Patients with brain tumors


Hello: Regarding a patient with a brain tumor who has experienced long-term symptoms such as tinnitus and mild headaches, a physician's examination revealed a tumor on the 7th and 8th cranial nerves, leading to surgical intervention.
Afterward, the patient developed the inability to close their eyes while sleeping and subsequently underwent eyelid suturing as per the doctor's recommendation.
Currently, the patient's condition includes: 1.
One eye is larger than the other.
2.
Occasional side effects from medication.
I would like to ask: 1.
After damage to the cranial nerves, is it true that healing is not possible? 2.
Why is long-term medication still necessary after brain surgery? Thank you.

Dr. Hou Shouxian reply Surgery


This issue is not within Dr.
Hou Shou-Hsien's area of expertise, so it has been referred to Dr.
Zheng Zhong from the neurosurgery department for a response.
The reply is as follows: Based on your description, you are likely experiencing symptoms related to an acoustic neuroma (vestibular schwannoma, affecting the eighth cranial nerve), which has resulted in facial nerve injury (seventh cranial nerve) after surgery.
This has led to the inability to close one eye and decreased tear production.
To prevent corneal inflammation, the eyelid has been temporarily sutured.
The auditory nerve and facial nerve travel together from the brainstem and exit the skull through the internal auditory canal.
During the surgical removal of the acoustic neuroma, preserving facial nerve function is the most critical step.
However, if the tumor is too large, complete resection may necessitate damaging the facial nerve, resulting in complications such as inability to close the eye and facial asymmetry due to facial nerve paralysis.
If the surgeon believes that the facial nerve was preserved during the operation, the current paralysis may be temporary and could gradually improve with medication and rehabilitation.
However, if the surgeon indicates that the facial nerve was not visible during the procedure or confirms that it was severed, then the facial paralysis would be considered a permanent injury.
Dr.
Zheng Zhong.

Understanding brain tumor patients, particularly those who have undergone surgery, involves recognizing the complexities of their condition, recovery, and ongoing treatment. Brain tumors can significantly impact neurological function, and the surgical removal of these tumors often leads to a range of postoperative effects that require careful management.

1. Healing of Nerve Damage: When a brain tumor affects cranial nerves, such as the 7th and 8th cranial nerves (which are responsible for facial movement and hearing/balance, respectively), damage can occur during the tumor's presence or during surgical intervention. The ability of nerves to heal depends on several factors, including the extent of the damage, the type of nerve involved, and the overall health of the patient. Peripheral nerves have a better capacity for regeneration compared to central nervous system (CNS) nerves. However, cranial nerves can sometimes regenerate, albeit slowly, and the recovery may not be complete. In cases where the nerve has been significantly damaged, patients may experience lasting effects, such as asymmetry in facial features (e.g., one eye appearing larger than the other) or persistent symptoms like tinnitus (ear ringing) or hearing loss.

2. Long-term Medication Use: Following brain surgery, patients often require ongoing medication for several reasons. First, medications may be prescribed to manage symptoms resulting from the surgery or the tumor itself, such as seizures, pain, or inflammation. Corticosteroids, for example, are commonly used to reduce swelling in the brain post-surgery. Additionally, if the tumor was malignant, patients may need adjuvant therapies, including chemotherapy or radiation, which necessitate further medication to manage side effects. Furthermore, medications may be needed to address any hormonal imbalances that arise from the removal of tumors affecting the pituitary gland or other endocrine structures.

3. Postoperative Care and Monitoring: After surgery, it is crucial for patients to have regular follow-ups with their healthcare team. This includes neurologists, oncologists, and rehabilitation specialists who can monitor recovery and adjust treatment plans as necessary. Patients may benefit from physical therapy, occupational therapy, or speech therapy, depending on the specific deficits they experience post-surgery.

4. Psychosocial Support: The emotional and psychological impact of brain tumors and their treatment can be profound. Patients may experience anxiety, depression, or changes in personality. Support groups, counseling, and psychiatric care can be beneficial in helping patients and their families cope with these changes.

5. Education and Resources: For caregivers and patients, understanding the nature of brain tumors and their treatment is essential. Resources such as the American Brain Tumor Association or the National Brain Tumor Society provide valuable information on brain tumors, treatment options, and support networks. Books and educational materials on brain health, recovery strategies, and coping mechanisms can also be helpful.

In conclusion, the journey of a brain tumor patient post-surgery is multifaceted, involving physical, emotional, and cognitive challenges. While nerve damage may not always heal completely, ongoing treatment and support can significantly improve quality of life. Regular communication with healthcare providers and access to educational resources are vital for navigating this complex landscape.
