Abstract
Postoperative fixation is required for skin grafts on mobile sites. External wire-frame fixation technique has demonstrated a beneficial role for grafts in specific areas such as lips, eyelids, and fingers. Although this technique is sufficient in most cases, patients with psychosis fail to maintain the lip in resting position, which led us to consider using a more rigid fixation method, known as "Geometric wire-frame fixation." Surgical technique included fixing a perimeter frame around skin graft similar to the conventional external wire-frame fixation. In addition, a geometric frame was prepared to divide the area of the graft geometrically. Then, it was placed on gauze to compress the grafted skin, and connected to the perimeter frame. In case 1, a 33-year-old man with a history of schizophrenia and presenting with flame burn injury sustained while attempting suicide was admitted. The scar on the lips was excised, and an external wire-frame fixation was performed. However, postoperative vigorous mouth movements caused incomplete survival of the skin graft. Geometric wire-frame fixation was performed in the next operation, and the graft fully survived. The patient in case 2 was a 62-year-old man who developed a facial scar contracture after chemical injury by sulfuric acid. We performed geometric wire-frame fixation with contracture release of the upper lip, and the skin graft was fully taken. The geometric wire-frame fixation method allows for rigid fixation of the skin graft and can be considered as a valuable option, especially for lip reconstruction in poorly compliant patients who are unable to maintain proper resting lips.
