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.

Boiling Point Elevation The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

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
The vascular pedicle maintains the flap’s connection to its blood supply while the tissue is mobilized. Protecting this attachment allows the mucosal flap to remain viable as it is rotated or repositioned over a reconstructive target. This principle is especially important when the flap must cover exposed tissues or contribute to closure after endoscopic skull base surgery.
These dissection planes separate the mucosal flap from the underlying septal cartilage and bone while supporting controlled tissue release. Working in the appropriate plane helps surgeons elevate the flap along its intended surface and preserve the vascular pedicle. The selected plane therefore influences whether the flap can be mobilized for subsequent rotation or repositioning.
Incision placement determines how the mucosal tissue can be released and mobilized from the nasal septum. Carefully positioned cuts support access to the subperichondrial or subperiosteal plane while maintaining the attachment needed for vascularized reconstruction. This relationship between incision design and pedicle preservation is central to preparing tissue that can cover a surgical defect.
After endoscopic skull base surgery, the repositioned flap can cover defects and exposed tissues, helping restore an anatomical barrier. Its use is particularly relevant to watertight closure of cerebrospinal fluid leaks. Effective coverage may also reduce postoperative complications by placing living mucosal tissue across the reconstructive site rather than leaving the defect uncovered.
The procedure begins with carefully planned incisions in the nasal septal mucosa. Surgeons then dissect in the subperichondrial or subperiosteal plane, separating the flap from cartilage and bone while preserving its vascular pedicle. Once adequately released, the tissue can be rotated or repositioned to cover the intended defect and support reconstruction.
This technique is used when reconstructive coverage is needed after procedures that create defects or expose tissues, particularly in endoscopic skull base surgery. Its clinical relevance extends across otolaryngology, neurosurgery, and minimally invasive cranial reconstruction. The resulting coverage can help re-establish anatomical barriers and support management of cerebrospinal fluid leaks.
