同侧上下颌骨单纯性骨囊肿1例报告及文献复习

Simple bone cyst in ipsilateral maxilla and mandible:A case report and literature review

目的:分析同侧上下颌骨单纯性骨囊肿(SBC)患者的临床表现、影像学特征、手术探查情况和病理学表现,以提高临床医生对该类疾病诊断和治疗的认识。方法:收集1例右侧上下颌骨SBC患者的临床资料、影像学特征、手术探查情况、病理学表现、临床诊断和治疗经过,并结合相关文献进行复习。结果:患者,男性,11岁;曲面断层检查,发现右侧上下颌骨内边界清楚的低密度影;无创伤史,就诊前无自觉症状和面部不对称;专科检查未见任何阳性体征;结合手术探查情况及病理学诊断确诊为右侧上下颌骨SBC;采用传统刮治术治疗,术后患者恢复良好,无明显不适。术后6个月随访,患者口内创口愈合良好,无红肿;锥形束计算机断层扫描(CBCT)影像检查结果显示骨腔变小,骨腔内可见新生骨小梁,成骨情况良好,目前患者处于定期随访中。结论:同侧上下颌骨SBC无特征性的临床表现和影像学表现,极易与颌骨常见的疾病混淆。需结合影像学检查、手术探查情况和病理学检查最终确诊。

Objective:To analyze the clinical presentations,radiographic features,operative findings,and pathological characteristics of one patients with unilateral maxillary and mandibular simple bone cysts(SBC),and to enhance the clinicians’recognition and treatment of this condition.Methods:The clinical data,radiographic features,operative findings,pathological characteristics,clinical diagnosis,and treatment of a case with right-sided maxillary and mandibular SBC were collected,and the relevant literatures were reviewed.Results:The patient,an 11-year-old male,presented with a clearly demarcated low-density image within the right maxillary and mandibular bones on panoramic tomography.There was no history of trauma,no subjective symptoms or facial asymmetry before treatment,and no positive signs of the specialist examination.The patient was diagnosed with right-sided maxillary and mandibular SBC based on the operative exploration and pathological diagnosis.The patient received the conventional curettage treatment and recovered well postoperatively without significant discomfort.A 6-month follow-up results showed good intraoral wound healing without swelling.The cone beam computed tomography(CBCT)results showed a smaller bone cavity with visible new bone trabeculae,indicating good osteogenesis.The patient was currently the under regular follow-up.Conclusion:Unilateral maxillary and mandibular SBC do not present with characteristic clinical signs and radiographic features,which can be easily confused with the common maxillofacial diseases.A definitive diagnosis should be made by combining radiographic examination with surgical and pathological findings.
