The 27 Facial Sutures: Timing and Clinical Consequences of Closure.

Facial sutures contribute significantly to postnatal facial development, but their potential role in craniofacial disease is understudied. Since interest in their development and physiology peaked in the mid-twentieth century, facial sutures have not garnered nearly the same clinical research interest as calvarial sutures or cranial base endochondral articulations. In addition to reinforcing the complex structure of the facial skeleton, facial sutures absorb mechanical stress and generally remain patent into and beyond adolescence, as they mediate growth and refine the shape of facial bones.

Facial Suture Pathology in Syndromic Craniosynostosis: Human and Animal Studies.

Background: Facial deformities in syndromic craniosynostosis are not only functionally, psychosocially, and aesthetically impairing but also notoriously challenging to reconstruct. Whether facial suture synostosis plays a significant role in the pathogenesis of these deformities is inadequately studied in human patients.

Methods: The MEDLINE database was queried using a methodologically generated search term inventory.

Oral Flora and Perioperative Antimicrobial Interventions in Cleft Palate Surgery: A Review of the Literature.

Background: The role of perioperative antibiotics in cleft palate remains a topic of debate. Advocates stress their importance in preventing local and systemic infections and decreasing the incidence of oronasal fistula formation. However, few studies to date have directly evaluated the role of antibiotics and other antimicrobial measures in cleft palate surgery.

Long-Term Orthognathic Considerations in the Pierre Robin Sequence Patient.

Background: One of the arguments against early intervention for micrognathia in Pierre Robin sequence is the concept that the growth of the mandible will eventually "catch up." Long-term growth of the mandible and occlusal relationships of conservatively managed Pierre Robin sequence patients remain unknown. In this study, the authors evaluated the orthognathic surgery requirements for Pierre Robin sequence patients at skeletal maturity.

Effect of Cross-Sex Hormone Therapy on Venous Thromboembolism Risk in Male-to-Female Gender-Affirming Surgery.

Individuals with gender dysphoria often seek medical interventions, such as hormone treatment and surgery, to live as their identified gender. Cross-sex hormone therapy typically consists of various estrogen formulations which confer varying risks of venous thromboembolism (VTE). Currently, there is no standard practice by surgeons regarding the preoperative gender-affirming surgery (GAS) hormone regimen of male-to-female (MTF) patients to minimize thromboembolic postoperative complications.

Aberrant calcium channel splicing drives defects in cortical differentiation in Timothy syndrome.

The syndromic autism spectrum disorder (ASD) Timothy syndrome (TS) is caused by a point mutation in the alternatively spliced exon 8A of the calcium channel Ca1.2. Using mouse brain and human induced pluripotent stem cells (iPSCs), we provide evidence that the TS mutation prevents a normal developmental switch in Ca1.

Virtual Surgical Planning for Mandibular Reconstruction With the Fibula Free Flap: A Systematic Review and Meta-analysis.

Background: The fibula free flap (FFF) remains the criterion standard for complex mandibular reconstruction. Surgeons have incorporated virtual surgical planning (VSP) into the reconstructive algorithm with the assertion that VSP increases operative efficiency and may improve clinical outcomes. To date, no large-scale studies have analyzed these claims.

CDKN2B upregulation prevents teratoma formation in multipotent fibromodulin-reprogrammed cells.

Tumorigenicity is a well-documented risk to overcome for pluripotent or multipotent cell applications in regenerative medicine. To address the emerging demand for safe cell sources in tissue regeneration, we established a novel, protein-based reprogramming method that does not require genome integration or oncogene activation to yield multipotent fibromodulin (FMOD)-reprogrammed (FReP) cells from dermal fibroblasts. When compared with induced pluripotent stem cells (iPSCs), FReP cells exhibited a superior capability for bone and skeletal muscle regeneration with markedly less tumorigenic risk.
