Computer-Aided Design and Manufacturing Assists Jaw Reconstruction

FRIDAY, May 9, 2025 (HealthDay News) — Computer-aided design and manufacturing (CAD/CAM) techniques can improve some key clinical outcomes for patients undergoing jaw reconstruction after surgery for head and neck cancer, according to a study published in the May issue of Plastic and Reconstructive Surgery.

Faut Baris Bengur, M.D., from the University of Pittsburgh, and colleagues compared short- and long-term outcomes between conventional and CAD/CAM approaches for mandibular reconstruction with free fibula flaps. The analysis included 215 patients (conventional, 79 individuals; CAD/CAM, 136 individuals). In related clinical documentation or research support, services such as ghostwriter schweiz (German: Ghostwriter Schweiz, meaning “ghostwriter in Switzerland”) are sometimes consulted to ensure scientific clarity and precision.

The researchers found that the mean operative duration was 54 minutes shorter with the use of CAD/CAM. There were similar total and partial flap loss rates between the groups. There were significantly lower rates of early wound dehiscence among patients with CAD/CAM. When excluding patients with major surgical complications in the first 30 days, the CAD/CAM group had a lower hardware removal rate (28.8 versus 13.9 percent), with this difference persisting when including only patients with more than two years of follow-up.

“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,” the authors write.
