Which flap moves tissue by pivoting around a fixed point to fill an adjacent defect?

A bilobed flap is most commonly used to reconstruct defects of which anatomic site?
Answer: Nasal tip and ala
The bilobed flap is classically used for distal nasal (tip/ala) reconstruction.
Full-thickness skin grafts differ from split-thickness grafts by including?
Answer: Epidermis and full dermis
Full-thickness grafts contain the entire epidermis and dermis but no subcutaneous fat.
What is the initial phase of skin graft survival before revascularization?
Answer: Imbibition
Plasmatic imbibition nourishes the graft by diffusion during the first 24-48 hours.
Which relaxed skin tension line orientation minimizes scar visibility?
Answer: Parallel to RSTLs
Incisions placed parallel to relaxed skin tension lines heal with less noticeable scars.
A dog-ear deformity at the end of an elliptical closure is best corrected by?
Answer: Excising the redundant standing cone of tissue
