AbstractObjectiveTo report the first steps of a project to automate and optimize scheduling of multidisciplinary consultations for patients with longstanding dizziness utilizing artificial intelligence.Study DesignRetrospective case review.SettingQuaternary referral center.MethodsA previsit self‐report questionnaire was developed to query patients about their complaints of longstanding dizziness. We convened an expert panel of clinicians to review diagnostic outcomes for 98 patients and used a consensus approach to retrospectively determine what would have been the ideal appointments based on the patient's final diagnoses. These results were then compared retrospectively to the actual patient schedules. From these data, a machine learning algorithm was trained and validated to automate the triage process.ResultsCompared with the ideal itineraries determined retrospectively with our expert panel, visits scheduled by the triage clinicians showed a mean concordance of 70%, and our machine learning algorithm triage showed a mean concordance of 79%.ConclusionManual triage by clinicians for dizzy patients is a time‐consuming and costly process. The formulated first‐generation automated triage algorithm achieved similar results to clinicians when triaging dizzy patients using data obtained directly from an online previsit questionnaire.

AbstractNasal reconstruction presents the facial plastic surgeon with a complex problem given its functional and aesthetic importance. The dorsal nasal flap is a composite rotational flap of the glabella and nasal dorsum that can be used for nasal dorsum and tip defects of medium to large sizes. Given its composite nature, this flap can be split into its constituent parts—the epidermis and dermis and the subcutaneous tissue and superficial musculoaponeurotic system—without flap loss. This case series describes this technique and various potential applications within nasal reconstruction.

Abstract Alpha-gal syndrome (AGS) is an immunoglobulin E–mediated hypersensitivity to galatcose-alpha-1,3-galactose (alpha-gal), a carbohydrate compound present in nonprimate mammalian products. Initial exposure to alpha-gal most often occurs through a tick bite, most commonly the lone star tick in the United States. Repeated exposure to alpha-gal may elicit severe allergic reactions, including anaphylaxis. The allergy restricts dietary intake and may significantly impact perioperative risk, as many medications, anesthetics, and intraoperative surgical products utilize bovine or porcine-derived agents, including those containing magnesium stearate, glycerol, and gelatin. Here, we review the perineurosurgical care of two individuals with AGS and highlight pertinent clinical practices and perioperative management of these patients.

Abstract Objective To describe the experience and results from coordinated and closely scheduled radiosurgery and cochlear implantation (CI) in a vestibular schwannoma (VS) cohort. Patients Patients with VS who underwent radiosurgery followed by CI on the same or next day. Interventions Interventions included sequential radiosurgery and CI. Main Outcome Measures Tumor control defined by tumor growth on posttreatment surveillance and audiometric outcomes including consonant-nucleus-consonant words and AzBio sentences in quiet. Results In total, six patients were identified that met the inclusion criteria, with an age range of 38 to 69 years and tumor sizes ranging from 2.0 to 16.3 mm. All patients successfully underwent radiosurgery and CI on the same or immediately successive day. Postoperatively, all patients obtained open-set speech recognition. Consonant-nucleus-consonant word scores ranged from 40 to 88% correct, and AzBio scores ranged from 44 to 94% correct. During posttreatment magnetic resonance imaging surveillance, which ranged from 12 to 68 months, all tumors were noted to be adequately visualized, and no tumor progression was noted. Conclusion Coordinated radiosurgery and CI can be safely performed in patients with VS on the same or next day, serving to decrease burden on patients and increase access to this vital rehabilitative strategy.

AbstractObjectivesSingle‐use rhinolaryngoscopes were brought to market in 2019 as an alternative to traditional reusable scopes and have garnered interest across settings given portability and potential cost advantages. While single‐use was previously evaluated compared to traditional devices, the overall impact to the consult experience for both users and patients has not been captured.MethodsEighteen residents performed consults with both single‐use and reusable rhinolaryngoscope systems on alternating weeks. A five‐question cumulative survey administered across three assessment points over a 12‐week period using a five‐point rating system to rate favorability. Residents and patients also completed four‐point scale surveys following procedure(s) to capture the consult experience. Statistical analyses were performed to measure significance differences between survey responses between the two systems.ResultsSingle‐use rhinolaryngoscopes received higher overall ratings compared with reusables across each metric captured including overall consult time (4.3 vs. 2.2, p < .001), multiscope consults (4.4 vs. 3.1, p < .001), patient communication (4.6 vs. 2.1, p < .001), teaching opportunities (4.6 vs. 2.1, p < .001), and overall ease of use (4.7 vs. 2.6, p < .001). Residents rated single‐use higher than reusable after each procedure in terms of ease of use (1.07 vs. 2.68, p < .001) and visual clarity (1.27 vs. 1.89, p = .003), while patients rated single‐use higher for understanding of illness (3.9 vs. 3.1, p < .001) and understanding of treatment rationale (3.9 vs. 3.1, p < .001).ConclusionResident and patient experience feedback favored single‐use rhinolaryngoscopes compared to reusable scope technology across multiple surveyed measurables. Single‐use rhinolaryngoscopes provide a viable tool for otorhinolaryngologist and other clinicians to perform rhinolaryngoscopy consults.Level of Evidence4.

This study described the outcomes of patients receiving topical, nebulized, endobronchial, or systemic tranexamic acid (TXA) for bleeding events while on extracorporeal membrane oxygenation (ECMO). We performed a single-center case series including adult patients >18 years old supported on either venovenous (VV) or venoarterial (VA) ECMO from January 1, 2014, to April 21, 2021. The primary outcome was hemostatic control defined as a composite of initial cessation of therapeutic interventions to mitigate bleeding or resumption of anticoagulation if previously held. Secondary outcomes included changes in transfusion requirements and lysis at 30-minute (LY30) values, venous thromboembolism (VTE) events, and seizures. In total, 47 patients were included for full analysis. There were 19 patients with surgical bleeds, 18 patients with medical bleeds, and 10 patients with multiple bleeds. Overall, initial hemostatic control was achieved in 79%, 67%, and 90% of patients, respectively. Pre- and post-TXA transfusion requirements were not significantly different (p = 0.2), although the intraindividual change in median LY30 was −5.1% compared with baseline (95% confidence interval [CI], −12.4% to −1.5%, p = 0.005). The occurrence of VTE and seizures was relatively low and similar among patient bleeding groups. Tranexamic acid provided initial hemostatic control in roughly three quarters of patients with bleeding events on ECMO and side effects were infrequent.

Objective To describe the development, implementation, and validation of a radiology-administered protocol to obtain magnetic resonance imaging (MRI) in patients with cochlear implants and auditory brainstem implants without magnet removal. Study Design Retrospective review and description of novel care pathway. Methods A radiology-administered protocol was designed based on careful input from the radiology safety committee and neurotology. Radiology technologist training modules, consent instructions, patient educational material, clinical audits, and other safeguards were implemented, with samples provided in this report. The primary outcomes measured included instances of magnet displacement during MRI and premature termination of MRI studies secondary to pain. Results Between June 19, 2018, and October 12, 2021, 301 implanted ears underwent MRI without magnet removal, including 153 devices housing diametric MRI-conditional magnets, and 148 implants with conventional axial (i.e., nondiametric) magnets. Among cases with diametric MRI-conditional magnets, all studies were completed without magnet dislodgement or need to terminate imaging early due to pain. Among cases with conventional axial (nondiametric) magnets, 29 (19.6%) MRI studies were stopped prematurely secondary to pain or discomfort; the overall rate of this event was 9.6% (29 of 301) among the entire study cohort. In addition, 6.1% (9 of 148) experienced confirmed magnet displacement despite headwrap placement; the overall rate among all cases was 3.0% (9 of 301). Eight of these patients received successful external magnet reseating through manual pressure on the external scalp without surgery, and one required surgical replacement of the magnet in the operating room. There were no documented instances of hematoma, infection, device or magnet extrusion, internal device movement (i.e., gross receiver-stimulator migration), or device malfunction in this cohort related to MRI. Conclusions We present the successful implementation of a radiology-administered protocol designed to streamline care for cochlear implant and auditory brainstem implant recipients who require MRI and ease clinical demands for otolaryngology providers. Examples of resources developed, including a process map, radiology training modules, consent instructions, patient educational materials, clinical audit, and other procedural safety measures are provided so interested groups may consider adapting and implementing related measures according to need.

Abstract Objective To evaluate the safety and outcomes of cochlear implantation (CI) in patients with ventriculoperitoneal (VP) shunts to inform clinical practice. Study Design Historical cohort study. Setting Tertiary referral centers. Methods A multi‐institutional historical cohort of patients with VP shunts and CI was identified and analyzed. Results A total of 46 patients (median age 8 years [interquratile range, IQR: 2‐46]) with VP shunts and CI were identified. Of these, 41 (89%) patients had a VP shunt prior to CI. Based on institutional preference and individual patient factors, CI was performed contralateral to a pre‐existing VP shunt in 24 of these 41 cases (59%) and ipsilateral in 17 (41%). Furthermore, pre‐CI relocation of the VP shunt was performed in 3 cases (7%), and 2 patients (5%) underwent planned revision of their VP shunt concurrent with CI. In total, 2 of 27 pediatric patients (7%) required unanticipated revision shunt surgery, both contralateral to CI device placement, given VP shunt malfunction. One of 19 adult patients (5%) required shunt revision during CI due to shunt damage noted intraoperatively. Among 43 patients with available follow‐up, 38 (88%) are regular CI users, with a median consonant‐nucleus vowel‐consonant word: score of 58% (IQR: 28‐72). Conclusion CI can be performed at low risk, either contralateral or ipsilateral, to a VP shunt, and does not mandate shunt revision in most cases. Additional considerations regarding CI receiver‐stimulator placement are necessary with programmable shunts to mitigate device interaction. Preoperative planning, including coordination of care with neurosurgery, is important to achieving optimal outcomes.

ABSTRACT Background There are few reports of dexterity tests being done in a distance telecommunication setting for residency applicant evaluation. Objective To report the feasibility and suitability of a virtual suturing skills assessment during residency interviews when added to the standard assessment process. Methods A suturing simulation was developed and implemented during otolaryngology–head and neck surgery (OHNS) residency interviews for the 2020-2021 cycle at one program. On the day of the interview, the activity was completed in real time using 2-camera video conferencing with the 2 resident assessors providing a numerical assessment based on an adapted scoring rubric from prior suturing activities at the institution. The exercise involved suturing a 3/4-inch Penrose drain circumferentially with half-vertical mattress stitches to simulate the maturation of a tracheostoma. The residency selection committee then completed a 7-item Likert-type survey, developed by the authors, to evaluate the simulation exercise. Results Fifty-one applicants representing all interviewees in the cycle successfully completed this assessment without technologic disruptions. The total cost associated with obtaining and providing the necessary supplies to applicants was $34.78 per interviewee. Time required to complete the suturing task was estimated to range from 10 to 20 minutes. The residency selection committee viewed this exercise as a success (14 of 16, 87.5%) and viewed the results as a valuable adjunct in the overall assessment of candidates (15 of 16, 93.8%). Conclusions A simple motor exercise completed over real-time telecommunication was feasible and perceived as helpful to the residency selection committee when assessing OHNS residency candidates.
