Late metastasis of an intracranial meningioma to the hard palate.

Meningiomas are benign neoplasms that arise from cellular elements of the meninges. Although meningiomas are usually considered as benign tumors, they have a potential to become aggressive and to metastasize to the extracranial structures. Distant metastasis most commonly occurs in lung, liver, and long bones.

Background: We hypothesize that dexmedetomidine (DEX), a selective α(2) adrenergic receptor agonist, may affect the intraoperative blood loss and clotting tests such as prothrombin time, activated partial thromboplastin time, and international normalized ratio in children undergoing adenotonsillectomy (ADT).

Methods: Sixty patients scheduled for elective ADT under general anesthesia. The patients were randomly assigned to receive either DEX 0.
