牙源性皮瘘病例报告及文献回顾

目的：通过病例分析，总结牙源性皮瘘的年龄分布及患牙位，为临床诊断、治疗及疗效评价提供依据。方法：展示6例牙源性皮肤瘘管的术前和术后面部和口内照片、X 线牙片，回顾以往报道的皮瘘病例60例，分析牙源性皮瘘的面部好发部位、及其对应的患牙位。结果：牙源性皮瘘主要好发在颊部、颏部、鼻旁和下颌下部4个部位，对应的患牙位分别是下颌第三磨牙、下颌切牙、上颌尖牙及下颌第一、第二磨牙，以下颌牙齿为主（71．2％）；相对于鼻旁和下颌下部皮肤瘘管好发于中老患者，颊部、颏部皮肤瘘管好发于年轻患者。对慢性牙周炎病灶牙进行根管治疗，拔除无需治疗的病灶牙，牙源性皮瘘均可痊愈。结论：对病灶牙的正确治疗是治疗牙源性皮瘘的主要方法。

Case report and literature review of dental original cutaneous sinus tract

Objective:To study the clinical characteristics of odontogenic cutaneous fistula.Methods:6 cases of odontogenic cutane-ous fistula were represented and the reports of 60 cases of the lesion were reviewed.Results:The fistula was mainly located in cheek, chin,para-nasal part,sub-mandibular area and the lower border of the mandible,and respectively corresponding to mandibular third molar,mandibular incisor,maxillary canine,mandibular first and second molar,the corresponding teeth were mainly in mandible (71 .2%).In middle and old aged patients the lesion usually in para-nasal or mandible area,In younger patients the lesion mostly loca-ted in cheek or sub-mandibular area.After root canal therapy for the teeth with apical periodontitis or extraction of none-curable teeth,the odontogenic cutaneous sinus tract disappeared.Conclusion:Proper treatment of focal teeth can cure the odontogenic cutaneous fistulas.
