Abstract
Background: Current methods utilize virtual surgical planning sessions and custom plate milling via 3rd party vendors, which is costly and time consuming negating the effectiveness in acute facial trauma.
Objectives: To demonstrate a state-of-the-art method of in-house computer-aided design, 3D printing and custom plate adaptation for acute mandibular trauma.
Methods: An analysis of an ongoing study that includes 5 patients was completed. All patients had acute mandible fractures and were treated with the same method. This method used the CT scan acquired during the patients ER presentation and was loaded into FDA approved software (Meshmixer and Materialise). The CT scan was segmented and virtually reduced in-house by a surgeon/radiologist team. The virtually reduced mandible was printed in expedited fashion using the NewPro 3D printer. Reconstruction plates were pre-bent to the virtually reduced 3D printed mandible and sterilized prior to surgery. Data was recorded and analyzed from the pre-surgery and surgical stage.
Findings: Our cohort had a mean age of 49 (39–58). There were 4 bilateral mandible and 2 unilateral fractures. Average Pre-surgery VSP, printing, plate bending and operative time was 21.2 ± 2.51, 90.7 ± 3.5, 12.5 ± 4.94, 108.3 ± 49.9 minutes, respectfully. OR time for 10 randomly selected traditionally completed comparable cases was 154 ± 35.5 minutes. There is statistical significance (p = 0.0207) when comparing OR time means. Post-operative CT scans from the experimental group and the randomly selected traditional group were blinded and reviewed independently by a senior surgeon and subsequently categorized into either ideal or adequate. The results of the experimental group were 4 ideal and 1 adequate and the traditional group had 2 ideal and 8 adequate (chi-square, p = 0.025).
Conclusion: This method of in house virtual reduction, 3D printing, and pre-surgery plate bending yields faster operative time and higher quality reductions compared to traditional surgery. To our knowledge, this is the first report to describe such a protocol.
