Mandibular Injuries
Conditions
Brief summary
In mandibular reconstruction, computer-assisted procedures, including virtual surgical planning (VSP) and Custom-made implants, have become an integral part of routine clinical practice. Especially complex cases with extensive defects after ablative tumor surgery benefit from a computer-assisted approach. Various CAD/ CAM-manufactured tools such as surgical guides (guides for osteotomy, resection and predrilling) support the transition from virtual planning to surgery. Custom made implants are of particular value as they facilitate both osteosynthesis and the positioning of bone elements. Computer-based approaches may be associated with higher accuracy, efficiency, and superior patient outcomes. However, certain limitations should be considered, such as additional costs or restricted availability. In the future, automation of the planning process and augmented reality techniques, as well as MRI as a nonionizing imaging modality, have the potential to further improve the digital workflow.
Interventions
PROCEDUREustom made plate and split rib bundle bone graft using virtual surgical planning
the operation will be done through a combined intra-oral lower sulcus and extra-oral extended submandibular incisions for lateral mandibular resections and a combined intraoral lower sulcus and transverse collar incision for midline mandibular resections.

Inclusion criteria
* Benign mandibular tumors planned to be managed by segmental mandibulectomy. * Adequate soft tissue coverage after mandibular resection.
Exclusion criteria
* Patients not suitable for general anesthesia because of severe systemic medical problems, * Soft Tissue deficiency after resection, which are better treated by free osseo-cutaneous flaps. * Planning to have postoperative radiotherapy or with history of head and neck radiotherapy. * Obvious preoperative infections at the site of surgical resection. * Recurrent lesions where wider resection will necessitate free composite flap reconstruction
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Wound healing | 2 weeks | patients will be scored yes if healed and no for not healed wounds |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Aesthetic deformity | 4 weeks | patients will be scored yes for presecne of aesthetic deformity and no for absence of deformity |
| Patient satisfaction | 3 days | The level of patient satisfaction will be measured using five-point Likert scale (1 = very dissatisfied, 2 = dissatisfied, 3 = neutral, 4 = satisfied, and 5 = very satisfied |
