RESUMEN

Objectives: To evaluate trends in botulinum toxin (BTX) industry payments to physicians. Methods: Cross-sectional analysis of nonroyalty, BTX-specific payments made by Allergan (Botox), Ipsen (Dysport), and Merz (Xeomin) to physicians using the 2016-2020 Open Payments Database. Results: Between 2016 and 2020, >$27 million in payments was made for BTX-related activities to dermatologists, neurologists, ophthalmologists, otolaryngologists, and plastic surgeons, with payments ranging from $3.9 million in 2016 to $8.7 million in 2019. 21.7% was paid to dermatologists, 57.5% to neurologists, 5.9% to ophthalmologists, 5.7% to otolaryngologists, and 9.1% to plastic surgeons. Conclusions: Growing amounts are being paid to physicians for BTX-related activities-both medical and aesthetic. Despite the variety of indications for BTX within otolaryngology, otolaryngology payments were overshadowed by other specialties, which may reflect greater BTX utilization in those specialties.

RESUMEN

OBJECTIVE: Evaluate the effect of treatment delay on survival in human papillomavirus (HPV)-positive and HPV-negative oropharyngeal squamous cell carcinoma (OPSCC) patients undergoing primary surgical resection. STUDY DESIGN: Retrospective cohort study using the 2010-2017 National Cancer Database. SETTING: Multicenter database study. METHODS: Patients >18 years old with OPSCC and known HPV status, treated surgically with or without postoperative radiation/chemotherapy were included. Two cohorts based on HPV status were grouped by time to treatment initiation (TD-TI, ≤30, 31-60, ≥61 days) and surgery to radiotherapy (TS-RT, ≤42, 43-66, ≥67 days). Univariate, Kaplan-Meier, and multivariate analyses assessed correlations between demographic and clinical factors with overall survival in treatment delay groups. RESULTS: Included were 1643 HPV-positive OPSCC patients and 391 HPV-negative OPSCC patients. No associations between survival and gender, age, race, insurance, or radiotherapy length were observed. Regardless of HPV status, larger tumor size (>2 cm) and lymphovascular invasion predicted worse survival. HPV negative patients with >4 lymph nodes involved had 2.5× greater mortality risk (P = .039). Robotic surgery was associated with improved survival only in HPV positive patients (hazard ratio [HR]: 0.41, P < .001). In HPV positive patients, higher TD-TI related to lower mean survival, although this was not significant on multivariate analysis. HPV negative patients with >42 days of TS-RT had decreased survival (43-66 days, HR 1.63, P = .049; ≥67 days, HR 2.10, P = .032). CONCLUSION: Longer TS-RT was associated with lower overall survival in HPV negative patients. Treatment delay was not associated with survival in HPV positive OPSCC according to multivariate analysis. These findings enhance knowledge about treatment delay effects in OPSCC, aiding providers in decisions and patient communication.

RESUMEN

Background: A "boomerang" graft is an end-to-end caudal septal extension graft (SEG) that conforms to the geometry of the anterior septal angle, and avoids septal overlap, unlike a side-to-side SEG. Objective: To compare breathing improvements in rhinoplasty patients receiving boomerang SEGs and patients receiving side-to-side SEGs. Methods: Retrospective cohort analysis of patients undergoing rhinoplasty with either end-to-end boomerang SEG or a side-to-side SEG. Functional outcomes were assessed through the Nasal Obstruction Symptom Evaluation (NOSE) survey. Results: The boomerang SEG cohort had a mean age of 34 years and were 68% female compared with 38 years and 67% female in the side-to-side SEG cohort (p > 0.05). The cohorts did not differ in the proportion of the lateral crural tensioning, spreader graft placement, or history of rhinoplasty. The boomerang cohort demonstrated a 67% reduction in NOSE scores compared with a 70% reduction among the side-to-side SEG cohort (p = 0.14). Men undergoing boomerang graft placement reported significantly less postoperative functional improvement than men undergoing placement of a side-to-side SEG (62% vs. 77%, p = 0.01). Conclusion: Use of a boomerang graft is not likely to negatively affect rhinoplasty functional outcomes when compared with a side-to-side SEG.

RESUMEN

OBJECTIVE: Frailty metrics estimate a patient's ability to tolerate physiologic stress and there are limited frailty data in patients undergoing expanded endonasal approaches (EEA) for suprasellar pathologies. Elevated frailty metrics have been associated with increased perioperative complications in patients undergoing craniotomies. We sought to examine this potential relationship in EEA. STUDY DESIGN: Retrospective cohort study. SETTING: Two tertiary academic skull base centers. METHODS: Cases of patients undergoing EEA for suprasellar pathologies were reviewed. Demographic, treatment, survival, and postoperative outcomes data were recorded. Frailty was calculated using validated indexes, including the American Society of Anesthesiologists (ASA) classification, the modified 5-item frailty index (mFI-5), and the Charlson comorbidity index (CCI). Primary outcomes included 30-day medical and surgical complications. RESULTS: A total of 88 patients were included, with 59 (67%) female patients and a mean age of 54 ± 15 years. The most common pathologies included 53 meningiomas (60.2%) and 21 craniopharyngiomas (23.9%). Most patients were ASA class 3 (54.5%) with mean mFI-5 0.82 ± 1.01 and CCI 4.18 ± 2.42. There was no association between increased frailty and 30-day medical or surgical outcomes (including postoperative cerebrospinal fluid leak), prolonged length of hospital stay, or mortality (all P > .05). Higher mFI-5 was associated with an increased risk for 30-day readmission (odds ratio: 2.35, 95% confidence Interval: 1.10-5.64, P = .04). CONCLUSION: Despite the patient population being notably frail, we only identified an increased risk for 30-day readmission and observed no links with deteriorating surgical, medical, or mortality outcomes. This implies that conventional frailty metrics may not effectively align with EEA outcomes.

RESUMEN

Objective: To explore if antiplatelet or anticoagulant therapy increases the risk of transfusion requirement or postoperative hematoma formation in patients undergoing microvascular reconstruction for head and neck defects. Study Design: Retrospective cohort study. Setting: Departments of Otolaryngology-Head and Neck Surgery at the University of Alabama at Birmingham, the University of Colorado, and the University of California Irvine. Methods: A multi-institutional, retrospective review on microvascular reconstruction of the head and neck between August 2013 to July 2021. Perioperative antithrombotic data were collected to examine predictors of postoperative transfusion and hematoma. Results: A total of 843 free flaps were performed. Preoperative hemoglobin, hematocrit, operative time, and flap type were positive predictors of postoperative transfusion in both bivariate (P < .0001) and multivariate analyses (P < .0001). However, neither anticoagulation nor antiplatelet therapy were predictive of postoperative transfusion rates and hematoma formation. Conclusion: Antithrombotic regimens do not increase the risk of postoperative transfusion or hematoma in head and neck microvascular reconstruction. Based on this limited data, perioperative antithrombotic regimens can be considered in patients who may otherwise be at risk for these postoperative complications.

RESUMEN

In a survey of infection prevention programs, leaders reported frequent clinical and infection prevention practice modifications to avoid coronavirus disease 2019 (COVID-19) exposure that exceeded national guidance. Future pandemic responses should emphasize balanced approaches to precautions, prioritize educational campaigns to manage safety concerns, and generate an evidence-base that can guide appropriate infection prevention practices.

RESUMEN

OBJECTIVES: As research in otolaryngology continues to expand rapidly, it is important to identify core journals to keep clinicians updated with the latest advances. This study is the first to characterize core journals in otolaryngology. METHODS: Using h-index and impact factor (IF), the top 15 NLM-indexed otolaryngology journals were selected for analysis. The references from all articles published in these journals in one randomized quarter were compiled into a citation rank list, with the most cited journal ranked the highest. Citation zonal distribution analysis was conducted to identify the zonal distribution of otolaryngology journals. RESULTS: A total of 3150 journals containing 26876 articles were cited in otolaryngology literature in April-June 2019. Laryngoscope was the most cited journal containing 1762 citations. IF is significantly associated with the h-index for the top 10 otolaryngology journals (p = 0.032). Three core journal zones were identified, with Zone 1 containing 8 journals, Zone 2 containing 36 journals, and Zone 3 containing 189 journals. A linear relationship between the log journal rank for Zones 1-3 and a cumulative number of citations was found (R2 = 0.9948). CONCLUSION: Eight core journals for otolaryngology were identified: Laryngoscope, Otolaryngology-Head and Neck Surgery, Otology & Neurotology, JAMA Otolaryngology-Head & Neck Surgery, Head & Neck, European Archives of Oto-Rhino-Laryngology, International Journal of Pediatric Otorhinolaryngology, Annals of Otology, Rhinology & Laryngology. In the face of rapidly evolving research and a multitude of journals, the high citation density within these core journals highlights their utility in updating busy clinicians. LEVEL OF EVIDENCE: NA Laryngoscope, 133:3346-3352, 2023.

RESUMEN

BACKGROUND: The high prescription drug cost in the United States may negatively affect patient prognosis and treatment compliance. OBJECTIVE: To fill the knowledge gap and inform clinicians regarding rhinology medications price changes by evaluating trends in price changes of highly used nasal sprays and allergy medications. METHODS: The 2014-2020 Medicaid National Average Drug Acquisition Cost database was queried for drug pricing information for the following classes of medications: intranasal corticosteroids, oral antihistamines, antileukotrienes, intranasal antihistamines, and intranasal anticholinergics. Individual medications were identified by Food and Drug Administration-assigned National Drug Codes. Per unit, drug prices were analyzed for average annual prices, average annual percentage price changes, and inflation-adjusted annual and composite percentage price changes. RESULTS: Beclometasone (Beconase AQ, 56.7%, QNASL, 77.5%), flunisolide (Nasalide, -14.6%), budesonide (Rhinocort Aqua, -1.2%), fluticasone (Flonase, -6.8%, Xhance, 11.7%), mometasone (Nasonex, 38.2%), ciclesonide (Omnaris, 73.8%), combination azelastine and fluticasone (Dymista, 27.3%), loratadine (Claritin, -20.5%), montelukast (Singulair, 14.5%), azelastine (Astepro, 21.9%), olopatadine (Patanase, 27.3%), and ipratropium bromide (Atrovent, 56.6%) had an overall change in inflation-adjusted per unit cost between 2014 and 2020 (% change). Of 14 drugs evaluated, 10 had an increase in inflation-adjusted prices, for an average increase of 42.06% ± 22.27%; 4 of 14 drugs had a decrease in inflation-adjusted prices, for an average decrease of 10.78% ± 7.36%. CONCLUSION: The rising cost of highly used medications contributes to increased patient acquisition costs and may pose barriers of drug adherence to particularly vulnerable populations.

RESUMEN

OBJECTIVES: We aim to evaluate the impact of MetS on the short-term postoperative outcomes of complex head and neck surgery patients. METHODS: This is a retrospective cohort analysis of the 2005 to 2017 National Surgical Quality Improvement Program (NSQIP) database. NSQIP database was queried for 30-day outcomes of patients undergoing complex head and neck surgeries, defined as laryngectomy or mucosal resection followed by free tissue transfer, similar to prior NSQIP studies. Patients with hypertension, diabetes, and body mass index (BMI) >30 kg/m2 were defined as having MetS. Adverse events were defined as experiencing readmission, reoperation, surgical/medical complications, or mortality. RESULTS: A total of 2764 patients (27.0% female) with a mean age of 62.0 ± 11.7 years were included. Patients with MetS (n = 108, 3.9%) were more likely to be female (P = .017) and have high ASA classification (P = .030). On univariate analysis, patients with MetS were more likely to require reoperation (25.9% vs 16.7%, P = .013) and experience medical complications (26.9% vs 15.4% P = .001) or any adverse events (61.1% vs 48.7%, P = .011) compared to patients without MetS. On multivariate logistic regression after adjusting for age, sex, race, ASA classification, and complex head and neck surgery type, MetS was an independent predictor of medical complications (odds ratio 2.34, 95% CI 1.28-4.27, P = .006). CONCLUSION: Patients with MetS undergoing complex head and neck surgery are at increased risk of experiencing medical complications. Identifying patients with MetS can therefore aid surgeons in preoperative risk assessment and help improve postoperative management. LEVEL OF EVIDENCE: N/A.

RESUMEN

OBJECTIVE: To determine if antithrombotic therapy improves head and neck microvascular free flap survival following anastomotic revision. STUDY DESIGN: A retrospective review of all patients with microvascular free tissue transfer to the head and neck between August 2013 and July 2021. SETTING: Otolaryngology-Head and Neck Surgery Departments at University of Alabama at Birmingham, University of Colorado, and University of California Irvine. METHODS: Perioperative use of anticoagulation, antiplatelets, intraoperative heparin bolus, tissue plasminogen activator (tPA) and vasopressor use, and leech therapy were collected plus microvascular free flap outcomes. The primary endpoint was free flap failure. Analyses of free flaps that underwent anastomotic revision with or without thrombectomy were performed. RESULTS: A total of 843 microvascular free flaps were included. The overall rate of flap failure was 4.0% (n = 34). The overall rate of pedicle anastomosis revision (artery, vein, or both) was 5.0% (n = 42) with a failure rate of 47.6% (n = 20) after revision. Anastomotic revision significantly increased the risk of flap failure (odds ratio [OR] 52.68, 95% confidence interval [CI] [23.90, 121.1], p < .0001) especially when both the artery and vein were revised (OR 9.425, 95% CI [2.117, 52.33], p = .005). Free flap failure after the anastomotic revision was not affected by postoperative antiplatelet therapy, postoperative prophylactic anticoagulation, intraoperative heparin bolus, tPA, and therapeutic anticoagulation regardless of which vessels were revised and if a thrombus was identified. CONCLUSION: In cases of microvascular free tissue transfer pedicle anastomotic revision, the use of antithrombotic therapy does not appear to significantly change free flap survival outcomes.

RESUMEN

BACKGROUND: Acute invasive fungal sinusitis (AIFS) is an aggressive disease that requires prompt diagnosis and multidisciplinary treatment given its rapid progression. However, there is currently no consensus on diagnosis, prognosis, and management strategies for AIFS, with multiple modalities routinely employed. The purpose of this multi-institutional and multidisciplinary evidence-based review with recommendations (EBRR) is to thoroughly review the literature on AIFS, summarize the existing evidence, and provide recommendations on the management of AIFS. METHODS: The PubMed, EMBASE, and Cochrane databases were systematically reviewed from inception through January 2022. Studies evaluating management for orbital, non-sinonasal head and neck, and intracranial manifestations of AIFS were included. An iterative review process was utilized in accordance with EBRR guidelines. Levels of evidence and recommendations on management principles for AIFS were generated. RESULTS: A review and evaluation of published literature was performed on 12 topics surrounding AIFS (signs and symptoms, laboratory and microbiology diagnostics, endoscopy, imaging, pathology, surgery, medical therapy, management of extrasinus extension, reversing immunosuppression, and outcomes and survival). The aggregate quality of evidence was varied across reviewed domains. CONCLUSION: Based on the currently available evidence, judicious utilization of a combination of history and physical examination, laboratory and histopathologic techniques, and endoscopy provide the cornerstone for accurate diagnosis of AIFS. In addition, AIFS is optimally managed by a multidisciplinary team via a combination of surgery (including resection whenever possible), antifungal therapy, and correcting sources of immunosuppression. Higher quality (i.e., prospective) studies are needed to better define the roles of each modality and determine diagnosis and treatment algorithms.

RESUMEN

OBJECTIVE: Topical intranasal anticholinergics are commonly prescribed for the relief of chronic rhinitis and associated symptoms, warranting thorough assessment of the supporting evidence. The present study aimed to evaluate the safety and efficacy of anticholinergic nasal sprays in the management of allergic and non-allergic rhinitis symptom severity and duration. METHODS: A search encompassing the Cochrane Library, PubMed/MEDLINE, and Scopus databases was conducted. Primary studies describing rhinorrhea, nasal congestion, and/or postnasal drip outcomes in rhinitis patients treated with an anticholinergic spray were included for review. RESULTS: The search yielded 1,029 unique abstracts, of which 12 studies (n = 2,024) met inclusion criteria for qualitative synthesis and 9 (n = 1,920) for meta-analysis. Median follow-up was 4 weeks and ipratropium bromide was the most extensively trialed anticholinergic. Compared to placebo, anticholinergic treatment was demonstrated to significantly reduce rhinorrhea severity scores (standardized mean difference [95% CI] = -0.77 [-1.20, -0.35]; -0.43 [-0.72, -0.13]) and duration (-0.62 [-0.95, -0.30]; -0.29 [-0.47, -0.10]) in allergic and non-allergic rhinitis patients respectively. Benefit was less consistent for nasal congestion, postnasal drip, and sneezing symptoms. Reported adverse effects included nasal mucosa dryness or irritation, epistaxis, headaches, and pharyngitis, though comparison to placebo found significantly greater risk for epistaxis only (risk ratio [95% CI] = 2.19 [1.22, 3.93]). CONCLUSION: Albeit treating other symptoms with less benefit, anticholinergic nasal sprays appear to be safe and efficacious in reducing rhinorrhea severity and duration in both rhinitis etiologies. This evidence supports their continued use in the treatment of rhinitis-associated rhinorrhea. LEVEL OF EVIDENCE: 1 Laryngoscope, 133:722-731, 2023.

RESUMEN

Background: Rhinoplasty osteotomes can be sharpened in various ways: professional sharpening or hand sharpening using whetstones or rotary powered devices. Objective: To compare the effectiveness of sharpening osteotomes using various sharpening methods with that of professional sharpening as measured by a custom edge tester. Materials and Methods: We performed repeated serial osteotome impacts on bovine femoral cortical bone. These dull osteotomes were sharpened using preidentified sharpening techniques. Edge morphology was evaluated. Sharpness was tested using a custom mechanical testing platform. Optimized sharpness was achieved with a whetstone sharpening method wherein the osteotome is flipped after every stroke. Results: Seven distinct sharpening methods were tested for sharpness five times each to determine the optimal sharpening method versus professional sharpening (control). The two sharpening methods, 5 (5.51 ± 0.32) and 6 (5.55 ± 0.32), that used this flipping technique were significantly sharper than other methods. Methods 5 (p = 1.0) and 6 (p = 1.0) were the only methods that were not significantly different from control. Conclusion: Single stroke with successively alternating surfaces created the sharpest blades that achieved results similar to professional sharpening.

RESUMEN

Recent studies provide conflicting evidence on the persistence of SARS-CoV-2 immunity induced by mRNA vaccines. Here, we aim to quantify the persistence of humoral immunity following vaccination using a coronavirus antigen microarray that includes 10 SARS-CoV-2 antigens. In a prospective longitudinal cohort of 240 healthcare workers, composite SARS-CoV-2 IgG antibody levels did not wane significantly over a 6-month study period. In the subset of the study population previously exposed to SARS-CoV-2 based on seropositivity for nucleocapsid antibodies, higher composite anti-spike IgG levels were measured before the vaccine but no significant difference from unexposed individuals was observed at 6 months. Age, vaccine type, or worker role did not significantly impact composite IgG levels, although non-significant trends towards lower antibody levels in older participants and higher antibody levels with Moderna vaccine were observed at 6 months. A small subset of our cohort were classified as having waning antibody titers at 6 months, and these individuals were less likely to work in patient care roles and more likely to have prior exposure to SARS-CoV-2.
