| Abstract | ||||
| Objective: The purpose of this study was to investigate maxillofacial morphology using CBCT with the ultimate goal of finding whether differences existed in a two suggested subtypes of non-syndromic bilateral cleft lip and palate (BCLP) patients. Design: This retrospective study included CBCT data of 22 BCLP patients with mean age of 9.6 years. The patients were divided initially according to premaxillary characteristics into two groups and this classification was further confirmed by measurement of sella–nasion– point A angle (SNA), Group (P): This represent BCLP characterized by well-developed (P) prominent pre-maxilla and SNA >80±2, Group(R): This represent BCLP characterized by ill-developed (R) rudimentary pre-maxilla and SNA < 80±2. The relation between maxilla and mandible measured by point A–nasion–B point angle (ANB), angle of septal deviation (ASD) and anterior upper facial height (AUFH) were assessed using On-demand 3D software and was compared among the two groups. Results: Patients within group P showed significantly higher ANB (P value ≤ 0.001). Patients within group R showed significantly higher ASD angle (P value ≤ 0.05), while AUFH showed insignificant difference between the two groups (P value ≥ 0.05). Conclusions: Maxillofacial morphology measurements assessed in this study support that difference exist between the two investigated subtypes of non-syndromic BCLP. | ||||
