OBJECTIVE Patients treated for Chiari I malformation (CM-I) with posterior fossa decompression (PFD) may occasionally and unpredictably develop postoperative hydrocephalus. The clinical risk factors predictive of this type of Chiari-related hydrocephalus (CRH) are unknown. The authors' objective was to evaluate their experience to identify risk factors that may predict which of these patients undergoing PFD will develop CRH after surgery. METHODS The authors performed a retrospective clinical chart review of all patients who underwent PFD surgery and duraplasty for CM-I at the Primary Children's Hospital in Utah from June 1, 2005, through May 31, 2015...

OBJECTIVE In acute traumatic brain injury, decompressive craniectomy is a common treatment that involves the removal of bone from the cranium to relieve intracranial pressure. The present study investigated whether neurological function following a severe spinal cord injury improves after utilizing either a durotomy to decompress the intradural space and/or a duraplasty to maintain proper flow of cerebrospinal fluid. METHODS Sixty-four adult female rats (n = 64) were randomly assigned to receive either a 3- or 5-level decompressive laminectomy (Groups A and B), laminectomy + durotomy (Groups C and D), or laminectomy + duraplasty with graft (Group E and F) at 24 hours following a severe thoracic contusion injury (200 kilodynes)...

OBJECT: Suboccipital decompression and duraplasty is considered the treatment of choice for Chiari-I-malformation. Several studies have shown improvement of neurophysiological parameters during decompressive surgery in pediatric patients. However, there is no evidence of the beneficial role of intraoperative neuromonitoring in adults. METHODS: A total of 39 consecutive patients (25 female, age 41.1±14.5 years [mean±SD]) underwent suboccipital decompression for the treatment of symptomatic Chiari-I-malformation senior neurosurgeon and his team...

We propose a double layered (intradural and epidural patch) duraplasty that utilizes Lyoplant and Duraseal. We examined a 47-year-old woman after decompression for thoracic ossification of posterior longitudinal ligament was performed in another hospital. On postoperative day 7, she complained of weakness in both legs. Postoperative magnetic resonance imaging (MRI) showed cerebrospinal fluid (CSF) collection with cord compression. In the operative field, we found 2 large dural defects on the ventral dura mater...

BACKGROUND: A number of different surgical techniques have been used through the years to address Chiari I malformation (CMI). METHODS: This article describes how we surgically manage CMI at two high-volume centers. We call the technique the minimally invasive subpial tonsillectomy (MIST). The technique consists of a minimalistic dissection and craniectomy with a short, linear durotomy for the subpial tonsillar resection. The dura is closed without the use of a duraplasty...

BACKGROUND: A large variety of biological and artificial materials are employed in dural repair, each of them with major limitations. Autologous grafts have limited availability and require an additional incision and surgical time. Cadaveric preparations and heterologous materials entail the risk of iatrogenic transmission of prions, whereas synthetic substitutes have been reported to cause inflammatory reactions and graft rejection. An equine-derived pericardium membrane has been developed (Heart(®), Bioteck, Vicenza, Italy) with mechanical and safety-related features that could make it suitable for neurosurgical application...

The treatment of Chiari malformation type 1 (CM-I) with posterior fossa decompression without (PFD) or with duraplasty (PFDD) is controversial. Our aim is to compare the clinical outcome between the two methods for the treatment of CM-I. In this paper, the authors report a systematic review and meta-analysis of operation time, clinical improvement, and complications of PFD compared with PFDD for the treatment of CM-I. Randomized or non-randomized controlled trials of PFD and PFDD were considered for inclusion...

Hypertensive intracerebral hemorrhage (ICH) has high morbidity and mortality rates. Decompressive craniectomy (DC) is generally used for the treatment of cases associated with refractory increased intracranial pressure (ICP). In this study, we investigated the beneficial effects of adding DC and expansive duraplasty (ED) to hematoma evacuation in patients who underwent surgery for large hypertensive ICH. A prospective randomized controlled clinical trial where 40 patients diagnosed having large hypertensive ICH was randomly allocated to either group A or B, each comprised 20 patients...

PURPOSE: Giant cell tumors (GCTs) in the temporomandibular joint (TMJ) region invading the lateral skull base are relatively uncommon. The management of these lesions is still controversial because of their proximity to vital neurovascular structures. Although sporadically reported, the clinical outcomes of such disease after surgery are still largely unknown. MATERIALS AND METHODS: We retrospectively reviewed the records of 28 patients with resectable GCTs in the TMJ region involving the lateral skull base treated from 1994 to 2013...

BACKGROUND: Cerebrospinal fluid (CSF) leakages represent a major complication of skull base surgery. Watertight dural suture is challenging, and different ways to reinforce it have been proposed. Since 6 months, we use locally harvested autologous pericranium graft for dural repair in retrosigmoid approach. METHODS: Retrospectively, we analyzed 27 patients operated on with key-hole retrosigmoid approach from May 2014. In all, autologous pericranium was harvested and inserted as an underlay "hourglass-shaped" plug under the dura plane and stitched to dura...
