Popis:	AIM To assess treatment outcome and 1-year stability of LeFort I advancement in patients with complete cleft lip and palate. METHODS Thirty-five patients (age 20.65 ± 2.20 years) with unilateral (n = 25) or bilateral (n = 10) complete cleft lip and palate who underwent LeFort I advancement were included.Lateral cephalograms before surgery (T1), immediately postsurgery (T2), and at 1-year follow-up (T3) were superimposed, and the position of anterior nasal spine (ANS), A-point, and U1 Tip assessed using an x, y coordinate system. Differences between landmark positions at the 3-time points were analyzed using paired sample t-tests, with a significance defined as α ≤ 0.05. RESULTS The mean surgical advancement in the horizontal direction (T2-T1) was 6.50 ± 2.62 mm at ANS (P
