Background: Preoperative review of computed tomography (CT) imaging assists with endoscopic sinus surgery (ESS) planning, where trainees may benefit from a systematic approach. We have previously developed an optimized preoperative checklist for sinus CT imaging using an iterative modified Delphi method.

Objective: In this study, we assess the utility of an optimized preoperative checklist for residents performing ESS.

Health Care Disparities in Transsphenoidal Surgery for Pituitary Tumors: An Experience from Neighboring Urban Public and Private Hospitals.

 Few studies have assessed the role of socioeconomic health care disparities in skull base pathologies. We compared the clinical history and outcomes of pituitary tumors at private and public hospitals to delineate whether health care disparities exist in pituitary tumor surgery.  We reviewed the records of patients who underwent transsphenoidal pituitary tumor resection at NYU Langone Health and Bellevue Hospital.

Discontinuation of Postoperative Prophylactic Antibiotics for Endoscopic Endonasal Skull Base Surgery.

 Postoperative prophylactic antibiotic usage for endoscopic skull base surgery varies based on the institution as evidence-based guidelines are lacking. The purpose of this study is to determine whether discontinuing postoperative prophylactic antibiotics in endoscopic endonasal cases led to a difference in central nervous system (CNS) infections, multi-drug resistant organism (MDRO) infections, or other postoperative infections.  This quality improvement study compared outcomes between a retrospective cohort (from September 2013 to March 2019) and a prospective cohort (April 2019 to June 2019) after adopting a protocol to discontinue prophylactic postoperative antibiotics in patients who underwent endoscopic endonasal approaches (EEAs).

Detection of Cerebrospinal Fluid Leaks Using the Endoscopic Fluorescein Test in the Postoperative Period following Pituitary and Ventral Skull Base Surgery.

 Diagnosis of cerebrospinal fluid (CSF) leaks is sometimes challenging in the postoperative period following pituitary and ventral skull base surgery. Intrathecal fluorescein (ITF) may be useful in this setting.  Retrospective chart review.

The Value of Intraoperative Magnetic Resonance Imaging in Endoscopic Endonasal Resection of Pituitary Adenoma.

 Intraoperative magnetic resonance images (iMRIs) have been variably adopted by some centers to help increase the rate of gross total resection (GTR) of pituitary adenomas. In this comparative study, we report our institution's experience with using iMRIs for endoscopic endonasal approach (EEA) pituitary adenoma resection to better elucidate its role and potential value for pituitary surgery.  All adult patients who underwent EEA for a pituitary adenoma from January 2013 to September 2021 were retrospectively reviewed.

The Cost Effectiveness of Implementation of a Postoperative Endocrinopathy Management Protocol after Resection of Pituitary Adenomas.

 After developing a protocol for evaluating, diagnosing, and treating postoperative endocrinopathy both during the hospitalization and during the immediate discharge period following resection of pituitary adenomas, we sought to assess the impact of this protocol on quality outcomes.  An IRB-exempt, quality improvement initiated, Health Insurance Portability and Accountability Act (HIPAA)-compliant retrospective comparison of a pre-and-post-protocol cohort of all patients undergoing endoscopic endonasal resection of pituitary adenomas at NYU Langone Medical Center from January 2013 to December 2018. Demographic characteristics of the patients and their tumors with their postoperative outcomes were recorded.

Comparing Rates of Postoperative Meningitis After Endoscopic Endonasal Procedures Based on Methicillin-Resistant Staphylococcus aureus/Methicillin-Sensitive Staphylococcus aureus Colonization and Antibiotic Prophylaxis.

Background: Endoscopic endonasal approach (EEA) procedures are inherently contaminated due to direct access through the nasopharyngeal mucosa. The reported rate of postoperative meningitis in EEA procedures is 0.7%-3%.

Development of an optimized preoperative computed tomography imaging checklist for endoscopic sinus surgery utilizing a systematic review of the literature and the modified Delphi method.

Background: Critical review of computed tomography (CT) imaging is essential in preoperative planning for endoscopic sinus surgery. In this study, we used a systematic review and a modified Delphi method to develop a comprehensive checklist that facilitates preoperative review of sinus CT imaging.

Methods: We performed a systematic review of PubMed, Embase, CINAHL, Cochrane, and Web of Science databases to identify existing checklists developed to evaluate sinus CT imaging.

Sinonasal Undifferentiated Carcinoma with Failed Response to Induction Chemotherapy.

Sinonasal undifferentiated carcinoma (SNUC) is a rapidly growing malignancy with a propensity for extensive local invasion. Multimodal therapy, including surgery, radiotherapy, and chemotherapy, is the standard approach to treatment, but the optimal sequence and combination of these modalities are uncertain. Induction chemotherapy is being increasingly utilized based on recent reports that show better outcomes for patients who respond to chemotherapy and the ability to determine further course of treatment.

Sinonasal Glomangiopericytoma with Prolonged Postsurgical Follow-Up.

Sinonasal glomangiopericytoma is a rare vascular tumor of the respiratory epithelium. Treatment consists mainly of surgical resection, though there is no consensus regarding the use of adjuvant therapies or preoperative endovascular embolization. The postsurgical prognosis is favorable, though there is a high risk of delayed recurrence.

Eosinophilic mucin chronic rhinosinusitis with orbital involvement: management strategies based on clinical presentation.

Allergic fungal sinusitis (AFS) and eosinophilic mucin chronic rhinosinusitis (EMCRS) are subtypes of a chronic rhinosinusitis with eosinophilia that have different diagnostic criteria but are phenotypically similar. Ophthalmic complications may be the presenting symptoms. Treatment of ophthalmic complications is typically directed at reducing the inflammatory burden in the sinuses and rarely requires direct surgical intervention.

Postoperative antibiotic use in patients with unilateral purulent chronic rhinosinusitis.

Objectives: To describe our experience with the use of postoperative antibiotics in the management of unilateral chronic rhinosinusitis (CRS) patients with active infection at the time of surgery, and to evaluate the need for routine postoperative antibiotic administration in this population.

Methods: This retrospective chart review analyzed the medical records of all patients who underwent endoscopic sinus surgery for unilateral purulent CRS between November 2013 and September 2019 at a tertiary care center and who were not prescribed routine postoperative antibiotics. Duration of time until normalization of sinus cavities and whether antibiotics were ultimately prescribed for persistent infectious signs and symptoms were recorded.

Meningitis in the Setting of Frontoethmoidal and Temporal Meningoencephaloceles.

This is a patient with multiple meningoencephaloceles which resulted in bacterial meningitis and subsequent status epilepticus. We identify impressive imaging findings demonstrating herniation of the meninges from nasal and bitemporal skull base defects possibly as a result of intracranial hypertension.

Skull Base Aerosol Generating Cases Amidst the COVID-19 Pandemic: An Experience from the Epicenter.

Soon after the World Health Organization declared the severe acute respiratory syndrome coronavirus 2 a global health emergency on January 30, 2020, New York City was plagued by the virus and its health system and economy pushed to their limits. The majority of the limited neurosurgical data in relation to COVID-19 is anecdotal and the higher theoretical risk of transmission of the virus among skull base aerosol generating (SBAG) cases has not been investigated or discussed in a neurosurgical population. We discuss a series of 13 patients who underwent 15 SBAG surgical procedures during the peak of COVID-19 in our hospital system and the protocols use perioperatively for their procedures.

Utilization of Prophylactic Antibiotics After Nasal Packing for Epistaxis.

Background: There have been few investigations examining the benefits, consequences, and patterns of use for prophylactic antibiotics for nasal packing in the emergency department setting. Given the frequency of epistaxis in the emergency department, it is an ideal setting to study the efficacy and utilization patterns of prophylactic antibiotics in nasal packing.

Objective: Our aim was to assess both rates of utilization and evidence of benefit for prophylactic antibiotics in patients with nasal packing for epistaxis.
