A spinal extradural arachnoid cyst (SEAC) results from a rare small defect of the dura matter that leads to cerebrospinal fluid accumulation and communication defects between the cyst and the subarachnoid space. There is consensus for the treatment of the dural defect, but not for the treatment of the cyst. Some advocate a total resection of the cysts and repair of the communication site to prevent the recurrence of a SEAC, while others recommended more conservative therapy. Here we report the outcomes of selective laminectomy and closure of the dural defect for a 72-year-old and a 33-year-old woman...

John T Smith
BACKGROUND: Congenital gibbus deformity of the spine associated with myelodysplasia is a challenging problem in the growing child and is commonly associated with skin breakdown and chronic infection. Surgical solutions including kyphectomy, flap closure of the skin, and early spinal fusion are associated with a high rate of complications and, ultimately, a short trunk due to stoppage of spinal growth. The purpose of this article is to describe our early results in using a rib-based distraction to the pelvis without vertebral resection and fusion to manage this deformity...

Idiopathic spinal cord herniation (ISCH) is a relatively rare and frequently misdiagnosed condition. It preferentially affects women and causes progressive thoracic myelopathy that presents as a Brown-Séquard syndrome or as spastic paraparesis. Although its etiology and pathogenesis are controversial, ISCH is characterized by the presence of an anterior dural defect that allows the incarceration of a segment of the cord. Typically, a C-shaped ventral displacement and kinking of the cord are visible on sagittal MRI...

BACKGROUND: Neural tube defects are debilitating birth defects that occur when the developing neural plate fails to close in early gestation. Arsenic induces neural tube defects in animal models, but whether environmental arsenic exposure increases risk of neural tube defects in humans is unknown. METHODS: We describe a new case-control study in Bangladesh, a country currently experiencing an epidemic of arsenic poisoning through contaminated drinking water. We plan to understand how arsenic influences risk of neural tube defects in humans through mechanisms that include disruption of maternal glucose and folate metabolism, as well as epigenetic effects...

BACKGROUND: Nonpenetrating titanium clips create no suture holes and thereby reduce cerebrospinal fluid leakage after dural closure. However, no data exists regarding metallic artifacts caused by these clips during postoperative neuroimaging. We aimed to evaluate clip-related artifacts on postoperative MR images of 17 patients who underwent spinal surgery. METHODS: A phantom study evaluated the size of metallic artifacts, while a clinical study evaluated the quality of postoperative spinal MR images...

BACKGROUND: Incidental durotomy is a relatively common complication in spinal surgeries, and treatment of persistent cerebrospinal fluid (CSF) leakage is still challenging, especially in cases for which "watertight" suturing is inapplicable. The usefulness of a non-vascularized perifascial areolar tissue (PAT) graft was recently emphasized for plastic and skull base surgeries. Its hypervascularity allows for early engraftment and long-term survival, and its flexibility is advantageous in fixing defects of complex shapes in limited surgical spaces...

Posterior fossa surgery is demanding and hides a significant number of obstacles starting from the approach to the wound closure. The risk of cerebrospinal fluid (CSF) leakage in posterior fossa surgery given in the literature is around 8%. The present study aims to introduce a sandwich closure of the dura in posterior fossa surgery, which reduces significantly the number of CSF leaks (3.8%) in the patients treated in our department. Three hundred and ten patients treated in our hospital in the years 2009-2013 for posterior fossa pathologies were retrospectively evaluated...

BACKGROUND AND AIM: Large skull base defects are extremely difficult to treat and have a severe impact on patients' physical appearance and functional aspects. These extensive defect zones are mainly caused by trauma, surgical interventions, or wide tumor excision. High-level microsurgical techniques are necessary to provide sufficient treatment. The aim of this study is to describe successful reconstructive strategies for surgical treatment. METHODS: Nine patients with skull base defects were treated in our department from 2008 to 2014 (n = 9)...

PURPOSE: Cephalocranial disproportion is a symptomatic condition related to a volume discrepancy between the calvarial vault and the brain. Traditional expansion techniques are unfavorable in older children due to inadequate dural ossification, lack of bone pliability, and limited future growth potential. The authors review their experience using distraction to close bone defects in this setting. METHODS: A retrospective analysis was performed of all patients treated using distraction in this setting by a single surgeon...

#18
Han-Song Sheng, Nu Zhang, Jian Lin, Fen-Chun Lin, Bo Yin, Mao-de Wang
OBJECTIVES: Surgical management of cranial burst fracture (CBF) usually involves craniotomy to remove the devitalized brain tissues, followed by watertight repair of dural tears. However, there were times when the dural tear was so extensive that a substantially large bone flap would have to be removed in order to expose the retracted dural margins before it could be repaired. In such cases, strict dural repair would incur a significantly higher risk of damages to the surrounding neural tissues and severe bleeding, especially when the fracture was in the vicinity of eloquent cortical areas and sinus...

Mansher Singh, Joseph A Ricci, Ian F Dunn, Edward J Caterson
BACKGROUND: Titanium cranioplasty is commonly used for surgical closure of skull defects post craniectomy. Superficial implantation of the mesh can result in discomfort, palpability, and in extreme patients, exposure of the mesh. Exposed titanium mesh can be complicated by infections and often requires implant revision or removal. Generally, the contour of the titanium mesh is camouflaged in the hairline of the patient and any aesthetic complication can remain inconspicuous. However, in the frontal bone position the thin hairless forehead skin often may not easily hide the contour of the underlying titanium mesh...

BACKGROUND: Microvascular decompression (MVD) represents the most effective and safe surgical option for the treatment of trigeminal neuralgia since it was first popularized by Jannetta 50 years ago. Despite several advances have been proposed, the rate of complications as cerebellar and vascular injury, hearing loss, muscular atrophy, cerebrospinal fluid (CSF) leak, postoperative cutaneous pain and sensory disturbances, remain still actual and may negatively affect the outcome. We propose some technical nuances of the surgical procedure we used in our recent series...
