RESUMEN
BACKGROUND: Surgical coaching programs have been introduced as platforms for ongoing professional development amongst independently practicing surgeons. While there is a plethora of evidence regarding the effectiveness of surgical coaching for practicing staff surgeons, patients' opinions regarding surgical coaching are largely unknown. OBJECTIVES: To determine patients' baseline attitudes and opinions about the hypothetical situation of their treating surgeon having a surgical coach present during their upcoming operation, and to determine patients' baseline knowledge and prior exposure to surgical coaching. DESIGN AND SETTING: This study was conducted at a tertiary hospital in Vancouver, Canada. Patients on the surgical waitlist of 2 independently practicing Otolaryngologists within the subspeciality of Neurotology were invited to participate in the study. Participants engaged in a semi-structured interview to discuss their opinions and knowledge of physician coaches and to learn about surgical coaching. The interview was conducted based on a pre-set script. RESULTS: Of the 100 patients approached, 70 consented to participate. Forty-three (61%) participants identified as female, and the mean age was 56±15 years. Initially, 84% of participants (nâ¯=â¯59) consented to the hypothetical presence of a surgical coach. Post-discussion, this number increased to 95.7% (nâ¯=â¯67, pâ¯=â¯0.04). Prior participant exposure to coaching related to employment, education, athletics, or music was high (90%, nâ¯=â¯63). Younger participants between 25 and 45 years of age were more amenable to the presence of a surgical coach compared to participants >66 years of age (pâ¯=â¯0.01). After the interview, 55 (79%) participants were interested in learning more about surgical coaching. CONCLUSION: Many patients were unaware of the rationale and importance of surgical coaching programs for practicing staff surgeons. Most patients, especially younger patients, were amenable to the presence of a surgical coach during their surgery, and this number increased in all age categories with patient education about surgical coaching.

OBJECTIVE: Menière's disease (MD) is a clinical disorder that often provides challenges in diagnosis and management. High-quality evidence to guide care providers is sparse, which can result in significant practice variations. Quality indicators (QIs) are one method that can be used to standardize and measure accepted care practices to improve healthcare quality and patient outcomes. Here, we developed practical, high-yield QIs that serve to measure and inform the quality of care provided to patients with MD. STUDY DESIGN: Modified RAND Corporation University of California, Los Angeles appropriateness methodology for QI development. SETTING: Multicenter nine-member expert panel. PATIENTS: NA. INTERVENTIONS: NA. MAIN OUTCOME MEASURE: Final QIs deemed appropriate measures of quality care with agreement by the expert panel. RESULTS: Twenty-seven candidate indicators were identified after literature review. After the first round of evaluations, the panel agreed on three candidate indicators as appropriate QIs. A subsequent expert panel meeting provided a platform to discuss disagreements. Two agreed-upon QIs were revised during this discussion before final evaluations. The expert panel ultimately agreed upon five QIs as appropriate measures of high-quality care after completing final evaluations and reviewing updated literature. The five quality indicators measure audiometric documentation, minimization of electrocochleography, use of intratympanic dexamethasone, use of intratympanic gentamycin, and rate of labyrinthectomy/vestibular neurectomy in refractory MD patient. CONCLUSIONS: This study proposes five QIs that cover key aspects of care for MD, such as accurate diagnosis and management options including initial destructive therapies. These QIs can serve multiple purposes, the most important of which is to galvanize quality improvement initiatives.

OBJECTIVE: Sudden sensorineural hearing loss (SSNHL) is an ideal entity for quality indicator (QI) development, providing treatment challenges resulting in variable or substandard care. The American Academy of Otolaryngology-Head and Neck Surgery recently updated their SSNHL guidelines. With SSNHL demonstrating a large burden of illness, this study sought to leverage the updated guidelines and develop QIs that support quality improvement initiatives at an individual, institutional, and systems level. METHODS: Candidate indicators (CIs) were extracted from high-quality SSNHL guidelines that were evaluated using the Appraisal of Guidelines for Research and Evaluation II tool. Each CI and its supporting evidence were summarized and reviewed by a nine-member expert panel based on validity, reliability, and feasibility of measurement. Final QIs were selected from CIs using the modified RAND Corporation-University of California, Los Angeles appropriateness methodology. RESULTS: Fifteen CIs were identified after literature review. After the first round of evaluations, the panel agreed on 11 candidate indicators as appropriate QIs with 2 additional CIs suggested for consideration. An expert panel meeting provided a platform to discuss areas of disagreement before final evaluations. The expert panel subsequently agreed upon 11 final QIs as appropriate measures of high-quality care for SSNHL. CONCLUSION: The 11 proposed QIs from this study are supported by evidence and expert consensus, facilitating measurement across a wide breadth of quality domains. With the recently updated SSNHL guidelines, and a greater focus on quality improvement opportunities, these QIs may be used by healthcare providers for targeted quality improvement initiatives.

OBJECTIVES/HYPOTHESIS: The pathophysiology of idiopathic sudden sensorineural hearing loss (ISSNHL) is still unknown, but labyrinthine artery infarction has been proposed. The objective of this study was to perform a systematic review and conduct a meta-analysis assessing the risk of developing stroke and myocardial infarction after presentation with ISSNHL. METHODS: A systematic literature review was conducted using Pubmed, Embase, Web of Science, and Cochrane Libraries. All studies investigating an association between ISSNHL and stroke and/or myocardial infarction (MI) were included. Adhering to the MOOSE guideline, two independent reviewers extracted data, assessed risk of bias, and evaluated the relevance and quality of evidence. RESULTS: Three observational studies evaluating the risk of stroke in ISSNHL were included (n = 6,521 patients). All individual study results indicated an increased relative risk of stroke after ISSNHL (unadjusted relative risk range 1.21-1.63). Pooled adjusted hazard ratios revealed a 1.42-fold increased risk of stroke after ISSNHL (hazard ratio [HR] 1.42; 95% confidence interval [CI] 1.15-1.75, I2 = 55%). Subgroup analysis of one study demonstrated that the increased risk is only present in adults aged above 50 years (HR 1.23; 95% CI 1.07-1.42). Five observational studies evaluating the risk of MI in patients with ISSNHL were included (n = 61,499 patients). Pooled analyses demonstrated that ISSNHL was not associated with MI (HR 1.08, 95% CI 0.87-1.34). CONCLUSION: ISSNHL may be an independent risk factor for the subsequent development of stroke especially in a subgroup of elderly patients. More studies are needed to confirm this association and to assess whether such patients would benefit from cardiovascular risk assessment and management to prevent future strokes.

OBJECTIVE: Vestibular deficit patients have an increased fall risk and fear of falling. Postural threat, known to increase balance-related fear and anxiety, influences vestibular gains during quiet standing in young healthy adults. The current study examined whether there is a similar relationship for peripheral unilateral vestibular loss (UVL) patients in comparison to age-matched healthy controls (HC). SETTING: University laboratory. STUDY DESIGN: Prospective laboratory study. PATIENTS AND CONTROLS: Eleven UVL patients, nine with vestibular neurectomy. Eleven aged-matched HCs. MAIN OUTCOME MEASURES: Subjects stood on a hydraulic lift placed at two heights: low (0.8âm, away from the edge) and high (3.2âm, at the edge). Amplitude (root mean square), mean power frequency (MPF), and mean position were analyzed for center of foot pressure (COP) and 90% ranges for angle amplitude and velocity for trunk sway. RESULTS: Group interactions were strongest for anterior-posterior (AP) COP and trunk pitch angle. AP lean away from the edge was greater in HCs than UVLs. HCs, but not UVLs had a decrease in root mean square AP COP with height. Trunk pitch sway was changed similarly. Both groups had increased trunk pitch velocity at height. Changes with height were less for roll: MPF of lateral COP increased with height for UVLs with no changes for HCs, and trunk roll amplitude decreased for both groups. CONCLUSIONS: This report provides evidence for a differential effect of height induced postural threat on balance control between UVLs and HCs presumably due to the reduced vestibular-spinal gain in UVL subjects.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for Coronavirus disease 2019 (COVID-19) has a predilection for infecting the mucosa of the upper and lower airways. Otolaryngologists and supporting health care workers (HCWs) are particularly at high risk of becoming infected while treating patients as many in-office procedures and surgeries are Aerosol Generating Medical Procedures (AGMP). Based on a review of the literature and various guidelines, recommendations are made to mitigate the risk to health care workers of becoming infected with SARS-CoV-2 while providing clinical care. RECOMMENDATIONS: During the COVID-19 pandemic all elective and non-time sensitive Otolaryngology procedures should be deferred to mitigate the risk of transmission of infection to HCWs. For non-AGMPs in all patients, even COVID-19 positive patients Level 1 PPE (surgical mask, gown, gloves and face shield or goggles) is sufficient. If local prevalence is favourable and patients are asymptomatic and test negative for SARS-CoV-2, Level 1 PPE can be used during short duration AGMPs, with limited risk of infected aerosol spread. For AGMPs in patients who test positive for SARS-CoV-2 a minimum of Level 2 PPE, with adequate protection of mucosal surfaces, is recommended (N95/FFP2 respirator, gown, double gloves, goggles or face shield and head cover). For long duration AGMPs that are deemed high-risk in COVID-19 positive patients, Level 3 PPE can provide a higher level of protection and be more comfortable during long duration surgeries if surgical hoods or PAPRs are used. It is recommended that these procedures are performed in negative pressure rooms, if available. It is essential to follow strict donning and doffing protocols to minimize the risk of contamination. CONCLUSIONS: By following strict infection prevention recommendations, the risk of HCWs becoming infected with SARS-CoV-2 while treating patients can be minimized. As the COVID-19 pandemic evolves rapidly, these recommendations should serve as guidance and need to be interpreted based on local factors and availability of healthcare resources.

BACKGROUND: Aerosol generating medical procedures (AGMPs) present risks to health care workers (HCW) due to airborne transmission of pathogens. During the COVID-19 pandemic, it is essential for HCWs to recognize which procedures are potentially aerosolizing so that appropriate infection prevention precautions can be taken. The aim of this literature review was to identify potential AGMPs in Otolaryngology - Head and Neck Surgery and provide evidence-based recommendations. METHODS: A literature search was performed on Medline, Embase and Cochrane Review databases up to April 3, 2020. All titles and abstracts of retrieved studies were evaluated and all studies mentioning potential AGMPs were included for formal review. Full text of included studies were assessed by two reviewers and the quality of the studies was evaluated. Ten categories of potential AGMPs were developed and recommendations were provided for each category. RESULTS: Direct evidence indicates that CO2 laser ablation, the use of high-speed rotating devices, electrocautery and endotracheal suctioning are AGMPs. Indirect evidence indicates that tracheostomy should be considered as potential AGMPs. Nasal endoscopy and nasal packing/epistaxis management can result in droplet transmission, but it is unknown if these procedures also carry the risk of airborne transmission. CONCLUSIONS: During the COVID-19 pandemic, special care should be taken when CO2 lasers, electrocautery and high-speed rotating devices are used in potentially infected tissue. Tracheal procedures like tracheostomy and endotracheal suctioning can also result in airborne transmission via small virus containing aerosols.

OBJECTIVE: School hearing screening is a public health intervention that can improve care for children who experience hearing loss that is not detected on or develops after newborn screening. However, implementation of school hearing screening is sporadic and supported by mixed evidence to its economic benefit. This scoping review provides a summary of all published cost-effectiveness studies regarding school hearing screening programs globally. At the time of this review, there were no previously published reviews of a similar nature. DATA SOURCES: A structured search was applied to 4 databases: PubMed (Medline), Embase, CINAHL, and Cochrane Library. REVIEW METHODS: The database search was carried out by 2 independent researchers, and results were reported in accordance with the PRISMA-ScR checklist and the JBI methodology for scoping reviews. Studies that included a cost analysis of screening programs for school-aged children in the school environment were eligible for inclusion. Studies that involved evaluations of only neonatal or preschool programs were excluded. RESULTS: Four of the 5 studies that conducted a cost-effectiveness analysis reported that school hearing screening was cost-effective through the calculation of incremental cost-effectiveness ratios (ICERs) via either quality- or disability-adjusted life years. One study reported that a new school hearing screening program dominated the existing program; 2 studies reported ICERs ranging from 1079 to 4304 international dollars; and 1 study reported an ICER of £2445. One study reported that school-entry hearing screening was not cost-effective versus no screening. CONCLUSION: The majority of studies concluded that school hearing screening was cost-effective. However, significant differences in methodology and region-specific estimates of model inputs limit the generalizability of these findings.

OBJECTIVE: To evaluate the efficacy of cognitive and/or behavioral therapies in improving health-related quality of life (HRQOL), depression, and anxiety associated with tinnitus. DATA SOURCES: EMBASE, MEDLINE, PubMed, PsycINFO, and the Cochrane Registry were used to identify English studies from database inception until February 2018. STUDY SELECTION: Randomized controlled trials (RCTs) comparing cognitive and/or behavioral therapies to one another or to waitlist controls for the treatment of tinnitus were included. DATA EXTRACTION: Quality and risk were assessed using GRADE and Cochrane's Risk of Bias tool respectively. DATA SYNTHESIS: Pairwise meta-analysis (12 RCTs: 1,144 patients) compared psychological interventions to waitlist controls. Outcomes were measured using standardized mean differences (SMDs) and 95% confidence intervals (CI). I and subgroup analyses were used to assess heterogeneity. Network meta-analysis (NMA) (19 RCTS: 1,543 patients) compared psychological therapies head-to-head. Treatment effects were presented by network diagrams, interval plots, and ranking diagrams indicating SMDs with 95% CI. Direct and indirect results were further assessed by inconsistency plots. CONCLUSIONS: Results are consistent with previously published guidelines indicating that CBT is an effective therapy for tinnitus. While guided self-administered forms of CBT had larger effect sizes (SMD: 3.44; 95% CI: -0.022, 7.09; I: 99%) on tinnitus HRQOL, only face-to-face CBT was shown to make statistically significant improvements (SMD: 0.75; 95% CI: 0.53, 0.97; I: 0%). Guided self-administered CBT had the highest likelihood of being ranked first in improving tinnitus HRQOL (75%), depression (83%), and anxiety (87%), though statistically insignificant. This NMA is the first of its kind in this therapeutic area and provides new insights on the effects of different forms of cognitive and/or behavioral therapies for tinnitus.

The Choosing Wisely Canada Campaign aims to raise awareness amongst physicians and patients regarding unnecessary tests and treatment. The otology/neurotology subspecialty group within the Canadian Society of Otolaryngology - Head & Neck Society developed a list of five common otologic presentations to help physicians deliver high quality effective care: (1) Don't order specialized audiometric and vestibular testing to screen for peripheral vestibular disease, (2) Don't perform computed tomography or blood work in the evaluation of sudden sensorineural hearing loss, (3) Don't perform auditory brain responses (ABR) in patients with asymmetrical hearing loss, (4) Don't prescribe oral antibiotics as first line treatment for patients with painless otorrhea associated with tympanic membrane perforation or tympanostomy tube, and (5) Don't perform particle repositioning maneuvers without a clinical diagnosis of posterior canal benign paroxysmal positional vertigo.

BACKGROUND: The underlying pathophysiology of idiopathic sudden sensorineural hearing loss (ISSNHL) is still unknown. However, an increasing number of observational studies report intralabyrinthine signal alterations in patients with ISSNHL using three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) magnetic resonance imaging (MRI). These findings warrant a meta-analysis. OBJECTIVE OF REVIEW: To conduct a meta-analysis assessing the value of 3D-FLAIR MRI in identifying possible underlying labyrinthine pathophysiologic mechanisms and prognostication in patients with ISSNHL. SEARCH STRATEGY: Two reviewers independently searched the Pubmed, Embase and Cochrane Library from inception until October 10, 2018 and evaluated eligibility based on titles and abstracts of all retrieved studies. All studies reporting on 3D-FLAIR imaging in ISSNHL were included. Subsequently, the full text of eligible studies were evaluated. EVALUATION METHOD: Adhering to the MOOSE guideline, two independent reviewers extracted data, assessed risk of bias and evaluated the relevance and quality of evidence. Data on the number of patients and events were extracted and hearing levels were converted to standardised mean differences (SMD) for conducting meta-analyses. Random effects models for meta-analyses were applied. RESULTS: Eight observational studies met our inclusion criteria (n = 638 patients). In 29%, high signal intensity was found on 3D-FLAIR imaging, suggesting labyrinthine pathology (labyrinthitis [79%], intralabyrinthine haemorrhage [21%]). High signal intensity on 3D-FLAIR was associated with poorer hearing (SMD: 14 dB, 95% CI 5.67-22.94) and vertigo (RR: 1.92, 95% CI 1.16-3.17) at baseline. Multivariate analyses demonstrated that patients with high 3D-FLAIR signal intensity had 21 dB lower final hearing pure-tone averages (SMD: 21 dB, 95% CI 9.08-33.24). CONCLUSIONS: Three-dimensional fluid-attenuated inversion recovery MR imaging can identify an underlying labyrinthine condition in up to 29% of patients with sudden hearing loss in whom previously no cause could be identified. Their final pure-tone averages are more than 20 dB worse than 3D-FLAIR-negative patients, suggesting more severe labyrinthine damage. Findings such as these may contribute to our understanding of pathophysiologic mechanisms of ISSNHL.

OBJECTIVE: Cochlear implantation can result in post-operative vestibular dysfunction of unknown clinical significance. The objective of this study was to characterize the presence, magnitude, and clinical significance of vestibular dysfunction that occurs after pediatric cochlear implantation. DATA SOURCES: The databases Embase, Medline (OvidSP), and PubMed were used. Only articles published in English were included. Grey literature and unpublished sources were also reviewed. STUDY SELECTION: Articles published from 1980 until the present which documented pre-operative and post-operative vestibular testing on children under the age of 18 were used. DATA EXTRACTION: Parameters that were assessed included number of patients, pre- and post-operative vestibular-evoked myogenic potentials (VEMPs), head impulse testing (HIT), calorics, and posturography, timing of pre- and post-operative testing, symptomatology, and other demographic data such as etiology of the hearing loss. DATA SYNTHESIS: Ten articles were included. Relative risk values evaluating the effect of cochlear implantation on vestibular function were calculated for VEMPs and caloric testing due to the availability of published data. I2 values were calculated and 95% confidence intervals were reported. Separate analyses were conducted for each individual study and a pooled analysis was conducted to yield an overall relative risk. Assessment on risk of bias in individual studies and overall was performed. CONCLUSION: Pediatric cochlear implantation is associated with a statistically significant decrease in VEMP responses post-operatively (RR 1.8, p < 0.001, I2 91.86, 95%CI 1.57-2.02). Similar results are not seen in caloric testing. Insufficient data is available for analysis of HIT and posturography. Further studies are necessary to determine the effect of cochlear implantation on objective vestibular measures post-operatively and whether any changes seen are clinically relevant in this population.

Subjective complaints of dizziness after mild-to-moderate traumatic brain injury are common. Alterations in the mode of injury have changed the presentation symptoms. Evolutions in neuroimaging challenge conventional concepts regarding lack of evidence of injury following mild head trauma and provide hope for elucidating the site of lesion in patients with post-traumatic balance symptoms. Yet the vestibular clinician must maintain a healthy level of suspicion regarding potential exaggeration of symptoms and disability in patients with a financial incentive. Unique conditions warrant particular attention by the vestibular clinician, including chronic traumatic encephalopathy, catastrophization, and persistent postural and perceptual dizziness. The clinical significance of abnormalities, particularly on vestibular-evoked myogenic potential testing, needs to be better defined prior to their widespread application in the medical legal arena. The role of the medical expert is to provide opinion on matters requiring special knowledge to assist the court in reaching its findings. As such, this chapter provides an update on recent advances to consider in patients with dizziness after trauma.

Purpose of Chapter: This chapter highlights the recent advances in etiology, diagnostic evaluation, and management of vestibular neuritis (VN). Recent Findings: The viral hypothesis has been strengthened with new evidence as the main etiology of VN. Recent evidence indicates that bedside oculomotor findings play a critical role in differentiating VN from stroke. The implementation of cervical and ocular vestibular evoked myogenic potential, and video head impulse test in vestibular function testing has made it possible to diagnose selective damage of the vestibular nerves. The management of the acute phase of VN is primarily medical, while long-term treatment is designed to improve vestibular compensation. Summary: VN is clearly defined as an important viral inner ear disorder.

BACKGROUND: Patients with vestibular schwannomas (VS) are faced with complex management decisions. Watchful waiting, surgical resection, and radiation are all viable options with associated risks and benefits. We sought to determine if patients with VS experience decisional conflict when deciding between surgery or non-surgical management, and factors influencing the degree of decisional conflict. METHODS: A prospective cohort study in two tertiary ambulatory skull-base clinics was performed. Patients with newly diagnosed or newly growing vestibular schwannomas were recruited. Patients were given a demographic form and the decisional conflict scale (DCS), a validated measure to assess the degree of uncertainty when making medical decisions. The degree of shared decision making (SDM) experienced by the patient and physician were assessed via the SDM-Q-10 and SDM-Q-Doc questionnaires, respectively. Non-parametric statistics were used. Questionnaires and demographic information were correlated with DCS using Spearman correlation coefficient and Mann-Whitney U. Logistic regression was performed to determine factors independently associated with DCS scores. RESULTS: Seventy-seven patients participated (55% female, aged 37-81 years); VS ranged in size from 2 mm-50 mm. Significant decisional conflict (DCS score 25 or greater) was experienced by 17 (22%) patients. Patients reported an average SDM-Q-10 score of 86, indicating highly perceived level of SDM. Physician and patient SDM scores were weakly correlated (p = 0.045, Spearman correlation coefficient 0.234). DCS scores were significantly negatively correlated with a decision to pursue surgery, presence of a trainee, and higher SDM-Q-10 score. DCS was higher with female gender. Using logistic regression, the SDM-Q-10 score was the only variable associated with significantly reduced DCS. CONCLUSIONS: About one fifth of patients deciding how to manage their vestibular schwannoma experienced a significant degree of decisional conflict. Involving the patients in the process through shared decision-making significantly reduced the degree of uncertainty patients experienced.

BACKGROUND: There is a prevailing opinion that spinning sensations signify a peripheral vestibular pathology while non-spinning sensations are not of vestibular origin. OBJECTIVES: 1) Characterize the subjective sensations reported by patients during caloric testing. 2) Assess if the sensation was correlated with the peak slow phase velocity (SPV). METHODS: Retrospective chart review at a Canadian adult tertiary-quaternary care balance centre for patients undergoing diagnostic caloric testing between December 2014 and September 2015. RESULTS: Of 163 patients included, 122 had normal calorics and 41 demonstrated unilateral weakness. Spinning/rotatory movements were the most commonly reported sensations (55-70%). No sensation was reported among 10-20% of patients. Other non-rotatory sensations were reported 20-25% of the time. Both lack of sensation and other sensations were more likely to be correlated with SPVs that were significantly lower than those associated with spinning/rotating sensations. However, 18% of patients with normal calorics and robust SPVs with warm irrigation still reported non-spinning sensations. CONCLUSIONS: During caloric irrigation, subjective sensations other than spinning and rotating are reported 20-25% of the time and these tend to be associated with lower peak SPV. Non-spinning vertigo is not uncommon as a subjective description of vestibular sensation even in normal patients with strong SPVs.

OBJECTIVE: To review three patients with concurrent otosclerosis and superior canal dehiscence identified before operative intervention and provide a practical diagnostic approach to this clinical scenario. STUDY DESIGN: Retrospective patient series. SETTING: Tertiary/quaternary referral center. PATIENTS: Individuals with confirmed diagnoses of concurrent otosclerosis and superior semicircular canal dehiscence syndrome. INTERVENTIONS: Detailed history and physical examinations were performed on these patients, as well as detailed audiovestibular testing and computed tomography imaging. MAIN OUTCOME MEASURES: Establishing a clear diagnosis of concurrent otosclerosis and superior semicircular canal dehiscence syndrome using a thorough diagnostic approach. RESULTS: Three patients presented with conductive hearing loss and normal tympanic membranes. When history and physical examination yielded suspicious third window symptoms/signs, more detailed audiovestibular testing and computed tomography scan imaging were performed. All three patients were ultimately identified to have concurrent otosclerosis and superior canal dehiscence. Conservative management was the option of choice for two of these patients (trial of a hearing aid) and surgical intervention was performed to treat the otosclerosis in the remaining patient.

BACKGROUND: Noise-induced hearing loss is one of the most common forms of sensorineural hearing loss, is a major health problem, is largely preventable and is probably more widespread than revealed by conventional pure tone threshold testing. Noise-induced damage to the cochlea is traditionally considered to be associated with symmetrical mild to moderate hearing loss with associated tinnitus; however, there is a significant number of patients with asymmetrical thresholds and, depending on the exposure, severe to profound hearing loss as well. MAIN BODY: Recent epidemiology and animal studies have provided further insight into the pathophysiology, clinical findings, social and economic impacts of noise-induced hearing loss. Furthermore, it is recently shown that acoustic trauma is associated with vestibular dysfunction, with associated dizziness that is not always measurable with current techniques. Deliberation of the prevalence, treatment and prevention of noise-induced hearing loss is important and timely. Currently, prevention and protection are the first lines of defence, although promising protective effects are emerging from multiple different pharmaceutical agents, such as steroids, antioxidants and neurotrophins. CONCLUSION: This review provides a comprehensive update on the pathophysiology, investigations, prevalence of asymmetry, associated symptoms, and current strategies on the prevention and treatment of noise-induced hearing loss.

BACKGROUND: Mental practice, the cognitive rehearsal of a task in the absence of overt physical movement, has been successfully used in teaching complex psychomotor tasks including sports and music, and recently, surgical skills. The objectives of this study were, 1) To develop and evaluate a mental practice protocol for mastoidectomy 2) To assess the immediate impact of mental practice on a mastoidectomy surgical task among senior OtolaryngologyâHead & Neck Surgery (OHNS) residents. METHOD: Three expert surgeons were interviewed using verbal protocol analysis to develop a mastoidectomy mental practice script. Twelve senior Residents from Canadian training programs were randomized into two groups. All Residents were video-recorded performing a baseline mastoidectomy in a temporal bone lab. The intervention group received mental practice training, while the control group undertook self-directed textbook study. All subjects were then video-recorded performing a second mastoidectomy. Changes in pre- and post-test scores using validated expert ratings, the Task Specific Evaluation of Mastoidectomy and the Global Evaluation of Mastoidectomy, were statistically analyzed. RESULTS: A mental practice script was successfully developed based on interviews of three expert surgeon-educators. Task Specific Evaluation and Global Evaluation scores increased in both the mental practice and textbook study groups; there was no significant difference between the two groups in the change in scores post-intervention. There was a high and statistically signficant correlation between evaluators on the outcome measures. CONCLUSIONS: We were not able to demonstrate a significant difference for the benefits of mental practice in mastoidectomy, possibly due to the sample size. However, mental practice is a surgical education tool which is portable, accessible, inexpensive and safe.
