Trigeminal neuralgia is a completely curable disease; the key is to get professional medical guidance and choose the right treatment method. Microvascular decompression has enabled tens of thousands of patients with trigeminal neuralgia to receive effective treatment, making it the method of choice for the treatment of primary trigeminal neuralgia. Is it facial palsy if I feel stiffness and numbness in my face after surgery? A small number of patients with trigeminal neuralgia feel some numbness and stiffness on their face after surgery. This is because after the spacers are placed, there is a slight squeezing effect on the trigeminal nerve, and this tiny, continuous squeezing force will stimulate this sensory nerve, making some numbness and stiffness on the face, this condition is not facial palsy, with the recovery after surgery, the trigeminal nerve gradually adapts to this tiny stimulation, and the symptoms will slowly disappear. It usually takes three months or six months. As for facial palsy, it is very unlikely to occur. Why do some patients have hearing loss and tinnitus after surgery? The auditory nerve is actually also around the trigeminal nerve. Some patients have hearing loss and tinnitus after surgery because the auditory nerve was strained during the surgery. However, as the auditory nerve recovers, the hearing loss and tinnitus will gradually decrease until they disappear. Just like the strain on the facial nerve, this is temporary and usually recovers in three to six months. Is postoperative headache, vomiting or fever an intracranial infection? The base of the brain shell, called the skull base, is where the back of the head and the neck meet. There are three fossae at the base of the skull, accommodating different nerves and blood vessels, which are divided into anterior, middle and posterior fossae from front to back. Microvascular decompression is usually performed in the posterior cranial fossa, which strains and squeezes the nerves and blood vessels in the posterior cranial fossa. Generally, after surgery in the posterior cranial fossa, patients will experience some degree of pain, nausea, and vomiting, especially with changes in body position, such as sitting down suddenly, getting up suddenly, turning over, and turning the head, etc. These symptoms will be exacerbated. However, this is not an after-effect of the surgery. Generally, these symptoms will slowly decrease until they disappear 3~5 days after the surgery.
