Ultrasound determination of cerebrospinal fluid shunt patency. Technical note.

abstract：OBJECT:The combined petrosal approach is a suitable technique for the resection of medium-to-large petroclival meningiomas (PCMs). Multiple technical modifications have been reported to increase the surgical corridor, including the method of dural and tentorial opening. The authors describe their method of dural openin...
