牙源性面部瘘管临床治疗探讨

Clinic Anylisis for Odontogenic Fistule

牙源性面部瘘管的常规治疗是手术切除瘘管和拔除患牙，但因失牙而影响咀嚼功能．其保守治疗是根管治疗加瘘管切除，然而复发率很高．本研究对３４例非智齿性牙源性面部瘘管进行改进保守治疗，其中２５例采用瘘管和根端切除或瘘管和患牙髓底及牙槽纵隔切除，并植入羟基磷灰石颗粒．另９例仅作根管治疗加瘘管切除．术后１，３，６，１２个月复诊，观察瘘管有无复发和患牙稳固情况，经临床和Ｘ线检查，前者有很大的优越性．

Endodontic treatment and operation had been the primary therapy for odontogenic fistule with remaining teeth.But the rates of recurrence were very high.In this study,34 cases of non-odontogenic ficial fistule(not resulting from impacted third molar)were treated with two methods.25 cases(group one)were treated with fistule and tooth apical resection,or fistule and pulp chamber floor and alveoli septum resection before the implantation of hydroxyaptite(HA).9 cases(group two)received endodontic treatment and fistule and fistule removel.The follow-up data including recurrence of fistule and mobility of teeth were collected at 1,3,6,12 months,Assessment criteria were based on clinic and X-rays examination.The results indicate that tretreatment of the former is better than that of the later.
