Clinical cases of cysts of the jaw treated in the Department of Oral Surgery of our university during the 10 y between 1980 and 1989 were studied clinically. Patients with radicular cyst, dentigerous cyst, odontogenic keratocyst and postoperative maxillary cyst, which were found at relatively high frequencies, were further analyzed with regard to age, sex and anatomical distribution. A diagnosis of cyst was established in 1,444 patients during the above period, and 1,234 (85.5%) of them had cysts of the jaw. According to a pathological classification by Ishikawa's method, these patients included 509 (41.2%) with radicular cyst, 259 (27.0%) with dentigerous cyst, 95 (7.7%) with odontogenic keratocyst and 267 (21.6%) with postoperative maxillary cyst. The pattern of age distribution in cases of radicular cyst, odontogenic keratocyst and postoperative maxillary cyst was similar to that found in previous studies. Among patients with dentigerous cyst, those aged under 20 y accounted for about 60%. Radicular cyst occurred most frequently in the maxillary lateral incisors, dentigerous cyst in the mandibular wisdom teeth, and odontogenic keratocyst in the region between the mandibular molar and the ramus of the mandible.
对我校口腔外科在1980年至1989年这10年间治疗的颌骨囊肿临床病例进行了临床研究。对发病率相对较高的根端囊肿、含牙囊肿、牙源性角化囊肿和上颌术后囊肿患者，进一步分析其年龄、性别和解剖分布情况。在上述期间，1444例患者确诊为囊肿，其中1234例（85.5%）患有颌骨囊肿。根据石川法进行病理分类，这些患者包括509例（41.2%）根端囊肿、259例（27.0%）含牙囊肿、95例（7.7%）牙源性角化囊肿和267例（21.6%）上颌术后囊肿。根端囊肿、牙源性角化囊肿和上颌术后囊肿的年龄分布模式与以往研究相似。在含牙囊肿患者中，20岁以下者约占60%。根端囊肿最常见于上颌侧切牙，含牙囊肿多见于下颌智齿，牙源性角化囊肿多见于下颌磨牙与下颌升支之间区域。
