Abstract：
To investigate the clinical characteristics of oral and maxillofacial tumors in children and adolescents.
This is a retrospective study of patients who had oral and maxillofacial tumors under the age of 18 years and were treated at the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology from January 1990 to July 2021 (31 y). Their general conditions, pathological diagnosis, gender, age, and anatomical location were counted to analyze their morbidity and composition characteristics.
This study contained 5405 cases, including 2903 male patients and 2502 female patients, with a median age of 9 years. Peak incidence was observed in the 14 to 18 years age group. The mandible (22.15%), maxilla (11.75%), and tongue (9.25%) were the most common sites of incidence. Malignant and intermediate type tumors accounted for 13.04%, benign tumors and tumor-like lesions for 55.67%, most often occurs in the maxillofacial bone, of which fibro-osseous lesions constitute an important part. Cysts accounted for 31.29%. Among the tumors occurring in the jaws, the most common malignant type was sarcoma, and ameloblastoma was the most common benign tumor. Malignant jaw tumors were mostly treated by resection, 10.64% by fibular flap reconstruction. While benign jaw tumors and tumor-like lesions were mostly treated by resection or curettage.
The distribution of anatomical location and pathological types of oral and maxillofacial tumors in children has certain characteristics, so that the selection of their treatment options is different from that of adults due to the consideration of the growth and developmental characteristics of children.

摘要：
目的：探讨儿童及青少年口腔颌面部肿瘤的临床特点。
方法：这是一项对18岁以下患有口腔颌面肿瘤并在口腔颌面外科接受治疗的患者的回顾性研究，北京大学口腔医院，1990年1月至2021年7月（31年）。他们的一般条件，病理诊断,性别,年龄,并对其解剖位置进行统计,分析其发病情况和组成特点。
结果：本研究包含5405例，包括2903名男性患者和2502名女性患者，平均年龄为9岁。在14至18岁年龄组观察到峰值发生率。下颌骨（22.15%），上颌骨（11.75%），舌头（9.25％）是最常见的发病部位。恶性和中间型肿瘤占13.04%,良性肿瘤和肿瘤样病变占55.67%,最常发生在颌面部骨，其中纤维骨性病变构成重要部分。囊肿占31.29%。在颌骨中发生的肿瘤中，最常见的恶性类型是肉瘤,成釉细胞瘤是最常见的良性肿瘤。恶性颌骨肿瘤主要通过切除治疗，10.64%由腓骨皮瓣重建。而良性颌骨肿瘤和肿瘤样病变主要通过切除或刮宫治疗。
结论：儿童口腔颌面部肿瘤解剖部位和病理类型的分布具有一定的特点，因此，由于考虑到儿童的成长和发育特征，他们的治疗方案的选择不同于成人。
