Preoperative Lumbar Drain Use During Acoustic Neuroma Surgery and Effect on CSF Leak Incidence

Abstract

Postoperative CSF leaks are among the most common complications of acoustic neuroma microsurgery. No formal guidelines exist for elective placement of a preoperative LD to lower the incidence of CSF leaks. Our reported CSF leak incidence with preoperative LD placement is not significantly lower than without LD use, and there is a complication rate associated with LD use.
