Subgaleal vs Subperiosteal Flap Adherence in the Rabbit Model

Methods: Twelve New Zealand white rabbits (weight, 3.1-3.5 kg) were evenly divided into 2 groups and underwent forehead flap elevation via subperiosteal or subgaleal dissection, depending on the group assignment. Two rabbits were not operated on and served as controls. Histologic and biomechanical testing (tensiometer) was performed at 2, 4, 6, 8, and 10 weeks to assess adherence and wound strength.
