Pial synangiosis is a method of indirect surgical revascularization developed at our institution for the treatment of moyamoya disease in pediatric patients. Similar surgical principles are employed in adult cases, often performed because of lack of an adequate donor vessel. Standardized protocols, including preadmission for preoperative intravenous hydration and aspirin administration, as well as intraoperative electroencephalography, are routinely employed to minimize operative risk. Perioperative heparinization is not required...

OBJECTIVES: Cerebrospinal fluid leaks are a frequent complication of spinal surgery, with reported rates between 2 and 20%. Management is highly variable and dependent on comorbidities, complexity of the index procedure, and surgeons' experience. Treatment options include primary or delayed repair, with or without spinal drainage. Using a retrospective cohort, the authors aim to identify the appropriate management of iatrogenic spinal cerebrospinal fluid (CSF) leaks. PATIENTS AND METHODS: We queried our institutional database for postoperative spinal CSF leaks between 1/1/2007 and 3/14/2017 using Current Procedural Terminology (CPT) and International Classification of Disease (ICD) codes...

We experienced a case of sphenoid sinus type meningoencephalocele manifesting as severe cerebrospinal fluid (CSF) rhinorrhea. A 35-year-old man became aware of serous nasal discharge 1 year previously, which had gradually worsened. The nasal discharge was diagnosed as CSF rhinorrhea. Head computed tomography (CT) showed several small depressions in the bone of the left middle cranial fossa, and the largest depression extended through the bone to the lateral sphenoid sinus. Head magnetic resonance imaging revealed that the meningoencephalocele projected to the lateral sphenoid sinus, through this small bone defect of the middle cranial fossa...

Background: Intracranial arachnoid cysts are space-occupying lesions that typically remain stable or decrease in size over time. Cysts in infants younger than 1 year of age are remarkably different from those in older children and adults in terms of cyst localization and enlargement. Arachnoid cysts of the posterior fossa (PFACs) are very rare in infants and do not typically grow or present with clinical symptoms, such that surgical treatment is generally considered to be unnecessary...

BACKGROUND: Intracranial pneumocephalus is a well-known clinical entity most frequently caused by trauma and intracranial surgery. A less frequent cause of intracranial pneumocephalus is spontaneous pneumocephalus. Spontaneous pneumocephalus can have an intraventricular extension, causing tension intraventricular pneumocephalus. CASE DESCRIPTION: We present an exceptionally rare case of spontaneous otogenic intraventricular pneumocephalus in a 58-year-old female that resulted in a decline in mentation and neurologic deficit...

BACKGROUND: Dural closure after intracranial procedures is considered crucial to reduce postoperative complications such as pseudomeningocele (PM), cerebrospinal fluid (CSF) leaks, hydrocephalus, and infections. However, watertight dural closure (WTDC) is often difficult to achieve, and dural substitutes often are used. We describe our experience with non-WTDC in children. METHODS: Data were collected retrospectively. Redo and craniectomy cases were excluded. Collected data included demographics, surgical etiology, various radiologic parameters, ventricular opening, usage of drains and shunts, dural closure technique, and complications...

BACKGROUND: Basal cell carcinomas (BCC) located in the sun-exposed regions are a serious therapeutic challenge. Therefore early diagnosis and adequate therapy should be of a high priority for every dermatologic surgeon. CASE PRESENTATION: We are presenting a patient with multiple BCCs, located on the area of the scalp, who had been treated several years ago with electrocautery and curettage after histopathological verification. However, the last few years the tumours have advanced, infiltrating firstly the tabula external and a year later the tabula interna of the cranium...

Background: While effective for the repair of large skull base defects, the Hadad-Bassagasteguy nasoseptal flap increases operative time and can result in a several-week period of postoperative crusting during re-mucosalization of the denuded nasal septum. Endoscopic transsphenoidal surgery for pituitary adenoma resection is generally not associated with large dural defects and high-flow cerebrospinal fluid (CSF) leaks requiring extensive reconstruction. Here, we present the posterior nasoseptal flap as a novel technique for closure of skull defects following endoscopic resection of pituitary adenomas...

Cerebrospinal fluid (CSF) leakages of the temporal bone may arise during mastoid surgery. The leakages can have multiple potential etiologies, for instance, using a cutting burr near the bony tegmen or monopolar electrocautery on the surface of the dura mater. In this paper, we introduced an effective and simple technique for the management of CSF leakages of the temporal bone. In a prospective case series, 36 patients (16 males and 20 females) who have had an experience of incidental or inevitable CSF otorrhea or otorhinorrhea during temporal bone surgery were selected...

BACKGROUND: Although a valve-like mechanism has been proposed for expansion of spinal extradural arachnoid cysts (SEACs), the detailed mechanism remains unclear. Moreover, closure of the communication site is essential during surgery, but the method to identify the communication site remains unclear. The aim of this study was to determine the detailed mechanism of expanding SEACs through retrospective analysis of SEAC cases undergoing surgery and to elucidate the characteristics of the communication sites...

BACKGROUND CONTEXT: Endoscopy is increasingly being used for minimal invasiveness and panoramic visualization, with unclear efficacy and safety among spinal intradural mass. OBJECTIVE: The present study aims to compare microendoscopic and pure endoscopic surgery for spinal intradural lesions. MATERIALS AND METHODS: Spinal intradural lesions operated using endoscopic or access ports were categorized into "microendoscopic" (predominant microscope use) or "pure endoscopic" (stand-alone endoscopy) surgery, and were studied with respect to clinico-radiological features, techniques, perioperative course, histopathology, clinical, and radiological outcome at minimum of 3 months...

In the field of neurosurgery, often the dura mater cannot be sutured, and consequently, it requires a duraplasty procedure using a dural fascial graft. Since 1890, various materials have been researched as dura mater substitutes. Amniotic membrane, for example, is suitable as a dural graft material and has been used in neurosurgery since 2012. However, there has been little research on human patient's dural healing after the use of amniotic membrane in their duraplasty procedure. To address this gap, a clinical experimental study was undertaken to evaluate the human dural healing of 16 patients who had undergone duraplasty in decompressive craniectomy surgery at Dr...

Squamous cell carcinoma is known to occur as a serious complication of chronic burns, scars, and ulcers, but very rarely has it been reported to occur in a long-neglected meningocele. The authors wish to present the case of a 21-year-old man who presented to us when a previously asymptomatic meningocele developed a squamous cell carcinoma on the meningocele sac. The squamous cell carcinoma was excised in toto, followed by excision of the redundant meningocele sac. The neural placode was closed and dural closure done with an artificial dural patch...

OBJECTIVE: Duraplasty, a common neurosurgical intervention, involves synthetic or biological graft placement to ensure dural closure. The objective of this study is to advance our understanding of the use of dural substitutes in cranial surgery. METHODS: The PubMed database was systematically searched to identify studies published over the last decade (2007 to 2017) that described duraplasty procedures. Clinical data were disaggregated and analyzed for the comparisons of biological versus synthetic grafts...

Ossification of the ligament flavum in the thoracic spine is an uncommon radiological finding in the Western population but can present with back pain, varying degrees of myelopathy, and even paraplegia on occasion. The authors here present the case of a 50-year-old woman with a history of progressive back pain and symptoms of spontaneous intracranial hypotension who was found to have an ossified ligamentum flavum of the thoracic spine resulting in a dural erosion cerebrospinal fluid leak. Surgery involved removal of the ossified ligament flavum at T10-11, facetectomy, ligation of the nerve root, and primary closure of the dura, which resulted in complete resolution of the patient's symptoms...

BACKGROUND: Cerebrospinal fluid (CSF) leakage occurs in 4% to 32% of cranial surgeries and is associated with significant patient burden and expense. The use of sealant as an adjunct to primary dural closure is assumed to help prevent CSF leakage. OBJECTIVE: To examine the utility of different sealants for dural closure using an in Vitro model. METHODS: We evaluated 9 commonly used dural sealants, including Tachosil (Takeda Inc, Osaka, Japan), Adherus (Hyperbranch Inc, Durham, North Carolina), Duraform (Codman, Raynham, Massachusetts), Tissudura (Baxter, Deerfield, Illinois), Hemopatch (Baxter), TissuePatchDural (Tissuemed, Leeds, United Kingdom), Tisseel (Baxter), Duragen Secure (Integra, Plainsboro, New Jersey), and Duraseal, (Integra)...

Endoscopic endonasal surgery, an innovative surgical technique, is used to approach sinus lesions, lesions of the skull base, and intradural tumors. The cooperation of experienced otolaryngologists and neurosurgeons is important to achieve safe and reliable surgical results. The bath plug closure method is a treatment option for patients with cerebrospinal fluid(CSF)leakage. Although it includes dural and/or intradural procedures, surgery tends to be performed by otolaryngologists because its indications, detailed maneuvers, and pitfalls are not well recognized by neurosurgeons...

When a dural defect is encountered during spine surgery, the dura mater must be reconstituted to minimize the occurrence of minor or major life-threatening sequelae. The neurosurgical literature lacks strategies for managing large dural defects encountered during surgery. The authors describe a 24-year-old man who developed cauda equina syndrome secondary to altered CSF flow in a large thoracolumbar arachnoid cyst. Surgical decompression and fenestration of the arachnoid cyst were performed, and the large dural defect was treated using a multilayer closure with collagen matrix, titanium mesh, and methylmethacrylate...
