Endoscopic third ventriculostomy (ETV) had been previously carried out for the treatment of symptomatic obstructive hydrocephalus. Our hypothesis is that periorbital emphysema developed due to air passing from the intracranial to the extracranial compartment through the ETV burr hole.<P></P>The emphysema resolved spontaneously without any sequelae. To our knowledge, this is the first description of orbital emphysema after posterior fossa surgery in the sitting position.",
