Summary
Predicting mandibular invasion in oral cancer patients is crucial. Orthopantomograms accurately identify bony involvement, guiding surgical decisions for better patient outcomes.
Area of Science:
- Oral oncology
- Head and neck surgery
- Radiology
Background:
- Mandibular resection for oral cancers causes significant aesthetic and functional deficits.
- Accurate preoperative assessment of mandibular invasion is essential for planning surgical extent.
Purpose of the Study:
- To evaluate the reliability of orthopantomograms as a preoperative predictor of mandibular invasion in oral cancer patients.
Main Methods:
- Retrospective analysis of orthopantomograms in patients with oral cancer.
- Correlation of radiographic findings with surgical and histopathological results.
Main Results:
- Orthopantomograms demonstrated high accuracy in predicting bony involvement.
- Accuracy was reduced for central arch lesions.
- The utility of outer table rim mandibulectomy requires further investigation.
Conclusions:
- Orthopantomograms are a cost-effective and reliable tool for assessing mandibular invasion in most oral cancer cases.
- Careful consideration is needed for central arch lesions and the feasibility of limited resections.
