Summary
The facial-submental island flap (FSIF) offers a safe and effective method for reconstructing nasopharyngeal defects after radionecrosis. This study shows reliable flap survival and good functional outcomes in 10 patients.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Plastic Surgery
Background:
- Nasopharyngeal radionecrosis presents significant reconstruction challenges.
- Endoscopic debridement is a key step in managing these defects.
- The facial-submental island flap (FSIF) is explored as a reconstructive option.
Purpose of the Study:
- To evaluate the feasibility and efficacy of FSIF for nasopharyngeal defects post-radionecrosis.
- To assess flap survival and functional outcomes in a patient cohort.
Main Methods:
- Retrospective analysis of 10 male patients with nasopharyngeal radionecrosis.
- Patients underwent endoscopic debridement followed by immediate FSIF reconstruction.
- Data collected on procedure duration, blood loss, flap dimensions, and complications.
Main Results:
- All 10 FSIFs demonstrated complete survival.
- Average procedure time was 6.7 hours with 110 mL blood loss.
- No major complications or recurrences observed during 6-12 month follow-up.
- Favorable functional outcomes including patent airways and acceptable speech.
Conclusions:
- FSIF is a safe and effective reconstructive alternative for nasopharyngeal radionecrosis.
- It offers advantages, especially when microvascular free flaps are difficult.
- The technique shows reliable flap survival and good functional results.
