Classical orthognathic procedures have long been known to improve the facial esthetic contours and proportions of face by restoring the skeletal foundation, on which the soft-tissue drapes. Distraction osteogenesis was introduced to solve complex skeletal abnormalities in patients with craniofacial conditions that could not be solved by classical orthognathic surgery techniques. The gradual expansion in this group of patients showed not only greater skeletal stability, but the expansion at various tissue planes improved the facial appearance.

Preoperative surgical planning incorporating computer-aided design and manufacturing is increasingly being utilized today within the fields of craniomaxillofacial, orthopedic, and neurosurgery. Application of these techniques for craniosynostosis reconstruction can include patient-specific anatomic reference models, "normal" reference models or patient-specific cutting/marking guides based on the presurgical plan. The major challenge remains the lack of tangible means to transfer the preoperative plan to the operating table.

Article Synopsis
  • - The study explores a new technique called in situ distraction osteogenesis to widen the fibula before it's used for mandibular reconstruction, addressing the issue of fibula bone width being inadequate for matching mandibular height.
  • - Researchers conducted a retrospective review of three patients aged 9 to 13 with serious mandibular hypoplasia, successfully achieving bony union and minimal complications post-surgery over a five-year follow-up period.
  • - The findings suggest that this innovative approach allows for effective reconstruction of complex mandibular defects while maintaining critical bone structure and supporting further orthognathic surgery if needed.

Background: Immune complexes (ICs) bind to and activate platelets via FcγRIIA, causing patients to experience thrombocytopenia, as well as an increased risk of forming occlusive thrombi. Although platelets have been shown to mediate IC-induced pathologies, the mechanisms involved have yet to be fully elucidated. We identified that apoptosis signal-regulating kinase 1 (ASK1) is present in both human and mouse platelets and potentiates many platelet functions.

Apoptosis signal-regulating kinase 1 (ASK1) is a mitogen-activated protein kinase kinase kinase (MAPKKK) that regulates activation of the c-Jun N-terminal kinase (JNK)- and p38-stress response pathways leading to apoptosis in nucleated cells. We have previously shown that ASK1 is expressed in platelets and regulates agonist-induced platelet activation and thrombosis. However, the mechanism by which platelet agonists cause activation of ASK1 is unknown.
