Pathological fracture of the mandible caused by radicular cyst is rare. This report describes a unique case of a mandibular pathological fracture caused by radicular cyst, arising from an endodontically treated molar.
A 49-year-old female was referred to our department with persistent pain in left mandibular angle, accompanying with restricted mouth opening and malocclusion.
An orthopantomograph (OPG) showed a unilocular lesion with a relatively well-defined border, and the lesion was associated with a fracture in the inferior border of the mandible.
This patient was treated through curettage of the cyst combined with open reduction and internal fixation of the fracture.
At the 1-year follow-up visit, the patient did not have any complaints, and the radiographs indicated the consolidation of the fracture without recurrence of cyst.
This case report highlights the routine follow-up of endodontically treated teeth in order to check for apical healing and detect the cystic change at early stages.
由根端囊肿引起的下颌骨病理性骨折较为罕见。本报告描述了一例由根端囊肿导致的下颌骨病理性骨折的独特病例，该囊肿源于一颗接受过根管治疗的磨牙。
一名49岁女性因左下颌角持续疼痛、伴有张口受限和咬合不正被转诊至我科。
全景曲面断层片（OPG）显示一个边界相对清晰的单房性病变，且该病变与下颌骨下缘骨折相关。
该患者接受了囊肿刮除术，并结合骨折切开复位内固定术进行治疗。
在1年的随访中，患者无任何不适主诉，影像学检查显示骨折愈合且囊肿未复发。
本病例报告强调了对接受过根管治疗的牙齿进行常规随访的重要性，以便检查根尖愈合情况并早期发现囊性病变。
