The use of in-house patient-specific 3D printed models in plastic-, orthopedic and neurosurgical planning: a preliminary report

Aim: A limited number of studies have attempted to quantify the advantages of using in-house 3D printed models. We designed a pilot study to assess the value of in-house production of patient-specific 3D-printed models in pre-surgical planning. Methods: A 12-question survey was designed and sent to surgeons to assess any purported benefits of 3D-printed anatomic models. In-house 3D model printing was completed on a Stratasys J750 Polyjet printer. Each 3D printed model was delivered to the supervising surgeon days before the procedure for final validation. The 3D models were subsequently utilized in the operating room. Results: A total of 50 surveys were completed for a response rate of 100%. Approximately 94% of the participants strongly agreed that the 3D-printed model was a valuable clinical tool for pre-surgical planning. The majority of the respondents (78%) reported improved surgical efficiency. Conclusion: 3D models is a valuable tool for surgical planning.
