OBJECTIVE There is a paucity of literature regarding the learning curve associated with performing endoscopic endonasal cranial base surgery. The purpose of this study was to determine to what extent a learning curve might exist for endoscopic endonasal resection in cases of craniopharyngiomas. METHODS A retrospective review was performed for all endoscopic endonasal craniopharyngioma resections performed at Thomas Jefferson University from 2005 to 2015. To assess for a learning curve effect, patients were divided into an early cohort (2005-2009, n = 20) and a late cohort (2010-2015, n = 23)...

INTRODUCTION: With the advent of skull base endoscopy, tuberculum sellae meningiomas (TSMs) are currently operated both from the traditional transcranial (TC) route as well as the extended endonasal endoscopic trasnssphenoidal approach (EETS). The aim of this study was to conduct a systematic review of TSMs excised via the TC route in the modern era when the EETS excision is gaining popularity. EVIDENCE ACQUISITION: We performed a systematic review in the medical literature following the PRISMA guidelines...

REVIEW
Mahati Reddy, Kristen Baugnon
As the obesity epidemic grows in the United States, rhinorrhea and otorrhea from spontaneous cerebrospinal fluid (CSF) leaks secondary to untreated idiopathic intracranial hypertension are increasing in prevalence. CSF rhinorrhea and otorrhea should also be carefully evaluated in posttraumatic and postsurgical settings, because untreated CSF leaks often have serious consequences. The work-up, diagnosis, and characterization of a CSF leak can be complex, often requiring a multimodality approach to optimize surgical planning...

Study Design Retrospective chart review. Objective Postoperative cerebrospinal fluid (CSF) leak is a known complication of intraoperative durotomy. Intraoperative placement of subfascial epidural drains following primary dural repair has been proposed as a potential management strategy to prevent formation of CSF cutaneous fistula and symptomatic pseudomeningocele. Here we describe our experience with subfascial drain after intentional durotomy. Methods Medical records of patients who underwent placement of subfascial epidural drains during spinal procedures with intentional intraoperative durotomies over a 4-year period at two institutions were retrospectively reviewed...

BACKGROUND: Binostril endoscopic transsphenoidal approach (BETA) provides sufficient manipulation space and wide endoscopic vision, although it increases the trauma of nose. Mononostril endoscopic transsphenoidal approach (META) has minimal trauma of nose, at the expense of space within the operation. We describe a one-and-a-half nostril endoscopic transsphenoidal approach (OETA) that combines the advantages of BETA and META. METHODS: We introduced OETA for pituitary adenomas with a detailed technical description...

BACKGROUND/AIMS: Since the initial use in 1981 by Wigand, different endoscopic endonasal surgery techniques have been proposed to close ventral skull base defects, all of which include multilayer closure involving vascularized mucoseptal flaps, autologous grafts, and synthetic materials. These methods are used individually or in combination, as required by the operative condition. METHODS: In this study we aimed to describe our endoscopic technique using inlay-outlay fascia lata and autologous fat with fibrin sealant to close spontaneous and traumatic cerebrospinal fluid (CSF) rhinorrhea...

HYPOTHESIS: Endoscopically assisted packing of the Eustachian tube (ET) will improve visualization of the protympanic space compared with standard techniques with the microscope. BACKGROUND: Postoperative cerebrospinal fluid (CSF) leakage after translabyrinthine tumor resection remains a problem. Current techniques of packing the ET are limited by inadequate visualization. The objective of this study is to demonstrate the feasibility and usefulness of transmastoid endoscopic-assisted ET packing during translabyrinthine tumor resection...

BACKGROUND: Meningocele is defined as a protrusion of the meninges through an opening in the skull or spinal column, forming a bulge or sac filled with cerebrospinal fluid. A pseudomeningocele is defined as a cerebrospinal fluid (CSF) collection formed due to escape of CSF through a dural defect with trapping of CSF into the surrounding soft tissues. We herby report rare occurrence of a large (pseudo)meningocele in a young patient with congenital skull base defect presenting as upper lateral neck swelling...

OBJECTIVE: Cerebrospinal fluid (CSF) leak is a well-known complication of skull or sinus surgery. Radionuclide cisternography has high sensitivity for detection of CSF leak, commonly performed in conjunction with radioactivity assay of nasal pledgets. Our objective was to highlight the usefulness of single photon emission tomography/computed tomography (SPET/CT) in radionuclide cisternography by presenting a case of a 41 years old man with right sided rhinorrhea following craniotomies and sinus surgery, who was subjected to radioactivity assay of nasal pledgets and radionuclide cisternography for suspected CSF leak...

BACKGROUND: Severe localised ossification of the posterior longitudinal ligament (OPLL) should be directly removed by anterior approach, but the exposure during anterior cervical diskectomy and fusion (ACDF) is restricted and may increase the risk of a cerebrospinal fluid (CSF) leak. Corpectomy is facilitated to extirpate the ossification, but it is relatively more invasive. The purpose of this study was to investigate the feasibility and clinical outcome of enlarged ACDF in treating severe localised OPLL...

INTRODUCTION: Liquorrhea is a condition characterized by cerebrospinal fluid (CSF) leakage from the cranial cavity due to injury to the integrity of the dura mater (DM) and bone structures of the skull base. Surgery for posterior cranial fossa (PCF) lesions distinguishes wound CSF leakage when CSF leaks from a surgical wound as well as basal CSF leakage (nasal liquorrhea and, less often, otoliquorrhea). The main cause of basal CSF leakage is injury (including surgical injury) resulting in a defect in the DM and bone structures (cells of the mastoid process in the case of a suboccipital retrosigmoid approach)...

OBJECTIVE Regrowth of the lesion after surgical removal of pituitary adenomas is uncommon unless subtotal resection was originally achieved in the first surgery. Treatment for recurrent tumor can involve surgery or radiotherapy. Locations of residual tumor may vary based on the original approach. The authors evaluated the specific sites of residual or recurrent tumor after different transsphenoidal approaches and describe the surgical outcome of endoscopic endonasal transsphenoidal reoperation. METHODS The authors analyzed a prospectively collected database of a consecutive series of patients who had undergone endoscopic endonasal surgeries for residual or recurrent pituitary adenomas after an original transsphenoidal microscopic or endoscopic surgery...

OBJECTIVE: To determine if cranioplasty techniques following translabyrinthine approaches to the cerebellopontine angle are cost-effective. STUDY DESIGN: Retrospective case series. PATIENTS: One hundred eighty patients with available financial data who underwent translabyrinthine approaches at a single academic referral center between 2005 and 2015. INTERVENTION: Cranioplasty with a dural substitute, layered fat graft, and a resorbable mesh plate secured with screws Main Outcome Measures: billing data was obtained for each patient's hospital course for translabyrinthine approaches and postoperative cerebrospinal fluid (CSF) leaks...

OBJECTIVE The authors' goals in this study were to describe a series of dog attacks on children that required neurosurgical consultation and to better understand the pattern of injuries inflicted, the circumstances that place children at risk for attack, and the dog breeds involved. In addition, the authors review the surgical and medical management of these patients. METHODS The authors performed a retrospective review of all children requiring neurosurgical consultation for dog bite at a regional Level 1 pediatric trauma center over a 15-year period...

BACKGROUND: The pituitary adenoma causing acromegaly is typically resected through a transsphenoidal approach and visualised with an operating microscope or endoscope. We undertook a systematic review and meta-analysis examining the clinical efficacy of endoscopic and microsurgical approaches. METHODS: Relevant studies using either endoscopic or microscopic transphenoid approaches for growth-hormone pituitary adenomas were identified up to Feb 2016. Data were extracted and analyzed according to predefined clinical endpoints...
