Since results of surgical correction of unilateral cleft lip and palate (UCLP) are controversial, and there is no study in this regard among Iranians, this study was conducted to document lateral cephalometric measurements of such cases, with respect to age, gender, and cleft side.
In this cross-sectional study, 45 lateral cephalographs of individuals with UCLP who had undergone surgery but not orthodontic treatment were traced and 30 skeletal, dental and soft-tissue cephalometric measurements were measured. Parameters were compared between patients with UCLP and cephalometric norms. They were also compared between males and females, two age groups (≤8 and>8 years), and sides of cleft using the Student's t-test.
Only S-N-Pog and U1-SN values were significantly different between this sample and cephalometric norms. The variables were not significantly different between males and females. However, the values of ANB, Wits appraisal, Go-Gn, Go-Pog, U1-SN, interincisal angle, distance of upper lip to Ricketts E-line, and nasopharyngeal depth were significantly different between patients≤8 and>8 years (P<0.05). The S-N-Pog angle, Wits appraisal, Go-Gn, Go-Pog, U1-SN, interincisal angle and hypopharyngeal depth were significantly different between patients with right- and left-side clefts (P<0.05).
Measurements of patients with repaired UCLP were similar to cephalometric norms except for two parameters.
由于单侧唇腭裂（UCLP）手术矫正的结果存在争议，且伊朗尚无这方面的研究，因此本研究旨在记录此类病例的头颅侧位测量数据，涉及年龄、性别和腭裂侧别。
在这项横断面研究中，对45例接受过手术但未接受正畸治疗的UCLP患者的头颅侧位片进行了描图，并测量了30项骨骼、牙齿和软组织的头颅侧位测量指标。将UCLP患者的参数与头颅侧位测量标准进行比较。还使用学生t检验比较了男性和女性、两个年龄组（≤8岁和>8岁）以及腭裂侧别的参数。
该样本与头颅侧位测量标准之间仅S-N-Pog和U1-SN值存在显著差异。男性和女性之间的变量无显著差异。然而，≤8岁和>8岁患者之间的ANB、Wits评估、Go-Gn、Go-Pog、U1-SN、切牙间角、上唇至Ricketts E线的距离以及鼻咽深度值存在显著差异（P<0.05）。右侧和左侧腭裂患者之间的S-N-Pog角、Wits评估、Go-Gn、Go-Pog、U1-SN、切牙间角和下咽深度存在显著差异（P<0.05）。
除两个参数外，修复后的UCLP患者的测量结果与头颅侧位测量标准相似。
