Objective: To determine the in-hospital cost implications of an expanded endoscopic endonasal approach (EEEA) for craniopharyngioma resection relative to the traditional open transcranial approach., Methods: All craniopharyngioma surgeries performed at a single institution over a period from January 1st 2001 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 regression analysis was performed using R software., Results: Thirty-six patients met study criteria, including 22 undergoing an open approach and 14 undergoing an EEEA. There was a significantly longer average length of stay among patients undergoing open resection (21.5 vs. 10.6 days, p = 0.024). The average total in-hospital cost of a patient undergoing an EEEA was $58979.3 compared to $89142.3 for an open approach (p = 0.127). On univariate regression analysis, the total in-hospital cost for a patient undergoing an open approach relative to an EEEA was $30163.0 (p = 0.127). The open approach was exclusively performed from study onset until April 2010 (16 patients). From April 2010 to August 2013, 6 open approaches and 5 EEEA were performed. The EEEA has been exclusively performed from August 2013 until the conclusion of our study period (9 patients)., Conclusions: There has been a shift toward surgical resection of craniopharyngioma via an EEEA approach for amenable tumors. Our study demonstrates that the EEEA has become the preferred surgical approach at our institution, and shows that the EEEA is associated with shorter postoperative length of stay and lower total in-hospital cost.

Objective: Surgical resection of skull base tumors in children is increasingly accomplished through an expanded endonasal approach (EEA). We aim to evaluate the potential effect of the EEA on midfacial growth as a result of iatrogenic damage to nasal growth zones., Methods: We performed a retrospective review of children undergoing craniopharyngioma resection via an open transcranial or EEA. Pre- and postoperative magnetic resonance imaging was evaluated for growth in four midfacial measurements based on established cephalometric landmarks: anterior midface height, posterior midface height, palatal length, and sella-nasion distance. Statistical analysis was conducted using a mixed-effects linear regression model., Results: Twenty-two patients underwent an EEA (n = 12) or open transcranial approach (n = 10) for tumor resection with 3 years of imaging follow-up. There was no difference in midfacial growth between groups for each measurement. Compared to the open group, patients undergoing EEA demonstrated relative anterior midface height growth of -0.42 mm (P = 0.880), posterior midface height growth of -0.44 mm (P = 0.839), palatal length growth of 0.35 mm (P = 0.894), and sella-nasion distance growth of -2.16 (P = 0.365)., Conclusion: We found no difference in midfacial growth measurements between patients undergoing craniopharyngioma resection via an EEA and the open transcranial route after 3 years of imaging follow-up. Preliminary results on midfacial growth demonstrate that the EEA is a safe alternative to traditional transcranial approaches for the pediatric population. Further investigation with larger sample size and longer duration of follow-up is warranted to more thoroughly investigate the long-term implications of the EEA to the skull base., Level of Evidence: 3 Laryngoscope, 130:338-342, 2020., (© 2019 The American Laryngological, Rhinological and Otological Society, Inc.)

Objectives/hypothesis: Currently, due to the rarity of pathology, there are limited data surrounding outcomes of pediatric skull base surgery. Traditionally, surgeons have proceeded with caution when electing endonasal endoscopic transsellar/transplanum approaches to the skull base in pediatric patients due to poor sphenoid pneumatization. In this study, we review outcomes of endoscopic pediatric skull base surgery based on sphenoid pneumatization patterns., Study Design: Retrospective chart review., Methods: A review of all cases of pediatric (age < 18 years) craniopharyngioma managed via an endoscopic endonasal approach at a tertiary academic medical center., Results: A total of 27 patients were included in the analysis. The median age was 8 years. Nineteen (70%) patients were male. Presellar, sellar/postsellar, and conchal sphenoid pneumatizations were found in 6, 11, and 10 patients, respectively. There was no significant association between sphenoid pneumatization pattern and extent of resection (gross vs. subtotal, P = .414), postoperative cerebrospinal fluid (CSF) leak (P = .450), intraoperative estimated blood loss (P = .098), total operative time (P = .540), and length of stay (P = .336). On multivariate analysis, after accounting for age, sex, preoperative cranial nerve involvement, and cavernous sinus invasion, there remained no significant association between sphenoid pneumatization pattern and extent of resection (P = .999) and postoperative CSF leak (P = .959)., Conclusions: Sphenoid pneumatization pattern does not appear to affect outcomes in endoscopic skull base surgery in the pediatric population. Importantly, lack of sphenoid pneumatization does not impede gross total resection or increase complications. Thorough knowledge of the anatomy during the endoscopic approach is critical to optimize outcomes., Level of Evidence: 4 Laryngoscope, 129:832-836, 2019., (© 2018 The American Laryngological, Rhinological and Otological Society, Inc.)
