Intermaxillary fixation (IMF) carries an appreciable risk of occupational exposure to bloodborne viruses. Our aim was to establish the incidence and patterns of needlestick injuries during IMF at DAV Dental College. We surveyed 12 residents working in the Department of Maxillofacial Surgery for 1 year (December 2008 to December 2009) to find out how many injuries occurred during IMF. A total of 40 needlestick injuries were recorded during 172 IMF procedures (23%). Most injuries occurred in the maxillary left quadrant (n=16, 40%). Procedures done during the night had a much higher incidence (13/29, 45%) compared with 27/153 (18%) done during the day. Of the 40 injuries, 31 (78%) were recorded as superficial, the rest being deep. All injuries affected the non-working hand, and 39 (98%) were caused by a wire. Surgeons are at high risk of occupational exposure to bloodborne viruses from needlestick injuries during IMF. Detailed attention to the pattern of these injuries could help to develop improved strategies to minimise the incidence.
颌间固定（IMF）存在职业暴露于血源性病原体的显著风险。我们的目的是确定DAV牙科学院在进行颌间固定期间针刺伤的发生率和模式。我们对颌面外科12名住院医师进行了为期1年（2008年12月至2009年12月）的调查，以了解在颌间固定期间发生了多少例针刺伤。在172例颌间固定操作中，共记录到40例针刺伤（23%）。大多数损伤发生在上颌左象限（n = 16，40%）。夜间进行的操作发生率（13/29，45%）远高于白天进行的操作（27/153，18%）。在40例损伤中，31例（78%）记录为表浅损伤，其余为深部损伤。所有损伤均累及非优势手，39例（98%）由钢丝导致。在颌间固定期间，外科医生因针刺伤职业暴露于血源性病原体的风险很高。对这些损伤模式的详细关注有助于制定改进策略，以尽量降低发生率。
