Craniofacial developmental concepts in dynamic osteotomies and the Nautilus technique: A procedure created in Brazil for the treatment of craniosynostosis.

Craniofacial development is the major focus of attention in surgical treatments for craniosynostosis. Growth rate, size, shape, and proportion of soft tissue and bone structures of the skull and face are determinant factors in the establishment of the vital functions of swallowing and breathing, as well as in the aesthetic balance of facial features, so important for the patient's psychological identity. This manuscript revisits the concept of craniosynostosis and reviews the major biological and anatomical factors that come into play in the developmental process of craniofacial structures, especially during infancy and early childhood.

Retrospective study on midfacial advancement in syndromic craniosynostosis: case series.

Aims: The aim of this study was to evaluate elastic distraction surgical procedures performed on patients with syndromic craniosynostosis using cephalometric analyses.

Methods: Eleven patients who underwent surgical midfacial advancement were divided into three groups: G1 - monobloc frontofacial; G2 - Le Fort III; and G3 - high-level Le Fort I. The cephalometric analyses were manually created through cephalometric radiographs of each patient: T1 - preoperative; T2 - 6 months postoperatively; and T3 - 12 months postoperatively.

Skull base cephalometric changes in cranial expansion by springs.

Background: The use of springs in cranial expansion has demonstrated to be effective for craniosynostosis treatment. The spring-exerted expansile action has been observed when springs are placed both in the sagittal and parasagittal regions, mainly in scaphocephaly. In this study, a variation in cephalometric measurements under expansible spring action on the skull base was analyzed.

Spring-mediated skull expansion: overall effects in sutural and parasutural areas. An experimental study in rabbits.

Purpose: The use of springs in cranial expansion has proven to be effective in the treatment of craniosynostosis. Spring-mediated expansion has been studied both in the sagittal and in parasagittal regions, especially in scaphocephaly. A rabbit model was used in the present study to analyze the effects of springs on the cranial vault and sutures.
