[Advances on anatomic study and clinical application of submental artery island flap]
Abstract:
After more than 20 years of development, submental artery island flap (SMAIF) has become a versatile flap for head and neck reconstruction of the defects after tumor resection,trauma or facial deformity.The design of SMAIF is flexible and diverse. According to repair requirements,various types of flap can be harvested based on the different composition. SMAIF mainly used as an orthograde pedicled flap.It also can be used as a retrograde, free or hybrid variant.More modifications such as bipaddled, bipedicled, pre-expanded,deepithelialized were evolved. SMAIF shows some advantages including reliable blood supply, convenient preparation, well matched color with the facial skin, and the similar or even better repair effect compared with free flaps.In addition,the submental artery perforator flap and the submental vascularized lymph node flap are the latest clinical application achievements derived from the progress of anatomic research.They further improve the level of preparation skill and expand the indications of SMAIF.
