Immediate treatment of CSF Rhinorrhoea requires-
(A) Antibiotics and observation (B) Plugging with paraffin guage (C) Blowing of nose (D) Craniotomy
(A) Early cases of post traumatic CSF rhinorrhea are managed conservatively (by placing the patient in propped up position, avoiding blowing of nose, sneezing and straining) and
Prophylactic antibiotics (to prevent meningitis).
Persistent cases are treated surgically by nasal endoscopy or by intracranial route.

According to Scott-Brown’s
Endoscopic closure of CSF leak is now the treatment of choice in majority of patients but it should not be done immediately.
First patient should be subjected to diagnostic evaluation and after site of leakage is confirmed, it should be closed endoscopically.
