Treatment of mandibular fractures commonly involves the use of arch bars in temporary maxillo-mandibular fixation (also called intermaxillary fixation) to aid bone plating, for the postoperative application of light elastic traction to correct minor occlusal discrepancies and intermaxillary fixation for post reduction immobilisation. The purpose of this paper is to describe a quick and simple alternative for intermaxillary fixation.
Three cases of mandibular fractures are presented to demonstrate the use of intermaxillary screws instead of conventional arch-bar wiring.
Two cases were treated with closed reduction methods while the other case was treated with open reduction.
Subsequent fracture healing was not compromised using this technique.
With careful case selection, successful treatment outcome may be achieved using this time-saving and technically simple procedure. Some of the advantages and disadvantages of the intermaxillary screws are discussed.
下颌骨骨折的治疗通常包括在临时上颌-下颌固定(也称为颌间固定)中使用牙弓夹板以辅助接骨板固定,术后应用轻弹力牵引来纠正轻微的咬合差异以及进行颌间固定以维持复位后的固定。本文旨在描述一种快速简便的颌间固定替代方法。
展示三例下颌骨骨折病例,以说明使用颌间螺钉替代传统牙弓夹板结扎术的情况。
两例采用闭合复位法治疗,另一例采用切开复位法治疗。
采用该技术并未影响后续骨折愈合。
通过仔细选择病例,使用这种省时且技术简单的方法可取得成功的治疗效果。文中还讨论了颌间螺钉的一些优缺点。
