摘　　要：目的:探讨牙旁囊肿(paradental cyst,PC)的临床表现、影像学特征、治疗方法及预后情况,为明确诊断提供参考和依据。方法:回顾性分析2016年9月至2022年9月于山东大学口腔医院治疗的10例PC患者的临床资料,包括临床表现、影像学特征、病理学结果、治疗方法及预后情况。结果:10例PC患者中,男性8例,女性2例,平均年龄34.9岁。9例发生于下颌骨(5例累及48牙,4例累及38牙);1例发生于上颌骨(累及18牙)。有4例受累牙齿部分萌出,6例受累牙齿未萌出。7例患者表现为肿胀、疼痛等症状,3例无临床症状。所有患者均接受手术治疗,包括病变组织刮除术及相关牙齿拔除术。术后随访1~5年,均无复发。结论:PC主要好发于下颌第三磨牙区,影像学上呈现半月形边界清楚的透射影。肿胀疼痛是最常见的临床表现,手术治疗预后良好。Objective:To explore the clinical manifestation,imaging features,treatment methods,and prognostic characteristics of paradental cyst(PC),providing reference and basis for clear diagnosis.Methods:Retrospective analysis of clinical data of 10 patients with PC treated at the Hospital of Stomatology,Shandong University between September 2016 and September 2022 was performed,including clinical manifestations,imaging features,pathological results,treatment methods and prognosis.Results:Among the 10 patients with PC,8 were male and 2 were female,with an average age of 34.9 years.A total of nine cases occurred in the mandible(five cases involving 48 teeth,four cases involving 38 teeth);one case occurred in the maxilla,involving 18 teeth.Four cases had a partial eruption of affected teeth,while six cases had no eruption of affected teeth.Seven patients presented with symptoms such as swelling and pain,while three had no clinical symptoms.All patients underwent surgical treatment,including curettage of the lesion and extraction of relevant teeth.Follow-up for 1-5 years after surgery showed no recurrence.Conclusion:PC is a type of inflammatory root cyst that mainly occurs in the third molar area of the lower jaw.On imaging,it presents a clear crescent-shaped transmission shadow.Swelling and pain are the most common clinical manifestations,and the prognosis of surgical treatment is good.
