An Innovative Methodology: The Submental Island Flap Offers Enhanced Soft Tissue Coverage to the Vascularized Iliac Crest Flap.

The vascularized iliac crest flap has garnered widespread acclaim within the field of mandibular reconstruction attributable to its sufficient bone mass and congruent curved morphology. However, when the precise orientation of the iliac crest is imperative during mandibular reconstruction and there exists an accompanying defect within the oral soft tissue, the indispensability of an additional flap to facilitate concurrent defect repair becomes evident. In such instances, the submental island flap emerges as an exemplary candidate.
