The standard combined transpetrosal approach (CTPA) is fundamentally an epidural approach that has been quite successfully practiced for many decades. However, it has some disadvantages, such as cosmetic problems, difficulties with custom-tailored petrosectomy, and cerebrospinal fluid (CSF) leakage, as it is a complicated epidural procedure. We describe here a case of primary pontine hemorrhage via intradural CTPA (iCTPA), which is a modified technique of CTPA and includes intradural anterior petrosectomy and partial posterior petrosectomy without mastoidectomy and skeletonization of the sigmoid sinus.

The use of 3-dimensional (3D) videos allows students to visualize surgical procedures from the perspective of the surgeon without missing the essential parts.1 This 3D commented video demonstrates the...
Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disorder caused by antibody to aquaporin-4 (AQP4). NMOSD can infrequently present as a complication of posterior reversible encephalopat...
Endoscopic Intradural Subtemporal Keyhole Approach with Neuronavigational Assistance to the Petroclival and Ventrolateral Brainstem Regions: Quantitative Analysis of Anatomic Exposure and Surgical Freedom.
The purpose of this study was to evaluate the advantages of endoscopy and navigational assistance in the intradural subtemporal keyhole approach and the intradural Kawase approach by studying anatomic...
The combined transpetrosal approach enables wide exposure around the petroclival region by cutting the tentorium and superior petrosal sinus. We often choose this approach for removal of tumors ventra...
Surgical treatment of ventrally located intradural cysts is difficult and controversial. Laminectomy with division of the denticulate ligaments and gentle cord mobilization remains the standard approa...
The purpose of the study is to test the effects of intradural, spinal cord stimulation using a device placed in the same manner as a lumbar drain performed during a standard epidural spina...
This is a research study of patients with diffuse intrinsic pontine gliomas. We hope to learn about the safety and efficacy of treating pediatric diffuse intrinsic pontine glioma patients...
This is a phase 2, single-arm, multi-center study, with a safety review component, designed to evaluate the efficacy and safety of nimotuzumab in approximately 44 patients with recurrent d...
The purpose of this study is to compare the direct anterior approach and the direct lateral approach in primary total hip arthroplasty, regarding the postoperative function and pain, compl...
This phase I trial studies the side effects and best dose of panobinostat in treating younger patients with diffuse intrinsic pontine glioma that is growing, spreading, or getting worse (p...
Benign and malignant neoplasms which occur within the substance of the spinal cord (intramedullary neoplasms) or in the space between the dura and spinal cord (intradural extramedullary neoplasms). The majority of intramedullary spinal tumors are primary CNS neoplasms including ASTROCYTOMA; EPENDYMOMA; and LIPOMA. Intramedullary neoplasms are often associated with SYRINGOMYELIA. The most frequent histologic types of intradural-extramedullary tumors are MENINGIOMA and NEUROFIBROMA.
Group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. It is inherited as an X-linked or autosomal recessive defect. Mutations occurring in many different genes cause human Severe Combined Immunodeficiency (SCID).
Hemorrhage within the orbital cavity, posterior to the eyeball.
Intraocular hemorrhage from the vessels of various tissues of the eye.
Surgical construction of an opening into the CECUM with a tube through the ABDOMINAL WALL (tube cecostomy) or by skin level approach, in which the cecum is sewn to the surrounding PERITONEUM. Its primary purpose is decompression of colonic obstruction.
