A patient of head injury was brought to the hospital. Patient was conscious having clear nasal discharge through right nostril. NCCT head was done which revealed non-operable injury to frontobasal area. What is the most appropriate management?
Wait and watch for 4-5 days to allow spontaneous healing Do an MRI to localize the leak and control the discharge endoscopically Put a dural catheter to control CSF leak Approach transcranially to repair the damaged frontobasal region
