Purpose: To evaluate the effect of cleft width and the pre-surgical position of the permanent cuspid, on the success of secondary alveolar bone grafts, using preoperative and post-operative radiographs.
Methodology: A total of 20 cases treated with secondary alveolar bone grafting for alveolar clefts were included in the study. Pre-surgical maxillary occlusal radiograph was used to determine the cleft width. Canine position was assessed by marking 6 points on a pre-surgical intra oral periapical radiograph. Alveolar bone contour and the success of bone grafts were determined using 11 points marked on post-operative periapical radiographs taken after a minimum follow-up of 6 months.
Results: Linear regression analysis of pre-operative cleft width and pre-operative position of the permanent cuspid were carried out on the bone graft success which was determined using post-surgical periapical radiographs. P < 0.05 was set. The results obtained had weak correlations and were statistically not significant.
Conclusion: We concluded that the success of the alveolar bone graft has minimal or no relation to the pre-operative width of the cleft or the position of the permanent cuspid at the time of grafting.

Background: Patients with cleft lip and palate (CLP) often exhibit unique anatomical variations in the pterygoid plates, which can influence fracture patterns at the pterygomaxillary junction (PMJ) during Le Fort I osteotomy. These differences may increase the risk of unfavorable fractures, complicating surgery and recovery.
Purpose: The study purpose was to measure the association between the osteotomy level with the PMJ fracture patterns in CLP patients undergoing Le Fort I osteotomy.

Background: The purpose of this study was to analysis the nostril symmetry and nasal stability following secondary rhinoplasty performed with either nasal septal cartilage implantation (G1) or simple alar cartilage suspension and internal fixation (G2) in patients with unilateral secondary cleft nasal deformity.
Methods: Nostril and alar symmetry were analyzed retrospectively in 13 consecutive patients in G1 and 17 in G2. Assessment of three indexes was first performed using photogrammetric measurements of photographs at pre-operation(T1), 7 days after repair (T2), and at least 6 months after repair (T3).

Introduction: This study aimed to examine the relationship between the relative opening of the ICA (RO-ICA) and the structure of the ciliary cleft (CC) using Ultrasound Biomicroscopy (UBM).
Materials And Methods: Clinical data from 31 eyes of 17 dogs at the Veterinary Teaching Hospital of Chungbuk National University, Korea, were analyzed. RO-ICA was categorized as "Slightly Narrow", "Narrow", "Open", and "Wide Open", with eyes further grouped into "Narrow" (including Slightly Narrow and Narrow) and "Open" (including Open and Wide Open) for analysis.
