Summary
This study compared midline and paramidline mandibulotomies for oral cancer surgery. Both approaches showed similar complication rates, but paramidline mandibulotomy may offer better function preservation.
Area of Science:
- Oral and Maxillofacial Surgery
- Surgical Oncology
Background:
- Mandibulotomy is a critical surgical technique for accessing oral cavity and oropharyngeal cancers.
- Evaluating complications of different mandibulotomy types is essential for optimizing patient outcomes.
Purpose of the Study:
- To compare complication rates between midline and paramidline mandibulotomies.
- To assess the functional preservation offered by each surgical approach.
Main Methods:
- A retrospective review of 42 patients undergoing mandibulotomy for oral or oropharyngeal cancer.
- Patients were divided into midline (19) and paramidline (23) groups.
- Preoperative panoramic films were used for mandibular evaluation.
Main Results:
- Overall, 47.6% of patients experienced mandibulotomy-related complications (9 minor, 11 major).
- Midline mandibulotomy had 6 major and 4 minor complications.
- Paramidline mandibulotomy had 5 major and 5 minor complications.
Conclusions:
- No significant difference in complication rates was found between midline and paramidline mandibulotomies.
- Paramidline mandibulotomy, by preserving geniohyoid and genioglossus muscles, is suggested as a superior function-preserving option.
