Development of Orthognathic Treatment for Dentofacial Deformities at Kushiro Red Cross Hospital : Cooperation with the Hospital and Clinic

This clinical study was performed in order to investigate the spectrum of dentofacial deformities, management, surgical outcomes and the living area of orthognathic patients treated at Kushiro Red Cross Hospital in the eastern part of Hokkaido. Fifty-three patients were treated for dentofacial deformities in our hospital from April 1989 to December 2004. These patients have increased in recent years. There were 13 male and 40 female patients. According to clinical diagnosis and operation procedure, mandibular prognathism was the most predominant diagnosis and only sagittal split ramus osteotomy was performed in most cases. The patients lived over a wide area of eastern Hokkaido. As Kushiro Red Cross Hospital cooperats with Hokkaido University Hospital and nearby dental clinics, patients could receive the greater part of orthognathic treatments in Kushiro Red Cross Hospital. However, most patients had to go to Hokkaido University Hospital a few times. Patients could benefit from developing orthognathic management at Kushiro Red thus Cross Hospital as well as at Hokkaido University Hospital.
