21–1.41) or both (HR 1.32, 95% CI 1.15–1.52), compared with individuals with neither hearing loss nor tinnitus. Similar results were noted for anxiety (HR 1.18, 95% CI 1.07–1.30 for hearing loss; HR 1.32, 95% CI 1.22–1.43 for tinnitus; and HR 1.48, 95% CI 1.30–1.68 for both). Hearing loss was associated with decreased overall brain volume as well as decreased volume of different brain regions. The latter associations disappeared after adjustment for whole intracranial volume. Tinnitus was associated with greater left accumbens and right occipital pole volume after adjustment for the whole intracranial volume.
Conclusions
Individuals with tinnitus are at increased risk of depression and anxiety. Hearing loss, on the other hand, is associated with both mood disorders and altered brain morphology.
This study aimed to evaluate the sensory processing abilities of adults with acquired hearing loss and determine whether their sensory processing patterns differ from those of the general population and adults with normal hearing.
Method
The study evaluated the sensory processing functions of 30 adults with acquired hearing loss using the Adolescent/Adult Sensory Profile and compared them with the sensory processing functions of 30 adults with normal hearing.
Results
The results showed that individuals with hearing loss have a significantly higher sensitivity to stimuli related to motion, vision, activity and touch, exhibiting a low-registration sensory pattern and a sensation-avoiding pattern that differed from those of most individuals.
Conclusion
Assessing sensory processing profiles can help identify specific sensory difficulties and inform individualised treatment plans. The study highlights the importance of considering sensory processing patterns in the management of hearing loss to improve overall well-being and quality of life for adults with hearing loss.
Sudden hearing loss is a common presentation to ENT. In the authors’ practice, patients often wait many weeks for formal hearing testing. This study aimed to assess whether a tablet-based hearing test, hearTest, could aid clinical decision-making within secondary care ENT.
Method
This was a multi-centre, prospective, non-randomised study to assess the feasibility, usability and accuracy of hearTest.
Results
In the sample, hearTest was shown to be an acceptable method of testing for hearing loss by both patients and clinicians. The 0.5–4 kHz range had an average clinical agreement rate of 95.1 per cent when compared with formal pure tone audiometry, deeming it an accurate test to diagnose hearing loss.
Conclusion
The authors propose that hearTest can be used within ENT as a clinical decision support tool when manual audiometry is not immediately available. Within the authors’ practice, hearTest is used to aid diagnosis and management of sudden sensorineural hearing loss.
This study aims to explore the association between coffee consumption and the prevalence of hearing loss in American adults based on a national population-based survey.
Design:
Cross-sectional analysis of reported audiometric status and coffee intake from the 2003–2006 National Health and Nutrition Examination Survey (NHANES). Multivariate logistic regression, forest plots and restricted cubic spline (RCS) analyses were used to explore the associations and dose–response relationships between coffee consumption frequency and hearing loss.
Setting:
The USA.
Participant:
This study included 1894 individuals aged ≥ 20 from the 2003–2006 NHANES.
Results:
In this study, the prevalence of speech-frequency hearing loss (SFHL) and high-frequency hearing loss (HFHL) among the participants was 35·90 % and 51·54 %, respectively. Compared with those who no consumed coffee, non-Hispanic White who consumed ≥ 4 cups/d had higher prevalence of SFHL (OR: 1·87; 95 % CI: 1·003. 3·47). And a positive trend of coffee consumption frequency with the prevalence of HFHL was found (Ptrend = 0·001). This association of HFHL was similar for participants aged 20–64 (Ptrend = 0·001), non-Hispanic White (Ptrend = 0·002), non-noise exposure participants (Ptrend = 0·03) and noise-exposed participants (Ptrend = 0·003). The forest plots analysis found that the association between 1 cup-increment of daily coffee consumption and the prevalence of HFHL was statistically significant in males. RCS model supported a positive linear association of coffee consumption with SFHL (P for overall association = 0·02, P for nonlinearity = 0·48) and a positive non-linear association of coffee consumption with HFHL (P for overall association = 0·001, P for nonlinearity = 0·001).
Conclusion:
Our findings suggested that coffee consumption was associated with higher prevalence of hearing loss. Further cohort studies in larger population are needed to investigate these findings.
In this chapter, we focus on language development in individuals suffering from language and cognitive disorders. One of the major concerns of families and caregivers of individuals with these disorders is that exposure to more than one language may cause further difficulties, slow down, or hinder linguistic and cognitive development. Scientific research, however, shows that this is an unmotivated prejudice, and that bilingualism does not provide negative effects, but rather, can offer benefits. We explore the interaction between bilingualism and language disorders, discussing in particular developmental language disorders, developmental dyslexia, autism spectrum disorders, hearing loss, Down syndrome, and aphasia.
One still encounters opinion that hearing loss with high-pitch notched audiogram is invariably due to noise-induced hearing loss. This paper tests this misapprehension.
Methods
A study was conducted of patients identified in a prospective manner with notched audiograms but no history of noise exposure occurring in an otolaryngological practice over a 20-year period.
Results
A cohort of 26 hearing loss patients, in whom notched audiograms were not associated with historical evidence of noise exposure, was documented.
Conclusion
The findings confirm that a notched audiogram is not pathognomonic of noise-induced hearing loss.
This study aimed to compare the pre- and post-operative vestibular and equilibrium functions of patients with cholesteatoma-induced labyrinthine fistulas who underwent different management methods.
Methods
Data from 49 patients with cholesteatoma-induced labyrinthine fistulas who underwent one of three surgical procedures were retrospectively analysed. The three management options were fistula repair, obliteration and canal occlusion.
Results
Patients underwent fistula repair (n = 8), canal occlusion (n = 18) or obliteration procedures (n = 23). Patients in the fistula repair and canal occlusion groups suffered from post-operative vertigo and imbalance, which persisted for longer than in those in the obliteration group. Despite receiving different management strategies, all patients achieved complete recovery of equilibrium functions through persistent efforts in rehabilitation exercises.
Conclusion
Complete removal of the cholesteatoma matrix overlying the fistula is reliable for preventing iatrogenic hearing deterioration due to unremitting labyrinthitis. Thus, among the three fistula treatments, obliteration is the optimal method for preserving post-operative vestibular functions.
This study evaluated audiological outcomes of stapedotomy using two different techniques, vein graft interposition and vein graft surround, for sealing the stapes fenestra.
Method
A retrospective study of 130 patients who underwent stapedotomy for otosclerosis was performed. A total of 84 patients underwent the vein graft surround procedure and 46 underwent the vein graft interposition procedure. Post-operative hearing outcome was compared between them.
Results
A total of 55 of 130 patients had a post-operative air–bone gap of less than 10 dB. A total of 57 patients had an air–bone gap within 20 dB. The average air–bone gap was 13.16 dB at 3 months with a mean improvement of 22.06 dB (11.98 dB for vein graft interposition and 13.80 dB for vein graft surround; p = 0.79).
Conclusion
There was no significant difference in hearing outcome between the two techniques. The vein graft interposition technique is preferred for large fenestra or stapedectomy cases and in cerebrospinal fluid gusher cases. The vein graft surround technique is easier to perform and preferred in small fenestra stapedotomy.
This study investigated the frequency of ear canal protection use and looked at its influence on external auditory exostosis severity and knowledge about external auditory exostosis among windsurfers and kitesurfers on the German coast.
Method
This retrospective cross-sectional study interviewed 130 windsurfers and kitesurfers along the German coast on knowledge of external auditory exostosis, exposure time, use of neoprene hoods and earplugs, and otological complaints. Participants underwent bilateral video-otoscopic examination.
Results
Knowledge of external auditory exostosis was ‘good’ or ‘excellent’ in 78 of 130 (60 per cent) individuals and ‘poor’ or non-existent in 52 of 130 (40 per cent) individuals. Knowledge was positively correlated with hours of exposure, otological complaints and frequency of ear canal protection use. A significant negative influence of neoprene hood use on external auditory exostosis severity was shown.
Conclusion
The positive effect of external auditory exostosis knowledge on the frequency of ear canal protection and the reduction of external auditory exostosis risk implies a need for health education on this topic.
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) may be among the viral agents that affect the audio-vestibular system. This study aimed to investigate vestibular symptoms and videonystagmographic examinations in recovered coronavirus disease 2019 (Covid-19) patients compared with the control group.
Method
The patients were evaluated with Vertigo Symptom Scale questionnaire and audiometric, tympanometric, stapedial reflex and videonystagmographic examinations.
Results
A total of 92 of the patients in the coronavirus disease 2019 patients group and 25 of the volunteers in the control group were included in the study. The mean Vertigo Symptom Scale score was found to be significantly higher (p < 0.001) in the coronavirus disease 2019 group. Furthermore, one of the hospitalised patients was diagnosed with vestibular neuritis.
Conclusion
The vestibular system may also be affected in some coronavirus disease 2019 patients. Although this may be seen as dizziness in some patients, in rare cases it can cause severe issues, such as vestibular neuritis.
To analyse the natural course of infants with otitis media with effusion who failed universal newborn hearing screening and to explore the appropriate observation period.
Methods
This retrospective cohort analysis included infants with otitis media with effusion who failed universal newborn hearing screening every 3 months for 12 months.
Results
The average recovery time of the 155 infants was 7.08 ± 0.32 months after diagnosis. Multivariate Cox regression analysis confirmed that frequent reflux, maxillofacial deformities and initial hearing status were independent factors affecting recovery. Moreover, the cumulative recovery of most infants with mild hearing loss and infants with moderate hearing loss accompanied by frequent reflux was significantly higher at six months after diagnosis than at three months.
Conclusion
For most infants with mild hearing loss, as well as those with moderate hearing loss accompanied by frequent reflux, the observation period can be extended to six months after diagnosis.
Hearing impairment in older adults may affect cognitive function and increase the risk of dementia. Most cognitive tests are delivered auditorily, and individuals with hearing loss may fail to hear verbal instructions. Greater listening difficulty and fatigue in acoustic conditions may impact test performance. This study aimed to examine the effect of decreased audibility on cognitive screening test performance in older adults.
Method
Older adults (n = 63) with different levels of hearing loss completed a standard auditory Mini-Mental State Examination test and a written version of the test.
Results
Individuals with moderate to moderately severe hearing loss (41–70 dB) performed significantly better on the written (24.34 ± 4.90) than on the standard test (22.55 ± 6.25), whereas scores were not impacted for mild hearing loss (less than 40 dB).
Conclusion
Hearing evaluations should be included in cognitive assessment, and test performance should be carefully interpreted in individuals with hearing loss to avoid overestimating cognitive decline.
Cochlear implantation performed under local anaesthesia is an increasingly accepted technique worldwide, though the literature to date includes only single-surgeon and single-centre experiences. This study explored the national experience of UK surgeons using this challenging surgical technique, with the goal of providing consensus recommendations.
Methods
A qualitative analysis was conducted of semi-structured interviews with 10 UK-based cochlear implantation surgeons, focusing on common challenges, how to overcome them and candidate selection.
Results
Cochlear implantation under local anaesthesia can potentially be offered to all eligible adult patients with favourable anatomy. A posterior tympanotomy and round window approach is recommended. Common challenges and recommendations are explored thematically: managing patient, surgeon and staff expectations; optimising communication; patient comfort and position; minimising pain and vertigo; and safe use of sedation.
Conclusion
This is the first study of national experience of cochlear implantation performed under local anaesthesia. Key themes, including refinements to surgical technique and optimising patient comfort and communication, have been explored in depth.
Children with single-sided deafness often receive inconsistent clinical recommendations because there is currently no clear best practice in paediatric single-sided deafness. This systematic review of the literature aimed to compare commonly used treatments and attempted to support the use of a particular treatment modality.
Method
This was a comprehensive literature review from 1 January 2000 to 22 February 2022; the study compared the outcomes of bone conduction devices and cochlear implantation in paediatric patients with single-sided deafness.
Results
Fifteen studies consisting of 202 patients were examined. Variables including speech reception in quiet and noise, as well as quality of life measures were compared. Both cochlear implantation and bone-anchored hearing aids demonstrated benefits in sound perception. Quality of life measures improved with both modalities.
Conclusion
Although both bone-anchored hearing aids and cochlear implantation appear to provide significant improvements, additional research with more direct comparisons is needed to provide more decisive results.
To assess hearing rehabilitation in patients with congenital aural atresia using an active middle-ear implant (Vibrant Soundbridge).
Methods
Of a cohort of 70 microtia and atresia patients, 10 underwent Vibrant Soundbridge implantation between 2008 and 2021. Two of the 10 patients had binaural implantation, resulting in 12 ears for analysis. Pre- and post-operative audiometry data were analysed, and patient satisfaction was evaluated. Surgical issues regarding coupling sites and outcomes were analysed.
Results
Pure tone average (0.5, 1, 2 and 4 kHz) improved from a pre-operative mean (standard deviation) of 65.3 (8.7) dB HL to a post-operative mean of 26.8 (4.9) dB HL. This resulted in a mean pure tone average gain of 38.5 dB HL. The results indicate no obvious difference between stapes (n = 8) and incus (n = 4) coupling. The mean effective gain for 0.5, 1, 2 and 4 kHz was −17.8 dB HL (standard deviation = 4.3). Concerning effective gain, Vibrant Soundbridge performed best at 2 kHz. Patients reported high overall satisfaction, good sound quality and strongly improved directional hearing.
Conclusion
An active middle-ear implant (Vibrant Soundbridge) allows hearing rehabilitation in selected atretic ears, and provides long-term hearing stability in children and adults.
