Expert consensus on application of submental island flap in oromaxillofacial head and neck defect reconstruction

Submental island flap (SMIF) is an axial flap that receives its blood supply from the submental artery, a branch of the facial artery. It is in close proximity with many oral and maxillofacial regions, and provides a good texture and color match. The flap is easy to prepare and suitable for repairing medium-sized defects of the oral and maxillofacial region with high survival rates. However, there are still controversies about the application of submental island flap both at home and abroad, mainly focusing on the oncological safety of submental island flap for patients with cervical lymph node metastasis and the preparation method of the flap. In order to unify and standardize the application of submental island flap in repair of oral and maxillofacial head and neck defects, this paper focuses on the collective wisdom of experts in oral and maxillofacial surgery of many medical colleges in China, and reaches an expert consensus, so as to guide the clinical application of submental island flap.
