Arhinia is a rare congenital malformation characterized by lack of the formation of external and internal nasal structures. Restricted midfacial growth is secondary to the loss of the midfacial growth centers. Staged reconstruction of the nasal passage and external nose is required. Vertical distraction osteogenesis is a beneficial step in the overall reconstructive program. This provides for additional bone and soft tissue for both improved aesthetic facial proportions and later surgical interventions.

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.

Children exposed prenatally to antiepileptic drugs may have a typical facies characterized by midfacial retrusion, a short nose, and anteverted nares. Our aim was to determine whether the shape of the maxilla was altered in its sagittal displacement, or whether the defect in the underlying articulation with the cranial base was responsible for the appearance of midface retrusion. Our hypothesis was that the sphenoid bone as well as the maxilla and other bones in the cranial base were affected by the anticonvulsant medication.

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.
