We present a new method of fixation for creation of the vestibular sulcus in cases of open or closed submucous vestibuloplasty. Kirschner-wires (diameter 0.5 mm) are drilled through the mucous membrane into the bone. The wires keep the hand cut oval elastic sheets in place to adapt the mucous membrane to the periosteum at the deepest point of the vestibule respectively. Advantages of the method in comparison to other fixation techniques are discussed.
