Abstract

The aim of this retrospective study was to investigate etiology, clinical features, and treatment modalities of the mandibular condyle fracture in children and young adolescents. This study was conducted based on medical records and radiographic examinations of 44 pediatric patients. Patients received treatment under diagnosis of mandibular condylar fracture. They were divided into 4 groups according to their age. The involvement of condyle in the mandible fracture occurred in higher percentage in younger age groups. Falling was the most common etiologic factor in all age group, especially in children with age under 7. Condyle head was the most frequent site of fracture in age group of 4 - 7 whereas fracture tends to occur in lower condylar areas in older groups. In 54.5% of the mandibular condyle fracture, symphysis fracture was accompanied. Teeth injury occurred in higher incidency when condyle fracture accompanied symphysis fracture. Conservative treatments were applied to 43 out of 44 patients.

본 연구의 목적은 소아 청소년에서 발생한 하악 과두 골절의 빈도, 원인, 골절의 임상적 양상 및 치료 방법에 대한 후향적 분석을 통해 연령에 따른 하악 과두 골절의 임상적 특징 및 치료방법을 조사하는 것이었다. 최근 10년간 아주대학교 치과병원에서 하악 과두 골절로 진단받고 치료받은 만 15세 이하의 환자 44명을 대상으로 후향적 분석을 시행하였다. 하악골 골절 중 하악 과두 골절의 빈도는 환아의 연령이 어릴수록 높았다. 하악 과두 골절의 원인으로 넘어짐의 비율이 가장 높았다. 만 4 - 7세 군에선 과두부(condyle head) 골절이 91.7%를 차지하였으며, 연령이 증가할수록 과두경부(condyle neck) 골절 비율이 증가하였다. 하악 과두 골절 환아의 54.5%에서 하악 정중부 골절이 동반되었으며, 정중부 골절이 동반된 경우 구치부 치아 손상 빈도는 하악 과두 골절 단독인 경우에 비해 높았다. 44명 환아 중 43명에서 보존적 치료가 시행되었으며, 양측 과두의 심각한 골편 변위를 가진 1명 환아에서 관혈적 수술이 시행되었다. 본 연구 결과는 소아 청소년에서 발생한 하악 과두 골절의 진단 및 치료 계획 수립에 의미있는 자료로 적용될 수 있을 것이다.
