After craniotomy for cholesteatoma in the ventricle of the brain, if the patient recovers well, there may be no other obvious symptoms, but some patients may have sensory disorders, cerebellar damage, obstructive hydrocephalus and other symptoms. 1. Sensory disorder: cholesteatoma resection in cranial ventricle may affect nerve nuclei and peripheral cerebral nerves to a certain extent, so patients may have sensory disorders, such as facial paralysis and numbness of face, etc. After the operation, the patients will have no other obvious symptoms. 2. Cerebellar damage: patients may suffer from cerebellar damage after the surgery, which may lead to symptoms of balance disorder, such as unsteady walking, hobbling gait, etc., and a few patients may suffer from dysarthria. 3. Obstructive hydrocephalus: If bleeding or adhesion occurs during the surgery, patients may suffer from obstructive hydrocephalus, which may cause nausea, vomiting, headache and other uncomfortable symptoms. It is recommended that patients maintain good dietary habits during the recovery process, do not stay up late, and should go to the hospital and consult the doctor in time if they have any discomfort symptoms.
