Preparation of vascularized forearm dermal fat flap and repairing of donor site
Objective:This study prepared vascularized dermal fat flaps and introduced a local split-thickness skin graft from an in situ cutaneous area cutaneous area to manage forearm flap donor sites and evaluated the es-thetic and functional outcomes post-operatively.From July 2020 to June 2023,13 patients with soft tissue defects in Oral and Maxillary Area were repaired with tvascular forearm dermal fat flap.There were 8 males and 5 fe-males,aged from 42-71 years.The flaps ranged from 8 cm×7 cm to 7 cm×5 cm in size.The donor site defects were covered by local split-thickness skin graft from the in situ skins.The color matching degree,surgical scars,ranges of wrist movement and hand sensations in donor forearms were assessed at 6 months after surgery.Re-sults:The tvascular forearm dermal fat flaps for 15 cases all survived.All the local split-thickness skin grafts transplanted with this technique showed primary healing.The follow-up period for 6 months,Donor site exhibited suitabler color matching and there was not severe complications.Conclusion:The vascularized dermal fat flap pro-vides an alternative to conventional forearm flap harvest,which enables primary donor site closure with reduced rates of delayed donor site healing.The vascularized dermal fat flap is a relatively reliable repair method for soft defects in Oral and Maxillary Area.
