Assessment of Zygomaticomaxillary Suture Maturation in Patients With Unilateral Cleft Lip and Palate: Implications for Orthodontic Treatment Planning.

Introduction The zygomaticomaxillary suture (ZMS) is vital for craniofacial development and orthodontic treatment planning. Located at the junction of the zygomatic and maxillary bones, the ZMS undergoes significant changes during growth, affecting midfacial morphology and stability. Understanding ZMS maturation is essential for optimizing orthodontic interventions, especially in patients with cleft lip and palate (CLP), who often exhibit altered craniofacial growth patterns due to congenital deformities and surgical interventions. Methodology A retrospective analysis was conducted with 50 participants, including 25 patients with unilateral CLP and 25 age-matched controls. Clinical and radiographic data, including lateral cephalometric radiographs and cone-beam computed tomography (CBCT) scans, were collected to assess ZMS maturation stages. The stages, ranging from immature (stage 0) to fully mature (stage 4), were evaluated using established radiographic criteria. Statistical analyses, including Chi-square tests and logistic regression, were performed to compare the distribution of maturation stages between groups. Results Significant differences were observed in ZMS maturation stages between the cleft side, non-cleft side, and control group. The cleft side exhibited a higher prevalence of immature (stage 0) and early maturation (stage 1) stages compared to the control group, with mean values of 4 ± 1.2 and 5 ± 1.3, respectively. The control group showed a higher prevalence of fully mature (stage 4) sutures, with a mean value of 8 ± 1.4. The p-values for stages 0, 1, and 4 were 0.045, 0.034, and 0.039, respectively, indicating statistical significance. The findings highlight distinct maturation patterns in CLP patients, with delayed ZMS maturation on the cleft side. This suggests the need for tailored orthodontic interventions to accommodate prolonged growth phases in CLP patients. The study underscores the importance of detailed ZMS assessments for personalized treatment planning. Future research should focus on longitudinal studies to further understand CLP's impact on craniofacial development. Conclusion Assessing ZMS maturation provides critical insights for optimizing orthodontic and surgical treatment outcomes in CLP patients. By identifying specific developmental delays and tailoring interventions accordingly, clinicians can improve the effectiveness and stability of treatments. This study contributes to the growing body of evidence supporting individualized treatment plans based on precise developmental assessments.
