Abstract Objectives Mandibular reconstruction after segmental mandibulectomy can be challenging without virtual surgical planning and osteotomy guides. The purpose of this study was to analyze anatomic parameters facilitate the evaluation ideal fibula wedge osteotomies reconstruct neomandibula in a simple cost-effective manner need for preoperative planning. Materials methods Computed tomography scans were acquired from randomly selected patients, all images obtained routine clinical diagnostics, e.g., tumor staging, or preoperatively before reconstruction. Data used calculate stereolithographic models mandible length angle measurements. Statistical analysis performed ( p < 0.05). Results CT 100 patients analyzed: 39 female 61 male mean age 59.08a. mandibular arch proved constant with 241.07 ± 2.39°. outside B-segment 80.05 5.16 mm; anterior S-segment 27.69 3.16 mm. showed differences means = 0.004) between groups, but effect low. No relevant statistical significances detected. Conclusions development template tool would benefit majority head neck which is due symphysis segment throughout general patient population, allowing mimicking harmonic up three segments. Clinical relevance developed necessary an providing novel approach cost-effective.
