Combined Use of Nonvascularized Iliac Crest Bone Graft and Submental Island Flap in Mandibular Reconstruction: A Technical Note.

Reconstruction following segmental resection of the mandible due to tumors poses significant aesthetic and functional challenges. While vascularized free tissue flaps remain the gold standard, they are associated with prolonged operative time, high cost, requirement for microsurgical expertise, and donor site morbidity. We present a novel technique combining a nonvascularized iliac crest bone graft (NVICBG) with a submental island flap (SIF) for mandibular reconstruction. Between February 2024 and May 2025, three patients underwent this procedure. Graft and flap survival was achieved in all cases, with satisfactory functional and aesthetic outcomes based on clinical evaluation. Despite the limited sample size, this technique demonstrates promise as a practical and effective alternative, offering a short learning curve, high feasibility, and low complication rates. To our knowledge, this is the first report describing the combined use of NVICBG and SIF for mandibular reconstruction.
