A Novel Approach to Virtual Surgical Planning for Mandibular and Midfacial Reconstruction With a Fibula Free Flap.

[BACKGROUND] The fibula free flap is a major workhorse in facial reconstruction. To decrease operative times, virtual surgical planning (VSP) has been implemented. Traditional VSP is costly and may delay operative planning. in this study, the authors present a novel algorithm using readily accessible software packages to perform VSP in a manner that is quick and cost-effective.

[METHODS] A 6-part survey was administered to physicians with prior training in facial reconstruction. Fourteen physicians participated regarding outcomes on 10 patients who underwent mandibular or midfacial fibula free flap reconstruction. Participants were asked to match the true postoperative and VSP models and rate the similarity of the models using the Likert scale (0-10). The goal was to determine whether the VSP models accurately depicted the actual reconstruction, and whether they would use VSP in future clinical practice.

[RESULTS] The physicians surveyed were able to match the models correctly 93.6% of the time. The mean score for the similarity between virtual and actual models ranged between 7.60 and 8.80. Most participants (90.9%) who answered stated they would use our VSP algorithm if they were trained in the protocol.

[CONCLUSIONS AND RELEVANCE] Virtual surgical planning models were created utilizing our novel algorithm. Participants matched the preoperative VSP plan with the postoperative model most of the time and rated the similarity well. Participants in our study are interested in learning more about physician performed VSP. The authors believe this model may be financially and clinically relevant and serve as an excellent educational tool.
