For sufferers present process jaw reconstruction after surgical procedure for head and neck most cancers, computer-aided design and manufacturing (CAD/CAM) methods can enhance some key medical outcomes, experiences a research in Plastic and Reconstructive Surgical procedure.
“Our experience suggests that CAD/CAM techniques offer several benefits in patients undergoing free fibula reconstruction of the lower jaw, including a reduced risk of long-term complications requiring hardware removal,” feedback ASPS Member Surgeon Mario G. Solari, MD, of College of Pittsburgh.
CAD/CAM has ‘revolutionized’ jaw reconstruction—does it enhance affected person outcomes?
Over the previous decade, “[P]reoperative virtual surgical planning through CAD/CAM has revolutionized the way we approach head and neck reconstruction,” in keeping with the authors. Utilizing CAD/CAM expertise, surgeons can design and create “three-dimensionally printed, patient-specific cutting guides” in addition to pre-formed {hardware} to be used in reconstruction.
CAD/CAM has been efficiently utilized to “free fibula flap” reconstruction after surgical procedure for head and neck most cancers—utilizing bone and tissue grafts from the decrease leg to reconstruct the jaw.
“However, given the relatively recent introduction [of CAD/CAM], studies performing head-to-head comparison to the conventional technique are limited,” Dr. Solari and co-authors write. Their new research straight compares the short- and long-term outcomes of typical and CAD/CAM-assisted free fibula flap reconstruction.
The research included 215 sufferers present process free fibula reconstruction of the decrease jaw (mandible) between 2012 and 2021, primarily after most cancers surgical procedure. Of those, 136 sufferers had CAD/CAM-assisted reconstruction and 79 underwent typical reconstruction.
Improved effectivity and accuracy with CAD/CAM result in medical advantages
Sufferers present process CAD/CAM-assisted reconstruction spent much less time within the working room (OR)—about an hour lower than the traditional group. There was no vital distinction in hospital days.
Most short-term problems had been related between teams, together with return to the OR, main bleeding, blood clot-related problems, and charges of complete and full lack of the free fibula flap had been related as nicely. Nonetheless, the CAD/CAM group was much less prone to have dehiscence (reopening) of the incision web site: 7.4% versus 16.5%.
Evaluation of longer-term outcomes (two to 2.5 years) centered on 195 sufferers with no main problems within the first 30 days. Whereas most long-term problems had been related between teams, sufferers present process CAD/CAM-assisted reconstruction had been much less prone to want additional surgical procedure to take away the reconstruction {hardware}. After adjustment for potential threat elements, sufferers within the CAD/CAM group had been 60% much less prone to endure {hardware} elimination.
The discount in working room time displays “the lack of time-consuming hardware manipulations and bony adjustments” with typical free fibula flap reconstruction, the researchers write. Earlier research have reported elevated accuracy and stable bone fusion with CAD/CAM; these enhancements could result in a discount in long-term problems necessitating {hardware} elimination.
The research provides new proof that integrating CAD/CAM methods gives significant medical advantages for sufferers present process jaw reconstruction.
Dr. Solari and colleagues conclude, “Given the added cost with the use of CAD/CAM, future studies focusing on cost-effectiveness of this approach with respect to long-term outcomes and hardware maintenance will be important to justify the clinical significance of our results.”
