OBJECTIVE: To examine tumor control, hearing preservation, and complication rates after frameless fractionated stereotactic radiosurgery (SRS) in patients with vestibular schwannomas (VS). METHODS: Thirty seven treated SRS from 2002 to 2011 were retrospectively analyzed. Ninety five percent 25 Gy 5 fractions, targeting a median volume of 1.03 cc (range 0.14-7.60). RESULTS: With follow-up 4.25 years (range, 15months-9 years), no tumors required an additional treatment resulting 100% control...
Effective short-term outcomes have been well documented for trigeminal neuralgia (TN) patients treated with Gamma Knife radiosurgery (GKRS) reported success rates of 70-90 % median follow-up intervals 19-75 months. Fewer series, however, described uniform long-term data. In this study, we report our institutional in GKRS after a minimum 36 months.Thirty-six consecutive medically intractable TN received radiation dose 45 Gy applied single 4-mm isocenter to the affected nerve. Follow-up data...
A handful of studies have reported outcomes with CyberKnife radiosurgery (CKRS) for the treatment trigeminal neuralgia. However, follow-up has been short no minimum required and included patients duration symptoms. Here we report our institutional experience on a 1 year median 28 months (mean 38.84 months). Twenty-five medically surgically intractable TN received CKRS mean marginal radiation dose 64 Gy applied to an average isodose line 86% affected nerve. Follow-up data were obtained by...
Single-position lateral lumbar interbody fusion (SP-LLIF) has recently gained significant popularity due to increased operative efficiency, but it remains technically challenging. Robot-assisted percutaneous pedicle screw (RA-PPS) placement can facilitate in the position. The authors have reported their initial experience with SP-LLIF RA-PPS position, and they compared this accuracy that of prone
Abstract BACKGROUND Cadaveric studies on surgical anatomy and approaches are hampered by the limited number of specimens. Virtual reality (VR) technology can overcome this limitation, allowing for more in-depth statistical analysis data. OBJECTIVE To determine benefit a supraorbital ridge osteotomy in craniotomy targeting (1) anterior communicating artery complex (ACOM), (2) lesion 25 mm above tuberculum sellae, using large dataset generated VR. METHODS Computed tomography scans 30 subjects...
Prior studies have identified two anatomically and neurochemically distinct cellular compartments within the mammalian striatum, termed striosomes matrix, which express μ-opioid receptors (μOR) EphA4, respectively. Here we identify characterize an additional compartment in rat striatum composed of neurons that EphA7. In situ hybridization immunohistochemical data indicate expressing EphA7 mRNA protein are arranged a banded "matrisome-like" pattern confined to matrix dorsal striatum. Within...
OBJECTIVE Despite advancement of surgical techniques, the attachments petroclival meningiomas near central clival depression (CCD) remain difficult to visualize. With existing methods, amount tumor CCD that is inaccessible through various approaches cannot be compared. Tumors distort brainstem, changing size operative corridor for some but not all approaches; therefore, using cadavers with normal posterior fossae makes it impossible compare different tumor. The authors used virtual reality...
Background and Purpose: Middle cerebral peduncle (MCP) edema has been described to occur in up 35.7% of vestibular schwannomas (VS). Tumor size associated with the occurrence MCP FLAIR signal seems be long-term thickness MCP. However, no clear data shows any eventual correlation between pre postoperatively postoperative cranial nerve outcomes. The aim this retrospective study is investigate correlations outcomes surgically treated VS patients.
Introduction: Elevated neutrophil to lymphocyte ratios (NLR) has been shown be a predictor of vestibular schwannoma (VS) growth, as well prognostic factor in other cancers. Middle cerebral peduncle (MCP) MRI FLAIR and thickness changes are commonly observed VS. This study investigates the correlations between NLR MCP VS pre- postoperatively.
Background and Purpose: Vestibular Schwannomas (VS) represent 6–8% of all intracranial tumors have recently been implicated to be dependent on inflammatory processes. Atorvastatin is currently one the most frequently prescribed medications in United States. It has shown literature that atorvastatin anti-inflammatory effects. However, there are no studies relating vestibular schwannomas. This study attempts explore relationship between perioperative cranial nerve (CN) outcomes neutrophil...
Background and Purpose: Elevated neutrophil to lymphocyte ratios (NLR) has been shown be predictive of vestibular schwannoma (VS) growth, a prognostic factor in other cancers. This study investigates the correlations between NLR cranial nerves commonly affected by VS, including vestibulocochlear nerve (CNVIII), facial (CNVII), trigeminal (CNV).
We present a case in which retrocondylar far-lateral approach was utilized to resect hemangioblastoma at the craniocervical junction. The patient 33-year-old man presenting with 2 months of symptoms referable compression junction (i.e., dizziness and gait instability). Though neurologically intact on exam, his imaging demonstrated highly vascular cystic lesion dorsolateral medulla left consistent hemangioblastoma. Virtual reality software critical visualize patient's relationship vertebral...
Background: The portion of the occipital condyle that is "safe" to remove remains controversial in transcondylar approach. We aimed correlate gain exposure with incremental removal determine if there a point where further drilling yields diminishing gains.
