Mucoperiosteal Flap
A full-thickness surgical flap comprising both the mucosal and periosteal layers, elevated in continuity to expose the underlying alveolar bone.
Full Definition
A mucoperiosteal flap is the standard flap design in resective and regenerative periodontal surgery. By elevating the periosteum together with the overlying mucosa as a single unit, the surgeon achieves complete access to the alveolar bone without disrupting the periosteal blood supply to the bone. This is in contrast to a split-thickness (partial-thickness) flap, in which the periosteum is left on the bone surface. The choice between full-thickness and split-thickness flap design has direct implications for post-operative tissue volume and wound healing. Editors should note that 'mucoperiosteal flap' and 'full-thickness flap' are synonymous and may require standardisation within a text.
Usage
Usage note: 'Full-thickness flap' and 'mucoperiosteal flap' are synonymous; editors should standardize to one term within a document unless the author deliberately contrasts them for teaching purposes.
