To date, thick tissue defects are typically reconstructed by applying autologous tissue flaps or engineered tissues. In this protocol, we present a new method for engineering vascularized tissue flap bearing an autologous pedicle, to serve as a substitute to autologous flaps.

Source: David Guo, College of Engineering, Technology, and Aeronautics (CETA), Southern New Hampshire University (SNHU), Manchester, New Hampshire A wing is the major lift-generating apparatus in an airplane. Wing performance can be further enhanced by deploying high-lift devices, such as flaps (at the trailing edge) and slats (at the leading edge) during takeoff or landing. In this experiment, a wind tunnel is utilized to generate certain airspeeds, and a Clark Y-14 wing with a flap and slat...

Coronoid-Temporalis Pedicled Flap for Orbital Floor Defect Reconstruction
0 Views •
2025
This protocol presents a novel coronoid-temporalis pedicled flap (CTPF) technique for reconstructing small-to-medium orbital floor defects. CTPF avoids microvascular risks while maintaining biomechanical stability. Clinical cases demonstrate effective structural restoration, reduced complications, and preserved facial symmetry, offering a viable alternative to traditional grafts or alloplastic materials.
FAQs
Preserving the flap’s blood supply is central because the moved tissue must remain living while it covers the defect and becomes secured in its new position. Careful elevation helps maintain that connection, supporting healing and continued tissue function. If positioning disrupts the intended vascular support, the flap may not provide reliable coverage or protect underlying structures as planned.
Advancement, rotation, and return provide different ways to align living tissue with the area requiring coverage. The surgeon moves the flap as needed rather than treating every defect with the same geometry. This flexibility can help restore anatomy, cover an irregular defect, or protect an exposed structure while keeping the tissue positioned for secure fixation and healing.
Fixation stabilizes the flap after it has been positioned. Sutures or other fixation methods maintain tissue contact with the treated area during healing, limiting unintended movement of the reconstructed tissue. That stable relationship supports wound closure and helps the flap remain aligned with the anatomy it is intended to restore or protect.
Accurate positioning has consequences beyond simply covering a defect. It can support healing, preserve tissue, restore anatomy or function, and improve the treated area’s final appearance. These outcomes explain why the flap must be aligned carefully before fixation: placement determines how effectively the tissue serves its protective, reconstructive, or closure-related purpose.
A basic sequence begins with careful flap elevation while preserving its blood supply. The surgeon then advances, rotates, or returns the tissue according to the coverage required. After placement, fixation with sutures or another method maintains contact during healing. The sequence links tissue viability, positioning, and stable closure.
Flap repositioning may be considered when a defect needs coverage, when underlying structures are exposed, or when wound closure and tissue reconstruction are required. Its medical value is not limited to closing a wound: the approach can also help restore anatomy, preserve tissue, support function, and improve the treated area’s final appearance.
