Summary
The mandibular swing procedure is feasible for patients with upper aerodigestive tract cancers, even after radical preoperative radiotherapy. Complication rates were similar between irradiated and non-irradiated groups, with all patients achieving oral rehabilitation.
Area of Science:
- Surgical Oncology
- Head and Neck Surgery
- Radiation Oncology
Background:
- The mandibular swing approach is increasingly used for upper aerodigestive tract malignancies.
- Limited data exists on its feasibility in patients pretreated with radical radiotherapy.
- Previous findings suggested feasibility, necessitating further investigation.
Purpose of the Study:
- To evaluate the feasibility and complication rates of the mandibular swing procedure in patients who have undergone radical preoperative radiotherapy.
- To update previous findings with a larger patient cohort.
Main Methods:
- Retrospective analysis of 44 patients undergoing mandibular swing.
- Comparison of complication rates between patients who received radical preoperative radiotherapy and those who did not.
- Assessment of oral rehabilitation outcomes.
Main Results:
- 50% of patients received radical preoperative radiotherapy to fields including the osteotomy site.
- No statistically significant differences in complication rates were observed between irradiated and non-irradiated groups.
- All patients in the study were successfully orally rehabilitated.
Conclusions:
- The mandibular swing procedure is a viable option for upper aerodigestive tract cancer patients, irrespective of prior radical radiotherapy.
- Preoperative radiotherapy does not significantly increase complication rates for this surgical approach.
- Successful oral rehabilitation is achievable in all patients undergoing this procedure.
