We describe here the case of a female newborn baby with a bilateral complete transverse facial cleft. Obstetrical ultrasound had revealed an increased amount of amniotic fluid from 28 weeks' gestation without fetal hydrops or congenital anomalies. A 1900-g baby girl born at 36 weeks' gestation presented with bilateral wide facial clefts with macrostomia, microphthalmia, nose, and auricular deformities. Her breathing was dependent on life support, which was discontinued 2 hours after birth. An autopsy revealed no congenital malformations in vital organs but the absence of the olfactory nerves. Polyhydramnios and respiratory arrest after birth were presumed to be due to central disintegration of swallowing and breathing, in this case with brain anomaly.

Objectives: We aimed to characterize a craniofacial skeletal phenotype (CSP) of adult obstructive sleep apnea (OSA) patients from a multidimensional perspective, exploring the impact of transverse skeletal discrepancy (TSD) on multivariable polysomnographic profiles.
Materials And Methods: This retrospective, cross-sectional study included 102 adult OSA patients. Sagittal, vertical, and transverse skeletal patterns were categorized on the cone beam computed tomography images.

: This study aimed to compare the effects of surgically assisted rapid palatal expansion (SARPE) techniques and their combinations on the stresses (von Mises, maximum principal, and minimum principal) and displacements that occur in the maxilla, facial bones, and maxillary teeth using three-dimensional finite element analysis (FEA). : SARPE was simulated using seven different osteotomy techniques. The FEA models were simulated with a combination of various osteotomies, including midpalatal and lateral osteotomies, lateral osteotomy with a step, and separation of the pterygomaxillary junction.

Objectives: This study analyzed the differences in the upper airway of patients with skeletal Class III high-angle malocclusion with and without mandibular deviation, and further investigated whether there are differences in the changes in upper airway space after orthognathic surgery between the two groups.
Materials And Methods: 15 patients with skeletal Class III high-angle malocclusion and mandibular deviation, and 15 patients without mandibular deviation were selected to explore the impact of mandibular deviation on the upper airway. Additionally, 16 patients with mandibular deviation undergoing orthodontic-orthognathic combined treatment, and 13 patients without mandibular deviation, were selected to investigate the differences in the changes in upper airway space after orthognathic surgery between the two groups.

Disruption of extracellular pH and proton-sensing can profoundly impact cellular and protein functions, leading to developmental defects. To visualize changes in extracellular pH in the developing embryo, we generated a zebrafish transgenic line that ubiquitously expresses the ratiometric pH-sensitive fluorescent protein pHluorin2, tethered to the extracellular face of the plasma membrane using a glycosylphosphatidylinositol (GPI) anchor. Monitoring of pHluorin2 with ratiometric fluorescence revealed dynamic and discrete domains of extracellular acidification over the first 72 h of embryonic development.

Introduction: The relationship between facial asymmetry and cervical anomaly is rarely mentioned in the diagnosis of dento-maxillo-facial orthopaedics. It is regrettable that the study of the cervical spine is often ignored in the etio-pathogenesis of these dysmorphoses, particularly in cases of facial asymmetry.
Objective: The aim is twofold: to encourage orthodontists and maxillofacial surgeons to make a systematic study of the cervical spine in craniofacial dysmorphoses and in particular craniofacial asymmetries, without claiming that they are becoming specialists in cervical spine pathology, and to introduce the necessary training in malformations of this anatomical region as part of the orthodontist specialisation curriculum.
