Case ReportsGeneral anesthesia for dental treatment in a Williams syndrome patient with severe aortic and pulmonary valve stenosis: suspected episode of postoperatively malignant hyperthermia.
A 28-month-old boy (height, 76 cm; weight, 9.4 kg) diagnosed as having Williams syndrome presented for dental care. We report a case of postoperatively suspected malignant hyperthermia after the administration of general anesthesia for dental treatment in this patient with severe supravalvular aortic stenosis and pulmonary artery hypoplasia. Anesthesia was maintained through the inhalation of nitrous oxide and sevoflurane with oxygen. ⋯ After hospitalization for 4 days, the patient was discharged in good condition. In the present case, general anesthesia was employed for dental treatment despite severe supravalvular aortic stenosis and peripheral pulmonary artery hypoplasia, because conventional dental therapy was very difficult as a result of the patient's mental retardation and hyperkinesia. The present case suggests that the use of volatile agents that could trigger malignant hyperthermia should be avoided wherever possible.

Case ReportsConventional radiographs: are they still the standard in localization of projectiles?
The penetration of air gun pellets in facial soft tissue can cause major problems during the removal of foreign bodies, although conventional radiography, computed tomography, image-guided surgical removal, and ultrasound have been applied to facilitate the procedure. It was the aim of the present case report to introduce a modified intraoperative method for the localization of air gun pellets, based on the use of radiopaque markers in conventional radiographs. A 66-year-old patient attempted to commit suicide by using an air gun. ⋯ The use of radiopaque markers in conventional radiographs in 2 planes allows fast, intraoperative localization of radiopaque foreign bodies within soft tissue. The procedure can be carried out with a conventional x-ray device that should be available in every oral and maxillofacial practice. The use of reference markers should be considered a standard procedure for the localization of radiopaque foreign bodies in the head and neck.
