ABSTRACT

Background:

Computer-aided design and manufacturing (CAD/CAM) is widely adopted for optimizing microsurgical reconstruction of mandibular defects. However, commercial solutions are hampered by costs and lengthy lead times, with the latter being problematic in cancer surgery. This study aimed to investigate the efficiency of an in-house CAD/CAM service for expeditious planning and execution of free fibula mandibular reconstruction in head and neck cancer patients.

Methods:

This retrospective cohort study compared cancer patients undergoing segmental mandibulectomy and immediate free fibula flap reconstruction treated before and after implementation of in-house CAD/CAM. The primary endpoint was treatment delay from preoperative consultation to surgery. Cases in the two groups were matched on the number of fibula segments required for mandibular reconstruction. The control group underwent segmental mandibulectomy and fibula flap reconstruction by "freehand." The CAD/CAM group underwent preoperative virtual surgical planning and CAD/CAM of intraoperative cutting guides for the mandibulectomy and fibula osteotomies. Outcomes were compared with the unpaired t test or Wilcoxon rank-sum test.

Results:

Sixteen patients were included in both groups. Treatment delay did not increase after implementation of in-house CAD/CAM with a median 6 (range 6-20) days wait in the CAD/CAM group and 8 (6-20) days wait in the control group (P = 0.48). Utilization of CAD/CAM significantly reduced fibula flap ischemia time with a mean of 18.4 [95% confidence interval 2.8; 33.9] minutes (P = 0.022).

Conclusions:

In-house CAD/CAM was implemented for free fibula flap mandibular reconstruction in head and neck cancer patients without causing treatment delay. Furthermore, CAD/CAM reduced fibula flap ischemia time.
