This single-arm clinical trial evaluated the intraoral approach (IOA) for segmental mandibulectomy and fibular free flap (FFF) reconstruction in 7 patients with benign mandibular lesions. The study found that the IOA resulted in significantly lower Patient and Observer Scar Assessment Scale (POSAS) scores compared to the extraoral approach (EOA) group, indicating better scar outcomes and higher patient satisfaction.
Key findings
- All 7 patients successfully completed FFF microvascular reconstruction through IOA without serious complications.
- The POSAS score for the IOA group was significantly lower than that of the EOA group one year postoperatively.
- Operative time was significantly longer for the IOA compared to the EOA (p=0.002).
Why it matters
The findings suggest that the intraoral approach for fibular flap reconstruction may enhance aesthetic and functional outcomes for patients undergoing segmental mandibulectomy, which is crucial for improving quality of life post-surgery.
