RESUMO

Significance: Pathologies within the tympanic membrane (TM) and middle ear (ME) can lead to hearing loss. Imaging tools available in the hearing clinic for diagnosis and management are limited to visual inspection using the classic otoscope. The otoscopic view is limited to the surface of the TM, especially in diseased ears where the TM is opaque. An integrated optical coherence tomography (OCT) otoscope can provide images of the interior of the TM and ME space as well as an otoscope image. This enables the clinicians to correlate the standard otoscopic view with OCT and then use the new information to improve the diagnostic accuracy and management. Aim: We aim to develop an OCT otoscope that can easily be used in the hearing clinic and demonstrate the system in the hearing clinic, identifying relevant image features of various pathologies not apparent in the standard otoscopic view. Approach: We developed a portable OCT otoscope device featuring an improved field of view and form-factor that can be operated solely by the clinician using an integrated foot pedal to control image acquisition. The device was used to image patients at a hearing clinic. Results: The field of view of the imaging system was improved to a 7.4 mm diameter, with lateral and axial resolutions of 38 µ m and 33.4 µ m , respectively. We developed algorithms to resample the images in Cartesian coordinates after collection in spherical polar coordinates and correct the image aberration. We imaged over 100 patients in the hearing clinic at USC Keck Hospital. Here, we identify some of the pathological features evident in the OCT images and highlight cases in which the OCT image provided clinically relevant information that was not available from traditional otoscopic imaging. Conclusions: The developed OCT otoscope can readily fit into the hearing clinic workflow and provide new relevant information for diagnosing and managing TM and ME disease.

RESUMO

PURPOSE: Tympanostomy tube (TT) placement is the most frequently performed ambulatory surgery in children under 15. After the procedure it is recommended that patients follow up regularly for "tube checks" until TT extrusion. Such visits incur direct and indirect costs to families in the form of days off from work, copays, and travel expenses. This pilot study aims to compare the efficacy of tympanic membrane (TM) evaluation by an artificial intelligence algorithm with that of clinical staff for determining presence or absence of a tympanostomy tube within the TM. METHODS: Using a digital otoscope, we performed a prospective study in children (ages 10 months-10 years) with a history of TTs who were being seen for follow up in a pediatric otolaryngology clinic. A smartphone otoscope was used by study personnel who were not physicians to take ear exam images, then through conventional otoscopic exam, ears were assessed by a clinician for tubes being in place or tubes having extruded from the TM. We trained and tested a deep learning (artificial intelligence) algorithm to assess the images and compared that with the clinician's assessment. RESULTS: A total of 123 images were obtained from 28 subjects. The algorithm classified images as TM with or without tube in place. Overall classification accuracy was 97.7 %. Recall and precision were 100 % and 96 %, respectively, for TM without a tube present, and 95 % and 100 %, respectively, for TM with a tube in place. DISCUSSION: This is a promising deep learning algorithm for classifying ear tube presence in the TM utilizing images obtained in awake children using an over-the-counter otoscope available to the lay population. We are continuing enrollment, with the goal of building an algorithm to assess tube patency and extrusion.

RESUMO

PURPOSE: To investigate the utility of a hand-held digital otoscope for nasal endoscopy and as a pedagogy tool for residents and fellows in patients undergoing external dacryocystorhinostomy (DCR) surgery. METHODS: A digital otoscope (MS450-NTE, Teslong Inc., USA) comprising a digital screen device and a connectible camera probe was used for performing nasal endoscopy. Inspection of nasal cavities was performed pre-, intra-, and post-operatively in sequential patients with nasolacrimal duct obstruction, who underwent DCR or lacrimal probing. Images (1920 × 1080 pixels) and videos (1280 × 720 pixels) were captured. The device was also used for training residents and fellows in performing nasal endoscopy, and to teach basic concepts. RESULTS: The digital otoscope could be used for routine outpatient nasal examination and for performing minor procedures. 53.8% (n = 13) of ophthalmology trainees had never observed nasal endoscopy and 84.6% could not identify more than one major structure correctly prior to the current training. Post-training, all trainees could independently perform nasal endoscopy with the device and 76.9% identified all structures correctly. CONCLUSION: A digital otoscope with a camera probe is a handy tool for nasal endoscopy and pedagogy. Low-cost gadgets such as this device can effectively be used for performing outpatient nasal endoscopy when expensive endoscopes are unavailable and in peripheral healthcare centers.

RESUMO

OBJECTIVE: The COVID-19 pandemic has spurred a growing demand for telemedicine. Artificial intelligence and image processing systems with wireless transmission functionalities can facilitate remote care for otitis media (OM). Accordingly, this study developed and validated an algorithm-driven tele-otoscope system equipped with Wi-Fi transmission and a cloud-based automatic OM diagnostic algorithm. STUDY DESIGN: Prospective, cross-sectional, diagnostic study. SETTING: Tertiary Academic Medical Center. METHODS: We designed a tele-otoscope (Otiscan, SyncVision Technology Corp) equipped with digital imaging and processing modules, Wi-Fi transmission capabilities, and an automatic OM diagnostic algorithm. A total of 1137 otoscopic images, comprising 987 images of normal cases and 150 images of cases of acute OM and OM with effusion, were used as the dataset for image classification. Two convolutional neural network models, trained using our dataset, were used for raw image segmentation and OM classification. RESULTS: The tele-otoscope delivered images with a resolution of 1280 × 720 pixels. Our tele-otoscope effectively differentiated OM from normal images, achieving a classification accuracy rate of up to 94% (sensitivity, 80%; specificity, 96%). CONCLUSION: Our study demonstrated that the developed tele-otoscope has acceptable accuracy in diagnosing OM. This system can assist health care professionals in early detection and continuous remote monitoring, thus mitigating the consequences of OM.

RESUMO

OBJECTIVES: Performing pediatric otoscopy can be difficult secondary to patient compliance, which potentiates misdiagnosis and inaccurate treatment of acute otitis media. This study used a convenience sample to assess the feasibility of using a video otoscope for the examination of tympanic membranes in children presenting to a pediatric emergency department. METHODS: We obtained otoscopic videos using the JEDMED Horus + HD Video Otoscope. Participants were randomized to video or standard otoscopy, and a physician completed their bilateral ear examinations. In the video group, physicians reviewed otoscope videos with the patient's caregiver. The caregiver and physician completed separate surveys using a 5-point Likert Scale regarding perceptions of the otoscopic examination. A second physician reviewed each otoscopic video. RESULTS: We enrolled 213 participants in 2 groups (standard otoscopy, n = 94; video otoscopy, n = 119). We used Wilcoxon rank sum, Fisher exact test, and descriptive statistics to compare results across groups. For physicians, there were no statistically significant differences between groups with ease of device use, quality of otoscopic view, or diagnosis. There was moderate agreement between physician video otoscopic view satisfaction and slight agreement between physician video otologic diagnosis. Estimates of length of time to complete the ear examinations were longer more often for the video otoscope compared with standard for both caregivers (OR, 2.00; 95% confidence interval, 1.10-3.70; P = 0.02) and physicians (OR, 3.08; 95% confidence interval, 1.67-5.78; P < 0.01). There were no statistically significant differences between video and standard otoscopy with regard to caregiver perception of comfort, cooperation, satisfaction, or diagnosis understanding. CONCLUSIONS: Caregivers perceive that video otoscopy and standard otoscopy are comparable in comfort, cooperation, examination satisfaction, and diagnosis understanding. Physicians made a wider range of more subtle diagnoses with the video otoscope. However, examination length of time may limit the JEDMED Horus + HD Video Otoscope's feasibility in a busy pediatric emergency department.

RESUMO

OBJECTIVE: The video otoscope has already proven to be useful for the diagnosis of several pathologies, so the objective of this study was to evaluate the diagnostic accuracy of the video otoscope in cases of tympanic membrane perforation. METHODS: This is a diagnostic accuracy study performed at the hearing health division of a tertiary-level referral hospital. Patients older than 8 years of age who had any symptom that could be related to perforation (otalgia, otorrhea, tinnitus, and/or hypoacusis) were invited to participate in the study. Participants were evaluated by three different diagnostic methods (otomicroscope, conventional otoscope, and video otoscope) performed by three different evaluators in a blind fashion. The microscope was considered the reference standard. RESULTS: 176 patients were evaluated, totaling 352 tympanic membranes. Twenty-seven tympanic membrane perforations were diagnosed by the microscope, a prevalence of 7.7%. The video otoscope showed a sensitivity of 85.2% (95% CI 81.5%‒88.9%), specificity of 98.1% (95% CI 96.7%‒99.5%) and accuracy of 97.1% (95% CI 95.4 %-98.8 %). The conventional otoscope showed a sensitivity of 96.3% (95% CI 94.3-98.3), specificity of 98.8% (95% CI 97.7-99.9) and accuracy of 98.6% (95% CI 97.4-99.8). The Kappa value between the microscope and the video otoscope was 0.8 and between the microscope and the conventional otoscope was 0.9. Regarding the participants' perception, 53.4% (p< 0.001) considered the video otoscope as the best method for understanding the tympanic membrane condition presented by them. CONCLUSIONS: The video otoscope showed relevant sensitivity and specificity for clinical practice in the diagnosis of tympanic membrane perforation. Moreover, this is an equipment that can facilitate the patient's understanding of the otologic pathology presented by him/her. In this regard, this method may be important for better patient compliance, requiring further studies to evaluate this hypothesis. LEVEL OF EVIDENCE: Is this diagnostic or monitoring test accurate? (Diagnosis)-Level 2 (Individual cross-sectional studies with consistently applied reference standard and blinding).

RESUMO

OBJECTIVES: To assess the face, construct and content validity of three different platforms for otoscopy skills assessment, using a traditional otoscope with manikin, digital otoscope (Tympahealth) with manikin, and traditional otoscope with a low-cost model ear (SimEar). DESIGN: Prospective mixed methods study. SETTING: Tertiary hospital. PARTICIPANTS: Postgraduate trainees and expert assessors. MAIN OUTCOME MEASURES: Face and Content validity based on expert assessor ranking on each model and their feedback from semi-structured interviews. Construct validity based on Objective Structured Clinical Examination scores. RESULTS: Each platform differed in face, construct and content validity scores, with no one platform consistently outperforming others. Three main themes were identified during thematic analysis of expert assessor interviews: ability to assess what is seen, anatomical reality, and ease of use. The low-cost model showed greatest potential, where modification to include a silicone ear could lead to high validity with marginal increase in cost. CONCLUSION: Several modalities for assessing otoscopy skills exist, each with advantages and disadvantages. Modifications to a low-cost model, for use with either a traditional or digital otoscope, could prove to be the best model.

RESUMO

Purpose: This study aimed to evaluate the effectiveness of smartphone otoscope telemedicine in the rural medical consortium in East China in the COVID-19 era. Methods: This prospective study was conducted within a rural medical consortium that provides health care services by integrating medical resources in the same area. When a patient visited primary health care (PHC) for ear diseases, the PHC provider used a smartphone otoscope to examine the patient's external ear canal and eardrum, and then sent photos or videos of the patient's ear to the otolaryngologist at the lead hospital via WeChat group. The otolaryngologist provided remote diagnosis and management recommendations to the PHC provider. The following data were recorded: age and gender, outpatient diagnosis, disease duration, sides, duration of treatment, telemedicine visits, treatment outcomes, patient satisfaction, and PHC providers' self-evaluation score. Results: A total of 83 patients were included in the study, including 43 males and 40 females, with a mean age of 44.6 ± 19.7 years (range 3-83 years). The duration of treatment for these patients was 14.0 (7,14) days. PHC visits were 2.2 ± 1.1 times (range: 1-7 times). Telemedicine visits ranged from 1 to 5, with a mean of 1.8 ± 0.9. Among of patients, 62 (74.7%) were cured, 21 (25.3%) improved, and 0 (0%) were ineffective. Sixty-five patients (78.3%) were very satisfied, 16 (19.3%) patients were somewhat satisfied, and two patients (2.4%) were dissatisfied. Based on the self-reported helpfulness, the primary health care providers assessed telemedicine as very helpful (n = 63, 75.9%), helpful (n = 20, 24.1%), and unhelpful (n = 0, 0%). Conclusions: Smartphone otoscope telemedicine in the medical consortium can effectively improve the ability of rural PHC providers to diagnose and treat ear diseases, save time and costs for patients, and improve patient satisfaction.

RESUMO

Objective: To explore the feasibility and short-term effect of tensor tympani muscle Tenotomy in the treatment of Meniere's disease under otoscope. The possible pathogenesis was discussed and our views were put forward. Methods: The clinical data of 9 cases of Meniere's disease treated by otoscopic Tenotomy were analyzed retrospectively, including 2 males, 7 females, 5 right ones, 2 left ones and 2 bilateral ones. The average age was (56.33± 10.56) years, ranging from 38 to 75 years. We evaluated intraoperative findings and short-term postoperative efficacy, respectively evaluated postoperative aural fullness, tinnitus and hearing recovery, and evaluated postoperative vertigo attack in a short time. Results: Nine patients were completed the operation under general anaesthesia and otoscopy, and no serious complications occurred. We found new pathological changes in tympanic cavity in some cases during operation. There were rupture of round window membrane in 1 case, severe fibrous hyperplasia near the round window membrane and vestibular window and adhesion with ossicular chain in 1 case, fibrous cord and membranous hyperplasia near vestibular window and round window membrane in 1 case, fibrous hyperplasia and adhesion near the round window membrane in 2 cases, membranous hyperplasia and adhesion around vestibular window in 1 case. No fibrous hyperplasia was found in 3 cases in the tympanic cavity. The round window membrane can be exposed in 4 cases and failed in 5 cases. After 3 months of follow-up, we found that we found that 5/5 cases of aural fullness disappeared, 2/2 cases of earache disappeared, 3/8 cases of tinnitus improved, 5/8 cases presented with improvement and no aggravation, 3/3 cases of hearing allergy improved, 4/9 cases of hearing improved, and 5/9 cases showed no improvement or decrease. 9 patients were followed up for 3 months, of whom 8 patients had no vertigo, one patient suffered from vertigo twice within 3 months after operation, and the patient suffered from rupture of round window membrane. Conclusions: Endoscopic Tenotomy for Meniere's disease has obvious curative effect and quick recovery after operation. During the operation, we find that most of Meniere's patients have fibrous cord hyperplasia near the inner ear window membrane, which may be the pathological manifestation after repeated rupture and repair of the inner ear window membrane. The vertigo of Meniere's disease may be related to the destruction and repair of inner ear membrane structure caused by improper contraction or spasm of tympanic tensor muscle.

RESUMO

Examining a child's tympanic membrane (TM) is challenging, but crucial for proper management of acute otitis media (AOM). CellScope Oto (CSO) is an attachment that turns a smartphone into an otoscope. We aimed to assess pediatric resident comfort level with ear exams using CSO to see whether comfort level and accuracy of diagnosis of AOM improved. A pre-post study of pediatric residents in a freestanding Pediatric Emergency Department was conducted to assess their comfort level of traditional otoscope and CSO via a Likert scale. Ear exams were recorded and rated by 2 faculty for accuracy of AOM diagnosis. A total of 18 pediatric residents participated, and 308 exams were collected, with 2% diagnosed as AOM. The median change in comfort level increased by +1.0 for interns and third years but remained unchanged for second years. There was substantial agreement by faculty raters of video ear exams. Overall, comfort level increased with accuracy of diagnosis of AOM.

RESUMO

OBJECTIVES: To summarise the accuracy of artificial intelligence (AI) computer vision algorithms to classify ear disease from otoscopy. DESIGN: Systematic review and meta-analysis. METHODS: Using the PRISMA guidelines, nine online databases were searched for articles that used AI computer vision algorithms developed from various methods (convolutional neural networks, artificial neural networks, support vector machines, decision trees and k-nearest neighbours) to classify otoscopic images. Diagnostic classes of interest: normal tympanic membrane, acute otitis media (AOM), otitis media with effusion (OME), chronic otitis media (COM) with or without perforation, cholesteatoma and canal obstruction. MAIN OUTCOME MEASURES: Accuracy to correctly classify otoscopic images compared to otolaryngologists (ground truth). The Quality Assessment of Diagnostic Accuracy Studies Version 2 tool was used to assess the quality of methodology and risk of bias. RESULTS: Thirty-nine articles were included. Algorithms achieved 90.7% (95%CI: 90.1-91.3%) accuracy to difference between normal or abnormal otoscopy images in 14 studies. The most common multiclassification algorithm (3 or more diagnostic classes) achieved 97.6% (95%CI: 97.3-97.9%) accuracy to differentiate between normal, AOM and OME in three studies. AI algorithms outperformed human assessors to classify otoscopy images achieving 93.4% (95%CI: 90.5-96.4%) versus 73.2% (95%CI: 67.9-78.5%) accuracy in three studies. Convolutional neural networks achieved the highest accuracy compared to other classification methods. CONCLUSION: AI can classify ear disease from otoscopy. A concerted effort is required to establish a comprehensive and reliable otoscopy database for algorithm training. An AI-supported otoscopy system may assist health care workers, trainees and primary care practitioners with less otology experience identify ear disease.

RESUMO

OBJECTIVES: This study aims to investigate the inter-rater reliability and agreement of the diagnosis of otitis media with effusion, acute otitis media, and no effusion cases based on an otoscopy image and in some cases an additional wideband tympanometry measurement of the patient. METHODS: 1409 cases were examined and diagnosed by an otolaryngologist in the clinic, and otoscopy examination and wideband tympanometry (WBT) measurement were conducted. Afterwards, four otolaryngologists (Ear, Nose, and Throat doctors, ENTs), who did not perform the acute examination of the patients, evaluated the otoscopy images and WBT measurements results for diagnosis (acute otitis media, otitis media with effusion, or no effusion). They also specified their diagnostic certainty for each case, and reported whether they used the image, wideband tympanometry, or both, for diagnosis. RESULTS: All four ENTs agreed on the diagnosis in 57% of the cases, with a pairwise agreement of 74%, and a Light's Kappa of 0.58. There are, however, large differences in agreement and certainty between the three diagnoses. Acute otitis media yields the highest agreement (77% between all four ENTs) and certainty (0.90), while no effusion shows much lower agreement and certainty (34% and 0.58, respectively). There is a positive correlation between certainty and agreement between the ENTs across all cases, and both certainty and agreement increase for cases where a WBT measurement is shown in addition to the otoscopy image. CONCLUSIONS: The inter-rater reliability between four ENTs was high when diagnosing acute otitis media and lower when diagnosing otitis media with effusion. However, WBT can add valuable information to get closer to the ground-truth diagnosis without myringotomy. Furthermore, the diagnostic certainty increases when the WBT is examined together with the otoscopy image.

RESUMO

The smartphone enabled otoscope (SEO) provides an opportunity for telemedicine and enhancing teaching of otoscopy. We describe our preliminary experience with the use of one such inexpensive device bought from an online store. It is a simple and feasible procedure which patients can perform on themselves (or guardians on their wards) after minimal training. The resolution of the image is adequate for follow up through teleconsultation. It is also a good teaching tool as it enables the sharing of views.

The vertigo of Meniere's disease may be related to the destruction and repair of inner ear membrane structure caused by improper contraction or spasm of tympanic tensor muscle.

RESUMO

OBJECTIVE: The ai/m of this study was to compare the self-reported confidence of novices in using a smartphone-enabled video otoscope, a microscope and loupes for ear examination and external ear canal procedures. METHOD: Medical students (n = 29) undertook a pre-study questionnaire to ascertain their knowledge of techniques for otoscopy and aural microsuction. Participants underwent teaching on ear anatomy, examination and procedural techniques using a microscope, loupes and smartphone-enabled video otoscopes. Confidence and preference using each modality was rated using a Likert-like questionnaire. RESULTS: After teaching, all modalities demonstrated a significant increase in confidence in ear examination (p < 0.0001). Confidence in using the smartphone-enabled otoscope post-teaching was highest (p = 0.015). Overall, the smartphone-enabled video otoscope was the preferred method in all other parameters assessed including learning anatomy or pathology (51.72 per cent) and learning microsuction (65.51 per cent). CONCLUSION: Smartphone-enabled video otoscopes provide an alternative approach to ear examination and aural microsuction that can be undertaken outside of a traditional clinical setting and can be used by novices.

RESUMO

Objective:To investigate the healing rate of subtotal perforation of tympanic membrane repaired by cartilage island technique combined with palisade cartilage technique under otoscope. Methods:A retrospective analysis was performed on 189 patients with chronic suppurative otitis media who were admitted to the Department of Otolaryngology and Head and Neck Surgery of Hunan Provincial People's Hospital from January 2018 to January 2020. The patients were divided into twogroups, in group onethere were 100 patients treated by senior surgeon, which were divided into two subgroups, Group A (68 cases) were treated with cartilage island technique alone, and Group B (32 cases) were treated with cartilage island technique combined with palisade cartilage technique. In group two there were 89 patients treated by junior surgeons, which were divided into two subgroups. In group C, 50 cases were treated with cartilage island technique alone, and in group D, 39 cases were treated with cartilage island technique combined with palisade cartilage technique. Results:The healing rate of tympanic membrane in group 1 was 96.0% (96/100), and in group 2 was 87.6%(78/89).There was statistically significant in group 1 and group 2(χ²=4.504, P=0.034).The healing rate of tympanic membrane was 94.1% (64/68) in group A, 100%(32/32)in group B, 80.0%(40/50) in group C, and 97.4% (38/39) in group D. There was no statistically significant difference between group A and group B (χ²=1.961, P=0.161), there was statistically significant difference between group C and group D (χ²=6.149, P=0.013), and there was statistically significant difference between group A and group C(χ²=5.492, P=0.019)There was no statistical difference between group B and group D(χ²=0.832, P=0.362). Conclusion:For beginners of tympanoplasty, the use of cartilage island technique combined with palisade cartilage technique in otoscope can significantly improve the success rate of tympanoplasty with subtotal tympanic perforation.

RESUMO

PURPOSE: This study aimed to evaluate the outcomes and satisfaction of ear patients who participated in the smartphone otoscopes telemedicine via WeChat. METHODS: Patients in this study included newly diagnosed outpatients and online patients who did not undergo an outpatient diagnosis. Patients performed regular ear self-examinations, took pictures at home using their smartphone endoscopes, and submitted images to a WeChat community. Otolaryngologist gave timely online feedback. All of the following data were recorded: patients age and gender, disease duration, outpatient diagnosis, side, telemedicine duration, number of telemedicine visits, outcomes, satisfaction. RESULTS: A total of 74 patients were included in the study, including 39 males and 35 females, with an average age of 31.1 ± 13.7 years (range 4-55 years). Of these patients, 68 were outpatients, and 6 directly participated in telemedicine online. The patient's disease duration ranged from 1 day to 15 days, with an average of 4.0 ± 3.0 days. The mean duration was 8.1 days (range: 3-21 days) for telemedicine. The mean number of visits was 2.7 times (range: 2-6 times) for telemedicine. 68 (91.9%) of the 74 patients were cured, 6 (8.1%) were improved, and 0 (0%) were ineffective. Almost all patients were pleased with the telemedicine service, 71.9 0% were very satisfied (n = 62), 28.10% were very satisfied (n = 11), and 0% were dissatisfied (n = 0). CONCLUSIONS: Smartphone otoscopes telemedicine can decrease outpatient follow-up, reduce the risk of cross-infection, increase telemedicine accuracy, and improve patient satisfaction. It is worthy of clinical application in the COVID-19 era.

RESUMO

INTRODUCTION: A cohort of 12 000 children in the Philippines who had enrolled in a 2000-2004 (current ages 16 to 20 years) Phase 3 11-valent pneumococcal conjugate vaccine for the prevention of radiographically confirmed pneumonia are now being asked to participate in a separate study (expected completion date September 2021) to assess the cohort's current long-term audiometric and otologic status. This new study would allow assessments of the utility of the pneumococcal vaccine in conferring its protective effects on the long-term sequelae of otitis media (OM), if any. Lack of trained local healthcare providers in otolaryngology/audiology and testing equipment in Bohol, Philippines, necessitates the development of a distinct methodology that would lead to meaningful data analysis. METHODS AND ANALYSIS: Reliable data collection and transfer are achieved by a US otolaryngologist/audiologist team training local nurses on all procedures in a didactic and hands-on process. An assortment of portable otolaryngologic and audiologic equipment suitable for field testing has been acquired, including an operating otoscope (Welch-Allyn), a video-otoscope (JedMed), a tympanometer with distortion product otoacoustic emission measurements (Path Sentiero) and a screening audiometer (HearScreen). Data will then be uploaded to a Research Electronic Data Capture database in the USA.Tympanometric and audiologic data will be codified through separate conventional algorithms. A team of paediatric otolaryngology advanced practice providers (APPs) have been trained and validated in interpreting video otoscopy. The protocol for classification of diagnostic outcome variables based on video otoscopy and tympanometry has been developed and is being used by APPs to evaluate all otoscopy data. ETHICS AND DISSEMINATION: The study was approved by the Research Institute of Tropical Medicine, Alabang, Manila, Philippines, and the institutional review board and the Colorado Multiple Institutional Review Board of the University of Colorado School of Medicine, Aurora, Colorado, USA.Research results will be made available to children and their caregivers with abnormal audiologic outcomes, the funders and other researchers. TRIAL REGISTRATION NUMBER: ISRCTN 62323832; Post-results.

RESUMO

Importance: During the novel coronavirus disease 2019 pandemic, telehealth has become a vital component of health care delivery. For otolaryngology evaluations, examination of the ear and oropharynx is important but difficult to achieve remotely. Objective: To assess the feasibility of patient use of low-cost digital videoscopes and smartphones for examination of the ear and oropharynx. Design, Setting, and Participants: A prospective quality improvement study was conducted in an academic adult otolaryngology clinic including 23 patients who presented for an in-person appointment and owned a smartphone device. The study was conducted from July 1 to 15, 2020. Interventions: Participants were asked to capture pictures and videos of their ear canals and oropharynx with digital videoscopes and their smartphones under real-time guidance over a telehealth platform. They were then surveyed about their experience. Main Outcomes and Measures: The primary outcomes were ratings by health care clinicians and a blinded otolaryngologist reviewer of image acceptability. Secondary outcomes included participant time to image acquisition and willingness to purchase digital videoscopes for telehealth use. Results: Of the 23 participants included, 14 were women (61%); mean age was 50 years (range, 21 to 80 years). Of the images obtained using the digital otoscope ear examination, 95% were considered acceptable by the health care clinicians and 91% were considered acceptable by the blinded reviewer; 16 participants (70%) reported that the otoscope was easy to use. The mean time to acquire images for both ears was 114 seconds (95% CI, 84-145 seconds). Twenty-one participants (91%) were willing to pay for a digital otoscope for telehealth use. For the oropharyngeal examination, a greater proportion of smartphone video examinations were considered acceptable by clinicians (63% acceptability) and the blinded reviewer (55%) compared with the digital endoscope (clinicians, 40%; blinded reviewer, 14%). The mean time required for the oropharyngeal examination smartphone video capture was shorter at 35 seconds compared with both the digital endoscope (difference, -27 seconds; 95% CI, -7 to -47 seconds) and smartphone photo capture (difference, -53 seconds; 95% CI, -20 to -87 seconds). Conclusions and Relevance: Digital otoscopes and smartphones apparently can facilitate remote head and neck physical examination in telehealth. Digital otoscopes were useful for ear examinations, and smartphone videos appeared to be the most useful for oropharyngeal examinations. Further studies are required to determine specific diagnostic capabilities in various telehealth practice settings.
