To determine the incidence of bur breakage in routine orthognathic surgery, as well as its postsurgical sequela, and to illustrate 2 cases with more than 6 months' follow-up.
We performed a retrospective evaluation of case records of 76 consecutive orthognathic surgical procedures performed by a team of 2 surgeons over a period of 16 months, between January 2009 and July 2010, at a single center.
Surgical bur breakage was reported in 5 patients in the series. Of these, 3 were retrieved whereas 2 were not, 1 of which caused a foreign body reaction in the patient, which persisted for a duration of almost 1 year.
Instrument breakage may be a relatively common occurrence with the use of surgical burs in orthognathic surgery but its incidence is seldom recorded or reported. This study gives insight into the probability of postoperative sequela of these instruments when left in situ and a protocol for management of broken instruments.
确定常规正颌外科手术中车针折断的发生率及其术后后遗症，并举例说明2例随访超过6个月的病例。
我们对2009年1月至2010年7月期间在单一中心由一组2名外科医生在16个月内连续进行的76例正颌外科手术的病例记录进行了回顾性评估。
该系列中有5例患者报告了手术车针折断。其中，3枚被取出，2枚未取出，其中1枚在患者体内引起了异物反应，持续了近1年。
在正颌外科手术中使用手术车针时，器械折断可能是一种相对常见的情况，但其发生率很少被记录或报告。本研究深入探讨了这些器械留在原位时术后出现后遗症的可能性以及折断器械的处理方案。
