Loss of taste and smell after a car accident is mostly due to temporary or permanent loss of function caused by compression, injury or severance of the taste and smell nerves. Depending on the condition of the injury, you should choose to take medication that nourishes the nerves and improves circulation, or have timely surgery in order to restore function. Loss of taste and smell after a car accident may be due to damage or compression of the taste and smell nerves. 1. If the loss of taste and smell is caused by intracranial hematoma or edema of brain tissue compressing the nerves due to the car accident, surgery can be used to relieve the compression and gradually restore the sense of smell and taste. 2. If the taste and smell nerves are slightly damaged and the nerve function is temporarily impaired, taking drugs that nourish the nerves and improve the circulation, such as methylcobalamin and ginkgo biloba, etc., may promote the repair of the nerves and reverse the temporary loss of taste and smell. If the above nerves are severed or more than 90% of the nerve activity is lost due to the car accident, it is usually impossible to recover. It is recommended that the patient actively consult a doctor to improve the examination, fully assess the degree of nerve damage and causative factors, and follow the doctor’s instructions to standardize the use of medication and treatment.
