Step-by-step explanation:
Post infratentorial surgery refers to a surgical procedure in which the incision is made at the nape of the neck, typically for accessing the lower part of the skull and brain. After this type of surgery, the patient's positioning becomes crucial for proper recovery and care. The patient is usually placed in the prone position, which means lying face down. This position allows for better access to the surgical site, provides optimal drainage, and reduces the risk of complications such as fluid collection or pressure on the brain.
