Objective: To determine in-hospital costs associated with performing an EEA to anterior skull base pathology and to identify drivers of cost variability for patients undergoing endoscopic anterior skull base surgery. Methods: All endoscopic anterior skull base surgeries performed over a period from January 1st, 2015 to October 24th, 2017 were evaluated. The electronic medical record was reviewed for patient factors, tumor characteristics, and cost variables associated with each hospital stay and univariate analysis was performed using Stata software. Results: An EEA was associated with an average total in-hospital cost of $44 545. Compared to patients undergoing a transsphenoidal approach to pituitary tumor resection, EEA patients incurred higher in-hospital costs across all variables including a total cost increase of $15 921 (95% confidence interval $5720-26 122, P =.002). Univariate analysis of all endoscopic anterior skull base surgery patients showed a cost increase of $30 616 associated with post-operative cerebrospinal fluid (CSF) leak ($10 420-50 811, P =.004), $14 610 with post-operative diabetes insipidus (DI) ($4610-24 609, P =.004), and $11 522 with African-American patients relative to Caucasian patients ($3049-19 995, P =.008). Conclusions: Patients who undergo endoscopic EEA for resection of anterior skull base tumors typically incur greater in-hospital costs than patients undergoing a standard TSA. Post-operative complications such as CSF leak and DI, as well as ethnicity, are significant drivers of cost-variability. [ABSTRACT FROM AUTHOR]

Background: Dupilumab is a novel monoclonal antibody that recently received US Food and Drug Administration approval for the treatment of chronic rhinosinusitis with nasal polyps. Endoscopic sinus surgery (ESS) has been the mainstay of treatment for patients refractory to initial medical therapy. Data comparing the cost‐effectiveness of these treatments are scarce. The objective of this study is to compare the cost‐effectiveness of dupilumab and ESS treatment for patients with chronic rhinosinusitis with nasal polyps refractory to medical therapy. Methods: A cohort‐style Markov decision tree economic evaluation with 10‐year time horizon was performed. The two comparative treatment strategies were dupilumab therapy or ESS followed by postoperative maintenance therapy. Patients with response to treatment continued with either maintenance or dupilumab therapy; patients with no response underwent ESS. The primary outcome measure was incremental cost per quality‐adjusted life‐year calculated from Sino‐Nasal Outcome Test (SNOT‐22) scores. Sensitivity analyses were performed including discounting scenarios and a probabilistic sensitivity analysis. Results: The dupilumab strategy cost $195,164 and produced 1.779 quality‐adjusted life‐years. The ESS strategy cost $20,549 and produced 1.526 quality‐adjusted life‐years. This implies an incremental cost of $691,691 for dupilumab for every 1‐unit increase in quality‐adjusted life‐year compared with ESS. Probability sensitivity analysis indicated that ESS was more cost‐effective than dupilumab in all iterations. Conclusions: While dupilumab and ESS may demonstrate similar clinical effectiveness, ESS remains the most cost‐effective treatment option and should remain the standard of care for patients with chronic rhinosinusitis with nasal polyps refractory to medical therapy.

Background: Sinonasal posttransplant lymphoproliferative disorder (PTLD) is a serious but uncommon complication of solid organ and hematopoietic stem cell transplantation that can overlap in many features with invasive fungal sinusitis (IFS).Objective: To identify clinical, laboratory, and radiographic features that may help to differentiate sinonasal IFS and PTLD in the posttransplant population.Methods: We performed a retrospective chart review of patients with posttransplant sinonasal PTLD and IFS to evaluate for clinical, laboratory, and imaging characteristics.Results: A total of 4 patients with sinonasal PTLD and 10 posttransplant IFS patients were evaluated. A total of 2 of 4 PTLD patients presented with a symptom duration of greater than 3 months compared to none in the IFS group (p = 0.07). Mean absolute neutrophil count (ANC) was 2,976 per mm3 (range 2,488-3,462) in the PTLD group compared to 773 per mm3 (range 0.0-2,744) in the IFS group (p = 0.01). Both PTLD lesions with available diffusion-weighted imaging demonstrated diffusion restriction on magnetic resonance im-aging (MRI) compared to zero of the IFS lesions (p = 0.10). No PTLD lesions demonstrated mucosal infarcts compared to three of seven IFS lesions (p = 0.23).Conclusion: IFS was associated with a significantly lower ANC at the time of diagnosis compared to PTLD. Additionally, three other measures trend towards association with their respective pathology. PTLD typically has a more chronic time course than IFS, diffusion restriction on MRI is predominantly associated with PTLD patients, and mucosal infarct on MRI is more suggestive of IFS. Additionally, all cases of sinonasal PTLD arose following solid organ transplantation. These factors may assist clinicians during diagnosis. [ABSTRACT FROM AUTHOR]- Published

Background: Aspirin‐exacerbated respiratory disease (AERD) is characterized by chronic eosinophilic rhinosinusitis, nasal polyps, asthma, and respiratory sensitivity to aspirin and nonsteroidal anti‐inflammatory drugs (NSAIDs). In addition to sensitivity to aspirin and NSAIDs, the majority of patients with AERD have been reported to have respiratory intolerance associated with the consumption of alcohol. Methods: A multicenter prospective cohort study was performed. Patients with AERD confirmed by aspirin challenge were eligible to participate. Those who described themselves as able to tolerate alcohol consumption were excluded. Patients underwent aspirin desensitization following endoscopic sinus surgery. A questionnaire was distributed to patients before and after desensitization to determine pre‐desensitization and post‐desensitization symptoms associated with alcohol ingestion. Results: Forty‐five patients were enrolled and 37 patients completed the study. The most common pre‐desensitization symptoms were nasal congestion (95.6%), rhinorrhea (46.7%), and wheezing (40%). Improvement in the ability to tolerate alcohol was noted in 86.5% of participants (95% confidence interval [CI], 75.5% to 97.5%) and 70.3% of participants (95% CI, 55.5% to 85.0%) described desensitization to be “very helpful” or “extremely helpful” for their ability to tolerate alcohol. Conclusion: The majority of patients with AERD who experience respiratory symptoms with alcohol consumption describe improvement in this domain following aspirin desensitization.

Background Improvement in topical delivery to nasal mucosa is a fundamental goal of endoscopic sinus surgery (ESS). This study compares the penetration of irrigation before and after middle turbinate resection (MTR) to assess the efficacy of topical delivery. Methods ESS was performed on 4 cadaver heads, followed by MTR. Each head was irrigated with fluorescein-dyed water using a squeeze bottle both before and after MTR. Videos were recorded by rigid nasal endoscopy. Four blinded raters reviewed videos and scored the extent of staining (0 to 3) for each site. Results The mean score for the extent of staining of all anatomical sites before and after MTR was 1.30 and 1.92, respectively ( p = 0.035). The mean score for extent of staining before and after MTR was 2.56 and 2.81 ( p = 0.134) for the maxillary sinus, 1.66 and 2.25 ( p = 0.022) for the ethmoid sinus, 1.03 and 1.94 ( p = 0.263) for the sphenoid sinus, 0.16 and 0.94 ( p = 0.055) for the frontal sinus, and 1.09 and 1.66 ( p = 0.340) for the olfactory cleft, respectively. When evaluating interrater reliability, Cronbach's alpha was 0.92, which is acceptable. When evaluating intrarater reliability, the Fleiss kappa statistic for each rater was excellent or good. Conclusion Overall, MTR results in significant improvement in the penetration of nasal irrigations in the cadaver model. Each individual sinus displays a trend toward improvement; however, only the ethmoid sinus displays a statistically significant improvement. Further in vivo studies are needed to elucidate the role of MTR. [ABSTRACT FROM AUTHOR]

Background: High-resolution microendoscopy (HRME) enables real-time imaging of epithelial tissue. The utility of this novel imaging modality for inverted papilloma has not been previously described. This study examines the ability of otolaryngologists to differentiate between images of inverted papilloma and normal sinonasal mucosa obtained with a HRME. Methods: Inverted papilloma and normal sinonasal mucosa specimens were stained with a contrast agent, proflavine. HRME images were subsequently captured. Histopathological diagnosis was obtained for each sample. Quality-controlled images were used to assemble a training set. After reviewing the training images, 6 otolaryngologists without prior HRME experience reviewed and classi- fied test images. Results: Five samples of inverted papilloma and 2 normal sinonasal mucosa samples were collected. Four representative images from each specimen were used for the 28- image test set. The mean accuracy among all reviewers was 89.9% (95% confidence interval [CI], 84.3% to 94.0%). The sensitivity to correctly identify inverted papilloma was 86.7% (95% CI, 79.2% to 92.2%), and the specificity was 92.9% (95% CI, 89.0% to 100.0%). The Fleiss kappa interrater reliability score was 0.80 (95% CI, 0.70 to 0.89). Conclusion: Inverted papilloma and normal sinonasal mucosa have distinct HRME imaging characteristics. Otolaryngologists can be successfully trained to distinguish between inverted papilloma and normal sinonasal mucosa. HRME is a feasible tool for identification of inverted papilloma. By conducting future in vivo trials, HRME potentially may enable real-time surgicalmargin determination during surgical excision of inverted papilloma. [ABSTRACT FROM AUTHOR]

We implemented a streamlined care pathway for patients undergoing endoscopic transsphenoidal (TSA) pituitary surgery. Select patients are recovered in the postanesthesia care unit and transferred to a step-down unit for intermediate neurologic care (INCU), with clinicians trained to manage cerebrospinal fluid leak, diabetes insipidus (DI), and other complications. We evaluated all TSA surgeries performed at 1 academic medical center from 7th January, 2017 to 30th March, 2020, collecting patient factors, tumor characteristics, cost variables, and outcomes. The INCU pathway was implemented on 7th January 2018. Pathway patients were compared with nonpathway patients across the study period. Outcomes were assessed using multivariate regression, adjusting for patient and surgical characteristics, including intraoperative cerebrospinal fluid leak, postoperative DI, and tumor dimensions. One hundred eighty-seven patients were identified. Seventy-nine were on the INCU pathway. Mean age was 53.5 years. Most patients were male (66%), privately insured (62%), and white (66%). Mean total cost of admission was $27,276. Mean length of stay (LOS) was 3.97 days. Use of the INCU pathway was associated with total cost reduction of $6376.33 (P < 0.001, 95% confidence interval [CI]: $3698.21–$9054.45) and LOS reduction by 1.27 days (P = 0.008, 95% CI: 0.33–2.20). In-hospital costs were reduced across all domains, including $1964.87 in variable direct labor costs (P < 0.001, 95% CI: $1142.08–$2787.64) and $1206.52 in variable direct supply costs (P < 0.001, 95% CI: $762.54–$1650.51). Pathway patients were discharged earlier despite a higher rate of postoperative DI (25% vs. 11%, P = 0.011), with fewer readmissions (0% vs. 6%, P = 0.021). A streamlined care pathway following TSA surgery can reduce in-hospital costs and LOS without compromising patient outcomes. [ABSTRACT FROM AUTHOR]

Background Over the past 20 years, image guidance navigation has been used with increasing frequency as an adjunct during sinus and skull base surgery. These devices commonly utilize surface registration, where varying pressure of the registration probe and loss of contact with the face during the skin tracing process can lead to registration inaccuracies, and the number of registration points incorporated is necessarily limited. The aim of this study was to evaluate the use of novel facial recognition software for image guidance registration. Methods Consecutive adults undergoing endoscopic sinus surgery (ESS) were prospectively studied. Patients underwent image guidance registration via both conventional surface registration and facial recognition software. The accuracy of both registration processes were measured at the head of the middle turbinate (MTH), middle turbinate axilla (MTA), anterior wall of sphenoid sinus (SS), and nasal tip (NT). Results Forty-five patients were included in this investigation. Facial recognition was accurate to within a mean of 0.47 mm at the MTH, 0.33 mm at the MTA, 0.39 mm at the SS, and 0.36 mm at the NT. Facial recognition was more accurate than surface registration at the MTH by an average of 0.43 mm ( p = 0.002), at the MTA by an average of 0.44 mm ( p < 0.001), and at the SS by an average of 0.40 mm ( p < 0.001). The integration of facial recognition software did not adversely affect registration time. Conclusion In this prospective study, automated facial recognition software significantly improved the accuracy of image guidance registration when compared to conventional surface registration.

Introduction: Nasopharyngeal angiofibroma (NA) characteristically affects adolescent men. Although benign, these tumors can cause local destruction and surgical resection is warranted. Objective: We present a case of a 62-year-old man with nasal congestion and epistaxis, found to be a right NA on pathology. We also present a review of the available NA staging systems. Findings: In this case of NA, imaging revealed an aggressive, hypervascular mass in the nasal cavity with involvement of the middle cranial fossa and cavernous sinus. The patient underwent complete endoscopic surgical resection following vascular embolization. Conclusions: Although it is rare, NA should not be disregarded in the elderly population.

Background: Quality improvement (QI) in the management of chronic rhinosinusitis (CRS) is garnering increasing attention. Defining frameworks and metrics to assess the quality of key components in CRS management could assist in reducing unwarranted practice variation and increase high‐quality care. Methods: A panel of the American Rhinologic Society (ARS) QI committee reviewed the literature to determine important presurgical components of CRS care that warrant QI. The evidence was organized into 4 categories: (1) diagnosis, (2) medical management, (3) appropriate patient selection for surgery, and (4) patient‐centered discussion. The combination of these categories was used to develop a framework termed the CRS Appropriate Presurgical Algorithm (CAPA). Results: Prior to offering surgery for CRS, the best available evidence support the following quality metrics: (1) a guideline‐based diagnosis should be confirmed; (2) appropriate medical management, including a minimum of topical corticosteroid therapy and saline irrigations, should have been attempted (assuming patient tolerance); (3) a computed tomography (CT) scan should be obtained (to confirm the presence of sinus inflammation and for surgical planning); and (4) a patient‐centered discussion regarding treatment options for refractory CRS (ie, alternative medical therapies vs surgery vs observation) while focusing on risks and benefits, the need for long‐term medical compliance, and understanding of patient preferences and expectations. Conclusion: Defining metrics that assess key components to CRS care prior to offering surgery has the potential to further improve upon an already successful treatment paradigm, reduce unwarranted practice variation, and to ensure that patients are receiving a similar level of high‐quality care.

Background: In this study we assessed patient outcomes after complete endoscopic sinus surgery (ESS) and aspirin desensitization for patients with aspirin‐exacerbated respiratory disease (AERD). Methods: A retrospective chart review was conducted for patients with aspirin challenge–proven AERD who underwent complete ESS followed by aspirin desensitization. Outcomes assessed included need for revision surgery and quality‐of‐life measures using the 22‐item Sino‐Nasal Outcomes Test (SNOT‐22). Data were collected preoperatively, postoperatively prior to desensitization, and then at intervals post‐desensitization through 30 months after aspirin desensitization. A longitudinal linear mixed‐effects model was used for data analysis. Results: Thirty‐four patients met the inclusion criteria for this study. Thirty‐two patients successfully completed aspirin desensitization and were subsequently followed for 30 months after desensitization. Two patients were unable to complete desensitization. Five patients discontinued aspirin maintenance therapy due to gastrointestinal and respiratory side effects. Within the follow‐up period, there were only 3 (9.4%) revision sinus surgeries. Notably, 1 of these revision cases occurred in a patient who had discontinued aspirin maintenance therapy. After surgical treatment and prior to desensitization patients had significant reductions in SNOT‐22 scores. Our results demonstrate that total SNOT‐22 scores remained statistically unchanged from immediate post‐desensitization throughout the 30‐month follow‐up period. Conclusion: Complete sinus surgery followed by timely aspirin desensitization and maintenance therapy is an effective combination in the long‐term management of sinus disease in patients with AERD.

Background Esthesioneuroblastomas (ENB) are uncommon and data regarding outcomes are often limited to single-institution series. The National Cancer Database (NCDB), which contains outcomes information from treatment centers across the United States, represents an opportunity to evaluate outcomes for rare diseases such as ENB across multiple institutions. Methods The NCDB was queried for location codes corresponding to the nasal cavity and paranasal sinuses and the histology code for ENB. Multivariate analyses were performed to evaluate for contributing factors to overall survival. Results A total of 1225 patients with ENB met the inclusion criteria. The 5-year overall survival was 76.2% (95% confidence interval [CI], 73.4-79.0%). Overall survival was associated with Kadish stage, grade, treatment sequence, margin status, Charlson/Deyo score, age, and gender ( p < 0.05). Multivariate analysis demonstrated that, compared with surgery alone, surgery followed by radiation without chemotherapy had improved all-cause mortality (odds ratio [OR], 0.61; 95% CI, 0.40-0.95). Surgery with chemotherapy alone was associated with increased odds of all-cause mortality (OR, 4.86; 95% CI, 2.31-10.25). Multivariate subanalysis for Kadish stages A and B demonstrated no difference in survival between surgery and surgery followed by radiation, but surgery followed by chemoradiation had worse overall survival (OR, 3.03; 95% CI, 1.07-8.56). For Kadish stage C, surgery followed by radiation had improved overall survival compared with surgery alone (OR, 0.44; 95% CI, 0.24-0.81). Conclusion The most common treatment for ENB is surgery followed by radiation, which is associated with the highest overall survival. The role of adjunctive chemotherapy needs to be re-evaluated in further studies. [ABSTRACT FROM AUTHOR]
