Long-term outcomes following endoscopic repair have been well described. Therefore, beta-2 transferrin is located only within the CSF, perilymph, and aqueous humor. Drainage increases while leaning forward with head down 4. Disruption of the barriers between the sinonasal cavity and the anterior and middle cranial fossae is the underlying factor leading to the discharge of CSF into the nasal cavity. A history of headache and visual disturbances suggests increased intracranial pressure. Symptoms of CSF Rhinorrhea.
Beta-trace protein also known as prostaglandin D synthase, this protein is synthesized primarily in arachnoid cells, oligodendrocytes, and the choroids plexus within the central nervous system (CNS). Beta-trace protein test is not specific for side or site of leak and can be difficult to collect if the leak is intermittent. The resulting communication with the central nervous system (CNS) can result in a multitude of infectious complicati…
J Neurol Surg B Skull Base. In patient cohorts that underwent such evaluation and treatment (with acetazolamide or CSF shunting), the repair success rate was 92.82%, compared with 81.87% in patients who were not actively managed for increased intracranial pressure 21). google_ad_client: "ca-pub-9759235379140764", Rarely, the leaked fluid may be observed through the nose. SYMPTOMS • Headache, that gets worse on sitting and improves on lying down • Nausea • Neck stiffness • CSF drainage from nose; DIAGNOSIS - Medical history - MRI Brain & spine - CT Scan with contrast - Radioisotope test of the CSF to track the leakage. 2009 Feb;17(1):28-32.

Evaluation of a suspected leak should include testing of rhinorrhea or otorrhea for beta-2 transferrin, a compound found only in CSF and perilymph making it a highly specific and sensitive test. Beta-2 transferrin is stable at room temperature for approximately 4 hours; therefore, immediate refrigeration following collection is recommended. Mirza S, Thaper A, McClelland L, Jones NS. Even if the tumor itself does not lead to CSF rhinorrhea, the resection typically results in immediate leakage. In one study, pituitary tumor resection made up nearly half of cases where tumor removal led to confirmed CSF rhinorrhea 6).
