Trends in Spontaneous Cerebrospinal Fluid Leak Repairs in the United States, 2009-2018.

Background: Rates of spontaneous cerebrospinal fluid leak (sCSF) repairs have increased in recent decades in line with increases in obesity rates.

Objectives: To determine if the national rate of sCSF leak has continued to rise in recent years and to identify associated risk factors utilizing a comprehensive national database comprising most academic medical centers.

Methods: A retrospective review from 2009 to 2018 was performed using the Vizient Clinical Database (CDB) of 105 leading academic medical centers in the United States.

Predictors of Quality-of-Life Improvements Following Global Head and Neck Surgery Trips to Underserved Regions.

Objectives/hypothesis: To conduct longitudinal postoperative follow-up and discern health-related quality-of-life (HR-QoL) changes using a validated questionnaire among patients undergoing head and neck surgeries during a short-term, global surgical trip in a resource-limited setting. To identify clinicodemographic predictors of post-operative HR-QoL improvements in this setting.

Study Design: Retrospective observational study with prospective follow-up.

The Effects of Age and Race on Calvarium, Tegmen, and Zygoma Thickness.

Objective: Temporal bone spontaneous cerebrospinal fluid (sCSF) leaks are characterized by defects in the tegmen along with calvarial thinning without associated thinning of the extracranial zygoma. The authors sought to determine the effect of age and race on calvarial, tegmen, and zygoma thickness.

Study Design: Retrospective cohort study.

Recurrent Primary Intrasellar Paraganglioma.

We describe a case of an 81-year-old male presenting with bitemporal visual field defects and blurry vision in the right eye. The patient was found to have a recurrent primary paraganglioma in the sellar and suprasellar region requiring a repeat transsphenoidal endoscopic resection. Immunohistochemical examination confirmed paraganglioma with the classic zellballen appearance which stained positive for chromogranin, synaptophysin, and S-100 in the periphery.

Manifestations of Pediatric Extranodal Rosai Dorfman Disease in the head and neck.

Objectives: To systematically evaluate the clinico-diagnostic profile and management outcomes of otorhinolaryngologic manifestations of Extranodal Rosai-Dorfman Disease (ENRDD) in the pediatric population.

Methods: The search terms Rosai Dorfman Disease and Sinus Histiocytosis were used to query PubMed, Ovid/Medline, and Scopus databases from inception through September 30, 2018. Studies were systematically reviewed in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol.

Association of Intracranial Hypertension With Calvarial and Skull Base Thinning.

Objective: Determine if patients with increased opening pressure (OP) on lumbar puncture (LP) have thinner calvaria and skull bases.

Study Design: Retrospective cohort study.

Setting: Tertiary referral center.
