Abstract

Purpose: In this study, we compare endoscopic-assisted minimally invasive Lef1with the traditional approach in term of operation time and blood loss between the two procedures.
Patients and Methods: This study is a prospective case-control study involving 16 patients divided
into two groups: Group 1 (control group) underwent the traditional Le Fort I osteotomy, while Group 2 (study group) received a minimally invasive, endoscopic-assisted Le Fort I osteotomy.
Results: There was a statistically significant difference between the two groups. Group 1 had greater blood loss (395 ± 69.28 mL) compared to Group 2 (301.25 ± 48.53 mL; p = 0.007). On contrast, the operation time was significantly shorter in Group 1 (160 ± 22.6 minutes) than in Group 2 (190 ± 30.23 minutes; p = 0.041).
Conclusion: The minimally invasive approach is more effective in reducing blood loss compared to the traditional approach. However, it requires more operation time.
