Why is there still pain after trigeminal nerve surgery?

Pain after trigeminal nerve surgery may be due to incomplete recovery, inadequate treatment, or stimulation from bleeding.

1. Incomplete Recovery

Pain that persists after surgical treatment of the trigeminal nerve may result from incomplete recovery. Specifically, even after surgical decompression of the trigeminal nerve, nerve degeneration typically does not resolve immediately and requires a certain period of self-repair and healing before pain gradually subsides.

2. Inadequate Treatment

Trigeminal neuralgia usually causes recurrent, severe pain in the area of one side of the face innervated by the trigeminal nerve, often described as stabbing or burning pain. If pain persists after surgery, it may be due to incomplete separation of the nerve from blood vessels during the procedure or re-compression caused by detached secretions.

3. Bleeding Stimulation

Bleeding commonly occurs after surgical treatment of the trigeminal nerve. If significant or severe irritation symptoms develop following the bleeding, this may lead to persistent postoperative pain in the patient.
