The aim of the present study was to evaluate the accuracy of a novel simulation software package (OrthoForecast) for predicting the soft tissue profile after orthognathic surgery. The study included 15 patients with facial asymmetry (asymmetry group), 15 with a skeletal class II jaw relationship (class II group), and 15 with a skeletal class III jaw relationship (class III group). Twenty-four feature points were digitized, and the distances between points on the predicted and actual postoperative images were compared. Thirty-seven calibrated evaluators also graded the similarity of the predicted images compared to the actual postoperative photographs. Comparisons between the predicted and actual postoperative images revealed that the mean difference between feature points was 3.1 ± 1.4 mm for the frontal images and 2.9 ± 0.8 mm for the lateral images in the asymmetry group; 2.7 ± 0.9 and 2.1 ± 1.6 mm, respectively, in the class II group; and 1.8 ± 1.2 and 1.7 ± 1.0 mm, respectively, in the class III group. More than half of the evaluators assessed the predicted images as similar to the actual postoperative images in all groups. In conclusion, OrthoForecast can be regarded as useful, accurate, and reliable software to predict soft tissue changes after orthognathic surgery. © 2014 International Association of Oral and Maxillofacial Surgeons.

A 76-year-old Japanese female with type 2 diabetes was admitted to our hospital with impaired consciousness and hyperglycemia. She was under treatment with glimepiride and voglibose. On admission, she presented with confusion and sensory aphasia. Her HbAlc level was 12.8 %, and her random plasma glucose level was 330 mg/d/. Magnetic resonance (MR) imaging and MR venography showed a left transverse sinus thrombosis. Anticoagulant therapy was administered, the patient was rehydrated and insulin was administered. The sensory aphasia improved three days after admission, and did not recur thereafter. Dehydration, abnormal hemostasis and decreased fibrinolytic activity due to chronic hyperglycemia could have caused the cerebral venous thrombosis. Inspection of MR images acquired at a later stage showed hypoplasia of the left transverse venous sinus, and the thrombus was thought to have formed in this region. When patients with poorly controlled diabetes mellitus present with neuropsychiatric symptoms, then the possible occurrence of transverse sinus thrombosis should be considered.
