Abstract
(1) Background: This article focuses on examining components affecting the overbite, overjet, and the effect of palate surgery on craniofacial morphology with a concomitant cleft lip fusion scar, and a comparison of patients who had only a cleft lip fusion scar. Patients with unilateral cleft lip (UCL) and patients with unilateral cleft lip and palate (UCLP) were included in the study. We aimed to find if cephalometric parameters were significantly different in these groups. (2) Material and methods: The study group consisted of a lateral cranial radiograph of patients with UCLP (n = 30) and UCL (n = 30). Cephalometric radiographs were saved electronically, and cephalometric analysis was performed using a computer program. (3) Results: We observed that a statistically significant higher degree of maxillary prognathism occurred in the UCL than in the UCLP. We observed the anterior position of the upper lip in relation to E-line in patients with cleft lip. (4) Conclusions: The results present the effect of cleft palate surgery on further forward growth of the maxilla. There was a decreased ANB angle present in the skeletal class II in patients with UCL and UCLP. The SNB angle was not increased, and the reverse overjet was due to the rectroclination of the upper incisors and protruded lower incisors.
Highlights
Orofacial clefts are the most common head and neck congenital malformation [1] and are the second most common congenital abnormality in children, after heart defects [2,3].Unilateral cleft lip and palate (UCLP) accounts for 45% of all clefts; the second most frequent is unilateral cleft lip (UCL), which involves 25% of patients [4]

Summary
Unilateral cleft lip and palate (UCLP) accounts for 45% of all clefts; the second most frequent is unilateral cleft lip (UCL), which involves 25% of patients [4]. Both groups of patients require complex multidisciplinary care [5]. Lack of soft and hard tissue continuity contributes to craniofacial deformities. These include skeletal abnormalities, such as abnormal development of the maxillary bones, frontal, zygomatic, and orbital bones, as reported in a study conducted in Taiwan [6]. It is noteworthy that there was no statistical difference in the ossification time of the SphenoOccipital Synchondrosis in patients with UCLP compared to patients without cleft [7]
