Abstract
Free omental tissue transfer is a versatile reconstructive option for trunk, head and neck, and extremity reconstruction. Its utility is due to the length and caliber of the vascular pedicle and the malleability and surface area of the flap. We report our experience with omental free flap coverage of complex upper-extremity defects. A retrospective analysis of eight omental free-tissue transfers in seven patients with complex upper-extremity defects between 1999 and 2008 was performed. Indications, operative technique, and outcome were evaluated. Patient age ranged from 12 to 59 years with five male and two female patients. Indications included tissue defects due to crush-degloving injuries, pitbull mauling, or necrotizing soft tissue infection. All patients had prior operations including: revascularization, debridement, tendon repair, skin grafts, and/or fixation of associated fractures. One patient sustained severe bilateral crush-degloving injuries requiring free omental hemiflap coverage of both hands. The mean defect size was 291 cm2 with all patients achieving complete wound coverage. No flap loss or major complications were noted. Laparoscopic-assisted omental free flap harvest was performed in conjunction with the general surgery team in three cases. Mean follow-up was 2 years. The omental free flap is a valuable, often overlooked reconstructive option. The long vascular pedicle and large amount of pliable, well-vascularized tissue allow the flap to be aggressively contoured to meet the needs of complex three-dimensional defects. In addition, laparoscopic-assisted harvest may aid with flap dissection and may result in reduced donor-site morbidity.
