Reactivation of trigeminal neuralgia following distraction osteogenesis in an 8-year-old child: report of a unique case.

Trigeminal neuralgia is extremely rare in children. No concrete treatment protocols seem to be available for management of this condition in the pediatric population. Although trigeminal neuralgia may achieve remission, the possibility of reactivation of a hitherto quiescent condition cannot be ruled out. We present a case of pediatric trigeminal neuralgia following distraction osteogenesis of the mandible.

Minimally invasive radioguided surgery for parathyroid adenomas (MIRP).

BACKGROUND: Parathyroid adenoma is the most common cause of primary hyperparathyroidism. Conventional surgical management includes bilateral neck exploration with removal of the adenoma(s) and biopsy of one of the other glands with visualization of all glands. It is associated with a risk of permanent hypoparathyroidism. Radioguided excision of parathyroid adenoma is a widely accepted technique which provides accurate localization and complete excision of the lesion with low morbidity. We report our experience with this technique. METHODS: We performed radioguided excision of parathyroid adenomas in 15 patients. All of them had preoperative localization of the adenoma using a dual tracer, dual phase 99mTc-Sestamibi scan. A dose of 8-10 mCi of 99mTc-Sestamibi was injected intravenously 2 hours before surgery. Under local anaesthesia, surgical excision of the lesion was done after localizing it using a hand-held gamma probe. Complete excision was confirmed by frozen. section of the excised lesion and an intraoperative quick parathormone assay. RESULTS: The 99mTc-Sestamibi scan revealed an increased uptake by the adenoma in all patients and complete excision was possible in all the patients. Frozen section confirmed the diagnosis and the quick parathormone assay (within 15 minutes) revealed a drop in parathormone levels to < 50% after excision in all of them. Three patients developed hypocalcaemia postoperatively and were treated with intravenous calcium supplementation. At a follow up of 2-29 months, all the patients were normocalcaemic. The renal functions improved in 2 of 6 patients who had renal failure. CONCLUSION: Minimally invasive radioguided excision of parathyroid adenomas is a simple, safe and effective technique associated with a low morbidity and can be done as a day-care procedure.
