Core Tip
Core Tip: The auditory brainstem implant (ABI) is a significantly beneficial treatment to restore hearing sensations for neurofibromatosis type 2 (NF2) patients. However, there is no ideal method in assisting the placement of ABI. The asleep-awake-asleep technique was applied for awake craniotomy and hearing test via the retrosigmoid approach for acoustic neuromas resections and ABI in four NF2 patients. ABI electrode arrays were placed in the awake phase with successful intraoperative hearing tests in three patients. There was one uncooperative patient whose awake hearing test needed to be aborted due to her restlessness. In all cases, tumor resection and ABI were performed safely. The awake craniotomy is beneficial to improve the accuracy of electrode placement in the ABI and meanwhile reduces non-auditory side effects.
