title: [Ultrasound-guided minimally invasive neurosurgery in treatment of cranial tumors: clinical study].
abstract: OBJECTIVE
  To explore the applicability of ultrasound-guided minimally invasive neurosurgery in treatment of intracranial tumors.
  
  
  METHODS
  Thirty five patients with intracranial tumors diagnosed with preoperative CT and MRI underwent craniotomy. Intraoperative real-time monitoring ultrasound was conducted to detect the location, size and depth of the cerebral masses so as to determine the appropriate approach. At the end of operation, ultrasonography was used to explore the range of residue tumors.
  
  
  RESULTS
  All the 35 patients acquired exact location of the tumors with ultrasound manifesting different levels of echo. According to the pathological results, the lesions of 32 patients (91%) were totally removed and 3 patients (9%) underwent subtotal resection. No infection was found.
  
  
  CONCLUSIONS
  Ultrasound-guided minimally invasive neurosurgery is an effective real-time tool to localize brain tumors. It will provide a significant guidance for minimally invasive neurosurgery.
