Objective: To determine the in-hospital cost implications of an endoscopic expanded endonasal approach (EEEA) for meningioma resection relative to the open transcranial approach. Methods: All anterior skull base meningioma surgeries performed over a period from January 1st, 2015 to October 31th, 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 R software. All cost data were converted into August 2021-equivalent dollar amounts using the United States Bureau of Labor Statistics consumer price index. Results: Thirty-five patients met study criteria, including 27 patients undergoing an open transcranial approach and 8 undergoing an EEEA. Average length of stay for patients undergoing an open approach was 9.3 days compared to 5.6 within the EEEA group (P =.126). The average total in-hospital cost of patient undergoing an EEEA was $35417.1 compared to $46406.9 among patients undergoing an open transcranial approach (P =.168). On univariate analysis, the cost of an open transcranial approach relative to the EEEA was $10989.8 (P =.411). Conclusions: The open transcranial approach remained the dominant surgical approach to anterior skull base meningiomas over our study time period. However, despite limited patient numbers the EEEA was associated with decreased total in-hospital costs. [ABSTRACT FROM AUTHOR]

Objectives: Myoepithelial carcinoma (MECA) is a rare salivary gland tumor that can occur in the sinonasal cavity with poor outcomes. There are limited data on sinonasal outcomes to guide management. We sought to use the National Cancer Database (NCDB) to better define treatment outcomes in MECA. Methods: We conducted a retrospective analysis of the NCDB from 2004 to 2016 for patients with MECA of the sinonasal cavity. Patient demographic, treatment, and survival information were extracted from the database. Unadjusted Kaplan–Meier estimates, log-rank tests, and a multivariable Cox proportional hazard model were used to assess overall survival (OS). Results: A total of 38 patients were included. The average age was 60.7 ± 18.2 years and male patients represented 47.4% of the cohort. Most patients were White (n = 26, 68.4%) and the majority of patients had either private insurance (n = 20, 52.6%) or Medicare (n = 15, 39.5%). The primary site of most tumors was nasal cavity (n = 19, 50%), followed by maxillary sinus (n = 16, 42.1%). Most tumors were >4 cm (n = 17, 44.7%). The 1-, 5-, and 10-year OS was 89.7% (95% confidence interval [CI]: 80.7%−99.8%), 63.6% (95% CI: 49.4%−82%), and 46.4% (95% CI: 31%−69.5%), respectively. The median survival for the overall cohort was 85.8 months. Medicare insurance was associated with a decreased OS (hazard ratio [HR]: 8.2; 95% CI: 2.88−23.4, P <.001). Patients who underwent surgery had a significant survival benefit (HR: 0.04, 95% CI: 0.01−0.21, P <.001). Discussion: MECA of the sinonasal cavity is a rare tumor with poorly understood behavior. Data from the NCDB suggests that it is a relatively aggressive tumor with surgical management associated with better outcomes. This analysis is limited by the small sample size and further research into optimal treatment regimens is needed. [ABSTRACT FROM AUTHOR]

Background: Orbital, intracranial, and osseous extra-sinus complications can arise from bacterial or fungal sinusitis. Odontogenic sinusitis (ODS) can cause extra-sinus complications, but its prevalence remains poorly characterized. Objective: To determine the frequency of ODS as a cause of operative extra-sinus infectious complications and describe clinical features of all complicated sinusitis cases. Methods: A multi-institutional retrospective review was performed on all operative sinusitis-related extra-sinus complications from 2011 to 2020. ODS was diagnosed by sinus computed tomography (CT) and dental evaluations when available. Demographics, complication types, sinusitis etiologies, and various clinical features were analyzed. Results: Forty-five patients were included (mean age 55.5 years, 56% male). Of the extra-sinus complications, 40% were orbital only, 22% intracranial only, 13% osseous only, and 25% involved combined complications. The 2 most common causes of extra-sinus complications were ODS (40%) and mucopyocele (27%). When invasive fungal etiologies were excluded, and only unilateral maxillary opacification on CT was considered, nearly 60% of extra-sinus complications were due to ODS. Unilateral maxillary sinus opacification on CT was present in 100% of complicated ODS compared to 44% of nonodontogenic cases, and oral anaerobes were only identified in ODS cases. No complicated ODS patients underwent dental interventions during hospitalization. Conclusion: ODS was the most common cause of operative extra-sinus infectious complications. Clinicians should consider ODS high on the differential diagnosis of all patients presenting with complicated sinusitis, especially when sinusitis is unilateral and invasive fungal infection is not suspected.

Background: Acinic cell carcinoma (ACC) is a salivary gland malignancy that rarely can involve the sinonasal cavity. There are limited outcomes data available to guide management. Objective: We sought to use the National Cancer Database (NCDB) to characterize treatment outcomes in sinonasal ACC. Methods: A retrospective analysis of the NCDB from 2004 to 2016 for patients with ACC involving the sinonasal cavity was conducted. Demographic, treatment, and survival information were obtained. Unadjusted Kaplan-Meier estimates, log-rank tests, and a multivariable Cox proportional hazard model were used to assess overall survival (OS). Results: A total of 28 patients were included in the analysis with an average age of 58.6 ± 15.5 years. Half the patients (n = 14, 50%) were male, mostly white (n = 23, 82.1%), and with private insurance (n = 16, 57.1%). The nasal cavity was the most common subsite (n = 18, 64.3%), followed by the maxillary sinus (n = 5, 17.9%). Most patient received surgery alone (n = 17, 60.7%), with the remaining patients undergoing surgery followed by radiation (n = 8, 28.6%), radiation alone (n = 1, 3.6%), and no treatment (n = 2, 7.1%). The 1-, 5-, and 10-year survival in this cohort was 100% (95% CI: 100%–100%), 84.3% (95% CI: 71.2%–99.7%), and 72.2% (95% CI: 55%–94.8%), respectively. On multivariate analysis, older age was associated with worse OS (hazard ratio (HR): 1.27; 95% CI: 1.11–1.46, P <.001). Disease of the sphenoid sinus correlated with worse survival (HR: 198, 95% CI: 10.4–3,739, P <.001) and large tumor size was associated with worse OS on log-rank test, but not on multivariate analysis. Conclusion: Sinonasal ACC is a rare entity with relatively good long-term outcomes. Older age and primary disease of the sphenoid sinus are associated with worse outcomes. Most patients are treated with surgical resection. Future research is needed to assess the optimal timing and indications for radiation therapy. [ABSTRACT FROM AUTHOR]

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: Aspirin-exacerbated respiratory disease (AERD) is optimally managed by endoscopic sinus surgery (ESS) followed by aspirin therapy after desensitization (ATAD). Most AERD quality of life (QOL) studies use the 22-item Sinonasal Outcomes Test (SNOT-22), which focuses predominantly on sinonasal outcomes. Objective: This study seeks to assess QOL outcomes in AERD patients after ESS and ATAD via the 12-item Short Form Survey (SF-12), a well-validated QOL measure for general health status of chronic conditions. Methods: Retrospective review of 112 AERD patients who underwent ESS followed by ATAD at our institution between 2016 and 2019. SF-12 was collected preoperatively, postoperatively/pre-AD, and serially post-AD (1–3, 4–6, 7–12, and >12 months). Optum® PRO CoRE software was used to compare data to national norms. ANOVA was performed comparing physical component summary (PCS), mental component summary (MCS) and eight health domains (physical functioning, role physical, general health, bodily pain, vitality, social functioning, role emotional, and mental health). Results: AERD patients showed improvement in PCS scores across all timepoints after ESS and ATAD (p = 0.004). When stratified by gender, women demonstrated an improvement in PCS scores (p = 0.004). Within the domains, there were significant improvements in social functioning (SF), role physical (RP), and bodily pain (BP) at all timepoints (SF: p = 0.006; RP: p = 0.005; BP: p < 0.001). Conclusions: AERD patients undergoing ESS and ATAD show improvement in physical QOL and 3 of the 8 health domains as measured by the SF-12. Future studies can use the SF-12 to study the impact of AERD treatment versus other chronic diseases and health demographics. [ABSTRACT FROM AUTHOR]
