Mandible is one of the commonly fractured bone in children during maxillofacial trauma. These factures are usually managed conservatively but sometimes require open reduction and internal fixation (ORIF). Management of mandibular fracture in children is influenced by the presence of developing permanent tooth buds, minimal anchorage from primary teeth and facial growth and development. Although, there have been technical and material advancements with ORIF, it is still associated with complications related to growth and damage to developing teeth. This case report describes a case of mandibular parasymphyseal fracture managed successfully with open reduction and internal fixation using a miniplate and a consequent cessation of root growth and eruption failure of a mandibular canine present in the fixation area.
下颌骨是儿童颌面创伤中常见的骨折部位之一。这些骨折通常采用保守治疗，但有时需要切开复位内固定（ORIF）。儿童下颌骨骨折的治疗受到恒牙胚发育、乳牙提供的锚固力极小以及面部生长发育的影响。尽管切开复位内固定技术和材料有了进步，但它仍与生长相关的并发症以及对发育中牙齿的损伤有关。本病例报告描述了一例下颌骨正中旁骨折，采用微型钢板切开复位内固定成功治疗，随后固定区域内的下颌尖牙牙根生长停止且萌出失败。
