髁突囊内骨折常规术后加用(牙合)垫的临床疗效观察

Intracapsular condylar fracture of routine postoperative occlusal pad plus clinical observation

目的观察髁突囊内骨折常规术后加用(牙合)垫与不加用(牙合)垫二者之间的临床疗效。方法对32例髁突囊内骨折的患者分成2组,对照组常规手术:切开,复位,内固定术;观察组在常规手术:切开,复位,内固定术后,加用(牙合)垫。术后14 d均常规行张口训练。1、3、6月、1 a后定期随访。结果术后加用(牙合)垫的患者张口度正常,CT显示髁突骨质正常,无骨质吸收现象;而术后不加用(牙合)垫的患者张口度正常,CT显示一部分髁突表面扁平,有骨质吸收现象。结论髁突囊内骨折常规切开,复位,内固定术后,加用(牙合)垫髁突不会发生或减缓发生骨质吸收现象。

Objective To observe the intracapsular condylar fracture of conventional surgery after the addition of pads with and without occlusal splint with dental clinical efficacy between the two.Methods32 patients with intracapsular condylar fractures were divided into two group,a group of conventional surgery： incision,reduction,internal fixation;another group of conventional surgery： incision,reduction,internal fixation,plus dental splint.14 days after surgery were routinely mouth training.1 month,3 months,6 months,1 year after regular follow-up.Results after addition of occlusal pad normal mouth opening of patients,CT showed normal condylar bone,no bone absorption phenomenon;the use of dental surgery without splint in patients with normal mouth opening,CT shows part of the condylar surface flat,with bone resorption.Conclusionsintracapsular condylar fracture of conventional incision,reduction,internal fixation,plus pad condylar occlusion does not occur or mitigate the occurrence of bone absorption.
