Performance After Cochlear Reimplantation Using a Different Manufacturer.

OBJECTIVE: To better understand cochlear implant (CI) performance after reimplantation with a different device manufacturer. STUDY DESIGN: Multisite retrospective review. SETTING: Tertiary referral centers. PATIENTS: Patients older than 4 years who received a CI and subsequently underwent CI reimplantation with a different manufacturer over a 20-year period. INTERVENTION: Reimplantation. MAIN OUTCOME MEASURE: The primary outcome was difference in the best CNC score obtained with the primary CI, compared with the most recent CNC score obtained after reimplantation. RESULTS: Twenty-nine patients met the criteria at three centers. The best average CNC score achieved by adult patients after primary cochlear implantation was 46.2% (n = 16), measured an average of 14 months (range: 3-36 mo) postoperatively. When looking at the most recent CNC score of adult patients before undergoing reimplantation, the average CNC score dropped to 19.2% (n = 17). After reimplantation, the average 3- to 6-month CNC score was 48.3% (n = 12), with most recent average CNC score being 44.4% (n = 17) measured an average of 19 months (range: 3-46 mo) postoperatively. There was no statistically significant difference (p = 0.321; t11 = 0.48) identified in performance between the best CNC score achieved by adult patients after primary cochlear implantation, and the most recent score achieved after reimplantation (n = 12). Analysis of prerevision and postrevision speech performance was not possible in pediatric patients (<18 yr old) because of differences in tests administered. CONCLUSION: Patients undergoing reimplantation with a different manufacturer achieved CNC score performance comparable to their best performance with their original device.

Voices of the accelerated: key themes when considering implementation of an accelerated medical school program.

In this rapid communication, accelerated undergraduate medical education is examined using prior literature as well as experiences of those who have completed or are in the process of completing accelerated medical curricula. The Consortium of Accelerated Medical Pathway Programs (CAMPP) hosts an annual multi-institutional conference for all its members. During the meeting in July 2023, a virtual panel was convened from multiple constituent programs (N = 4) including medical students (N = 2), resident physicians (N = 4), and faculty (N = 2). Panel participants represented current learners or graduates from accelerated pathways of varying specialties (N = 5) to share firsthand experiences about acceleration to an audience representing over 25 medical schools. Five key themes were identified for accelerated students and trainees: Reduced debt as motivating factor to accelerate, Feeling prepared for residency, Ideal accelerated students are driven, Ability to form early professional relationships, and Less time for additional clinical experiences. Discourse from the CAMPP panel can inform current and developing accelerated programs at institutions looking to create or improve accelerated learning.

Characterizing Cochlear Implant Trans-Impedance Matrix Heatmaps in Patients With Abnormal Anatomy.

OBJECTIVE: To characterize transimpedance matrix (TIM) heatmap patterns in patients at risk of labyrinthine abnormality to better understand accuracy and possible TIM limitations. STUDY DESIGN: Retrospective review of TIM patterns, preoperative, and postoperative imaging. SETTING: Tertiary referral center. PATIENTS: Patients undergoing cochlear implantation with risk of labyrinthine abnormality. INTERVENTION: None. RESULTS: Seventy-seven patients were evaluated. Twenty-five percent (n = 19) of patients had a TIM pattern variant identified. These variants were separated into 10 novel categories. Overall, 9% (n = 6) of electrodes were malpositioned on intraoperative x-ray, of which 50% (n = 3) were underinserted, 17% (n = 1) were overinserted, 17% (n = 1) had a tip foldover, and 17% (n = 1) had a coiled electrode. The number of patients with a variant TIM pattern and normal x-ray was 18% (n = 14), and the number of patients with normal TIM pattern and malposition noted on x-ray was 3% (n = 2; both were electrode underinsertions that were recognized due to open circuits and surgical visualization).A newly defined skip heat pattern was identified in patients with IP2/Mondini malformation and interscalar septum width <0.5 mm at the cochlear pars ascendens of the basal turn. CONCLUSIONS: This study defines novel patterns for TIM heatmap characterization to facilitate collaborative and comparative research moving forward. In doing so, it highlights a new pattern termed skip heat, which corresponds with a deficient interscalar septum of the cochlea pars ascendens of the basal turn in patients with IP2 malformation. Overall, the data assist the surgeon in better understanding the implications and limitations of TIM patterns within groups of patients with risk of labyrinthine abnormalities.

Video Otoscopy as a Novel Teaching and Remote Otolaryngology Consultation Tool at an Academic Medical Center.

OBJECTIVE: Assess the use of video otoscopy (VO) as a tool for teaching Emergency Department (ED) residents and remote Otolaryngology consultation. STUDY DESIGN: Survey and retrospective chart review. SETTING: Tertiary care center. METHODS: Emergency Medicine resident physicians completed an otologic skill self-assessment and pathology followed by an interactive training on VO and postintervention assessment after 9 months of use. Outcomes compared change in pre- to posttraining scores. ED consultations using VO during this time period were reviewed to detect differences between the presumed diagnosis/treatment based only on phone consultation and VO image compared to the final diagnosis/treatment after in-person Otolaryngology consultation. RESULTS: Forty-six (63.1%) ED residents participated. Diagnostic accuracy improved by 20.7% overall. The most improved diagnoses were of a normal ear canal (+75%), tympanosclerosis (+58.4%), and ear canal foreign body (+57.1%); most challenging were external auditory canal cyst (-13.6%), hemotympanum (-11.3%), and cerumen (-1.9%). Cholesteatoma did not improve because all responses were incorrect; neither did tympanic membrane perforation because all were correct. Confidence in the otologic exam and anatomy also increased (P < .01). Thirteen consults used VO and 3 (23.1%) had a change in diagnosis/treatment after in-person Otolaryngology evaluation. CONCLUSION: Training on the use of VO significantly improves the confidence and diagnostic skills of ED providers for many pathologies. This application suggests the efficacy of an otologic e-consultation model.

Image Quality and Artifact Reduction of a Cochlear Implant With Rotatable Magnets.

OBJECTIVE: To determine if metal reduction magnetic resonance imaging sequences and changes in implant placement minimize artifact from cochlear implants and improve visualization of intracranial structures. STUDY DESIGN: Cadaveric study. SETTING: Tertiary referral center. PATIENTS: Five cadaveric heads. INTERVENTIONS: Specimens were implanted with Advanced Bionics HiRes Ultra3D devices at nasion-external auditory canal angles of 90, 120, and 160 degrees, and distances from the external auditory canal of 9 or 12 cm. Standard brain/internal auditory canal (IAC) sequences with metal artifact reducing technique were acquired in a 1.5T scanner. MAIN OUTCOME MEASURES: The primary outcome was visibility of 14 intracranial structures graded on a 4-point scale (1, structures <50% visible; 2, >50% visible with some areas nonvisible from artifact; 3, artifact present but adequate for diagnosis; and 4, high quality). Scores were determined by experienced head and neck radiologists and compared with one-way analysis of variance. RESULTS: Imaging sequences included axial 5-mm whole-brain turbo spin echo (TSE) T2 with right to left and anterior to posterior encoding, fluid-attenuation inversion recovery high bandwidth, axial 5-mm whole-brain slice-encoding metal artifact correction (SEMAC), axial IAC constructive interference in steady state, and axial 3-mm T1 IAC with and without fat saturation. T1 IACs in axial and coronal planes were best for ipsilateral structures overall (mean [standard deviation {SD}], 3.8 [0.6] and 3.8 [0.5]). SEMAC (mean [SD], 3.5 [0.8]) was superior to TSE with anterior to posterior encoding (mean [SD], 3.5 [0.9) for ipsilateral cortex, cerebellopontine angle, and brainstem/cerebellum, and equivalent for the inner ear. Constructive interference in steady state and T1 with fat saturation were poor for all ipsilateral structures (mean, 2.8 [ p < 0.01]; mean, 3.1 [ p < 0.01]). The 120 degrees/12 cm position was overall best, although the 120 degrees/9 cm position still afforded visualization of ipsilateral structures; other angles and distances conferred slight advantages for specific structures of interest. CONCLUSIONS: SEMAC and T2 TSE with anterior to posterior encoding sequences provide artifact suppression while retaining excellent image quality. Different placement angles did not confer improvement in visualization, although placement distances provided slight advantages for some structures.

HiRes ultra series cochlear implant field recall: failure rates and early outcomes.

OBJECTIVE: Evaluate rates of Advanced Bionics Ultra 3D/Ultra cochlear implant failure in the setting of a worldwide device recall and report surgical and auditory outcomes after revision. METHODS: Retrospective chart review was performed for adult and pediatric patients implanted with at risk devices at our center from 2016 to 2020. Device failure rates, surgical, and auditory outcomes were recorded and analyzed. RESULTS: Of 113 at-risk devices, 20 devices (17.7%) in 18 patients (two bilaterally implanted) were identified as failures. All devices were with mid-scala electrodes. Eleven patients (61.1%) were children and 7 (38.9%) adults. Twelve patients were found to have failing devices after reporting subjective performance decline; the remainder were prompted by manufacturer notification. All were revised, with the majority (83.3%) choosing the same manufacturer. All had uncomplicated original and revision insertions. Among adults, average word scores on the revised side were stable pre- to post-revision (P = 0.95). DISCUSSION: Patients with device failure due to this field action performed well after revision implantation. Patients with bilateral at-risk devices but evidence of unilateral failure may elect to undergo simultaneous empiric revision of the contralateral device. Three patients who elected to change device manufacturers on revision have variable results that require further investigation. CONCLUSIONS: Patients requiring revision for a device field action overall perform well. At-risk devices continue to require monitoring as a growing number are likely to fail over time.

Slim Modiolar Electrode Placement in Candidates for Electroacoustic Stimulation.

OBJECTIVES: To determine rates of hearing preservation and performance in patients who met candidacy for electroacoustic stimulation (EAS) and were implanted with a slim modiolar electrode (CI532 or CI632). DESIGN: Adult patients meeting Food and Drug Administration criteria for electroacoustic stimulation (preoperative low-frequency pure-tone average [LFPTA] less than 60 dB at 125, 250, and 500 Hz and monosyllabic word scores between 10% and 60% in the ear to be implanted), who received a slim modiolar electrode were included. Main outcome measures included rates of hearing preservation, defined as a LFPTA ≤80 dB at 125, 250, and 500 Hz, as well as postoperative low-frequency pure-tone threshold shifts, consonant-Nucleus-Consonant (CNC) word scores and AzBio sentences in noise scores. RESULTS: Forty-six patients met inclusion criteria during a 4-year period. Mean (standard deviation) preoperative LFPTA was 34.5 (13.0) dB, and 71.7% had preserved hearing at initial activation. The mean LFPTA shift in patients who preserved hearing at initial activation was 19.7 (14.6) dB, compared with 62.6 (17.7) dB in patients who did not preserve hearing as per our definition. Perioperative steroid use was not different in patients with and without preserved hearing (X 2 (1, N = 46) = 0.19, p = .67, V = 0.06). One year after surgery, 57% of patients had a decline in LFPTA >80 dB and were no longer considered candidates for EAS, with 34.7% still retaining low-frequency thresholds ≤80 dB. CNC word scores at 1 year were 69.9% and 61.4% among individuals with and without preserved low-frequency hearing respectively, measured in their CI ear alone, in their regular listening condition of EAS or electric only ( t (32) = 1.13, p = 0.27, d = 0.39, 95% CI = -6.51, 22.86). Device use time did not differ between groups. Among adults with preserved residual hearing at 1 year (n = 16), 44% used EAS, although there was no significant difference in performance between EAS users and nonusers with preserved hearing. Loss of residual hearing over time did not result in a decline in speech perception performance. CONCLUSION: The present study demonstrated favorable early rates of hearing preservation with a slim modiolar array. Performance was not significantly different in individuals with and without preserved low-frequency acoustic hearing, independent of EAS use. Compared with reports of short electrode use, the loss of residual hearing in patients implanted with this array did not impact speech perception performance.

Laryngeal Pathologies Associated with the Genre of Singing and Professional Singing Status in a Treatment-Seeking Population.

OBJECTIVES/HYPOTHESIS: Singers have high vocal demands and are at increased risk of developing voice disorders. Different singing genres place different technical demands on the voice. However, differences in laryngeal pathology based on genre have not been well-researched. The purpose of this study was to determine the prevalence of laryngeal pathology in different genres of professional and amateur singers who present with a voice complaint. STUDY DESIGN: Retrospective review. METHODS: Retrospective review of patients seen at a tertiary laryngology practice. Self-identified singers who reported their primary singing genre and categorized their singing as a full-time job, part-time job, or amateur involvement were included. Type and prevalence of pathology were calculated based on genre and professional status. RESULTS: Of the 302 self-identified singers, 54% (n = 164) had laryngeal pathology. Among those with pathology, the most common finding was fibrotic lesion (38.4%, 63/164). Genres in which a majority of singers had pathology were other (69.2%, 9/13), choral (64.7%, 11/17), pop (63.2%, 12/19), musical theater (61.4%, 43/70), country (100%, 4/4), and Latin (100%, 2/2). The highest prevalence of pathology was seen in part-time professional singers (62.2%, 41/66) and full-time professionals (60.8%, 62/102), compared to amateurs (45.1%, 60/133). CONCLUSIONS: Laryngeal pathology is prevalent in singers presenting with a voice complaint. Regardless of genre or professional status, fibrotic lesions were the most common pathological finding. This study provides preliminary data on the prevalence of different laryngeal pathologies found in singers by genre and degree of professional involvement. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:2076-2080, 2021.

Respiratory viruses in pediatric emergency department patients and their family members.

BACKGROUND: Respiratory viral infections account for a substantial fraction of pediatric emergency department (ED) visits. We examined the epidemiological patterns of seven common respiratory viruses in children presenting to EDs with influenza-like illness (ILI). Additionally, we examined the co-occurrence of viral infections in the accompanying adults and risk factors associated with the acquisition of these viruses. METHODS: Nasopharyngeal swab were collected from children seeking medical care for ILI and their accompanying adults (Total N = 1315). Study sites included New York Presbyterian, Bellevue, and Tisch hospitals in New York City. PCR using a respiratory viral panel was conducted, and data on symptoms and medical history were collected. RESULTS: Respiratory viruses were detected in 399 children (62.25%) and 118 (17.5%) accompanying adults. The most frequent pathogen detected was human rhinovirus (HRV) (28.81%). Co-infection rates were 14.79% in children and 8.47% in adults. Respiratory syncytial virus (RSV) and parainfluenza infections occurred more often in younger children. Influenza and HRV occurred more often in older children. Influenza and coronavirus were mostly isolated in winter and spring, RSV in fall and winter and HRV in fall and spring. Children with HRV were more likely to have history of asthma. Adults with the same virus as their child often accompanied ≤ 2-year-old-positive children and were more likely to be symptomatic compared to adults with different viruses. CONCLUSIONS: Respiratory viruses, while presenting the same suite of symptoms, possess distinct seasonal cycles and affect individuals differently based on a number of identifiable factors, including age and history of asthma.
