Resumé

Background: When surgeons operate under general anesthesia, length of surgery, not only its outcome, matters. In maxillofacial surgery we can reduce the time in reconstructive surgery by using presurgical bended plates in presurgically designed 3D models.

Method: The study measured the mean time to bend the plates preoperatively on a printed three-dimensional model and the capability of the plates to adapt well on the mandible intraoperatively in cases of mandibular reconstruction after partial resection of the mandible due to pathology, such as benign aggressive tumors.

Results and conclusions: The mean time to bend the plates preoperatively was 17 minutes, with rapid adaptation during surgery. This is important in minimizing the time that the wound is exposed to the environment and minimizes the trauma to the surrounding soft tissues. Multiple checks of the plate if bended at time of surgery can increase trauma to the surrounding soft tissues.

The study supports the recommendation of the use of the preoperatively corrected and printed 3D models to prebend the plates pre-operatively. This step should be included as a routine workflow in elective cases, since it is not be possible in cases of emergency or urgency.
