For patients who undergo the jaw reconstruction after surgery for head and nack cancer, computer AID design and production (CAD/CAM) techniques Plastic and reconstructive surgeryThe official medical magazine of the American Society of Plastic Surgeons (ASPS).
“Our experience suggests that CAD/CAM techniques offer different benefits in patients who undergo a free Fibula reconstruction of the Lower Kaak, including a reduced risk of long-term complications that are re-realizing hardware,” says ASPS member in a relaxation.
CAD/CAM Has ‘Revolutingod’ Jav -reconstruction – does it improve the results of the patient?
In the past decade, “[P]Virtual reooperative surgical planning Thruh CAD/CAM has brought about a revolution in the way we approach head and neck reconstruction, “according to the authors. With the help of CAD/CAM technology, surgeons can be” three-dimensional pre-report hardware for reconstruction.
CAD/CAM has been successfully applied to the reconstruction of “Free Fibula Flap” after the operation for main and neck cancer, using bone and tissue transplates of the lower leg to reconstruct the jaw. “Given the relatly recent introduction, however [of CAD/CAM]Studies that perform head-to-head comparison with conventional technology are limited, “write Solari and co-authors.
Their new study immediately compares the short and long-term results of conventional and CAD/CAM-ASPETED Free Fibula Flap reconstruction.
The study included 215 patients who underwent a free fibula reconstruction of the lower jaw (lower jaw) between 2012 and 2021, mainly after cancer surgery. Of these, 136 patients had CAD/Cam-asseted reconstruction and 79 underwent conventional reconstruction.
Improved efficiency and accuracy with CAD/CAM lead to clinical benefits
Patients who underwent CAD/Cam-asseted reconstruction spent less time in the operating room (or)-an hour less than the conventional group. There was no difference in meaning in hospital days.
Most of the short -term complications were comparable between groups, including return to the OR, large bleeding, blood clot -related complications and the total and complete loss of the free fibula flap were also comparable. The CAD/CAM group, however, had less chance of dehiscence (reopening) of the Incision site: 7.4% versus 16.5%.
Analysis of results in the longer term (2 to 2.5 years) was aimed at 195 patients without major complications in the first 30 days. Although most long-term complications were comparable between groups, patients who had CAD/Cam-asseted reconstruction were less likely to need further operation to remove the reconstruction hardware. After correction for a potential risk factor, patients in the CAD/CAM group had 60% less chance of removal hardware.
The reduction in operating room time reflects “the lack of time-consuming hardware manipulations and bony adjustments” with conventional free fibula flap reconstruction, the researchers write. Previous studies have reported built -in accuracy and fixed bone fusion with CAD/CAM; This improvement can lead to a reduction in the removal of long -term complications in need of removal.
The study adds new evidence that the integration of CAD/CAM techniques offers meaningful clinical benefits for patients who undergo the jaw reconstruction. Solari and colleagues conclude: “Given the added costs with the use of CAD/CAM, future studies aimed at the cost-effectiveness of this approach with regard to long-term results and hardware maintenance will be important to justify the clinical meaning of our results.”
