Summary
A new surgical approach for first-division trigeminal neuralgia (tic douloureux) offers prolonged pain relief while preserving corneal sensation. This technique avoids risks associated with other trigeminal neuralgia surgeries.
Area of Science:
- Neurosurgery
- Facial Pain Management
Background:
- First-division trigeminal neuralgia (tic douloureux) refractory to medication poses surgical challenges, particularly regarding corneal sensation preservation.
- Conventional treatments may not always provide lasting relief or carry risks of neurological deficits.
Observation:
- A novel surgical technique involves intraorbital resection of the supratrochlear and supraorbital nerves via an upper eyelid incision.
- This approach was performed on four patients with medication-refractory trigeminal neuralgia.
Findings:
- Three of four patients with typical idiopathic trigeminal neuralgia experienced sustained pain relief for 22-25 months post-surgery.
- All patients developed temporary frontal nerve distribution anesthesia and postoperative ptosis, which resolved within 4 months.
- One patient with atypical facial pain did not achieve pain relief.
Implications:
- This surgical option may offer durable pain control for first-division trigeminal neuralgia, preserving essential facial sensation.
- The procedure avoids direct manipulation of the trigeminal root and ganglion, mitigating risks of facial motor dysfunction and widespread anesthesia.
