Objectives: to evaluate the cephalometric and craniofacial measurements in unilateral and bilateral cleft lip and palate (CLP) patients and to investigate the effect of these measurements in growing and non-growing cleft patients using cone beam computed tomography (CBCT) 3D software, and to compare them to healthy individual.
Setting and Sample population: Retrospective study was performed in Department of pedodontics and Orthodontics, October 6 University. The study sample comprised unilateral and bilateral 36 growing CLP (aged 6-17years), and 24 non-growing CLP (aged 18- 40 years). The control group included 60 Non-CLP subjects. Methods: Cephalometric measurements were obtained using CBCT software, all measurements were assessed by Mann-test to clarify differences between study samples. Results: There was a significant difference between (Growing Bilateral) and (Control Growing) for (MP-SN, B, A, ANB, SNB & ANS-ME) and There was a significant difference between (Growing Unilateral) and (Control Growing) for (MP-SN, B, SNA, SNB, GO-GN, GO-GN, N-ANS & ANS-ME). While there was a significant difference between (Non-Growing Bilateral) and (Control Non-Growing) for (MP-SN, B, A, SNA, SNB, GO-GN, & ANS-ME) and there was a significant difference between (Non-Growing Unilateral) and (Control Non-Growing) for (MP-SN, B, A, SNA, SNB & ANS-ME) where (Z) values were significant at (0.05).
Conclusion: Our study shows that there was significant increase in mandibular length in both growing and non- growing BCLP than of UCL, in growing UCLP there was reduced upper face height and in growing BCLP there was increased lower face height
