Patients with anterior cranial fossa fractures often have an impact on the septal and orbital plates, resulting in significant olfactory nerve damage, hyposmia and loss of smell. When this occurs, the patient should be placed in a semi-recumbent position with the head on the affected side, and the limbs should be kept as sedated as possible to avoid any further movement. Prophylactic antibiotics should be used during treatment to prevent intracranial infections. In addition, pay attention to keep the nasal cavity clean and try not to use cotton balls for blockage to prevent retrograde infection. Patients with intracranial hypertension can be treated with appropriate dehydration and cranial pressure-lowering drugs to help reduce intracranial pressure.
