View clinical trials related to Cerebellopontine Angle Tumor.
Filter by:Skull base tumors are a type of tumor that grow in the area of several skulls behind the cranial cavity. The incidence rate is 2 to 18 per 100,000 people per year; males and females are likely to have a proportional difference in the types of skull base tumors. Cerebellopontine angle (CPA) tumors are the most common neoplasms in the posterior skull base,accounting for 5-10% of skull base tumors.Some different kinds of tumors can grow in cerebellopontine angle. The tumors are more likely to cause some symptoms when they grow large enough to put pressure on the brain. A common traditional treatment for skull base tumors is neurosurgery-craniotomy. However, after the operation, brain may be injured with hematoma, and the instruments used are in contact with the brain. It is still inevitable that there will have complications of minor and major nerve damages, such as facial paralysis,trigeminal neuralgia, tinnitus, sports disorders (ataxia) and so on. Acupuncture has a unique effect on the treatment of the human nervous system. Aim of the study is used acupuncture to improve the complications of the surgery of Cerebellopontine angle tumors in skull base.
compare the operating condition of two different levels of muscle relaxation on facial nerve monitoring using transcranial motor evocked potential in CPA surgery . - To Estimate End to start facial nerve MEP amplitude ratio - To determine the effect of neuromuscular relaxant degrees on recovery and - Assessment of propofol doses needed for enhancement of early recovery and ambulation.
It is a Prospective descriptive hospital based clinical study to determine the value of introduction of endoscope after microscopic excision of cerebello-pontine angle lesions to estimate the following : 1. Intraoperative judgement of lesions excision, residual parts, visualization and operative corridor pre and after endoscope introduction. 2. Post-operative tumor control confirmed comparison between pre and postoperative MRI. 3. Postoperative complications, advantages and disadvantages compared with these when use pure microscopic excision from the literature
