Percutaneous Trigeminal Rhizotomy for Facial Pain Secondary to Head and Neck Malignancy
Bibliographic record
Abstract
BACKGROUND: Nearly 80% of patients with head and neck cancers experience facial pain related to their tumor or treatment. The majority obtain pain relief with appropriate medical treatment. Occasionally some remain refractory to all analgesics or cannot tolerate the accompanying side effects. They may benefit from surgical intervention. OBJECTIVES: We report a case of medically intractable facial pain secondary to squamous cell carcinoma of the tongue that was successfully treated with percutaneous trigeminal rhizotomy. METHODS: Percutaneous trigeminal radiofrequency rhizotomy involves thermoablation of the trigeminal nerve within Meckel's cave by an electrode inserted through the cheek and foramen ovale. RESULTS: Facial pain was successfully controlled postoperatively. DISCUSSION: Percutaneous trigeminal rhizotomy is a surgical option for managing nociceptive pain secondary to a head and neck malignancy. This technique, last reported in the literature almost 30 years ago, must not be forgotten by the next generation of oncologists, pain specialists, and neurosurgeons.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
