We report a case of long-term (about 10 years) limited mouth opening following a bilateral transtemporal approach for multiple cerebral aneurysms. A 41-year-old man with limited mouth opening was referred to our clinic for treatment. At the first visit, his maximum mouth opening distance was 13 mm between the upper and lower incisors and there were palpable indurations at the bilateral temporal muscles. We diagnosed this situation as a contracture of muscles, and performed bilateral coronoidectomy under general anesthesia. Mouth-opening exercises were started from one day postoperatively, and continued for 7 months. His maximum range of mouth opening is now maintained at 30 mm.

To assess whether patients were satisfied with the results of treatment, questionnaires were sent to 291 patients who had undergone orthognathic surgery for correction of jaw deformities and 133 questionnaires were returned with valid answers. The chief problem of 94 (71%) of these patients was appearance. Dysfunctions such as masticatory disturbance and speech difficulties were the primary reason for which 38 (29%) of the patients sought treatment. Seventy-five percent of the patients answered that they were satisfied with the results in regard to their chief problems. A favorable change in appearance was recognized by 125 patients, whereas five patients noticed no major changes and three patients were displeased with their postoperative faces. The patients'evaluations of their appearance seemed to be influenced by the responses of other peoPle to the surgical-results, and objective improvements did not always satisfy their expectations. Improvements in masticatory function and speech were recognized by 92 and 54 patients, respectively. Eighty patients had TMJ signs and symptoms such as click and/or pain before treatment, which disappeared in 53 (66%) of the symptomatic patients after the surgery. On the other hand, TMJ signs and symptoms appeared postoperatively in 7 (15%) of 47 patients without those before treatment. Psychologically, 42 patients noted favorable changes in personality after the surgery. Eight patients with mandibular set back noted the onset or worsening of snoring after the surgery.

This paper concerns a DC-DC converter control. In DC-DC converters, there exist both continuous components such as inductance, conductance and resistance and discrete ones, IGBT and MOSFET as semiconductor switching elements. Such a system can be regarded as a hybrid dynamical system. Thus, this paper presents a dc-dc control technique based on the model predictive control. Specifically, a case in which the load of the dc-dc converter changes from active to sleep is considered. In the case, a control method which makes the output voltage follow to the reference quickly in transition, and the switching frequency be constant in steady state. In addition, in applying the model predictive control to power electronics circuits, the switching characteristic of the device and the restriction condition for protection are also considered. The effectiveness of the proposed method is illustrated by comparing a conventional method through some simulation results.
