1. Surgery Overview
Cerebellopontine angle (CPA) tumor surgery is performed to remove tumors located in the region where the cerebellum and pons meet the brainstem, near critical structures like cranial nerves and major blood vessels. CPA tumors can be benign (such as acoustic neuromas) or malignant, and they can cause symptoms such as hearing loss, balance problems, and facial weakness. The surgical approach depends on the tumor’s size, location, and type. A common approach is through the posterior fossa via a retrosigmoid or suboccipital craniotomy.
2. Type of Anesthesia
The surgery is performed under general anesthesia, ensuring the patient is fully unconscious and pain-free throughout the procedure.
3. Possible Risks and Complications
Bleeding
Infection
Damage to cranial nerves (potential effects on hearing, facial movement, balance, or swallowing)
Cerebrospinal fluid (CSF) leak
Hearing loss or worsening of existing hearing issues
Facial weakness or numbness
Brainstem injury, which can affect basic body functions
Cerebellar or brainstem swelling
Need for additional treatments, such as radiation or further surgeries
4. Hospital Stay Duration
Patients typically remain in the hospital for 7 to 10 days, depending on the tumor’s characteristics and the complexity of the surgery. Intensive care monitoring may be required initially for neurological and respiratory assessment.
5. Important Post-Operative Care
Regular neurological monitoring, including hearing and balance assessments
Pain management and prevention of infection
Avoidance of strenuous activities and head movements for several weeks
Rehabilitation therapy for balance, hearing, and facial nerve function if necessary
Follow-up imaging (MRI) to ensure complete tumor removal and assess for any complications
Ongoing monitoring for potential recurrence of the tumor
6. Possibility of Recurrence
There is a chance of tumor recurrence, particularly with larger or incompletely removed tumors. Long-term follow-up with MRI scans and clinical evaluations is essential to detect early signs of recurrence. In some cases, radiation therapy may be recommended to reduce the risk of recurrence.
