What are the reasons for failure of trigeminal nerve surgery?

Generally, the main reasons for trigeminal nerve surgery failure include anatomical variations of the nerve, abnormal patient coagulation function, pre-existing nerve adhesions, postoperative intracranial infection, and recurrent trigeminal neuralgia. If symptoms persist or discomfort occurs after surgery, it is recommended to promptly visit a regular hospital for evaluation. Detailed analysis is as follows:

1. Nerve Anatomical Variations

Some patients have congenital variations in the anatomical structure of the trigeminal nerve and surrounding blood vessels and brain tissue, such as abnormal vascular pathways or displaced nerve branches. These variations make it difficult to accurately locate the lesion during surgery, potentially leading to incomplete decompression or nerve damage, which can cause surgical failure.

2. Abnormal Coagulation Function

If a patient has coagulation disorders or has been taking anticoagulant medications long-term, excessive bleeding during surgery may occur, affecting the clarity of the surgical field and potentially preventing completion of the planned procedure or causing postoperative hematomas that compress the nerve, leading to surgical failure.

3. Preoperative Nerve Adhesions

Long-term inflammation or tumor compression can cause the trigeminal nerve to adhere to surrounding brain tissue and blood vessels, making it difficult to completely separate the nerve from the adhered tissues during surgery. This can lead to incomplete decompression and persistent pain after surgery. Prior to surgery, nerve nutrition medications such as mecobalamin tablets, vitamin B1 tablets, and mouse nerve growth factor injection may be used under a physician's guidance to reduce nerve inflammation.

4. Postoperative Intracranial Infection

If aseptic techniques are not strictly followed during surgery or if the patient has a low immune status after surgery, intracranial infection may occur, leading to poor wound healing and impaired nerve function, which affects surgical outcomes. Postoperative infection prevention or control may require the use of ceftriaxone sodium injection, vancomycin injection, or levofloxacin hydrochloride injection under a physician's guidance.

5. Recurrent Trigeminal Neuralgia

After surgery, the trigeminal nerve may again become compressed by surrounding blood vessels, experience poor myelin sheath repair, or have unresolved preoperative causes, which can lead to recurrence of trigeminal neuralgia,表现为 a return of pain after a period of relief. Patients with mild symptoms may use carbamazepine tablets, oxcarbazepine tablets, or gabapentin capsules under a physician's guidance to alleviate pain.

In daily life, patients should truthfully inform their physician about their medical history and medication use before surgery; maintain regular作息 after surgery and avoid熬夜 to reduce nerve strain; and eat a light diet, avoiding spicy and irritating foods to prevent nerve irritation.
