The effect of head of bed elevation on upper airway collapsibility during drug-induced sleep endoscopy.

STUDY OBJECTIVES: Drug-induced sleep endoscopy with positive airway pressure evaluates the collapsibility of the upper airway. It is currently unknown whether body position affects this assessment. We sought to determine whether the collapsibility of the airway may change with head of bed elevation. METHODS: A prospective, consecutive cohort study was performed by 2 sleep surgeons at a tertiary care center. Inclusion criteria included adults 18 years of age and older with obstructive sleep apnea who were intolerant to continuous positive airway pressure therapy. Patients underwent drug-induced sleep endoscopy with positive airway pressure to evaluate them for alternative treatment options. Patients were evaluated in supine position with the head of bed both level and elevated to 30°. The airway was evaluated using the standardized VOTE scoring system in both positions. RESULTS: The 61 patients included in the study were predominantly male (70.5%), middle-aged (51.2 years), and obese (body mass index, 30.2 kg/m2) with moderate-to-severe obstructive sleep apnea (apnea-hypopnea index, 34.1 events/h). The cohort consisted of predominantly positional obstructive sleep apnea (mean supine apnea-hypopnea index 48.7 events/h, nonsupine apnea-hypopnea index 20.8 events/h). All 4 sites of the upper airway demonstrated a significant decrease in airway opening pressures with the head of bed elevated compared to level (P < .01 for all sites). There was no significant difference in VOTE scoring between level and upright positions. CONCLUSIONS: Patients with the head of bed elevated to 30° have a significantly lower degree of airway collapsibility compared to patients in the level position but no significant change in VOTE scoring was observed.

Inpatient Otolaryngology Consultations and COVID-19: The Surge and Lasting Effects at an Urban, Academic Institution.

Objective: This study aims to examine the lasting effects of the coronavirus disease 2019 (COVID-19) pandemic on inpatient otolaryngology consultations. Methods: In a retrospective analysis, inpatient otolaryngology consultations at an urban, academic tertiary care center were reviewed over the course of 2 years (Jun 2019-Jun 2021). The consultations were categorized by time period based on the local data for COVID-19 hospitalizations and deaths as follows: pre-COVID (Jun 2019-Feb 2020), Surge 1 (Mar 2020-May 2020), Surge 2 (Oct 2020-Jan 2021), and Post Surge (Mar 2021-Jun 2021). Results: A total of 897 patients undergoing an inpatient otolaryngology consultation across all 4 time periods were included for analysis. The average consultations per day was 1.67 ± 0.24 in pre-COVID times, and dropped acutely to 0.86 ± 0.33 consultations per day during Surge 1. The consultation volume was not statistically different from pre-COVID levels during Surge 2 (1.33 ± 0.35) and Post Surge (1.60 ± 0.20). Reason for consultation and procedures performed did not vary significantly between pre-COVID times and Post Surge, except that consultation for postoperative complaint was less frequent in Post Surge (4.8% vs 1.0%, P = .02). More patients had been screened with rapid antigen COVID testing in Post Surge versus Surge 1 (20.1% vs 7.6%, P = .04). Conclusions: Inpatient otolaryngology consultation volumes, indications, and procedures performed at an urban, academic institution returned to pre-COVID levels after being significantly impacted during Surge 1.

Patients' Perceptions of Resident Surgeon Involvement in Otolaryngology.

OBJECTIVES: To assess patient acceptance of resident involvement in otolaryngologic procedures and to evaluate the impact of a written preoperative educational pamphlet. STUDY DESIGN: Prospective cohort study. METHODS: This is a prospective survey study at a large tertiary care academic center. In addition to standard perioperative instructions and informed consent, 87 out of 183 patients received a pamphlet with information on the role of the otolaryngology resident. RESULTS: Greater than 90% of all patients surveyed recognized that resident physicians are directly involved in delivering care at teaching hospitals and may have assisted in their surgical procedure. Ninety percent of patients receiving educational pamphlets were aware residents may have performed portions of their procedure versus 71% in the control group (P = .001). Ninety-seven percent of patients receiving pamphlets wanted to know how much of their procedure was performed by a resident versus 71% of the control group (P < .001), and patients undergoing single-surgeon procedures were less likely to want to know how much was performed by a resident (P < .05). Ninety-six percent in the pamphlet group agreed that residents improved the quality of their care versus 79% of the control group (P = .001). DISCUSSION: Resident surgeons are well received by the large majority of otolaryngology patients. Structured perioperative information regarding surgical training facilitates an honest and open informed consent discussion between the patient and surgeon and helps to establish a solid foundation of trust. CONCLUSION: Implementation of this practice is simple and inexpensive. It should be considered for any clinical practice with a focus on surgical education.

Rapid implementation of COVID-19 tracheostomy simulation training to increase surgeon safety and confidence.

OBJECTIVE: To determine if rapid implementation of simulation training for anticipated COVID-19 tracheostomy procedures can increase physician confidence regarding procedure competency and use of enhanced personal protective equipment (PPE). METHODS: A brief simulation training exercise was designed in conjunction with the development of a COVID-19 Tracheostomy Protocol. The simulation training focused primarily on provider safety, pre and post-surgical steps and the proper use of enhanced PPE. Simulation training was performed in the simulation lab at the institution over 2 days. Pre and post self-evaluations were measured using standardized clinical competency questionnaires on a 5-point Likert Scale ranging from "No knowledge, unable to perform" up to "Highly knowledgeable and confident, independent." RESULTS: Physicians self-reported a significant increase in knowledge and competency immediately after completing the training exercise. Resident physicians increased from a mean score of 3.00 to 4.67, p-value 0.0041, mean increase 1.67 (CI 95% 0.81 to 2.52). Attending physicians increased from a mean score of 2.89 to 4.67, p-value 0.0002, mean increase 1.78 (CI 95% 1.14 to 2.42). Overall, all participants increased from a mean score of 3.06 to 4.71, p-value 0.0001, mean increase 1.65 (CI 95% 1.24 to 2.05). DISCUSSION: Implementation of this simulation training at our institution resulted in a significant increase in physician confidence regarding the safe performance of tracheostomy surgery in COVID-19 patients. IMPLICATIONS FOR PRACTICE: Adoption of standardized COVID-19 tracheostomy simulation training at centers treating COVID-19 patients may result in improved physician safety and enhanced confidence in anticipation of performing these procedures in real-life scenarios.

Management of the Clinical and Academic Mission in an Urban Otolaryngology Department During the COVID-19 Global Crisis.

OBJECTIVE: The objective of this study was to assess the strategic changes implemented in the departmental mission to continue safe delivery of otolaryngology care and to support the broader institutional mission during the COVID-19 pandemic response. STUDY DESIGN: Retrospective assessment was performed to the response and management strategy developed to transform the clinical and academic enterprise. SETTING: Large urban tertiary care referral center. RESULTS: The departmental structure was reorganized along new clinical teams to effectively meet the system directives for provision of otolaryngology care and support for inpatient cases of COVID-19. A surge deployment schedule was developed to assist frontline colleagues with clinical support as needed. Outpatient otolaryngology was consolidated across the system with conversion of the majority of visits to telehealth. Operative procedures were prioritized to ensure throughput for emergent and time-critical urgent procedures. A tracheostomy protocol was developed to guide management of emergent and elective airways. Educational and research efforts were redirected to focus on otolaryngology care in the clinical context of the COVID-19 crisis. CONCLUSION: Emergence of the COVID-19 global health crisis has challenged delivery of otolaryngology care in an unparalleled manner. The concerns for preserving health of the workforce while ethically addressing patient career needs in a timely manner has created significant dilemmas. A proactive, thoughtful approach that reorganizes the overall departmental effort through provider and staff engagement can facilitate the ability to meet the needs of otolaryngology patients and to support the greater institutional mission to combat the pandemic.

Utilization of emergency department computed tomography and otolaryngology consultation in the diagnosis of pediatric peritonsillar abscess.

OBJECTIVES: To determine whether obtaining a computed tomography (CT) scan in the emergency department (ED) is predictive of peritonsillar abscess (PTA) in the pediatric population, and to evaluate for clinical characteristics that may suggest whether a CT is beneficial in the diagnosis of pediatric PTA. METHODS: Single-institution retrospective chart review at Rush University Hospitals. Study included pediatric patients, aged 17 or younger, who presented to the ED with suspected PTA over a 6-year period. Patients received a neck CT and/or an official otolaryngology consultation. Relevant demographic and study parameters were collected and statistically analyzed using SPSS. RESULTS: A total of 36 pediatric patients with suspected PTA. Of these, 47.2% (17/36) received a diagnosis of PTA while 52.8% (19/36) received an alternative diagnosis. Patients with PTA were more likely to have trismus (41.2% vs 5.3%; p < .01), uvular deviation (94.1% vs 15.8%; p < .01), and palatal edema (52.9% vs 10.5%; p < .01), compared to patients without PTA. Fewer CT scans were ordered when comparing PTA positive versus negative cohorts (35% vs 63.2%; p = .10), however this was not statistically significant. An otolaryngology consult prior to imaging did significantly reduce the frequency of ordered CT scans (12.5% vs 63.6%; p < .01). CONCLUSION: This is the first study to investigate the benefit of CT imaging in the diagnosis of pediatric PTA and impact of an otolaryngology consult on the frequency of CT scans. Pediatric patients at high risk for PTA based on clinical findings may not require CT imaging for diagnosis. Patients at lower risk may benefit from imaging based on the availability of an otolaryngology consult or expertise of the examiner.

Patients with chronic rhinosinusitis and obstructive sleep apnea have increased paroxysmal limb movement.

BACKGROUND: Patients with chronic rhinosinusitis (CRS) frequently experience sleep disruption and are at a higher than normal risk for obstructive sleep apnea (OSA). The purpose of this study was to determine how CRS affects polysomnography findings and sleep-related breathing in OSA. METHODS: A cohort study was performed that included 107 adult patients with CRS and comorbid OSA (CRS+OSA group) and 137 patients with OSA and without CRS as the control group. An electronic medical records database was used to identify eligible subjects. Comorbid conditions and polysomnography data were compared between the two groups by using logistic and linear regression analyses. RESULTS: A total of 246 patients were included: 107 patients in the CRS+OSA group and 137 patients with OSA and without CRS in the control group. After adjusting for demographic factors, the patients in the CRS+OSA group had a lower body mass index (BMI) and higher age at the time of diagnosis of OSA (p < 0.001). The patients in the CRS+OSA group had higher odds of having asthma and eczema. There was an increase in the periodic limb movement (PLM) index in the CRS+OSA group. Apnea and hypopnea indices were similar in the two groups. CONCLUSION: Patients with CRS developed OSA at a lower BMI; patients CRS and OSA had similar sleep-related breathing patterns but higher risks for PLMs compared with patients with OSA and without CRS.

A Case of Bilateral Atrophy of the Inferior Vestibular Nerves.

: We report a case of a 62-year-old woman who was found to have bilateral atrophy of the inferior vestibular nerves on magnetic resonance imaging (MRI) after presenting to our clinic with 6 years of intermittent vertigo and residual unsteadiness. The nerve atrophy may be associated with an episode of vestibular neuritis, a common cause of vertigo that exclusively involves the inferior vestibular nerve in less than 3% of cases. While MRI may demonstrate vestibular nerve enhancement in cases of acute vestibular neuritis, no single MRI finding has been demonstrated consistently among cases of acute or chronic vestibular neuritis. Physical therapy is likely an effective long-term treatment for this patient to achieve central compensation for symptomatic relief.

Risk of obstructive sleep apnea in African American patients with chronic rhinosinusitis.

BACKGROUND: It is widely known that patients with chronic rhinosinusitis (CRS) commonly experience sleep disruption. Many of these patients have the associated diagnosis of obstructive sleep apnea (OSA). However, little is known about the risk factors for developing OSA in the CRS population. OBJECTIVE: To identify the risk factors for OSA in CRS to determine who should be screened for OSA among patients with CRS. METHODS: We evaluated a large cohort of patients with confirmed diagnostic criteria for CRS. Patient medical records were reviewed to identify those with OSA confirmed by overnight polysomnography. Records were further reviewed for demographic information (age, sex, race, and ethnicity), body mass index, and medical history, including the presence of nasal polyps, asthma, aspirin-exacerbated respiratory disease, allergic rhinitis, and eczema. The number of endoscopic sinus operations, duration of CRS, presence of subjective smell loss, and computed tomography Lund-Mackay score were also ascertained. RESULTS: A total of 916 patients with CRS were included in the study. Implementation of a multivariable regression model for identifying adjusted risk factors revealed that African American patients had a significantly higher risk for OSA than white patients, with an adjusted odds ratio of 1.98 (95% confidence interval, 1.19-3.29). Furthermore, patients with CRS without nasal polyps were at higher risk for OSA, with an odds ratio of 1.63 (95% confidence interval, 1.02-2.61) compared with patients with CRS with nasal polyps. CONCLUSION: African American patients with CRS were at higher risk for OSA compared with white patients, and this patient group needs to be screened for OSA.
