Temporal Fascia Free Flap for Thumb Coverage in Electrical Burn Injuries: A Case Series Analysis With DASH Score Outcomes Evaluation

Abstract

Abstract Electrical burns pose unique challenges in reconstructive surgery due to the extensive tissue damage they cause. The thumb is particularly susceptible to electrical burns, leading to severe functional impairment. This case series introduces the use of the temporal fascia free flap for thumb coverage in patients with electrical burn injuries. The study aims to assess the functional outcomes of this approach using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. Six male patients underwent thumb reconstruction using temporal fascia free flaps following electrical burn injuries. The extent of the injury was assessed, and necrotic tissue was debrided. Functional outcomes were evaluated using the DASH questionnaire 6 months postoperation. All procedures were conducted in accordance with ethical guidelines, and informed consent was obtained from all patients. All patients achieved successful transplants using temporal fascia free flaps. The average DASH score at the 6-month follow-up indicated satisfactory functional recovery. Patients reported improvements in thumb mobility and functionality, and the cosmetic appearance of the thumb was acceptable. The appearance of the scar in the donor area was well-received. The temporal fascia free flap proved to be an effective method for thumb reconstruction following electrical burn injuries. Its thin and flexible nature allows for optimal contouring and improved range of motion. Although one case of partial flap loss was observed, overall functional and aesthetic outcomes were satisfactory. Further research with larger sample sizes is warranted to optimize surgical techniques and postoperative care for better outcomes.
