What are the postoperative precautions for tumors in the pontocerebellar horn region?

1. Postoperative discomfort and complications: 1. Headache, dizziness, unstable walking: headache, dizziness and unstable walking may occur in different degrees after surgery, which are normal postoperative reactions and are usually completely relieved within 1~2 months after surgery. 2. Facial palsy: Mostly occurs after hearing neuroma surgery. Depending on the degree of injury, different degrees of facial palsy may occur after surgery, manifesting as incomplete eyelid closure, crooked mouth and slanted eyes, cheek puffing, etc., especially in the early postoperative period, which is more obvious. In severe cases, it usually takes about 3 months to 6 months to resolve. If the facial palsy is complete, a second-stage surgery is required for nerve repair. For postoperative eyelid closure, postoperative eye drops are required to protect the cornea until function is restored. For those whose eyelids cannot be closed at all, temporary or permanent sutures to the eyelids may be required to protect the cornea if necessary. Hearing loss and tinnitus: Hearing loss or tinnitus may persist on the affected side after surgery. For patients with complete preservation of the auditory nerve, most of the hearing can be gradually restored after surgery. 4. Restriction of eye abduction or diplopia: This is due to abducens nerve palsy, which can be recovered after a few weeks or months without special medication. 5, trigeminal nerve palsy: manifested as the affected side of the head and facial skin and tongue, mouth sensory loss, bite weakness, chewing difficulties, open mouth jaw deviation to the affected side, etc., mostly due to intraoperative pull on the trigeminal nerve, can be oral methylcobalamin tablets to assist in treatment, generally after a few weeks can gradually alleviate. 6. Posterior group cranial nerve dysfunction: manifested as choking on water, swallowing difficulty, hoarseness, coughing weakness, etc., because the posterior group cranial nerve is mostly preserved intact, so most of them can be gradually relieved within a few weeks to a few months after surgery, no special drug treatment is needed, it is necessary to pay attention to slow drinking when eating and drinking to prevent food or water from choking into the lungs, for patients with a lot of sputum should encourage patients to cough more sputum to prevent lung infection. 7. Cerebrospinal fluid leakage: If the postoperative incision shows obvious local swelling, obvious fluctuating sensation on pressure, subcutaneous fluid accumulation, fever and other manifestations, or continuous flow of colorless and transparent fluid from the external ear canal, cerebrospinal fluid leakage may occur, and it is necessary to follow up with the hospital as soon as possible and ask the specialist to guide further treatment, and if necessary, secondary surgical repair is required. Life precautions 1. It is advisable to eat easily digestible food within 1 month after surgery, avoid eating too cold or too spicy food, and avoid smoking and alcohol. 2. Rest for at least one month after surgery, and recuperate in a quiet environment, avoid strong mental labor and prohibit strenuous exercise. 3. Post-operative review notes Review time: We will generally review the hearing and MRI of the patient before discharge. Three months after discharge, patients should come to the hospital again for review. The interval of subsequent reviews will be determined by the surgeon in charge according to the results of the first review. Patients with cholesteatoma or epidermoid cyst should have DWI serial scan, and patients with auditory neuroma should also go to ENT department for pure tone audiometry and auditory brainstem evoked potential examination. Note for review: If local conditions allow, MRI can be performed at the local hospital, and medical records and pre- and post-operative imaging data (including CT and MRI films) should be brought to the review.
