cerebellopontine angles การใช้

• The cerebellopontine angle is the anatomic space between the cerebellum and the pons filled with cerebrospinal fluid.
• A distinct neurologic syndrome of deficits occurs due to the anatomic proximity of the cerebellopontine angle to specific cranial nerves.
• From its origin, it branches along the inferior portion of the pons at the cerebellopontine angle before reaching the cerebellum.
• They tend to occur off the midline, especially in the so-called cerebellopontine angle or in the basal areas above the pituitary gland.
• Further causes, besides an aneurysm, multiple sclerosis or cerebellopontine angle tumor, include : a posterior fossa tumor, any other expanding lesion or even brainstem diseases from strokes.
• The two lateral apertures provide a conduit for cerebrospinal fluid to flow from the brain's ventricular system into the subarachnoid space; specifically into the pontocerebellar cistern at the cerebellopontine angle.
• The "'translabyrinthine approach "'is a surgical approach to the cerebellopontine angle, or CPA . It is used in the surgical extirpation of lesions of the cerebellopontine angle, including acoustic neuroma.
• The "'translabyrinthine approach "'is a surgical approach to the cerebellopontine angle, or CPA . It is used in the surgical extirpation of lesions of the cerebellopontine angle, including acoustic neuroma.
• This type of injury may rarely be caused by an aneurysm ( an outpouching of a blood vessel ); by an AVM ( arteriovenous malformation ); by a tumor; such as an arachnoid cyst or meningioma in the cerebellopontine angle; or by a traumatic event such as a car accident.
• He described in 1921 an operation for the removal of tumors of the pineal region, in 1922 complete removal of tumors of the cerebellopontine angle ( namely acoustic neuromas ), in 1922 the use of endoscopy for the treatment of hydrocephalus ( " cerebral ventriculoscopy " ), in 1925 sectioning the trigeminal nerve at the brainstem to treat trigeminal neuralgia, in 1928 treatment of M閚i鑢e's disease ( recurrent vertiginous dizziness ) by sectioning the vestibular nerves, in 1929 removal of a herniated disc in the spine, in 1930 treatment of spasmodic torticollis, in 1933 removal of the entire cerebral hemisphere ( " hemispherectomy " ) for the treatment of malignant tumors, in 1933 removal of deep tumors within the ventricular system, in 1935 treatment of carotid-cavernous fistulas ( CCFs ), in 1938 ligation or " clipping " of an intracranial aneurysm, and in 1941 removal of orbital tumors.
