Dastagirzada, Yosef; Benjamin, Carolina; Bevilacqua, Julia; Gurewitz, Jason; Sen, Chandra; Golfinos, John G.; Placantonakis, Dimitris; Jafar, Jafar J.; Lieberman, Seth; Lebowitz, Rich; Lewis, Ariane; Pacione, Donato
Background 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. Methods 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). Our primary end points of the study included the presence of postoperative CNS infection, Clostridium difficile (C. diff), and MDRO infections. Results A total of 388 patients were analyzed, 313 in the pre-protocol group and 75 in the post-protocol group. There were similar rates of intraoperative cerebrospinal fluid leak (56.9 vs. 61.3%, p = 0.946). There was a statistically significant decrease in the proportion of patients receiving IV antibiotics during their postoperative course (p = 0.001) and those discharged on antibiotics (p = 0.001). There was no significant increase in the rate of CNS infections in the post-protocol group despite the discontinuation of postoperative antibiotics (3.5 vs. 2.7%, p = 0.714). There was no statistically significant difference in postoperative C. diff (0 vs. 0%, p = 0.488) or development of MDRO infections (0.3 vs 0%, p = 0.624). Conclusion Discontinuation of postoperative antibiotics after EEA at our institution did not change the frequency of CNS infections. It appears that discontinuation of antibiotics after EEA is safe.

Leong, Stephen; Yang, Nathan; Ray, Amrita; Akbar, Nadeem; Colley, Patrick M; Signore, Anthony Del; Eloy, Jean Anderson; Govindaraj, Satish; Gudis, David A; Helman, Samuel; Hsueh, Wayne; Iloreta, Alfred-Marc; Kacker, Ashutosh; Lieberman, Seth; Pearlman, Aaron N; Schaberg, Madeleine R; Tabaee, Abtin; Overdevest, Jonathan B
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 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. An inclusive list of items from these checklists was compiled and modified Delphi methodology was used to assign ranked priority. The Delphi process involved 14 rhinologists and had 3 phases: an initial survey with Likert priority (scale of 1-9), and two rounds of live discussions followed by survey to confirm consensus. RESULTS:Ninety-seven possible checklist items were identified from systematic review and panelist input. On initial survey, 63 items reached a consensus score of 7+ and 13 items had near consensus scores between 6-7; 2 of these 13 borderline items were retained after subsequent panelist discussion. The resulting items were consolidated into an 11-item disease checklist and a 24-item anatomical checklist; the anatomical checklist was further divided into 6 subsections: nasal cavity; maxillary; ethmoid; sphenoid; frontal; skull base and orbit. Additionally, panelists identified 6 core aspects of patient history to consider prior to surgery. CONCLUSIONS:After establishing content validity through a systematic literature review and modified Delphi method, we developed a comprehensive checklist for preoperative sinus CT imaging review; implementation and evaluation of validity among trainees will suggest overall utility.

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

Benedict, Peter A.; Connors, Joseph R.; Timen, Micah R.; Bhatt, Nupur; Lebowitz, Richard A.; Pacione, Donato R.; Lieberman, Seth M.
Objective 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. Design Retrospective chart review. Setting Tertiary care center. Methods and Participants All patients who underwent pituitary and ventral skull base surgery performed by a single rhinologist between January 2017 and March 2020 were included. There were 103 patients identified. Eighteen patients received 20 ITF injections due to clinical suspicion for CSF leak during the postoperative period without florid CSF rhinorrhea on clinical exam. Computed tomography scans with new or increasing intracranial air and intraoperative findings were used to confirm CSF leaks. Clinical courses were reviewed for at least 6 months after initial concern for leak as the final determinate of CSF leak. Main Outcome Measures Specificity and safety of ITF. Results Eleven (61%) ITF patients were female and 7 (39%) were male. Average patient age was 52.50 ± 11.89. There were six patients with confirmed postoperative CSF leaks, 3 of whom had evaluations with ITF. ITF use resulted in 2 true positives, 1 false negative, 17 true negatives, and 0 false positives. ITF sensitivity was 67%, specificity was 100%, and positive and negative predictive values were 100 and 94.4%, respectively. There were no adverse effects from ITF use. Conclusions Existing modalities for detecting postoperative CSF leaks suffer from suboptimal sensitivity and specificity, delayed result reporting, or limited availability. ITF represents a specific and safe test with potential utility in the postoperative setting.

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

Orillac, Cordelia; Patel, Aneek; Dastagirzada, Yosef; Benjamin, Carolina; Lieberman, Seth; Lebowitz, Richard; Golfinos, John G; Pacione, Donato
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%. A variety of methods exist to minimize the risk of meningitis with antibiotic prophylaxis, although their value is not completely understood. This study investigated whether there is a difference in rates of postoperative meningitis based on Staphylococcus aureus colonization and use of preoperative antibiotic prophylaxis. METHODS:All adult patients who underwent EEA resection at our institution from 2013 to 2021 were retrospectively reviewed. Patients with preoperative cerebrospinal fluid infections were excluded. Data including recent preoperative infections, preoperative colonization status, antibiotic administration, and postoperative outcomes were recorded for each patient. RESULTS:Of 483 patients identified (mean age, 51 years; range, 18-90 years; 274 [56.7%] female), 80 (16.6%) had a positive preoperative methicillin-resistant Staphylococcus aureus (MRSA)/methicillin-sensitive Staphylococcus aureus (MSSA) screening swab. Twenty-one (26.3%) colonized patients were treated with preoperative decolonizing antibiotics. Within 30 days of surgery, 13 (2.7%) patients developed culture-positive meningitis. There was no significant difference in meningitis rates based on MRSA/MSSA colonization status. Among colonized patients, there was no significant difference in rates of MRSA/MSSA meningitis based on preoperative antibiotic decolonization. CONCLUSIONS:Postoperative rates of meningitis after EEA surgery were not significantly changed based on MRSA/MSSA colonization status of the patient or preoperative decolonization. The utility of preoperative testing of MRSA/MSSA status and antibiotics for decolonization to prevent postoperative meningitis should be further investigated.

Sinonasal Glomangiopericytoma with Prolonged Postsurgical Follow-Up

Gordon, Alex J; Papazian, Michael R; Chow, Michael; Patel, Aneek; Placantonakis, Dimitris G; Lieberman, Seth; Givi, Babak
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. Here, we present the case of a patient who underwent endoscopic resection of a sinonasal glomangiopericytoma and a review of the literature.

Sinonasal Undifferentiated Carcinoma with Failed Response to Induction Chemotherapy

Papazian, Michael R; Gordon, Alex J; Chow, Michael; Patel, Aneek; Pacione, Donato; Lieberman, Seth; Givi, Babak
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. We present a unique case of a patient with locally advanced SNUC that did not respond to induction chemotherapy and a review of the available literature relating to the management of this rare malignancy.

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

Dastagirzada, Yosef; Klauberg, Olga; Sheerin, Kathleen; Lieberman, Seth; Lebowitz, Richard; McMenomey, Sean; Sen, Chandranath; Roland, J Thomas; Golfinos, John G; Pacione, Donato
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. Our data support that with proper preoperative testing, a well-delineated surgical algorithm, and appropriate personal protective equipment, emergent/urgent cases can be done safely in hospitals that are currently experiencing high volumes of COVID-19 cases as we did in March to May of 2020.
