Objective: To evaluate the long-term effect of timing of 1-stage palatoplasty on midfacial growth in patients with cleft lip and palate (CLP).
Design: Retrospective observational cohort study.
Study Setting: Institutional hospital.
Patients: One hundred twelve patients with CLP who underwent palatoplasty and were divided into 3 groups: group I: operated between 9 and 11 months; group II: operated between 18 and 20 months; and group III: operated between 21 and 24 months.
Interventions: All patients underwent von Langenbeck palatoplasty technique, which was converted to a Bardach 2-flap technique in case of any technical difficulties. The patients were followed up between 8 and 9 years when they reported for secondary alveolar bone grafting. Postsurgical cephalometric and dental casts measurements were taken for midfacial growth analysis.
Main Outcome Measures: The cephalometric measures were analyzed for midfacial growth and compared within the groups.
Results: Statistically significant difference ( < .01) was found on comparing the cephalometric parameters such as sella-nasion-A point angle (SNA), A point-nasion-B point angle (ANB), n toperpendicular to point A (N-perpA), condylon to point A (Co-A), anterior nasal spine to posterior nasal spine (ANS-PNS), nasion to Anterior nasal spine (N-ANS), nasion to menton (N Me), and witts appraisal (Witt (AO-BO)) in group I when compared to both group II and group III patients, implying deficient midfacial growth in group I. No statistical difference was found in the cephalometric values between group II and group III. Group II had better cephalometric measurements than group III, showing better growth in group II than group III. Overall, there was less incidence of midfacial hypoplasia in patients treated between 18 and 20 months (group II).
Conclusion: We conclude that palatal closure carried out at 18 to 20 months and 21 to 24 months is associated with better midfacial growth when compared to closure at 9 to 11 months. The best time to operate would be between 18 and 20 months to avoid speech disturbances. Midfacial growth can be greatly influenced by the timing of 1-stage palatoplasty.

Aim: To assess tissue perfusion changes and wound healing biomarker levels after root coverage procedures with coronally advanced flap in combination with the cross-linked xenogeneic collagen matrix (CCMX), loaded either with a placebo or recombinant human platelet-derived growth factor-BB (rhPDGF).
Methods: This study was designed as a secondary analysis from a previously published clinical trial, and it assessed the tissue perfusion changes over 6 months around multiple gingival recession defects, treated with either with CCMX alone (control) or with CCMX + rhPDGF (test). High frequency Doppler ultrasonography (HFUS) scans were obtained at sites of interest at baseline, 2 weeks, 3 months, and 6 months after surgery.

Anterior-posterior (A-P) elongation of the palate is a critical aspect of integrated midfacial morphogenesis. Reciprocal epithelial-mesenchymal interactions drive secondary palate elongation that is coupled to the periodic formation of signaling centers within the rugae growth zone (RGZ). However, the relationship between RGZ-driven morphogenetic processes, the differentiative dynamics of underlying palatal bone mesenchymal precursors, and the segmental organization of the upper jaw has remained enigmatic.

Variable growth patterns and multifactorial mechanisms cause variation in facial shape. These differences in facial morphology pose challenges for craniofacial reconstruction. Three-dimensional (3D) imaging modalities are a valuable resource for examining these variations.

Objective: To quantitatively assess the impact of early versus late surgical intervention on midfacial growth using a mouse model.
Methods: A full-thickness mucoperiosteal flap surgery was performed on newborn (P17) mice and on neonatal (P30) mice. High-resolution micro-computed tomographic imaging coupled with histomorphometric analyses was used to assess craniomaxillofacial growth.
