## 3 Results  
A comparison of the results obtained in the cleft lip and palate group and the cleft lip group for SNA, SNB, and ANB parameters is presented in Table 1. It was observed that a statistically significant higher degree of maxillary prognathism (SNA) occurred in the cleft lip group (\(\overline{\alpha}\) = 82.9 degrees; SD = 4.0 degrees) than in the cleft lip and palate group (\(\overline{\alpha}\) = 79.1 degrees; SD = 4.0 degrees) (\(p\) < 0.001). In addition, there were statistically significant differences in mandibular versus maxillary (ANB) position between the study groups (\(p\) = 0.008). The mean ANB score for the lip and palate group was 2.13 degrees (SD = 2.7 degrees) and for the lip group was 4.03 degrees (SD = 2.7 degrees) (Table 1). Table 2 presents the comparison of FMA, Gonali angle, APDI, and ODI scores between the study groups. Statistically significant differences were observed for the ODI parameter (\(p\) = 0.046), with the cleft lip and palate group having a mean score of 74.0 points (SD = 8.8 points) and the cleft lip group having a mean score of 78.2 points (SD = 7.0 points) (Table 2). Otherwise, no statistically significant differences were observed. A comparison of IMPA, U1 to NA (mm), U1 to NA (deg), L1 to NB (mm), and L1 to NB (deg) scores relative to the study groups is presented in Table 3. Statistically significant differences were observed for the IMPA parameter (\(p\) = 0.001), the mean score for the cleft lip and palate group was 88.2 points (SD = 7.9 points), and for the cleft lip group the mean score was 94.7 points (SD = 6.8 points). Additionally, statistically significant differences were observed for the parameter L1 to LOP (\(p\) = 0.004), the mean score in this case for the cleft lip and palate group was 72.8 points (SD = 7.8 points) and for the cleft lip group the mean was 67.3 points (SD = 6.3 points). The results were statistically significantly different for the parameter L1 to NB (deg) (\(p\) = 0.004), the mean score for the cleft lip and palate group was 18.1 deg (SD = 6.6 deg) and for the cleft lip group the mean score was \begin{table}

Table 1: Comparison of SNA, SNB, and ANB scores between cleft lip and palate and cleft lip groups. 23.1 deg (SD = 6.5 deg). Otherwise, no statistically significant differences (\(p>0.05\)) were observed (Table 3). Table 4 presents the comparison of the results obtained for Lip to E-plane and Nasolabial angle against the study groups. Statistically significant results were presented for Upper lip to E-plane (\(p=0.002\)), where the mean score for the cleft lip and palate group was \(-2.32\) points (SD = 1.5 points) and for the cleft lip group the mean score was \(-1.17\) points (SD = 1.3 points). Otherwise, no statistically significant differences (\(p>0.05\)) were observed (Table 4). Table 5 presents the correlations between SNA, SNB and ANB parameters in the cleft lip and palate group. A statistically significant positive correlation was observed between SNA and SNB scores. This indicates that subjects who have a greater degree of maxillary prognathism (SNA) also have a greater degree of mandibular prognathism (SNB). (Table 5).
