BACKGROUND Fronto-orbital advancement for nonsyndromic craniosynostosis has been thought to injure frontal sinus buds, lead to chronic sinus disease, and influence final forehead shape. This study investigates the effect of fronto-orbital advancement in infancy on subsequent frontal sinus volume, morphology, and disease. METHODS The authors conducted a retrospective review of nonsyndromic cra...

A case of monozygotic male twins discordant for skeletal and cardiac defect is reported. One twin had the hemifacial microsomia type of the oculo-auriculo-vertebral dysplasia. The cotwin had no asymmetry of the face and normal ears, but preaxial polydactyly and ventricular and auricular septal defects. The cotwins were concordant for craniostenosis with a ridge metopic suture. Karyotypes were n...

Materials and methods This study included 300 human adult skulls, which were obtained from the Forensic Osteology Research Center, Faculty of Medicine, Chiang Mai University. The metopic suture and supraorbital ridge were observed macroscopically. The degree of supraorbital ridge was classifi ed into 4 levels. The 1st level had a massive prominence, the 2nd showed fair prominence, the 3rd indic...

PURPOSE: Non-syndromic sagittal and/or metopic craniosynostosis, occurring once in every 4,000 live births, accounts for half of all craniosynostosis cases. Despite success in identifying the genes underlying rare syndromic craniosynostoses, mutations in these genes are very rarely found in their non-syndromic counterparts. We considered that the often sporadic occurrence of non-syndromic crani...

Introduction Frontal bone is one of the unpaired bones of the skull. The bone develops in two halves and presents a metopic suture between the two in the fetal life; however, the suture disappears completely before or shortly after birth. Bregma is the meeting point of the sagittal and coronal sutures. It is represented by the anterior median fontanelle in the fetal life. The fontanelle obliter...
