Summary
Infrastructure maxillectomy effectively treats lower maxillary sinus and hard palate neoplasms with acceptable outcomes. Postoperative radiotherapy or chemoradiotherapy may reduce recurrence rates in these patients.
Area of Science:
- Oral and Maxillofacial Surgery
- Surgical Oncology
- Head and Neck Cancer
Background:
- Infrastructure maxillectomy involves removing the lower maxilla and hard palate.
- Neoplasms of the maxillary sinus and hard palate require surgical intervention.
- Assessing outcomes of this specific surgical procedure is crucial for treatment planning.
Purpose of the Study:
- To analyze clinical data and treatment outcomes of patients undergoing infrastructure maxillectomy.
- To evaluate the efficacy of infrastructure maxillectomy for maxillary sinus and hard palate neoplasms.
- To identify factors influencing survival and recurrence rates.
Main Methods:
- Retrospective analysis of 13 patients who underwent infrastructure maxillectomy between 2011 and 2019.
- Patients were categorized into maxillary sinus neoplasm (n=5) and hard palate neoplasm (n=8) groups.
- Surgical approaches, reconstruction methods, and adjuvant therapies (radiotherapy, chemotherapy) were documented.
Main Results:
- Overall survival rate was 61.5% (8/13) and recurrence rate was 46.2% (6/13).
- The sublabial approach was most common; reconstruction involved obturators, skin grafts, and free flaps.
- Adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT) was administered post-surgery.
Conclusions:
- Infrastructure maxillectomy appears effective for lower maxillary sinus and hard palate neoplasms, with minimal functional or cosmetic morbidity.
- Postoperative RT or CCRT may be beneficial in reducing recurrence rates.
- Further research can optimize management strategies for these complex cases.
