Common diseases with medullary lesions include cerebral infarction, cerebral hemorrhage, etc. If the lesion is mild, the swallowing function may be restored in 3~6 months after timely treatment; if the lesion is severe, it may cause irreversible swallowing function damage, and the swallowing function can’t be fully restored to the normal level. Take cerebral infarction as an example, if the lesion site in the medulla oblongata triggers swallowing dysfunction, when the degree of lesion is mild, it does not cause irreversible damage to the nerves, and can be recovered in 3~6 months through standardized treatment and rehabilitation training. If the severity of the lesion is more serious, causing irreversible damage to the nerves, swallowing dysfunction may not be fully recovered, but by insisting on swallowing function rehabilitation training can improve the function and help the patient to return to normal life. The exact time for recovery of swallowing function in patients with medullary lesions needs to be assessed according to the cause and extent of the lesion, etc. Patients should consult a doctor in time for a clear diagnosis and relevant treatments, in order to regain their health as soon as possible.
