The use of intraoperative scalp expansion by Foley catheter in one-stage closure for scalp defect-review of eight cases-

Abstract

Treatments for scalp reconstruction include simple closure by suturing, skin grafting, local flap, and free tissue transfer. In most cases, the optimal method is selected based on the defect size. Although simple suturing and local flaps are superior to other options for preserving hair-bearing qualities, careful selection should be made because advancements are limited. Intraoperative scalp expansion using a balloon-type expander was introduced in the 1980s, by which scalp defects less than 4 to 4.5 cm in length could be closed in one stage without an extra incision or skin graft. However, the mechanism of skin stretching by intraoperative expansion is unclear, and stretchback, scalp necrosis, and alopecia have been reported as postoperative complications. Intraoperative expansion was performed using Foley catheter balloons in eight cases of scalp defects. Patient characteristics, surgical techniques, postoperative courses, and complications were reviewed, along with relevant literature, which showed its usefulness even in a larger defect than that reported in combination with a local flap.
