Barriers and Facilitators of Vestibular Rehabilitation: Patients and Physiotherapists' Perspectives.

BACKGROUND AND PURPOSE: Poor adherence to vestibular rehabilitation protocols is a known barrier to optimal care. Vestibular clinicians' comprehensive understanding of the barriers and facilitators to vestibular home exercise programs (VHEP) is a key element to achieving optimal care in the context of vestibular rehabilitation. The aims of this study are as follows: (1) to identify primary barriers and facilitators to VHEP from the perspective of patients with vestibular dysfunction and vestibular physical therapists (PTs); and (2) to provide strategies for clinicians to improve adherence and outcomes of VHEP. METHODS: A qualitative research with single-session focus groups conducted separately for: (1) patients with vestibular disorders and (2) vestibular PTs. Six focus groups were conducted, 3 for each population, with a total of 39 participants. An online survey was conducted to evaluate the estimates of adherence rates, followed by a structured discussion over barriers and facilitators to VHEP as perceived by patients and PTs. Thematic data analyses were performed using a mixed deductive-inductive approach. RESULTS: Eighteen patients with vestibular disorders and 21 experienced vestibular PTs participated in this study. Six barrier categories and 5 facilitator categories were identified. Barriers included motivation aspects, provocation of symptoms, time management, associated impairments, missing guidance and feedback, and psychosocial factors. Facilitators included motivation aspects, time management, patient education and exercise instructions, exercise setting, and associated symptom management. DISCUSSION AND CONCLUSIONS: Clinicians who prescribe home exercise to patients with vestibular disorders can use this information about common barriers and facilitators for patient education and to provide optimal care and improve rehabilitation outcomes.

ChatGPT's adherence to otolaryngology clinical practice guidelines.

OBJECTIVES: Large language models, including ChatGPT, has the potential to transform the way we approach medical knowledge, yet accuracy in clinical topics is critical. Here we assessed ChatGPT's performance in adhering to the American Academy of Otolaryngology-Head and Neck Surgery guidelines. METHODS: We presented ChatGPT with 24 clinical otolaryngology questions based on the guidelines of the American Academy of Otolaryngology. This was done three times (N = 72) to test the model's consistency. Two otolaryngologists evaluated the responses for accuracy and relevance to the guidelines. Cohen's Kappa was used to measure evaluator agreement, and Cronbach's alpha assessed the consistency of ChatGPT's responses. RESULTS: The study revealed mixed results; 59.7% (43/72) of ChatGPT's responses were highly accurate, while only 2.8% (2/72) directly contradicted the guidelines. The model showed 100% accuracy in Head and Neck, but lower accuracy in Rhinology and Otology/Neurotology (66%), Laryngology (50%), and Pediatrics (8%). The model's responses were consistent in 17/24 (70.8%), with a Cronbach's alpha value of 0.87, indicating a reasonable consistency across tests. CONCLUSIONS: Using a guideline-based set of structured questions, ChatGPT demonstrates consistency but variable accuracy in otolaryngology. Its lower performance in some areas, especially Pediatrics, suggests that further rigorous evaluation is needed before considering real-world clinical use.

Advancing Medical Practice with Artificial Intelligence: ChatGPT in Healthcare.

BACKGROUND: Advancements in artificial intelligence (AI) and natural language processing (NLP) have led to the development of language models such as ChatGPT. These models have the potential to transform healthcare and medical research. However, understanding their applications and limitations is essential. OBJECTIVES: To present a view of ChatGPT research and to critically assess ChatGPT's role in medical writing and clinical environments. METHODS: We performed a literature review via the PubMed search engine from 20 November 2022, to 23 April 2023. The search terms included ChatGPT, OpenAI, and large language models. We included studies that focused on ChatGPT, explored its use or implications in medicine, and were original research articles. The selected studies were analyzed considering study design, NLP tasks, main findings, and limitations. RESULTS: Our study included 27 articles that examined ChatGPT's performance in various tasks and medical fields. These studies covered knowledge assessment, writing, and analysis tasks. While ChatGPT was found to be useful in tasks such as generating research ideas, aiding clinical reasoning, and streamlining workflows, limitations were also identified. These limitations included inaccuracies, inconsistencies, fictitious information, and limited knowledge, highlighting the need for further improvements. CONCLUSIONS: The review underscores ChatGPT's potential in various medical applications. Yet, it also points to limitations that require careful human oversight and responsible use to improve patient care, education, and decision-making.

A Five-Decade Text Mining Analysis of Cochlear Implant Research: Where We Started and Where We Are Heading.

Background and Objectives: Since its invention in the 1970s, the cochlear implant (CI) has been substantially developed. We aimed to assess the trends in the published literature to characterize CI. Materials and Methods: We queried PubMed for all CI-related entries published during 1970-2022. The following data were extracted: year of publication, publishing journal, title, keywords, and abstract text. Search terms belonged to the patient's age group, etiology for hearing loss, indications for CI, and surgical methodological advancement. Annual trends of publications were plotted. The slopes of publication trends were calculated by fitting regression lines to the yearly number of publications. Results: Overall, 19,428 CIs articles were identified. Pediatric-related CI was the most dominant sub-population among the age groups, with the highest rate and slope during the years (slope 5.2 ± 0.3, p < 0.001), while elderly-related CIs had significantly fewer publications. Entries concerning hearing preservation showed the sharpest rise among the methods, from no entries in 1980 to 46 entries in 2021 (slope 1.7 ± 0.2, p < 0.001). Entries concerning robotic surgery emerged in 2000, with a sharp increase in recent years (slope 0.5 ± 0.1, p < 0.001). Drug-eluting electrodes and CI under local-anesthesia have been reported only in the past five years, with a gradual rise. Conclusions: Publications regarding CI among pediatrics outnumbered all other indications, supporting the rising, pivotal role of CI in the rehabilitation of children with sensorineural hearing loss. Hearing-preservation publications have recently rapidly risen, identified as the primary trend of the current era, followed by a sharp rise of robotic surgery that is evolving and could define the next revolution.

[SLEEP HABIT MODIFICATION AS A POSSIBLE PREVENTION OF RECURRENT BENIGN PAROXYSMAL POSITIONAL VERTIGO].

BACKGROUND: Benign paroxysmal positional vertigo (BPPV) is effectively treated with a variety of repositioning maneuvers but one-third to one-half of patients experience recurrence, usually within 2 years after the first attack. OBJECTIVES: The aim of this study was to investigate possible prevention of recurrent BPPV by sleep habit modification. METHODS: Patients diagnosed with posterior semicircular canal BPPV (p-BPPV) were asked their preferred lying side during nocturnal sleep. Following Epley maneuver they were recommended to change their head lying side at least every 2 hours during nocturnal sleep and to come back in case of recurrence. RESULTS: A total of 266 patients were diagnosed with p-BPPV. The mean patient's age was 57 years (range 14-87 years). There were 167 patients with right p-BPPV and 99 patients with left p-BPPV; 134 (50%) patients habitually slept on the right side. Of those, 112 (84%) were diagnosed with right p-BPPV (P= 0.0006); 87 patients (33%) habitually slept on the left side; 56 of them (64%) were diagnosed with left p-BPPV (P <0.0001). Among the 45 patients (17%) who expressed no preference concerning their sleeping positions, the right versus left p-BPPV was nearly even. During the follow-up period (1-80 months, mean 41) 11 patients (4%) were diagnosed with recurrent p-BPPV. Of those, 9 had a recurrence in the same posterior semicircular canal and 2 in the contralateral one. All of them reported that they had not modified their sleep habits. CONCLUSIONS: The results of our study can shed some light on the etiology of BPPV and may be helpful in preventing recurrent BPPV by changing sleep-position habits.

Navigating the vestibular maze: text-mining analysis of publication trends over five decades.

Introduction: The field of vestibular science, encompassing the study of the vestibular system and associated disorders, has experienced notable growth and evolving trends over the past five decades. Here, we explore the changing landscape in vestibular science, focusing on epidemiology, peripheral pathologies, diagnosis methods, treatment, and technological advancements. Methods: Publication data was obtained from the US National Center for Biotechnology Information (NCBI) PubMed database. The analysis included epidemiological, etiological, diagnostic, and treatment-focused studies on peripheral vestibular disorders, with a particular emphasis on changes in topics and trends of publications over time. Results: Our dataset of 39,238 publications revealed a rising trend in research across all age groups. Etiologically, benign paroxysmal positional vertigo (BPPV) and Meniere's disease were the most researched conditions, but the prevalence of studies on vestibular migraine showed a marked increase in recent years. Electronystagmography (ENG)/ Videonystagmography (VNG) and Vestibular Evoked Myogenic Potential (VEMP) were the most commonly discussed diagnostic tools, while physiotherapy stood out as the primary treatment modality. Conclusion: Our study presents a unique opportunity and point of view, exploring the evolving landscape of vestibular science publications over the past five decades. The analysis underscored the dynamic nature of the field, highlighting shifts in focus and emerging publication trends in diagnosis and treatment over time.

Revision Cochlear Implantation With Device Manufacturer Conversion: Surgical Outcomes and Speech Perception Performance.

OBJECTIVE: Describe the clinical profile of revision cochlear implantation (RCI) cases involving device manufacturer conversion (RCImc+), compare them to cases without manufacturer conversion (RCImc-), and classify the reasons for manufacturer conversion (MC). STUDY DESIGN: Retrospective case review. SETTING: Tertiary academic center. METHODS: Data on demographics, RCI indications, medical background, surgical details, and the reasons for MC were collected for all RCIs from 1989 to 2020. Post-RCI speech perception performance was categorized as unchanged, improved, or declined, according to clinically based criteria. RESULTS: Of 185 RCIs, 39 (21%) involved MC, mostly in pediatric patients (67%). The leading RCImc+ indications were device-related (59%) and medical (31%) failures. Initial implant manufacturers were Advanced Bionics (49%), Cochlear (25.5%), or Medel (25.5%). Most MC reasons were patient-driven (64%) versus CI team recommendations (36%). The RCImc+ group demonstrated a 3-fold higher rate of medical indications than RCImc- (31% vs 11.5%, P = .007). The time interval from symptom onset to RCI was longer in RCImc+ (43 vs 20.3 months, P = .001), and the rate of multiple revisions in the same ear was higher (25.6% vs 8.2%, P = .009). Complete reinsertion rates were high in both RCImc+ and RCImc- (94.8% vs 94.5%, P = 1) without any complications. Speech perception improved or remained unchanged in most (84%) cases, with no significant difference between the groups (P = .183). CONCLUSION: This retrospective study showed that RCI involving MC is safe and beneficial. Although RCImc+ patients exhibited distinct clinical characteristics, MC did not impact surgical or speech perception outcomes. This provides evidence-based data to support informed decision-making by CI teams and patients.

The Prevalence of Hearing Impairments in Women with Silicone Breast Implants.

Many women with silicone breast implants (SBIs) report non-specific complaints, including hearing impairments. Hearing impairment appears to be associated with a number of autoimmune conditions. The current study aimed to evaluate the prevalence and severity of hearing impairments among women with SBIs and to explore potential improvements in their hearing capability following implant removal. Symptomatic women with SBIs (n = 160) underwent an initial anamnestic interview, and women who reported hearing impairments were selected for the study. These women completed self-report telephone questionnaires regarding their hearing difficulties. Some of these women underwent subjective and objective hearing tests. Out of 159 (50.3%) symptomatic women with SBIs, 80 reported hearing impairments, including hearing loss (44/80; 55%) and tinnitus (45/80; 56.2%). Five out of seven (71.4%) women who underwent an audiologic evaluation exhibited hearing loss. Of women who underwent silicone implant removal, 27 out of 47 (57.4%) reported the improvement or resolution of their hearing complaints. In conclusion, hearing impairment is a frequent complaint among symptomatic women with SBIs, and tinnitus was found to be the most common complaint. A significant reduction in hearing difficulties was observed following silicone implant removal. Further studies using larger populations are needed to verify the occurrence of hearing impairments in these women.

[Compliance with diagnostic MRI in the workup of sudden sensorineural hearing loss].

INTRODUCTION: Sudden sensorineural hearing loss (SSNHL] can be the presenting symptom of an acoustic neurinoma. High sensitivity and specificity rates define magnetic resonance imaging (MRI) of the brain and internal acoustic canal as the gold standard for the diagnosis of retro-cochlear pathologies. A previous study revealed low compliance rates (49%] for performing an MRI after an episode of SSNHL; 15% of patients who had an MRI were diagnosed with a retro-cochlear pathology. AIM OF STUDY: To evaluate current compliance rates for performing an MRI of the brain and internal acoustic canal after an episode of SSNHL. MATERIAL AND METHODS: The study cohort included 41 patients, 24 females and 17 male, with an average age of 49.8 +/- 16.8 years (range, 16-78 years), who were diagnosed with SSNHL and admitted for treatment between December 2009 and June 2010. RESULTS: Two months after discharge from hospitalization, only 29 patients (70.7%) returned for the scheduled followup. Only 21 patients (51.2% of those admitted) had an MRI of the brain and internal acoustic canal, as was recommended upon their discharge. Three of those who had an MRI were diagnosed with a retro-cochlear pathology. In 20 patients [48.8%) who did not perform an MRI, a retro-cochlear pathology could not be ruled out. CONCLUSIONS: Compliance rates for performing an MRI after an episode of SSNHL haven't changed in recent years. The main reason seems to be poor patients' compliance, as well as their general practitioners and health insurance companies. Ruling out retro-cochlear pathologies by means of MRI is highly important and considered common medical practice. Guidelines regarding the importance of MRI after an episode of SSNHL should be updated and reinforced.

The Epidemiological and Financial Effects of Pneumococcal Vaccination on Otitis Media Related Admissions in the United States.

OBJECTIVE: To quantify the prevalence of hospital admissions, the financial impact, and the trends in surgical procedure rates for AOM and CAOM for all ages before and after 13-valent pneumococcal conjugate vaccine (PCV13) introduction. METHODS: Retrospective analysis of the National Inpatient Sample (NIS) from 1998 to 2013 to determine the prevalence of AOM/CAOM related admissions and weighted frequencies of AOM/CAOM related International Classification of Diseases, ninth revision (ICD-9) hospital diagnoses. Prevalence of surgical procedures to treat CAOM, cost of admission, length of stay, and cost per day of admission were tabulated. Trend analysis of this data was performed. RESULTS: A total of 46 580 patients were hospitalized with AOM in the designated time period, of which 37 366 had CAOM. The prevalence of hospital admission due to AOM had the most pronounced decrease from pre-vaccine era (1998) to post-PCV13 implementation (2013) in age group 0 to 4 (32%) followed by age group 5 to 19 (7%). Age groups 20-64 and 65+ showed slight increases in prevalence. The trend in prevalence of admissions due to CAOM mirrors that of overall admissions with an 18% and 5.8% decrease in age groups 0-4 and 5-19, respectively, and a 1% increase in ages 20+. The inflation adjusted mean cost of admission did not significantly increase between 2001 and 2013. The total cost per admission was $4428 and $7546 for those with AOM and CAOM, respectively. Mastoidectomy rates increased by 17% in hospitalized children during the post-vaccine era but decreased in the elderly population. CONCLUSION: The prevalence of AOM/CAOM hospital admissions decreased from the pre-vaccine era (1998) to post-PCV13 implementation (2013) in pediatric patients. Surgical procedure utilization and cost of hospital admission for AOM/CAOM did not increase throughout the study period.

The pattern of hearing outcome following surgery of the semicircular canals.

OBJECTIVE: To analyze demographic, clinical, surgical, and audiometric factors that may affect hearing outcome following surgery for the semicircular canals (SCC). METHOD: This is a retrospective case review of adults who underwent surgeries for superior SCC (SSCC), lateral SCC (LSCC), or posterior SCC (PSCC) and whose data were extracted and analyzed for factors affecting the hearing outcome in these procedures. RESULTS: Thirteen patients underwent surgery for SSCC, seven cases for the LSCC, one for the PSCC, and one case of combined PSCC/SSCC surgery. The mean age was 49.8 ± 12 years (21-66). There was no difference between the preoperative and postoperative pure tone average (PTA) thresholds at 0.5-3 kHz. Higher thresholds were noted at 4, 6, and 8 kHz postoperatively. Deterioration (>10 dB) in the bone-conduction (BC) PTA was demonstrated in 3 of 22 (13.6%) cases with no significant difference in the demographic, clinical, surgical, and preoperative audiometric parameters relative to the cases without PTA BC change. A significantly larger difference in PTA BC (pre- vs. postoperative) was seen for males. Small effect size was noted for Air conduction (AC) PTA in males, and moderate effect size for Word Recognition Score (WRS) in surgery for the LSCC compare to SSCC. CONCLUSIONS: SCC surgeries carry a relatively low risk of deterioration in PTA BC. High frequency thresholds should also be included in postoperative hearing outcome assessment. Cases of LSCC for intractable Meniere's disease and surgery in males carry higher risk of poor postoperative hearing outcomes. Level of Evidence: 4.

Otoprotection to Implanted Cochlea Exposed to Noise Trauma With Dexamethasone Eluting Electrode.

Cochlear implantation (CI) is now widely used to provide auditory rehabilitation to individuals having severe to profound sensorineural hearing loss (SNHL). However, CI can lead to electrode insertion trauma (EIT) that can cause damage to sensory cells in the inner ear resulting in loss of residual hearing. Even with soft surgical techniques where there is minimal macroscopic damage, we can still observe the generation of molecular events that may initiate programmed cell death via various mechanisms such as oxidative stress, the release of pro-inflammatory cytokines, and activation of the caspase pathway. In addition, individuals with CI may be exposed to noise trauma (NT) due to occupation and leisure activities that may affect their hearing ability. Recently, there has been an increased interest in the auditory community to determine the efficacy of drug-eluting electrodes for the protection of residual hearing. The objective of this study is to determine the effect of NT on implanted cochlea as well as the otoprotective efficacy of dexamethasone eluting electrode to implanted cochlea exposed to NT in a guinea pig model of CI. Animals were divided into five groups: EIT with dexamethasone eluting electrode exposed to NT; EIT exposed to NT; NT only; EIT only and naïve animals (control group). The hearing thresholds were determined by auditory brainstem recordings (ABRs). The cochlea was harvested and analyzed for transcript levels of inflammation, apoptosis and fibrosis genes. We observed that threshold shifts were significantly higher in EIT, NT or EIT + NT groups compared to naive animals at all the tested frequencies. The dexamethasone eluting electrode led to a significant decrease in hearing threshold shifts in implanted animals exposed to NT. Proapoptotic tumor necrosis factor-α [TNF-α, TNF-α receptor 1a (TNFαR1a)] and pro-fibrotic transforming growth factor ß1 (TGFß) genes were more than two-fold up-regulated following EIT and EIT + NT compared to the control group. The use of dexamethasone releasing electrode significantly decreased the transcript levels of pro-apoptotic and pro-fibrotic genes. The dexamethasone releasing electrode has shown promising results for hearing protection in implanted animals exposed to NT. The results of this study suggest that dexamethasone releasing electrode holds great potential in developing effective treatment modalities for NT in the implanted cochlea.

Impact of Imaging in Management of Otosclerosis.

The use of imaging in otosclerosis for diagnosis, preoperative assessment, and follow-up has the potential to give the clinician an additional tier of patient evaluation and validation of diagnosis. Before stapes surgery, imaging may help avoid unnecessary middle ear explorations in nonotosclerotic cases, prevent potential complications, and assist in appropriate patient counseling regarding management expectations. Postoperatively, following unsuccessful air-bone gap closure in stapes surgery or conductive hearing deterioration following initial successful closure of the air bone gap, imaging can be used to determine the prosthesis position in the middle ear.

The Feasibility of Retrofacial Approach for Cochlear Implantation.

HYPOTHESIS: The retrofacial approach is a feasible approach to the round window niche and that the Round window-Sigmoid sinus line will help determine the feasibility of retrofacial approach for cochlear implantation unless there is a very high jugular bulb. BACKGROUND: When the round window cannot be visualized by facial recess approach during cochlear implantation, other conservative techniques can be used to improve visualization such as the retrofacial approach. METHODS: Thirteen adult dry cadaveric temporal bones were studied. Computed tomography (CT) scan was obtained on all temporal bones. An imaginary Round window-Sigmoid sinus line was drawn on the axial images. We assessed whether this line is anterior (including intersection) or posterior to the facial nerve (FN). The following closest distances were measured on CT scans: 1) posterior semicircular canal (PSC)-FN, 2) PSC-Stapedius muscle, 3) PSC-Jugular bulb, 4) lateral semicircular canal (LSC)-Jugular bulb, 5) sigmoid sinus-FN. A canal wall-up mastoidectomy, facial recess, and retrofacial approach were performed in all specimens. We have noted whether we need a standard or an extended mastoidectomy. RESULTS: The Round window-Sigmoid sinus line was posterior to the FN in all specimens. The retrofacial approach was feasible and the round window was visualized in all specimens. Extended mastoidectomy was required in seven specimens and the PSC-FN was ≤ 3 mm in five of them. CONCLUSION: Retrofacial approach is feasible in cochlear implantation when the Round window-Sigmoid sinus line is posterior to the FN and the jugular bulb is not obstructing the round window.

Prognostic factors for facial nerve palsy in a pediatric population: A retrospective study and review.

OBJECTIVES/HYPOTHESIS: To identify and analyze factors influencing the outcome of facial nerve palsy (FNP) in a pediatric population. STUDY DESIGN: Retrospective study. METHODS: Sixty-seven pediatric patients (72 consecutive cases) diagnosed with and treated for FNP were divided into two severity subgroups. Associations between recovery in these groups and categorical variables were assessed using the Fisher exact test and for age using the t test. RESULTS: Mean age on admission was 12.0 ± 4.5 years. Neither FNP outcome (graded by severity) nor improvement rates (expressed as the percentage of patients achieving a higher FNP grade over time) were influenced by gender, affected side, presence of polyneuropathy, etiology, or recurrent or familial FNP. In cases with comparable final outcome, improvement rates of those diagnosed with severe FNP on presentation (38.9% of cases) were significantly higher than mild-to-moderate FNP. Of the 47 patients who attended a follow-up examination 2 months after discharge, 70.2% have already recovered (by at least one House-Brackmann [H-B] grade) by the time they were discharged, whereas 90.9% achieved H-B grade ≤2, and 72.3% fully recovered (H-B grade 1) 2 months postdischarge. Adding antiviral medication did not affect FNP improvement rates or outcomes. CONCLUSIONS: Rates of infectious and traumatic etiology in our patients were higher than reported for adults, but the most common etiology-as in those adults-was idiopathic. Routine extended diagnostic workup was not helpful, and antiviral medications were ineffective. The prognosis of FNP in pediatric patients is excellent, with 90% recovery by 2 months after initial presentation. LEVEL OF EVIDENCE: 4 Laryngoscope, 127:1175-1180, 2017.

Cochlear implantation in a patient with Paget's disease.

Hearing loss in Paget's disease, a metabolic bone disease, has been reported in as many as 60% of cases, and is presumably related to changes in mineral density of the otic capsule. We describe a 59-year-old man with Paget's disease who had severe to profound hearing loss and was referred to us for cochlear implantation. Preoperative evaluation revealed poor communication skills despite significant residual hearing, raising concerns about postimplantation outcome. Nevertheless, implantation was successful. As our literature search yielded only one report of cochlear implantation in Paget's disease, we record our clinical experience and discuss the hearing rehabilitation dilemmas in this case.
