A novel study on association between untreated hearing loss and cognitive functions of older adults: Baseline non-verbal cognitive assessment results.

BACKGROUND: Age-related hearing loss (ARHL) is highly prevalent in older adults, and more than two-thirds above age of 70 years suffer from ARHL. Recent studies have established a link between ARHL and cognitive impairment; however, most of the studies have used verbally loaded cognitive measures to investigate the association between ARHL and cognition. It is possible that due to hearing impairment, the elderly may experience difficulty in following verbal instructions or completing tasks that heavily rely on hearing during cognitive assessments. This may result in overestimation of cognitive impairment in such individuals. This baseline cross-sectional study investigated the associations between untreated hearing loss and a number of cognitive functions using a battery of non-verbal cognitive tests. Further, association between hearing loss and psychological status of older adults was examined. STUDY DESIGN: Prospective case-controlled study. METHODS: A total of 119 participants (54 males, M=66.33±10.50 years; 65 females M=61.51±11.46 years) were recruited. All participants completed a hearing assessment, a computerised test battery of non-verbal cognitive functions and the depression, anxiety and stress scale. RESULTS: Hierarchical multiple regression analysis results revealed that hearing thresholds significantly associated with the working memory (P<0.05), paired associative learning scores (P<0.05), depression (P<0.001), and anxiety (P<0.001) and stress (P<0.001) scores. Analysis of covariance results revealed that participants with moderately-severe hearing loss performed significantly poorer in paired associative learning and working memory tasks and psychological function tests compared to those with normal hearing. CONCLUSION: Results of the current study suggest a significant relationship between ARHL and both cognition and psychological status. Our results also have some implications for using non-verbal cognitive tests to evaluate cognitive functions in post-lingually hearing impaired ageing adults, at least for those with more than moderately-severe levels of hearing loss.

Does otitis media in early childhood affect later behavioural development? Results from the Western Australian Pregnancy Cohort (Raine) Study.

OBJECTIVES: To examine the relationship between early life episodes of otitis media and later behavioural development with adjustment for confounders. DESIGN: Longitudinal cohort study. SETTING: The Western Australian Pregnancy Cohort (Raine) Study recruited 2900 pregnant women from King Edward Memorial Hospital (KEMH) in Perth, Western Australia, between 1989 and 1991. PARTICIPANTS: Data from the children born were collected at both the Year 3 and Year 5 follow-up. At Year 3, n = 611 were diagnosed with recurrent otitis media through parent-report and clinical examination. At Year 5, n = 299 were considered exposed to otitis media based upon tympanometry results. MAIN OUTCOME MEASURES: Performance in the Child Behaviour Checklist (CBCL), a questionnaire completed by the primary caregiver at Year 10. RESULTS: Significant associations were found between recurrent otitis media at Year 3 and internalising behaviours (P = .011), and the somatic (P = .011), withdrawn (P = .014), attention (P = .003) and thought problems domains (P = .021), and the total CBCL score (P = .010). A significant association was also found between exposure to otitis media at Year 5 and externalising behaviours (P = .026). CONCLUSIONS: A modest association was seen between recurrent otitis media at Year 3 and exposure to otitis media at Year 5 and a number of behaviour domains at Year 10.

Associations between cardiovascular disease and its risk factors with hearing loss-A cross-sectional analysis.

OBJECTIVES: To investigate the relationship between hearing loss and cardiovascular disease risk factors. DESIGN: Cross-sectional study. METHODS: Participants were recruited between May 2010 and December 2015 and answered a health and risk factor questionnaire. Physical and biochemical assessments were performed. SETTING: A community-based population. PARTICIPANTS: A total of 5107 participants born within the years 1946-1964 enrolled in the Busselton Healthy Ageing Study. MAIN OUTCOME MEASURES: Hearing was assessed behaviourally through the best ear pure-tone average (500, 1000, 2000, 4000 Hz), low-frequency average (250, 500, 1000 Hz) and high-frequency average (4000, 8000 Hz). Self-reported hearing loss, tinnitus and hyperacusis were assessed via questionnaire. Cardiovascular risk factors were assessed via a patient-completed questionnaire and objective measurements including blood pressure, body mass index, waist circumference, lipid profile and glycated haemoglobin. RESULTS: Of the participants, 54% were female, with the mean age of 58 years (range 45-69 years). Age, sex and family history of hearing loss were consistently strong determinants of hearing loss outcomes. After adjusting for these, obesity, current smoking, peripheral arterial disease and history of cardiovascular disease were significantly associated with pure-tone, low-frequency and high-frequency hearing loss. In addition, high blood pressure, triglyceride and glycated haemoglobin were significantly associated with low-frequency hearing loss. There was a graded association between hearing loss and Framingham Risk Score for cardiovascular risk (P<0.001). CONCLUSIONS: Established cardiovascular disease and individual and combined cardiovascular disease risk factors were found to be associated with hearing loss. Future research should prospectively investigate whether targeting cardiovascular disease can prevent hearing loss.

A population-based study of the association between dysglycaemia and hearing loss in middle age.

AIMS: To investigate the independent associations between hearing loss and dysglycaemia in a sample of middle-aged adults, including separate analysis of those aged < 60 years. METHODS: The first 2023 participants in the cross-sectional Busselton Health Ageing Survey were assessed for hearing loss ≥ 26 dB (better ear) for four-frequency average (4FA) of pure-tone thresholds at 500, 1000, 2000 and 4000 Hz, and high-frequency average (HFA) of pure-tone thresholds at 4000 and 8000 Hz. RESULTS: Valid data from 1864 participants in the Busselton Health Ageing Survey [92.1%; mean ± sd age 56.2 ± 5.5 years, 46.0% men, 120 (7.0%) with diabetes, 274 (14.7%) with prediabetes] were analysed, of whom 103 (5.5%) had four-frequency average hearing loss and 561 (30.1%) had high-frequency average hearing loss. In multivariable analyses, glycaemic status was not independently associated with four-frequency or high-frequency average hearing loss. In the 1286 participants aged < 60 years, there was no relationship between dysglycaemia and high-frequency average hearing loss, but the prevalence of four-frequency average hearing loss increased from 2.3% (95% CI 1.5-3.4) in participants with normoglycaemia to 5.7% (95% CI 3.0-10.6) in those with prediabetes and 10.2% (4.2-21.5) in those with diabetes (trend P = 0.003). In multivariable analysis with normoglycaemia as reference, the odds ratios for four-frequency average hearing loss were 2.84 (95% CI 1.29-6.27) for prediabetes and 5.93 (95% CI 1.67-21.05) for diabetes (P ≤ 0.01) in the < 60 year age group. CONCLUSIONS: There was progressively increasing mid-range hearing loss with worsening glucose tolerance in younger individuals, suggesting dysglycaemia-associated early-onset presbycusis.

Self-reported cochlear implant management skills: development and validation of the self-administered Cochlear Implant Management Skills (CIMS-self) survey.

OBJECTIVE: A self-administered device management survey was developed and validated to investigate the ability of cochlear implant recipients to self-report physical handling and care for their hearing implant device(s) and to identify factors that may influence self-reported management skills. DESIGN: Survey development and validation. A prospective convenience cohort design study. SETTING: Specialist hearing implant clinic. PARTICIPANTS: Forty-nine post-lingually hearing impaired, adult cochlear implant recipients, at least 12 months postoperative. MAIN OUTCOME MEASURES: Survey test-retest reliability, responsiveness, criterion validity and sensitivity and specificity compared to clinician evaluation of device management skills. Correlations between self-reported management skills and participant demographic, audiometric, cognitive function, clinical outcomes and device factors. RESULTS: The self-administered Cochlear Implant Management Skills survey was developed, demonstrating high test-retest reliability (ICC = 0.884, P < 0.001; CI 95%: 0.721-0.952), responsiveness to intervention (management skills training) [t(20) = -3.245, P = 0.004], criterion validity (ICC = 0.765, P < 0.001; CI 95%: 0.584-0.868) and sensitivity (0.89). No associations were found between self-reported management skills and participant factors. CONCLUSIONS: This study demonstrated that a self-report survey is an effective method for the evaluation of skills required for cochlear implant device management.

Protective benefit of predominant breastfeeding against otitis media may be limited to early childhood: results from a prospective birth cohort study.

OBJECTIVES: To examine the long-term effects of predominant breastfeeding on incidence of otitis media. DESIGN: Prospective birth cohort study. SETTING: The West Australian Pregnancy Cohort (Raine) Study recruited 2900 mothers through antenatal clinics at the major tertiary obstetric hospital in Perth, Western Australia, between 1989 and 1992. PARTICIPANTS: In total, 2237 children participated in a 6-year cohort follow-up, and a subset of 1344 were given ear and hearing assessments. MAIN OUTCOME MEASURES: OM diagnosis at 6 years of age (diagnosed by low-compliance tympanograms, 0-0.1 mmho). This was compared to OM diagnosed at the 3-year cohort follow-up using parent-report measures. Main exposure measures were duration of predominant breastfeeding (defined as the age other milk was introduced) and duration of partial (any) breastfeeding (defined as the age breastfeeding was stopped). RESULTS: There was a significant, independent association between predominant breastfeeding (OR = 1.33 [1.04, 1.69]; P = 0.02) and OM, and breastfeeding duration (OR = 1.35 [1.08, 1.68]; P = 0.01) with OM at 3 years of age. However, at 6 years of age, this relationship was no longer statistically significant (predominant breastfeeding OR = 0.78 [0.48, 1.06]; P = 0.09; duration of breastfeeding, OR = 1.34 [0.81, 2.23]; P = 0.25). CONCLUSIONS: Our findings are in line with a number of epidemiological studies which show a positive association between breastfeeding and OM in early childhood. However, the long-term follow-up of these children revealed that by 6 years of age, there was no significant influence of breastfeeding on presence of OM. These results suggest that the protective effect of predominant breastfeeding for at least 6 months does not extend to school-age children, where other social and environmental factors may be stronger predictors of OM.

A prospective study evaluating cochlear implant management skills: development and validation of the Cochlear Implant Management Skills survey.

OBJECTIVE: To investigate the ability of cochlear implant (CI) recipients to physically handle and care for their hearing implant device(s) and to identify factors that may influence skills. To assess device management skills, a clinical survey was developed and validated on a clinical cohort of CI recipients. DESIGN: Survey development and validation. A prospective convenience cohort design study. SETTING: Specialist hearing implant clinic. PARTICIPANTS: Forty-nine post-lingually deafened, adult CI recipients, at least 12 months postoperative. MAIN OUTCOME MEASURES: Survey test-retest reliability, interobserver reliability and responsiveness. Correlations between management skills and participant demographic, audiometric, clinical outcomes and device factors. RESULTS: The Cochlear Implant Management Skills survey was developed, demonstrating high test-retest reliability (0.878), interobserver reliability (0.972) and responsiveness to intervention (skills training) [t(20) = -3.913, P = 0.001]. Cochlear Implant Management Skills survey scores range from 54.69% to 100% (mean: 83.45%, sd: 12.47). No associations were found between handling skills and participant factors. CONCLUSIONS: This is the first study to demonstrate a range in cochlear implant device handling skills in CI recipients and offers clinicians and researchers a tool to systematically and objectively identify shortcomings in CI recipients' device handling skills.

The relationship between hearing impairment and cognitive function: a meta-analysis in adults.

OBJECTIVE: Hearing loss affects over 1.23 billion people globally. It has been proposed that hearing impairment negatively impacts on cognition. Some studies have demonstrated a faster rate of decline in cognition, and increased risk of incident all-cause dementia. This finding is not ubiquitous. This study used meta-analysis to examine the evidence-base regarding the relationship between hearing and cognition. DESIGN: A systematic review of the literature and meta-analyses of study findings were conducted. Published and grey literature was reviewed. Papers were included if they studied the relationship between hearing and cognition in adults with and without hearing impairment. MAIN OUTCOME MEASURES: Meta-analyses examined evidence for and against seven questions. Is cognition poorer in individuals with normal hearing compared to (i) untreated or (ii) treated hearing impairment, is cognition associated with degree of hearing impairment in (iii) untreated and/or (iv) treated hearing, is cognition (v) different in untreated compared to treated hearing impairment, (vii) does cognition improve after intervention, and (vii) how is hearing impairment differentially associated with cognitive ability across six domains of cognition? RESULTS: The 33 included studies contributed 40 samples, with a total of 602 participants with untreated hearing impairment, 672 participants with treated hearing impairment, 176 healthy controls, and 4260 individuals with a range of hearing impairment with/without treatment. The results demonstrated that cognition is significantly poorer in (i) individuals with untreated hearing and remains poorer in (ii) treated hearing impairment compared to normal hearers. The degree of cognitive deficit is significantly associated with the degree of hearing impairment in both (iii) untreated and (iv) treated hearing impairment. Furthermore, (v) hearing intervention significantly improves cognition. Finally, (vii) hearing impairment impacted on all domains of cognition. CONCLUSIONS: This meta-analysis suggests that hearing impairment is associated with cognitive problems. However, due to diversity within studies, small sample sizes, the failure to control for premorbid and other health factors, this conclusion may be premature.

Utilization of fresh human tympanic membranes for structural analysis and cytokeratin immunocytochemistry implementing resin techniques.

CONCLUSIONS: The results of this study have demonstrated for the first time that tympanic membrane (TM) structure is preserved following removal of fresh, normal tissue from patients undergoing surgery. Greater clarity has been demonstrated using resin sections than in previous studies on paraffin sections. Of particular note, cytokeratin (CK) immunocytochemistry was successfully performed on resin sections, which has not been previously reported. This may have potential applications for future work involving tissues that express CKs. OBJECTIVES: To analyse the structure of normal, fresh human TM specimens after surgical removal and to evaluate their CK immunocytochemistry using resin techniques, neither of which have been demonstrated previously. MATERIAL AND METHODS: Seven TM specimens were removed during surgery and then preserved in a modified Karnovsky's fixative. Semi-thin and thin sections were examined by means of light and electron microscopy, respectively. For comparison purposes, paraffin block-embedded specimens were also sectioned. CK immunocytochemistry was performed on semi-thin sections using standard immunoperoxidase techniques, with expression being demonstrated using light microscopy. RESULTS: The three-layer architecture of the TM was preserved. The morphology of the TM was vastly superior in the semi-thin resin sections than in the thicker paraffin sections. The outer, middle and inner layers were clearly demonstrated. The integrity of the outer epithelial layer was maintained, with an outer keratinizing stratum corneum and underlying stratum granulosum, stratum spinosum and stratum basale layers resting on the basal lamina. The thin inner mucosal layer was also viable, consisting of simple squamous or cuboidal cells. Preservation of the middle lamina propria was achieved, with demonstration of the outer radial and inner circular fibres. CK immunocytochemistry utilizing resin techniques provided excellent staining of CK 7 and 8 in the inner layer, with positive staining of CK 5 and 10 in the outer layer.

A study of variance in densitometry of retinal nerve fiber layer photographs in normals and glaucoma suspects.

The main object of this research was to develop a reliable method of screening glaucoma suspects and patients for early loss of or changes in the retinal nerve fiber layer (RNFL). This study quantifies the variances due to photography, digitizing, and analysis of red-free photographs of the RNFL. The influence of pupil size, optic disc position and eye movements, film processing, digitizing, and intra- and interphotographic-session and intra- and interoperator variances were established. It was found that pupils needed to be dilated to at least 6 mm, that the optic disc had to be positioned in a standardized area in the negative, that the head of the subject had to remain still during photography, and that film processing and digitizing of the negative needed to be strictly controlled to minimize the variance in collection of densitometry data from RNFL red-free photographs. It was established that focusing of the negatives during digitization was not crucial. Criteria were defined for acceptable negatives. Interphotographic-session and intraoperator variances were not significant in most cases when negatives were digitized to these criteria. Analysis of interphotographic-session variance showed that there were still some factors in photography, film processing, and/or image digitizing that were not sufficiently controlled for long-term follow-up without normalization of the data. Densitometry data gathered using the established protocol, from negatives of 71 subjects were analyzed; best sensitivity and specificity rates of 80% and 100%, respectively, were achieved for the diagnosis of glaucoma.

Methods and limits of digital image compression of retinal images for telemedicine.

PURPOSE: To investigate image compression of digital retinal images and the effect of various levels of compression on the quality of the images. METHODS: JPEG (Joint Photographic Experts Group) and Wavelet image compression techniques were applied in five different levels to 11 eyes with subtle retinal abnormalities and to 4 normal eyes. Image quality was assessed by four different methods: calculation of the root mean square (RMS) error between the original and compressed image, determining the level of arteriole branching, identification of retinal abnormalities by experienced observers, and a subjective assessment of overall image quality. To verify the techniques used and findings, a second set of retinal images was assessed by calculation of RMS error and overall image quality. RESULTS: Plots and tabulations of the data as a function of the final image size showed that when the original image size of 1.5 MB was reduced to 29 KB using JPEG compression, there was no serious degradation in quality. The smallest Wavelet compressed images in this study (15 KB) were generally still of acceptable quality. CONCLUSIONS: For situations where digital image transmission time and costs should be minimized, Wavelet image compression to 15 KB is recommended, although there is a slight cost of computational time. Where computational time should be minimized, and to remain compatible with other imaging systems, the use of JPEG compression to 29 KB is an excellent alternative.

Absorption of 193- and 213-nm laser wavelengths in sodium chloride solution and balanced salt solution.

OBJECTIVE: To determine absorption coefficients for sodium chloride solution (saline) and balanced salt solution at the 193- and 213-nm laser wavelengths. METHODS: Absorption coefficients were obtained for each of the component species found in balanced salt solution. This was achieved by measuring laser pulse transmission through solutions of varying concentration. The experiments were repeated using the 193-nm excimer and 213-nm solid-state laser wavelengths. Results for each species were then used to obtain an overall absorption coefficient and penetration depth for balanced salt solution and 0.9% sodium chloride solution. RESULTS: Absorption coefficients in balanced salt solution for the 193- and 213-nm wavelengths were found to be 140 and 6.9 cm(-1), respectively. In 0.9% sodium chloride solution, the absorption coefficient was 81 cm(-1) at 193 nm and 0.05 cm(-1) at 213 nm. At 193 nm, absorption in balanced salt solution was dominated by sodium chloride. Sodium citrate emerged as the dominant species of absorption at 213 nm. CONCLUSIONS: For the species investigated, we found reduced absorption for the longer wavelength of 213 nm. While the difference in wavelength between 193 and 213 nm is within about 10%, the respective molar absorption coefficients varied by 1 to 4 orders of magnitude. This indicates that predictions for the wavelength-dependent changes of absorption coefficients of other solutions are unreliable. CLINICAL RELEVANCE: Fluid placed on the surface of the cornea during keratorefractive surgery has proved to be a barrier to ablation for the 193-nm wavelength. The increased penetration depth through sodium chloride solution and balanced salt solution for the longer 213-nm laser wavelength may mean that these solutions cannot be used as a masking agent for keratorefractive procedures performed with this wavelength.

Determining the accuracy of an eye tracking system for laser refractive surgery.

PURPOSE: Patient eye and head movements during laser refractive surgery may result in errors between the surgical beam position and the desired location for optimum correction. This, in turn, may lead to reduced postoperative vision, including increased higher order aberrations of the eye. Active eye tracking systems are often incorporated into laser delivery systems, which aim to reduce the effect of patient eye movement. METHODS: In this study, the accuracy of an eye tracking system designed for laser refractive surgery was determined. An enucleated porcine eye was attached to a scanning device and the movement measured using the eye tracking system. The recorded position is compared to the preprogrammed position of the scanning device. RESULTS: The system demonstrated an accuracy of 0.06 m for an intact cornea and 0.1 mm for a cornea with a thin flap removed. This compares to an average decentration of ablation of 0.4 mm for patients relying on passive fixation, as measured by previous clinical trials. CONCLUSION: implementation of this eye tracker would lead to improved alignment between the laser and eye during laser refractive surgery.

Registration of stereo and temporal images of the retina.

The registration of retinal images is required to facilitate the study of the optic nerve head and the retina. The method we propose combines the use of mutual information as the similarity measure and simulated annealing as the search technique. It is robust toward large transformations between the images and significant changes in light intensity. By using a pyramid sampling approach combined with simulated reannealing we find that registration can be achieved to predetermined precision, subject to choice of interpolation and the constraint of time. The algorithm was tested on 49 pairs of stereo images and 48 pairs of temporal images with success.

Evaluation of a portable fundus camera for use in the teleophthalmologic diagnosis of glaucoma.

PURPOSE: The digital images of the optic disk from a portable fundus camera were evaluated for suitability in teleophthalmologic screening for glaucoma. METHODS: Fifty-one eyes of 27 consecutive patients from our glaucoma clinic were dilated and photographed with a Zeiss FF retinal camera (Carl Zeiss, Oberkochen, Germany) and a portable Nidek NM-100 (Nidek, Tokyo, Japan) fundus camera. Digital images from the portable fundus camera were digitized, compressed and stored in a Fujix DF-10M (Fuji, Tokyo, Japan) digitizer. Lossy compressed digital images and photographs from the Zeiss camera were presented separately in random order to three ophthalmologists for estimation of vertical cup:disk ratios (VCDR) and to evaluate image quality as good, acceptable, or unacceptable for screening glaucoma. Gold standard VCDRs were measured from monoscopic photographic slides obtained using the Zeiss camera by a fourth ophthalmologist. RESULTS: Measurement of agreement (Kappa values) between estimated VCDR of digital images and photographs by the three ophthalmologists were 0.52, 0.38, and 0.50 respectively. Agreement between gold standard and estimated VCDR from photographs were 0.87, 0.45, and 0.84 respectively (specificity between 79% and 97%, sensitivity between 70% and 95%). Kappa values obtained between gold standard and estimated VCDR from digital images were 0.52, 0.49, and 0.49, respectively (specificity between 68% and 79%, sensitivity between 67% and 87%. CONCLUSION: Moderate to good agreement indicates that the digital images from the portable fundus camera may be suitable for optic disk assessment in the current configuration. This easy to use Nidek hand-held camera could be a viable instrument for teleophthalmology if a better digitizing system is incorporated to improve the quality of the images.

Computerised densitometry of red-free retinal photographs correlated with automatic perimetry.

An image analyser installed in a 16 bit personal computer was used to measure grey levels in red free photographs of normal and glaucomatous eyes. Regional photographic image intensity and density were correlated with Humphrey Field Analyser results for corresponding areas of visual field. Two methods for standardising photographic exposure by histogram equalisation and slide were compared in two groups of eyes from 13 subjects. For histogram equalisation, r2 varied from 0.16 to 0.29 for linear fits in temporal retinal quadrants. For the histogram slide, r2 varied between 0.19 to 0.45 for linear fits. Similar results were found for mean histogram equalised image intensity versus Humphrey Field Analyser global indices: Mean Deviation, (r2 = 0.27) and Pattern Standard Deviation, (r2 = 0.37). For histogram equalised image data, resistant line analysis showed a linear goodness of fit of 0.92 and for histogram slide goodness of fit was 0.97 for upper and 0.87 for lower temporal quadrants.

Microprocessor-based television games, exercises, and evaluation procedures for the physically and mentally handicapped.

We describe here techniques designed to aid both the physically and mentally handicapped. T.V. games and exercises for the handicapped have been designed and tested with patients. The system initially consisted of a central game box with a microprocessor, interchangeable memory cards, and body joint angle transducers which operate with a standard color television set. Associated software and additional transducers have been developed. The transducers used to date include lightpens, potentiometers, joysticks, the computer mouse and pressure sensors. All games and exercises developed have varying degrees of therapeutic, diagnostic, entertainment and educational value, although the emphasis has been on the therapeutic and diagnostic applications.

Utilising silk fibroin membranes as scaffolds for the growth of tympanic membrane keratinocytes, and application to myringoplasty surgery.

BACKGROUND: Chronic tympanic membrane perforations can cause significant morbidity. The term myringoplasty describes the operation used to close such perforations. A variety of graft materials are available for use in myringoplasty, but all have limitations and few studies report post-operative hearing outcomes. Recently, the biomedical applications of silk fibroin protein have been studied. This material's biocompatibility, biodegradability and ability to act as a scaffold to support cell growth prompted an investigation of its interaction with human tympanic membrane keratinocytes. METHODS AND MATERIALS: Silk fibroin membranes were prepared and human tympanic membrane keratinocytes cultured. Keratinocytes were seeded onto the membranes and immunostained for a number of relevant protein markers relating to cell proliferation, adhesion and specific epithelial differentiation. RESULTS: The silk fibroin scaffolds successfully supported the growth and adhesion of keratinocytes, whilst also maintaining their cell lineage. CONCLUSION: The properties of silk fibroin make it an attractive option for further research, as a potential alternative graft in myringoplasty.

Patient's quality of life and hearing outcomes after stapes surgery.

OBJECTIVES: To determine the quality of life (QOL) after stapes surgery and whether audiological parameters for hearing correlate with specific QOL factors. DESIGN: A retrospective cross-sectional study. SETTING: A tertiary referral centre. PARTICIPANTS: A series of 35 patients who underwent stapes surgery of which three were excluded because they were <18 years of age, chronically or mentally ill, or in a dependant relationship. Response rate was 93% (30/32). Nine were further excluded because they had revision or bilateral surgery, or missing data. Twenty-one patients were included in this study. MAIN OUTCOME MEASURES: The Glasgow Benefit Inventory (GBI) was used to evaluate general QOL and the Hearing Disability and Handicap Scale (HDHS) was used as a disease-specific measure. The Belfast Rule of Thumb and Glasgow Benefit Plot assessed hearing outcomes. RESULTS: Operative success was 86% using the Belfast Rule of Thumb and 95% had closure of the air-bone gap to within 20 dB. 81.8% of patients reported a better overall QOL as surgery. Glasgow Benefit Inventory Social and GBI Physical scores correlated positively with the HDHS speech component (P < 0.05). The duration of hearing loss correlated inversely with the average HDHS score (P < 0.05). CONCLUSION: The majority of patients report a better QOL as undergoing stapes surgery. Speech impacts on people's physical and social QOL of patients. Quality of life tools, in addition to objective audiologic measurements can provide clinicians with patients' subjective perspective that helps guide clinical decision-making and counselling.
