Cerebellar Mutism
Temporary loss of speech following posterior fossa surgery, particularly involving the cerebellar vermis.
Full Definition
Cerebellar mutism is a well-recognized complication following posterior fossa surgery, characterized by temporary inability to speak despite preserved consciousness and comprehension. This syndrome most commonly occurs after resection of tumors involving the cerebellar vermis, particularly medulloepitheliomas and ependymomas in pediatric patients. The mutism typically develops 1-2 days post-operatively and may be accompanied by other behavioral changes, ataxia, and emotional lability. While often reversible, the condition can significantly impact patient recovery and quality of life. In clinical documentation, early recognition and appropriate supportive care are essential, and families require counseling about the typically temporary nature of this complication.
Usage
Usage note: Typically temporary; important complication to discuss in preoperative counseling.
