Implantable Hearing Devices in Ontario: A Population-Based Study of Access to Care and Access to Devices.

INTRODUCTION: The prevalence of hearing loss in Canada is high, with many patients requiring implantable hearing devices (IHDs) as treatment for their disease severity. Despite this need, many eligible patients do not pursue these interventions. The objective of this study was to examine rates of IHD based on geographic location to understand locoregional variation in access to care. STUDY DESIGN: This was a retrospective population-based cohort study. SETTING: All hospitals in the Canadian province of Ontario. METHODS: Of all patients with IHD between April 1, 1992, and March 31, 2021, cochlear implants (CIs) (4,720) and bone-anchored hearing aids (BAHA) (1,125) cohorts were constructed. Place of residence was categorized based on Local Health Integrated Network (LHIN). Summary statistics for place of surgical institution based on LHIN at first surgery, name of institution of first surgery and "as the crow flies" distance (in km) between place of residence and surgical institution were calculated. Rate of implantations was calculated for LHIN regions based on number of surgeries per 1,000,000 persons/years. RESULTS: Toronto Central, Central, Central East, and Champlain regions had >10% of patients undergoing BAHA and CI. 1,019 (90.6%) and 4,232 (89.7%) of patients receiving BAHA and CI, respectively, resided in urban/suburban regions and 94 patients (8.4%) and 436 (9.2%) resided in rural regions. The median distance between residential location and the institution was 46.4 km (interquartile range [IQR], 18.9-103.6) and 44.7 km (IQR, 15.7-96.9) for BAHA and CI, respectively. From 1992 to 2021, the number of CI and BAHA performed across Ontario increased by 17 folds and 6 folds, respectively. CONCLUSION: This large comprehensive population study provides longitudinal insight into the access to care of IHD based on geographic factors. Our findings of the present population-based study indicate an overall increase in access to devices with disproportionate access to care based on geographic locations. Further work is needed to characterize barriers to IHD access to align with demands.

Approach to sialadenitis.

OBJECTIVE: To provide family physicians with a practical evidence-based approach to the management of patients with sialadenitis. SOURCES OF INFORMATION: MEDLINE and PubMed databases were searched for English-language research on sialadenitis and other salivary gland disorders, as well as for relevant review articles and guidelines published between 1981 and 2021. MAIN MESSAGE: Sialadenitis refers to inflammation or infection of the salivary glands and is a condition that can be caused by a broad range of processes including infectious, obstructive, and autoimmune. History and physical examination play important roles in directing management, while imaging is often useful to establish a diagnosis. Red flags such as suspected abscess formation, signs of respiratory obstruction, facial paresis, and fixation of a mass to underlying tissue should prompt urgent referral to head and neck surgery or a visit to the emergency department. CONCLUSION: Family physicians can play an important role in the diagnosis and management of sialadenitis. Prompt recognition and treatment of the condition can prevent the development of complications.

Approche de la sialadénite.

OBJECTIF: Proposer aux médecins de famille une approche pratique fondée sur des données probantes pour la prise en charge de patients souffrant de sialadénite. SOURCES DE L'INFORMATION: Une recension a été effectuée dans les bases de données MEDLINE et PubMed pour trouver des recherches publiées en anglais sur la sialadénite et d'autres troubles des glandes salivaires, ainsi que des revues et des lignes directrices pertinentes, publiées entre 1981 et 2021. MESSAGE PRINCIPAL: La sialadénite désigne une inflammation ou une infection des glandes salivaires; elle peut être causée par un large éventail de processus de nature infectieuse, obstructive et auto-immune. L'anamnèse et l'examen physique jouent un rôle important pour orienter la prise en charge, tandis que l'imagerie est souvent utile pour établir un diagnostic. Des signaux d'alerte comme la formation suspectée d'un abcès, des signes d'obstruction respiratoire, une parésie faciale et la fixation d'une masse aux tissus sous-jacents devraient inciter à faire une demande de consultation urgente en chirurgie de la tête et du cou, ou à recommander une visite au service d'urgence. CONCLUSION: Les médecins de famille peuvent jouer un rôle important dans le diagnostic et la prise en charge de la sialadénite. Une reconnaissance et un traitement rapides du problème peuvent prévenir la survenance de complications.

Hearing Loss and Dementia: A Population-Based Cohort Study.

INTRODUCTION: Hearing loss (HL) is considered a potentially modifiable risk factor for dementia. We aimed to examine the relationship between HL and incident dementia diagnosis in a province-wide population-based cohort study with matched controls. METHODS: Administrative healthcare databases were linked to generate a cohort of patients who were aged ≥40 years at their first claimed hearing amplification devices (HAD) between April 2007 and March 2016 through the Assistive Devices Program (ADP) (257,285 with claims and 1,005,010 controls). The main outcome was incident dementia diagnosis, ascertained using validated algorithms. Dementia incidence was compared between cases and controls using Cox regression. Patient, disease, and other risk factors were examined. RESULTS: Dementia incidence rates (per 1,000 person-years) were 19.51 (95% confidence interval [CI]: 19.26-19.77) and 14.15 (95% CI: 14.04-14.26) for the ADP claimants and matched controls, respectively. In adjusted analyses, risk of dementia was higher in ADP claimants compared with controls (hazard ratio [HR]: 1.10 [95% CI: 1.09-1.12, p < 0.001]). Subgroup analyses showed a dose-response gradient, with risk of dementia higher among patients with bilateral HADs (HR: 1.12 [95% CI: 1.10-1.14, p < 0.001]), and an exposure-response gradient, with increasing risk over time from April 2007-March 2010 (HR: 1.03 [95% CI: 1.01-1.06, p = 0.014]), April 2010-March 2013 (HR: 1.12 [95% CI: 1.09-1.15, p < 0.001]), and April 2013-March 2016 (HR: 1.19 [95% CI: 1.16-1.23, p < 0.001]). CONCLUSION: In this population-based study, adults with HL had an increased risk of being diagnosed with dementia. Given the implications of HL on dementia risk, understanding the effect of hearing interventions merits further investigation.

Hearing aid utilization in Ontario - a population based study.

BACKGROUND: Hearing loss is one of the most common sensory impairments and hearing aids are the most common unmet assistive device need among individuals with a disability. The benefits of hearing interventions are well-documented as they are known to deter the sequalae of hearing loss including social isolation, poor mental health, falls and cognitive decline. Identifying trends in hearing aid users can provide valuable information for improving access to hearing loss interventions. METHODS: Data were retrieved from ICES databases that were used to generate a cohort of 372,448 individuals in Ontario, Canada, who first claimed hearing aids between April 2007 and March 2018 through the Assistive Devices Program. RESULTS: The data indicated that the frequency distribution of hearing aids has steadily inclined since 2007. The mean age of hearing aid users was 70.25 ± 14.70 years and higher neighbourhood income quintile was associated with greater hearing aid use (p < 0.001). Most first claims occurred after visiting primary care physicians (70.60%) compared with otolaryngology (13.39%). An examination of clinical comorbidities revealed hypertension (63.41%), and diabetes (24.93%) to be the most common. Regression analysis demonstrated a positive associated between age and most comorbidities. Furthermore, higher neighbourhood income quintiles were associated with a reduced risk of having the examined comorbidities. CONCLUSIONS: This study examines patient demographics and clinical comorbidities in a cohort of hearing aid users in Ontario. The results identify associations between demographics and comorbidities that provide information relevant for improving access to hearing interventions and clinical decision-making in primary care.Implications for RehabilitationScreening for hearing loss (using an audiogram) in elderly individuals that manage multiple comorbidities, and any patient with significant risk factors for hearing loss (e.g., noise exposure history, prior ototoxic medications, prior head injury, history of ear surgery, family history of hearing loss) will identify deficits and direct appropriate hearing interventions.Improving access to care in low-income communities should include community-based education around expectation management and communication strategies to reinforce proper use and care of hearing devices.Geographic proximity to hearing testing facilities and hearing aid dispensaries is a significant barrier to hearing rehabilitation strategies.

How to identify balance disorders and reduce fall risk.

A multifactorial risk assessment, correction of hearing impairment, exercise, and an optimized home environment can help prevent imbalance-related falls.

The predictive power of geographic health care utilization for unintentional fatal fall rates.

BACKGROUND: Falls are the leading cause of fatal and nonfatal injuries among adults over 65 years old. The increase in fall mortality rates is likely multifactorial. With a lack of key drivers identified to explain rising rates of death from falls, accurate predictive modelling can be challenging, hindering evidence-based health resource and policy efforts. The objective of this work is to examine the predictive power of geographic utilization and longitudinal trends in mortality from unintentional falls amongst different demographic and geographic strata. METHODS: This is a nationwide, retrospective cohort study using the United States Centers for Disease Control (CDC) Web-based Injury Statistics Query and Reporting System (WISQARS) database. The exposure was death from an unintentional fall as determined by the CDC. Outcomes included aggregate and trend crude and age-adjusted death rates. Health care utilization, reimbursement, and cost metrics were also compared. RESULTS: Over 2001 to 2018, 465,486 total deaths due to unintentional falls were recorded with crude and age-adjusted rates of 8.42 and 7.76 per 100,000 population respectively. Comparing age-adjusted rates, males had a significantly higher age-adjusted death rate (9.89 vs. 6.17; p <  0.00001), but both male and female annual age-adjusted mortality rates are expected to rise (Male: + 0.25 rate/year, R2= 0.98; Female: + 0.22 rate/year, R2= 0.99). There were significant increases in death rates commensurate with increasing age, with the adults aged 85 years or older having the highest aggregate (201.1 per 100,000) and trending death rates (+ 8.75 deaths per 100,000/year, R2= 0.99). Machine learning algorithms using health care utilization data were accurate in predicting geographic age-adjusted death rates. CONCLUSIONS: Machine learning models have high accuracy in predicting geographic age-adjusted mortality rates from health care utilization data. In the United States from 2001 through 2018, adults aged 85+ years carried the highest death rate from unintentional falls and this rate is forecasted to accelerate.

Preoperative anesthesiology consult utilization in Ontario - a population-based study.

RATIONALE, AIMS AND OBJECTIVES: Physician consultations are a limited resource. Anesthesiologists provide anaesthesia during surgery and procedures, prepare patients for surgery in preoperative clinics, and provide postoperative care. This study sought to evaluate current consultation usage patterns, with an aim to determine possible opportunities for efficiency. METHOD: A retrospective comprehensive population-based cohort study was performed, evaluating all hospitals in the Canadian province of Ontario from 2002 to 2018. The main outcome measures were American Society of Anesthesiologists (ASA) classification of the patients, and whether the patients underwent surgery within 3 months following the anaesthesia consultation. RESULTS: A cohort of 2,023,499 patients, and a total of 2,920,100 preoperative anaesthesia consultations was obtained. The number of consults per year doubled between 2003 (112,983/year) and 2017 (246,427/year), despite a less than 40% increase in practicing Canadian Anesthesiologists over this same timeframe. Each year, an average of 19.3% of the consults (range: 17.7-20.5%) were for patients that did not progress to having surgery. Of those that did have surgery following the anaesthesia consult, 37.2% were ASA Classification I or II. The most common surgical procedures (percent of total) following anaesthesia consult were: Knee arthroplasty (9.5%), hip arthroplasty (5.8%), cataract extraction (4.1%), repair of muscle of chest/abdomen (3.3%), hysterectomy (2.8%), and cholecystectomy (2.7%). CONCLUSIONS: This study reveals data on utilization and trends over time of preoperative anaesthesia consultations. Potential opportunities for optimization were found, including patients who did not proceed to surgery, and healthier patients undergoing low to moderate risk surgery.

Repetitive Transcranial Magnetic Stimulation For The Treatment of Chronic Tinnitus: A Preliminary Study of The Influence of Traumatic Brain Injury on Treatment Response.

This study aims to test whether the efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) differs between patients who developed tinnitus following a traumatic brain injury (TBI), and those without a history of TBI. This was a parallel pilot, open-label, non-randomized, clinical trial to compare the efficacy of low frequency rTMS on tinnitus symptoms in patients with and without a TBI history. Patients with moderate to severe tinnitus symptoms based on the Tinnitus Handicap Inventory (THI) and the Tinnitus Functional Index (TFI) were enrolled in the study. Validated questionnaires (THI and TFI) were used to quantify the severity of tinnitus symptoms and hearing impairment (Hearing Handicap Index - HHI) before and after ten sessions of rTMS of the left primary auditory cortex. Hearing threshold levels as well as speech reception and speech discrimination thresholds were also compared. The number of patients who experienced a reduction in their subjective tinnitus symptoms was greater and sustained longer in patients without a history of TBI. The same was seen with subjective symptoms of hearing impairment. In conclusion, our preliminary results suggest tinnitus patients without a history of TBI respond better to low frequency rTMS than those with a history of TBI, suggesting that treatments could be more effective if tailored to tinnitus etiology.

Predictors of Postoperative Complications in Vestibular Schwannoma Surgery-A Population-Based Study.

OBJECTIVE: To investigate preoperative patient demographics and comorbidities in relation with postsurgical complications following vestibular schwannoma surgery. STUDY DESIGN: Retrospective population-based cohort study. SETTING: All hospitals in the Canadian province of Ontario. PATIENTS: This study includes 1,456 patients who underwent vestibular schwannoma surgery from April 1, 2002 to March 31, 2018 in Ontario, Canada. INTERVENTION/OUTCOME MEASURES: For all surgical patients, the demographic data, preoperative comorbidities, and postoperative complications were evaluated. Postoperative complications were examined immediately following surgery in the hospital as well as 1 year following the hospital discharge. RESULTS: The most common comorbidities in this cohort were hypertension (30.22%), diabetes (9.48%), asthma (13.53%), and chronic obstructive pulmonary disease (6.73%). Diabetes was the most impactful comorbidity and was associated with higher risk of myocardial infarction (RR = 4.58, p < 0.01), pneumonia (RR = 1.80, p = 0.02), dysphagia (RR = 1.58, p < 0.01), and meningitis (RR = 3.62, p < 0.01). Analysis of surgical approaches revealed that the translabyrinthine approach, compared with the open craniotomy approach, was negatively associated with postoperative complications including pneumonia (RR = 0.43, p < 0.01), urinary tract infection (RR = 0.55, p = 0.01), dysphagia (RR = 0.66, p < 0.01), and readmission (RR = 0.45, p < 0.01). CONCLUSION: This study examines patient demographics, preoperative comorbidities, and postoperative complications in patients who have undergone vestibular schwannoma surgery. The results highlight associations between patient characteristics and postoperative outcomes that can aid in preoperative decision-making and counselling.

Approach to hearing loss.

OBJECTIVE: To provide family physicians with a practical evidence-based approach to the management of patients with hearing loss. SOURCES OF INFORMATION: MEDLINE and PubMed databases were searched for English-language hearing loss research, review articles, and guidelines published between 1980 and 2020. Most of the retrieved articles provided level II or III evidence. MAIN MESSAGE: Hearing loss is one of the most common sensory impairments worldwide and causes great detriment to a patient's overall well-being by affecting physical health, finances, social inclusion, and mental health. A robust clinical assessment of hearing loss includes a history and physical examination that effectively characterizes the deficit as conductive, sensorineural, or mixed. Patients presenting with red flags (such as sudden unilateral sensorineural hearing loss) must be urgently referred to otolaryngology-head and neck surgery or immediately assessed in the emergency department. Many nonurgent presentations of hearing loss will also require referral for further audiological assessment, diagnosis, and management. CONCLUSION: As primary care providers, family physicians are well equipped to manage the psychological concerns associated with hearing loss and to reinforce conservative treatment strategies. Frequently, referral or urgent workup, including imaging, is necessary to confirm a patient's diagnosis and initiate management in order to prevent further complications.

Aborder la perte auditive.

OBJECTIF: Fournir aux médecins de famille une approche pratique et fondée sur des données probantes pour la prise en charge de la perte auditive. SOURCES D'INFORMATION: Une recherche dans les bases de données MEDLINE et PubMed a relevé les revues de synthèse, recherches et lignes directrices publiées en anglais de 1980 à 2020. Les données probantes étaient de niveau II ou III dans la plupart des articles relevés. MESSAGE PRINCIPAL: La perte auditive est l'une des déficiences sensorielles les plus fréquentes dans le monde, et elle est grandement préjudiciable au bien-être général du patient, affectant sa santé physique, ses finances, son inclusion sociale et sa santé mentale. Une solide évaluation clinique de la perte auditive comprend une anamnèse et un examen physique qui caractérisent efficacement la perte auditive comme étant de transmission, neurosensorielle ou mixte. Les patients qui présentent des signes alarmants (comme une perte auditive neurosensorielle unilatérale soudaine) doivent être aiguillés d'urgence en oto-rhino-laryngologie et chirurgie cervico-faciale ou être évalués immédiatement au service des urgences. Beaucoup de cas non urgents de perte auditive nécessitent également une évaluation audiologique plus poussée, un diagnostic et la prise en charge. CONCLUSION: À titre de fournisseurs de soins de première ligne, les médecins de famille sont bien placés pour gérer les préoccupations psychologiques liées à la perte auditive et pour renforcer les stratégies thérapeutiques prudentes. Il est fréquemment nécessaire d'aiguiller le patient ou d'effectuer un bilan urgent, dont l'imagerie, pour confirmer le diagnostic et instaurer la prise en charge afin de prévenir d'autres complications.

Evaluating the effectiveness of learning ear anatomy using holographic models.

BACKGROUND: Computer-assisted learning has been shown to be an effective means of teaching anatomy, with 3-D visualization technology more successfully improving participants' factual and spatial knowledge in comparison to traditional methods. To date, however, the effectiveness of teaching ear anatomy using 3-D holographic technology has not been studied. The present study aimed to evaluate the feasibility and effectiveness of learning ear anatomy using a holographic (HG) anatomic model in comparison to didactic lecture (DL) and a computer module (CM). METHODS: A 3-D anatomic model of the middle and inner ear was created and displayed using presentation slides in a lecture, computer module, or via the Microsoft HoloLens. Twenty-nine medical students were randomized to one of the three interventions. All participants underwent assessment of baseline knowledge of ear anatomy. Immediately following each intervention, testing was repeated along with completion of a satisfaction survey. RESULTS: Baseline test scores did not differ across intervention groups. All groups showed an improvement in anatomic knowledge post-intervention (p < 0.001); the improvement was equal across all interventions (p = 0.06). Participants rated the interventions equally for delivery of factual content (p = 0.96), but rated the HG higher than the DL and CM for overall effectiveness, ability to convey spatial relationships, and for learner engagement and motivation (p < 0.001). CONCLUSIONS: These results suggest that 3-D holographic technology is an effective method of teaching ear anatomy as compared to DLs and CMs. Furthermore, it is better at engaging and motivating learners compared to traditional methods, meriting its inclusion as a tool in undergraduate medical education curriculum.

Long-Term Incidence and Predictors of Significant Hearing Loss Requiring Hearing Assistive Devices Among Childhood Cancer Survivors: A Population-Based Study.

PURPOSE: Hearing loss is a significant late effect among childhood cancer survivors. Recent guidelines note insufficient evidence to quantify its natural history or risk associated with specific exposures. We examined the long-term incidence and predictors of hearing loss requiring hearing amplification devices (HADs) using population-based health care data. METHODS: In Ontario, Canada, HAD costs are subsidized by the Assistive Devices Program (ADP). Ontario children < 18 years of age at cancer diagnosis between 1987 and 2016 were identified and linked to ADP claims. Cumulative HAD incidence was compared between cases and matched controls. Patient, disease, and treatment predictors of HAD were examined. RESULTS: We identified 11,842 cases and 59,210 controls. Cases were at higher risk for HAD (hazard ratio [HR], 12.8; 95% CI, 9.8 to 16.7; P < .001). The cumulative incidence of HAD among survivors was 2.1% (95% CI, 1.7% to 2.5%) at 20 years and 6.4% (95% CI, 2.8% to 12.1%) at 30 years post-diagnosis. The 30-year incidence was highest in neuroblastoma (10.7%; 95% CI, 3.8% to 21.7%) and hepatoblastoma (16.2%; 95% CI, 8.6% to 26.0%) survivors. Predictors of HAD in multivariable analyses included age 0-4 years at diagnosis (v 5-9 years; HR, 2.2; 95% CI, 1.4-3.3; P < .001). Relative to no cisplatin exposure, patients receiving < 200 mg/m2 were not at greater risk, unlike those receiving higher cumulative doses. Relative to no cranial or facial radiation, those who had received ≤ 32.00 Gy were at no higher risk, unlike those who had received > 32.00 Gy. Carboplatin exposure was not associated with HAD. CONCLUSION: Childhood cancer survivors are at elevated risk for requiring HAD, which continues to increase between 20 and 30 years after diagnosis. Thresholds of cisplatin and radiation exposure exist, above which risk substantially increases. Prolonged monitoring and trials of otoprotective agents are warranted in high-risk populations.

Pharyngitis: Approach to diagnosis and treatment.

OBJECTIVE: To provide family physicians with an updated approach to diagnosis and treatment of pharyngitis, detailing key symptoms, methods of investigation, and a summary of common causes. SOURCES OF INFORMATION: The approach described is based on the authors' clinical practice and peer-reviewed literature from 1989 to 2018. MAIN MESSAGE: Sore throat caused by pharyngitis is commonly seen in family medicine clinics and is caused by inflammation of the pharynx and surrounding tissues. Pharyngitis can be caused by viral, bacterial, or fungal infections. Viral causes are often self-limiting, while bacterial and fungal infections typically require antimicrobial therapy. Rapid antigen detection tests and throat cultures can be used with clinical findings to identify the inciting organism. Pharyngitis caused by Streptococcus pyogenes is among the most concerning owing to its associated severe complications such as acute rheumatic fever and glomerulonephritis. Hence, careful diagnosis of pharyngitis is necessary to provide targeted treatment. CONCLUSION: A thorough history is key to diagnosing pharyngitis. Rapid antigen detection tests should be reserved for concerns about antibiotic initiation. Physicians should exercise restraint in antibiotic initiation for pharyngitis, as restraint does not delay recovery or increase the risk of S pyogenes infections.

Pharyngite: Approche diagnostique et thérapeutique.

OBJECTIF: Offrir aux médecins de famille une approche diagnostique et thérapeutique actualisée de la pharyngite, en décrivant en détail les principaux symptômes, les méthodes d'investigation et un résumé des causes courantes. SOURCES D'INFORMATION: L'approche décrite est basée sur la pratique clinique des auteurs et sur les publications revues par les pairs de 1989 à 2018. MESSAGE PRINCIPAL: Le mal de gorge causé par la pharyngite est couramment observé dans les cliniques de médecine familiale; il est causé par l'inflammation du pharynx et des tissus environnants. La pharyngite est causée par une infection virale, bactérienne ou fongique. Les causes virales sont souvent spontanément résolutives, alors que les infections bactériennes et fongiques nécessitent habituellement l'antibiothérapie. Le test de détection rapide de l'antigène et la culture de gorge sont jumelés aux observations cliniques pour identifier l'organisme en cause. La pharyngite causée par streptococcus pyogenes fait partie des organismes les plus préoccupants en raison de ses complications graves, telles la fièvre rhumatismale aiguë et la glomérulonéphrite. Ainsi, il est nécessaire de poser un diagnostic attentif de pharyngite afin de pouvoir dispenser un traitement ciblé. CONCLUSION: L'anamnèse détaillée est la clé du diagnostic de pharyngite. Le test de détection rapide de l'antigène doit être réservé aux cas où l'instauration de l'antibiothérapie est préoccupante. Les médecins doivent user de retenue lorsqu'ils instaurent l'antibiothérapie contre la pharyngite, puisque la retenue ne retarde pas le rétablissement ni n'augmente le risque d'infection à s. pyogenes.

Association of tympanostomy tubes with future assistive hearing devices-a population based study.

BACKGROUND: Ear (tympanostomy) tube (TT) placement is a common ambulatory surgery in children. Despite the commonality of this treatment, the long-term effects are unknown. The objective of this study was to determine the rate of permanent hearing loss, as measured by use of a rehabilitative hearing device. METHODS: A retrospective comprehensive population-based cohort study was performed, evaluating all hospitals in the Canadian province of Ontario. Three cohorts of children were constructed: TT - at least one ear tube procedure (n = 193,880), No-TT -recurrent visits to a physician for middle ear disease, did not undergo ear tubes (n = 203,283), and Control - an age/sex matched group who had not undergone ear tubes and who didn't have repeat physician visits for middle ear disease (n = 961,168). The main outcome measures were risk and odds ratio (OR) of rehabilitative hearing devices. RESULTS: The TT cohort had a higher risk of obtaining a hearing aid (OR 4.53 vs. No-TT, p < 0.001; OR 10.81 vs. Control, p < 0.001), an FM system (OR 3.84 vs. No-TT, p < 0.001; OR 15.13 vs. Control, p < 0.001), and an implanted bone conduction device (OR 5.08 vs. No-TT, p < 0.001; OR 15.67 vs. Control, p < 0.001). CONCLUSIONS: An association between ear tube placement and long-term need for a rehabilitative hearing device was found. This association warrants future prospective research in this area.

Cerumen Management: An Updated Clinical Review and Evidence-Based Approach for Primary Care Physicians.

Objective: To provide family physicians with a practical, evidence-based approach to managing patients with cerumen impaction. Methods: MEDLINE, The Cochrane Library, and the Turning Research Into Practice (TRIP) database were searched for English-language cerumen impaction guidelines and reviews. All such articles published between 1992 and 2018 were reviewed, with most providing level II and III evidence. Results: Cerumen impaction is a common presentation seen in primary care and cerumen removal is one of the most common otolaryngologic procedures performed in general practice. Cerumen impaction is often harmless but can be accompanied by more serious symptoms. Cerumenolytics and irrigation of the ear canal are reasonable first-line therapies and can be used in conjunction or isolation. If irrigation and cerumenolytics are contraindicated, manual removal is appropriate, but the tools necessary are not commonplace in primary care clinics and specialized training may be required to prevent adverse outcomes. Conclusion: Family physicians play a key role in the assessment and management of cerumen impaction and are well equipped to do so. Knowledge of the available techniques for cerumen removal as well as their contraindications ensures that cerumen is removed safely and effectively. When cerumen removal cannot be removed safely in a primary care setting, referral to Otolaryngology-Head and Neck Surgery is appropriate.
