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.

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

Gordon, Alex J.; Dastagirzada, Yosef; Schlacter, Jamie; Mehta, Sonal; Agrawal, Nidhi; Golfinos, John G.; Lebowitz, Richard; Pacione, Donato; Lieberman, Seth
Objectives 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. Methods We reviewed the records of patients who underwent transsphenoidal pituitary tumor resection at NYU Langone Health and Bellevue Hospital. Seventy-two consecutive patients were identified from each hospital. The primary outcome was time-to-surgery from initial recommendation. Secondary outcomes included postoperative diabetes insipidus, cerebrospinal fluid (CSF) leak, and gross total resection. Results Of 144 patients, 23 (32%) public hospital patients and 24 (33%) private hospital patients had functional adenomas (p = 0.29). Mean ages for public and private hospital patients were 46.5 and 51.1 years, respectively (p = 0.06). Private hospital patients more often identified as white (p < 0.001), spoke English (p < 0.001), and had private insurance (p < 0.001). The average time-to-surgery for public and private hospital patients were 46.2 and 34.8 days, respectively (p = 0.39). No statistically significant differences were found in symptom duration, tumor size, reoperation, CSF leak, or postoperative length of stay; however, public hospital patients more frequently required emergency surgery (p = 0.03), developed transient diabetes insipidus (p = 0.02), and underwent subtotal resection (p = 0.04). Conclusion Significant socioeconomic differences exist among patients undergoing pituitary surgery at our institution's hospitals. Public hospital patients more often required emergency surgery, developed diabetes insipidus, and underwent subtotal tumor resection. Identifying these differences is an imperative initial step in improving the care of our patients.

Postoperative antibiotic use in patients with unilateral purulent chronic rhinosinusitis

Gordon, Alex; Benedict, Peter; Marcus, Sonya; Kingery, Matthew; Lebowitz, Richard A; Lieberman, Seth M
Objectives/UNASSIGNED: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/UNASSIGNED: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. Patient characteristics and findings were analyzed to determine if any of the evaluated parameters were associated with the need for postoperative antibiotics. Results/UNASSIGNED: = .066). No evaluated variables were associated with antibiotic use on univariate or multivariate analysis. Conclusion/UNASSIGNED:Postoperative antibiotics were not necessary to normalize infected sinus cavities for nearly half of patients with unilateral purulent CRS in this series. Further studies are needed to better delineate which patients would derive benefit from postoperative antibiotics. Level of Evidence/UNASSIGNED:Level IV.

Meningitis in the Setting of Frontoethmoidal and Temporal Meningoencephaloceles

Kumar, Arooshi; Shah, Jugal; Melmed, Kara; Pacione, Donato; Lieberman, Seth; Lewis, Ariane
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.

Utilization of Prophylactic Antibiotics After Nasal Packing for Epistaxis

Hu, Lizbeth; Gordon, Steven A; Swaminathan, Anand; Wu, Tina; Lebowitz, Richard; Lieberman, Seth
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. METHODS:A single-institution retrospective review of 275 cases of anterior nasal packing in an urban emergency department between September 2013 and April 2017 was performed. Chi-square statistical analysis was used to evaluate results. RESULTS:Among 275 cases studied, there were no instances of toxic shock syndrome. Roughly 73% of patients with nonabsorbable packing received prophylactic antibiotics. Only one (1.1%) case of sinusitis was noted among the nonabsorbable packing with prophylaxis group, with no such complication in the nonprophylaxis group. In contrast, 95% of patients with absorbable nasal packing were not given prophylactic antibiotics. Analysis of all cases given prophylactic antibiotics vs. no prophylaxis, regardless of packing type, revealed no statistically significant difference in the development of acute sinusitis (1% vs. 0.56%; p = 0.6793). CONCLUSIONS:There was no observed advantage or disadvantage to using prophylactic antibiotics in anterior nasal packing in the emergency department, regardless of whether patients received absorbable or nonabsorbable packing. However, patients who receive nonabsorbable nasal packing were more likely to receive antibiotic prophylaxis.

Transclival Approach for Resection of a Pontine Cavernous Malformation: 2-Dimensional Operative Video

London, Dennis; Lieberman, Seth; Tanweer, Omar; Pacione, Donato
Cerebral cavernous malformations are common vascular anomalies consisting of a cluster of capillaries without intervening brain tissue.1 A variety of approaches for resection have been undertaken,2 and a handful of case reports have described the endoscopic, endonasal, transclival approach.3 We present a case of a 51-yr-old woman with lupus and hepatitis B-associated cirrhosis who presented with diplopia, dysphagia, and ataxia. She had a left abducens nerve palsy and magnetic resonance imaging (MRI) showed a left pontine cavernous malformation. After a repeat hemorrhage, she consented to surgical resection. The lesion appeared to come to the medial pontine pial surface. Tractography indicated a rightward displacement of the left corticospinal tract. Therefore, an endoscopic, transnasal, transclival approach was chosen. A lumbar drain was placed preoperatively. The clivus and ventral petrous bone were drilled using the vidian canal to help identify the anterior genu of the petrous carotid artery. The clival dura was opened, revealing the abducens nerve exiting the ventral pons. The cavernoma was visible on the surface lateral to the nerve. It was removed using blunt dissection and the remaining cavity inspected. The skull base was reconstructed using an abdominal dermal-fat graft and Alloderm covered by a nasoseptal flap. Postoperatively she had transient swallowing difficulty. The lumbar drain was kept open for 5 d. Cerebrospinal fluid (CSF) leak was ruled out using an intrathecal fluorescein injection. She was discharged home, but presented 2 wk postoperatively with aseptic meningitis, which was treated supportively. Postoperative imaging did not show residual cavernoma.

Spontaneous, Intrasphenoidal Rupture of Ecchordosis Physaliphora with Pneumocephalus Captured During Serial Imaging and Clinical Follow-up: Pathoanatomic Features and Management [Case Report]

Derakhshani, Ahrya; Livingston, Stephanie; William, Christopher; Lieberman, Seth; Young, Matthew; Pacione, Donato; Dehkharghani, Seena
BACKGROUND:Ecchordosis physaliphora (EP) is a congenital, uniformly asymptomatic, hamartomatous lesion of the primitive notochord. Herein we report, to our knowledge, the first credible case report of unprovoked intra-sphenoidal rupture resulting in recurrent pneumocephalus and cerebrospinal fluid (CSF) leak, definitively captured over serial imaging during clinical and radiologic surveillance. CASE DESCRIPTION/METHODS:A 68-year old woman with Marfan syndrome presented to the Emergency Department with the worst headache of life. Imaging demonstrated extensive pneumocephalus and revealed a small, dorsal midline clival lesion consistent with EP and a trans-sphenoidal defect. Remote imaging encounters confirmed typical EP without pneumocephalus or cortical defect, and an uneventful clinical course years preceding presentation. Over the ensuing months during neurosurgical follow-up, the patient reported recurrent headaches, imbalance, and unprovoked clear rhinorrhea. Further imaging demonstrates an apparently enlarging trans-sphenoidal defect which was managed by endoscopic trans-nasal resection and nasoseptal flap. Pathologic evaluation confirmed the diagnosis of EP and chronic dural defect. CONCLUSIONS:This represents, to our knowledge, the first unambiguous example of spontaneous EP rupture and recurrent pneumocephalus captured over serial imaging. The case further underscores rare, but potentially significant complications of EP and highlights management options. BACKGROUND:. Herein we report, to our knowledge, the first documented spontaneous rupture of EP resulting in recurrent pneumocephalus, credibly captured over serial radiologic surveillance. CLINICAL PRESENTATION/METHODS:A 68 year-old woman with history of hypertension, hyperlipidemia, and Marfan syndrome presented to the Emergency Department reporting the "worst headache of her life" after engaging in an interpersonal dispute the evening preceding presentation.

Human papillomavirus and survival of patients with sinonasal squamous cell carcinoma

Oliver, Jamie R; Lieberman, Seth M; Tam, Moses M; Liu, Cheng Z; Li, Zujun; Hu, Kenneth S; Morris, Luc G T; Givi, Babak
BACKGROUND:To the authors' knowledge, the question of whether human papillomavirus (HPV) infection is associated with outcomes in patients with sinonasal squamous cell carcinoma (SNSCC) is not well studied at this time. In the current study, the authors investigated patterns of HPV testing and its association with survival in patients with SNSCC using the National Cancer Data Base. METHODS:The authors selected all SNSCC cases diagnosed between 2010 and 2016. HPV testing practices, clinicodemographic factors, treatments, and survival were analyzed. Multivariable Cox regression and propensity score-matched survival analyses were performed. RESULTS:A total of 6458 SNSCC cases were identified. Of these, only 1523 cases (23.6%) were tested for HPV and included in the current study. The median patient age was 64 years and the majority had advanced stage tumors (overall AJCC stage III-IV, 721 patients; 62.1%). HPV-positive SNSCC comprised 31.5% (447 of 1418 cases) of the final study cohort. Among 15 hospitals that routinely tested nonoropharyngeal SCCs for HPV, the percentage of HPV-positive SNSCCs was smaller (24.6%; P = .04). Patients with HPV-positive SNSCC were younger (aged 60 years vs 65 years; P < .001), with tumors that were more likely to be high grade (55.3% vs 41.7%; P < .001), and attributed to the nasal cavity (62.2% vs 44.0%; P < .001). HPV-positive SNSCC was associated with significantly improved overall survival in multivariable regression analysis (hazard ratio, 0.45; 95% CI, 0.28-0.72 [P = .001]) and propensity score-matched (hazard ratio, 0.61; 95% CI, 0.38-0.96 [P = .03]) analyses controlling for clinicodemographic and treatment factors. CONCLUSIONS:Currently, only a minority of patients with SNSCC are tested for HPV. However, a sizable percentage of SNSCC cases may be HPV related; furthermore, HPV-positive SNSCC is associated with improved overall survival. Routine HPV testing may be warranted in patients with SNSCC.

Role of intraoperative MRI in endoscopic endonasal transsphenoidal pituitary surgery [Meeting Abstract]

Dastagirzada, Y; Benjamin, C G; Bevilacqua, J; Gurewitz, J; Golfinos, J G; Placantonakis, D; Sen, C; Jafar, J; Fatterpekar, G; Lieberman, S; Lebowitz, R; Pacione, D
The transsphenoidal corridor for pituitary adenoma surgery was established as early as 1906 by Schloffer and was subsequently refined by Cushing throughout the early 20thcentury [1]. The use of intraoperative magnetic resonance imaging (iMRI) in endoscopic endonasal transsphenoidal resections, however, is a relatively contemporary addition to the surgical treatment of pituitary tumors. The morbidity of these cases has decreased over the years in light of advances in intraoperative navigation as well as improvements in endoscope dynamics and surgical instruments. Despite such improvements, a substantial number of patients require repeat surgeries or subsequent radiotherapy for residual and/or recurrent disease. This can be largely attributed to cavernous sinus invasion or suprasellar extension, which pose technical challenges to achieving gross total resections (GTRs). The rate of GTR for pituitary tumors cited in the literature varies from 59-88%.[2-3] The advantage of iMRI is that it provides the surgeon with immediate feedback regarding their progress and ability to safely achieve GTR which, in pituitary surgery, is critical for long term cure. Additionally, although there is concern for increased risk of postoperative endocrine dysfunction, Zhibin et al prove that this is not necessarily the case. In their series, 133 patients who underwent iMRI had higher rates of GTR and did not have a significant difference in postoperative hypopituitarism. [4] This study includes a combined retrospective and prospective comparative analysis of 238 patients who underwent transsphenoidal resection of a pituitary tumor from January 2013 until May 2019. All patients were operated on by one of four experienced neurosurgeons and one of three experienced otolaryngologists. There were 203 patients who did not undergo iMRI and 25 patients who did. A 3 tesla MRI magnet was used in all cases. All intraoperative images were read and interpreted by a senior neuroradiologist at our institution. Amongst the two groups, there was no statistically significant difference in patient age (p = 0.488), tumor size (microadenoma versus macroadenoma, p = 0.878), and primary versus recurrent tumor (p = 0.837). The use of iMRI did not yield a decrease in the length of stay (4.84 days in the no iMRI group and 5 in the iMRI group, p = 0.777). There were zero cases of a return to the OR for residual tumor in the intraoperative MRI group versus the non-MRI group. However, this did not reach statistical significance. This study did not yield a statistically significant difference in GTR (p = 0.75), near total resection (NTR, p = 0.167), or subtotal resection (p = 0.083). This is likely secondary to a low sample size and therefore power in the iMRI group. Finally, there was no significant difference in the number of patients requiring postoperative DDAVP (p = 0.099) or hydrocortisone (p = 0.873) after discharge. Preliminary results reveal a potential benefit of iMRI use to assess for residual disease which can be addressed immediately during the initial operation, thus decreasing the need for re-operations. Furthermore, the ability to correlate intraoperative findings with an intraoperative structure may lead to more precise identification and preservation of normal gland, which can possibly decrease the incidence of postoperative endocrine dysfunction
