小児顎骨骨折22症例の臨床的検討 Clinical study of maxillofacial fractures on the pediatric 22 patients
We treated 22 pediatric patients (younger than 15 years old) with jaw fractures during the 13 years from 1986 to 1998. The following is our report on these cases.<BR>The yearly mean number of fractures is 1.7, and this number is decreasing. Classification by sex shows that patients in 13 cases were male and patients in 9 cases were female. Classification by age shows that patients who were 10 years old or older and younger than 15 years old were in the majority.<BR>There were four causes: traffic accidents (11 cases), falls (6 cases), sports accidents (3 cases) and violence (2 cases). Eight of the 11 traffic accidents were bicycle accidents. For patients who were younger than 10 years old, the main cause of the fracture was a fall. For patients who were 10 years old or older, a bicycle accident was the main cause.<BR>Most of the patients were referred patients; 11 cases were patients referred from other clnical institutes and 10 cases were referred from other departments of our hospital. Eighteen cases were hospitalized in our department, 3 cases were outpatients, and 1 patient was hospitalized in the orthopedics department of our hospital.<BR>As for the time when the patients received fractures, all fractures happened between 9 a. m. and 9 p. m., the period from noon to 3 p. m. being the peak time. As for the day of the week, fractures occurred mostly on Thursdays and Sundays. As for the month of the year, August and November were the months in which the most fractures occurred.<BR>All cases were mandible fractures. Twelve cases were mandibular body and / or mandibular angle fractures and 10 cases were condylar fractures.<BR>For mandibular body and / or mandibular angle fractures, we conducted open reduction in 8 cases, closed reduction in 3 cases and follow-up in 1 case. For condylar fractures, we conducted closed reduction in 9 cases and follow-up in 1 case. Open reduction was not conducted for condylar fractures.<BR>As for complications, facial laceration occurred in 9 cases, alveolar fractures in 4 cases, limb fractures in 3 cases, and tooth displacement in 2 cases.
