Unexpected complication after lumbar disc surgery, peripheral facial paralysis due to pneumocephalus: A case report.

Background: Pneumocephalus, characterized by air in the cranial cavity, is a rare condition typically associated with surgical procedures but may also result from trauma, infection, or spontaneously. Cranial nerve palsies following pneumocephalus are seldom documented in the literature, and, in particular, facial nerve palsies due to pneumocephalus following lumbar spine surgery have not yet been reported.

Case Description: A 47-year-old male patient underwent surgery due to a herniated disc.
