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: Endoscopic endonasal repair of cerebrospinal fluid (CSF) rhinorrhea secondary to idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri or benign intracranial hypertension, has varying success rates, from 25-87%, with minimal morbidity. However, often these series have a relatively short-term follow-up. Given the pathophysiology of IIH, long-term follow-up is necessary to identify true CSF leak recurrence rates. Our investigation aimed to evaluate long-term outcomes in endoscopically repaired CSF leaks. Methods: A retrospective chart review of all the patients with CSF rhinorrhea due to IIH who met inclusion criteria between 1996 and 2009. Outcome measures included the following: demographics, intracranial pressure, location of skull base defect, presence of encephalocele and/or meningoencephalocele, surgical repair technique, treatment with acetazolamide, whether a ventriculoperitoneal shunt was inserted, location of recurrence, history of meningitis or previous sinus surgery, and duration of follow-up. Results: Thirty-two patients with a total of 44 skull base defects were reviewed over a mean follow-up of 10.2 years. The mean body mass index and intracranial pressure were 36.8 kg/m
2 and 27.7 cm H2 O, respectively. Seven patients (18%) required revision surgery at the same site or a distant site. We found no statistical significance that identified the recurrence risk in the outcome measurements most likely due to our small failure rate. However, early recurrences were noted to recur at the same repair site, whereas late recurrences were noted to recur at a distant site along the skull base. Conclusion: IIH is an increasingly recognized entity treated by otorhinolaryngologists. We present the first long-term IIH CSF leak repair series. Long-term follow-up is necessary because delayed CSF leaks occur in this population. [ABSTRACT FROM AUTHOR]- Published

Background: Management of sinonasal malignancy (SNM) often includes surgical resection as part of the multimodality treatment. Treatment‐related surgical morbidity can occur, yet risk factors associated with complications in this population have not been sufficiently investigated. Methods: Adult patients with histologically confirmed SNM whose primary treatment included surgical resection were prospectively enrolled into an observational, multi‐institutional cohort study from 2015 to 2020. Sociodemographic, disease, and treatment data were collected. Complications assessed included cerebrospinal fluid leak, orbital injury, intracranial injury, diplopia, meningitis, osteoradionecrosis, hospitalization for neutropenia, and subsequent chronic rhinosinusitis. The surgical approach was categorized as endoscopic resection (ER) or open/combined resection (O/CR). Associations between factors and complications were analyzed using Student's t test, Fisher's exact test, and logistic regression modeling. Results: Overall, 142 patients met the inclusion criteria. Twenty‐three subjects had at least 1 complication (16.2%). On unadjusted analysis, adjuvant radiation therapy was associated with developing a complication (91.3% vs 65.5%, p = 0.013). Compared with the ER group (n = 98), the O/CR group (n = 44) had a greater percentage of higher T‐stage lesions (p = 0.004) and more frequently received adjuvant radiation (84.1% vs 64.4%, p = 0.017) and chemotherapy (50.0% vs 30.6%, p = 0.038). Complication rates were similar between the ER and O/CR groups without controlling for other factors. Regression analysis that retained certain factors showed O/CR was associated with increased odds of experiencing a complication (odds ratio, 3.34; 95% confidence interval, 1.06‐11.19). Conclusions: Prospective, multicenter evaluation of SNM treatment outcomes is feasible. Undergoing O/CR was associated with increased odds of developing a complication after accounting for radiation therapy. Further studies are warranted to build upon these findings.

Background: Postoperative nausea and vomiting (PONV) are adverse effects after surgery, which may increase the risk of complications. Aprepitant is a neurokinin‐1 receptor blocker and has been shown to reduce chemotherapy‐related nausea and vomiting and PONV. However, its role in endoscopic skull base surgery remains unclear. The purpose of this study was to evaluate the effect of aprepitant in reducing PONV in endoscopic transsphenoidal (TSA) pituitary surgery. Methods: A retrospective chart review between July 2021 and January 2023 of 127 consecutive patients who underwent TSA was performed at a tertiary academic institution. Patients were divided into 2 groups based on preoperative aprepitant use. Two groups were matched based on known risk factors of PONV (age, sex, nonsmoking, and history of PONV). The primary outcome was the incidence of PONV. Secondary outcome measures included the number of anti‐emetic use, length of stay, and postoperative cererebrospinal fluid (CSF) leak. Results: After matching, 48 patients were included in each group. The aprepitant group demonstrated a significantly lower incidence of vomiting than the non‐aprepitant group (2.1% vs 22.9%, p = 0.002). The number of nausea episodes and anti‐emetic use decreased with aprepitant use (p < 0.05). There was no difference in the incidence of nausea, length of stay, or postoperative CSF leak. Multivariate analysis demonstrated that aprepitant decreased the incidence of postoperative vomiting with odds ratio of 0.107. Conclusion: Aprepitant may serve as a useful preoperative treatment to reduce PONV in patients undergoing TSA. Further studies are needed to evaluate its impact in other arenas of endoscopic skull base surgery. [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: Craniopharyngiomas have traditionally been treated via open transcranial approaches. More recent, endoscopic endonasal approaches have been increasingly used; however, there has been limited evaluation of long‐term outcomes for this approach. Methods: A retrospective review was performed to analyze patients with pediatric craniopharyngioma undergoing endonasal endoscopic resection from 2012 to 2020. Demographic information, clinicopathologic factors, and outcomes including follow‐up and recurrences were analyzed. Results: All 42 patients, with a mean age of 8.0 years, were included. The median follow‐up time was 49 months. Mean tumor diameter was 3.6 cm. All of the tumors had sellar and suprasellar components. The most common presenting symptoms were headaches (64.3%), visual changes (59.5%), and nausea/vomiting (38.1%). Most patients (73.3%) had resolution of their presenting symptoms by their first postoperative visit. Vision improved or remained normal in 69.0% of patients. Postoperatively, incidence of panhypopituitarism or diabetes insipidus developed in 89.7% and 77.8% of patients, respectively. The postoperative cerebrospinal fluid leak rate was 7.1%. The recurrence rate was 9.5%. Conclusion: Endoscopic endonasal resection for pediatric craniopharyngiomas can achieve high rates of resection with low rates of disease recurrence when compared with the outcomes of open transcranial resection reported in the literature. However, hypothalamic‐pituitary dysfunction remains a significant postoperative morbidity in both approaches. [ABSTRACT FROM AUTHOR]

There was no significant difference in postoperative CSF leak rates between pediatric and adult groups, underscoring EEA with NSF repair as a successful and safe technique in the surgical resection of pediatric anterior skull base tumors. One recent study examined NSF skull base reconstruction in a cohort of 12 post-EEA pediatric patients.9 Complications included one CSF leak, with a leak rate of 8.33%. [Extracted from the article]
