Abstract Introduction Dual eligible beneficiaries are a vulnerable population who often experience inferior access to care and outcomes compared to non‐dual eligible beneficiaries. The Oncology Care Model (OCM) is an alternative payment model that aims to improve coordination and quality of care in beneficiaries receiving chemotherapy and thus may improve care for dual eligible beneficiaries with cancer. Methods We used 100% Medicare claims data from 2014 through 2019 and included beneficiaries with bladder, breast, esophageal, colorectal, kidney, lung, pancreatic, or prostate cancer receiving chemotherapy. We constructed multivariable difference‐in‐differences regression models to evaluate the effect of OCM participation on healthcare utilization and quality of care at the end‐of‐life among dual eligible beneficiaries. We also compared healthcare utilization and quality of care outcomes to non‐dual eligible beneficiaries. Results We identified 3,043,944 episodes of care among 1,260,892 unique Medicare beneficiaries. Ten percent of all beneficiaries (n = 126,758) were dual eligible and 64,087 (22%) of episodes among dual eligible patients were in an OCM participating practice. We noted no effect of OCM participation on healthcare utilization or end‐of‐life quality of care for dual eligible beneficiaries. However, we observed higher rates of hospitalization, emergency department visits, intensive care unit stays, and a lower number of office visits among dual eligible beneficiaries compared to non‐dual eligible beneficiaries. Conclusions Participation in OCM was not associated with improvements in quality of care or healthcare utilization for dual eligible beneficiaries. Dual eligible beneficiaries experience lower quality of care across several measures compared to non‐dual eligible beneficiaries. Focused policies and incentives may be necessary to address disparities within emerging health reforms.

Objective: To measure postoperative airway volumes among patients with craniofacial abnormalities and compare them to normative values., Study Design: Retrospective, comparative study., Setting: Academic Medical Center., Methods: Retrospective analysis of imaging of children with craniofacial abnormalities treated at NYU Langone Health from January 2013 to February 2021. Upper airway volumes postcraniofacial surgery were measured using 3D processing software (Dolphin 3D, version 11.95). These values were compared with published normative values., Results: Twenty-one subjects were identified and compared to normative values. The postoperative oropharyngeal volumes were on average 43.7% smaller than the normative values (P < .001), and the total upper airway volumes were 31.6% smaller (P = .003). No significant differences were observed in the nasopharyngeal or hypopharyngeal volumes of the study cohort compared to the normative data. Among children ages 12 to 17 years (n = 13), the mean oropharyngeal volumes were 47.6% smaller than normal (P < .001), and the mean total upper airway volumes were 34.6% smaller than normal (P < .001). Among children ages 7 to 11 years (n = 8), the mean oropharyngeal volumes were 35.1% smaller than normal (P = .049), but no difference in mean total upper airway volume was observed., Conclusion: In children with craniofacial anomalies, postoperative airway volumes remain lower than normative values. However, even a slight increase in airway volume can yield a substantial increase in flow rate. 3D airway evaluations are a valuable tool for surgical planning and analysis and can help with optimizing airway dynamics., (© 2024 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

Introduction: Retraction pockets and marginal perforations of the pars tensa of the tympanic membrane (TM) are most commonly found at superior posterior quadrant (SPQ). The patulous Eustachian tube tends to manifest in the same quadrant. Variation in the structure of the TM may explain these observations., Material and Methods: A line defined by the manubrium was used to divide the pars tensa into anterior and posterior portions. A transverse line centered on the umbo divides the pars tensa into superior and inferior parts, resulting in four quadrants. Surface areas of each of the TM quadrants were measured in a sample of 23 human adult formalin-fixed temporal bones. The TMs were completely excised, faced medially, and placed against graph paper to maintain scale measurements, photoed, and measured.TM thickness was measured on a different set of 20 human temporal bones (TB) preparations with normal external and middle ears. Four random loci were chosen from each pars tensa's TM quadrant. The thickness was measured using high-magnification power microscopy., Results: The SPQ was the largest and thinnest of the four quadrants. It occupies 31% of the pars tensa area. It is 69 μm as compared to approximately 85 μm in the other quadrants. The radial lines between the umbo and the annulus are in descending order from superior posterior toward the anterior-superior radials., Conclusion: The SPQ has the largest vibratory area and is the thinnest of the four TM quadrants. Variation in the thickness of the middle, fibrous layer accounts for the variation in the thickness of the TM. These findings may explain the tendency of pathologies related to Eustachian tube dysfunction to preferentially manifest in or originate from the SPQ., Competing Interests: The authors declare no conflict of interest., (© 2022 The Authors.

Objectives: To determine the difference in bleeding when extracapsular tonsillectomy with electrocautery is performed on the dominant and nondominant side of the surgeon's hands., Study Design: Retrospective cohort study., Setting: Academic university hospital., Methods: Medical record data of patients who were admitted with posttonsillectomy bleeding from January 1, 2000, to July 31, 2017, were reviewed. Included were age, sex, surgical indication, side of posttonsillectomy bleeding, and time of bleeding. Information on the surgeon's dominant hand was also collected. All patients underwent total extracapsular resection with electrocautery., Results: Of 280 patients, 186 met the inclusion criteria, 116 (62.3%) males and 70 (37.7%) females. Ages ranged from 2 to 74 years (mean ± SD, 17 ± 13 years; median, 13 years). In 136 cases (73.1%), bleeding was on the side of the surgeon's nondominant hand ( P < .0001). In 50 (26.9%) cases, bleeding was on the side of the surgeon's dominant hand. The odds ratio of bleeding on the side of the surgeon's nondominant hand compared to the dominant hand was 8.99., Conclusion: The risk of bleeding following extracapsular tonsillectomy with electrocautery on the side of the surgeon's nondominant hand is significantly higher than on the side of the dominant hand. Thus, additional caution is required when operating on the nondominant side of the oral cavity in extracapsular tonsillectomy using electrocautery. These findings raise questions regarding dexterity as a risk factor for posttonsillectomy bleeding.

Objective: The coronavirus disease 2019 (COVID-19) pandemic poses a threat to global health. Early diagnosis is an essential key to limit the outbreak of the virus., Study Design: Case series, study conducted between March 25, 2020, and April 15, 2020., Setting: Ambulatory, nonhospitalized patients who were quarantined in a designated hotel for COVID-19 patients and were recruited by an advertisement at the hotel., Subjects and Methods: In total, 140 patients participated in a web-based questionnaire assessing initial symptoms of common viral diseases, olfactory and taste functions, xerostomia, and orofacial pain., Results: A total of 58 men and 70 women participated. Initial symptoms were cough (59.4%), weakness (47.7%), myalgia (46.9%), fever (42.2%), headache (40.6%), impaired sense of smell (38.3%), impaired sense of taste (32.8%), sore throat (26.6%), runny nose (26.6%), and nasal congestion (22.7%). All symptoms were more frequent among women; however, only runny nose was statistically significant ( P = .018). The most common combination of symptoms was cough and weakness (37.5%). A total of 25.8% reported olfactory and taste dysfunctions in the absence of other symptoms. In a comparison between the sexes, cough and runny nose were the most common combination in women ( P = .018). A total of 38.3% of patients reported olfactory dysfunction as an initial symptom. Anosmia and facial pain were more common among women ( P < .001 and P = .01, respectively), and 56% of patients reported xerostomia., Conclusion: A considerable number of patients presented with olfactory and oral disorders. Interestingly, women presented with a different cluster of symptoms than men, which may suggest a new clinical approach to diagnosing COVID-19 disease.

Objective: To study the full panoramic view with figuring of the morphology and topography of the human tympanic annulus., Study Design: Postmortem material analysis., Setting: University-affiliated hospital., Subjects and Methods: Twenty-three single, normal human adult tympanic membranes were completely extracted from formalin-fixed temporal bones. They were faced medially and placed at the same level of a graph paper mounted on a board. High-quality images of the tissue preparations were taken, and computer-aided measurements of the annular caliber were calculated at nine reference points. The 6 o'clock direction served as a midpoint, and another four reference points were set anteriorly and posteriorly in clockwise and counterclockwise directions., Results: The annulus has a horseshoe-like shape with a small part absent above the neck of the malleus. The maximal mean caliber at the manubrial axis (6 o'clock direction) was 748 +/- 201 mum. The annulus gradually thins out almost symmetrically anteriorly and posteriorly, until it reaches about 15 percent of the maximal caliber at its end points (152 +/- 87 and 113 +/- 42 mum, respectively). Significant differences were found between adjacent reference points on both anterior and posterior sides., Conclusions: The annulus has a horseshoe-like shape and gradually thins out almost symmetrically, reaching anteriorly and posteriorly about 15 percent of the maximal caliber at the manubrial axis. These new data may provide guidance in transcanal middle ear exploration and suggest the possibility of varied functions attributable to the annulus regarding middle ear sound transmission and TM vibratory properties. The data may contribute to understanding the development of marginal perforations and posterior superior retraction pockets., (Copyright 2010 American Academy of Otolaryngology-Head and Neck Surgery Foundation.
