Anatomy
The submental island flap, harvested from the suprahyoid region, is an axial patterned flap based on the constant submental branch of the facial artery9. The submental artery arises from the facial artery deep to the submandibular gland. It runs medially on the mylohyoid muscle below the mandibular border, giving off 1–4 cutaneous perforators that pierce the overlying platysma muscle before forming a subdermal plexus that anastomoses extensively with the contralateral branches11. The submental
Methods
The patient is placed supine with the head moderately extended. A spindle-shaped skin paddle is planned horizontally and outlined on the area served by the submental artery, which originates 5.5 cm anterior to the angle of the mandible14. The upper limit of the flap is at least 1 cm behind the mandibular arch, to hide as much of the scar as possible and to prevent inferior lip eversion. The lower limit is determined after a pinch test of the submental skin between two fingers to determine that
Results
The submental island flap was used on 12 patients (8 men and 4 women) treated between August 2001 and May 2005. Every patient underwent primary reconstruction after excision of a malignancy. The mean patient age was 67 years. Two of the 12 cases underwent reconstruction after ablative surgery for squamous cell carcinoma, one in the right pre-auricular region and the other in the left upper alveolar ridge. Three patients had epidermal carcinoma: one involving the left oral tongue and left cheek
Case 1
A 58-year-old man was seen with a T2 squamous cell carcinoma of the posterior cheek mucosa that extended into the maxillo-malar sulcus and tuber maxillae (Fig. 1). Using Jaeger's incision, the patient underwent resection of the carcinoma involving the posterior cheek, anterior part of the tonsils and tuber maxillae, with selective neck dissection (Fig. 2). After tumour resection, a left-side pedicle submental island flap was elevated and transferred to the defect through a subcutaneous tunnel
Discussion
The submental flap is a valuable option for the reconstructive surgeon for orofacial defects following oncological resections. Owing to its reliability, this flap is a good alternative to other cervical skin flaps, such as the platysmal flap or supraclavicular flap, which have limited mobility, unpredictability and leave an unacceptable scar at the donor site. The use of a submental island flap may eliminate the need for a distant flap for head and neck reconstruction. Harvesting is easy to

2021, American Journal of Otolaryngology - Head and Neck Medicine and SurgeryCitation Excerpt :The submental artery island flap (SAIF), first described by Martin in 1990, was created to provide reliable coverage of defects in the lower third of the face while simultaneously hiding the donor site scar under the mandible [7]. It has been shown to successfully repair defects over regions containing a beard, mustache, oral commissure, auricle, oral cavity, or the nose [8–27]. Centered on the submental artery, a facial artery branch, the flap was initially developed to cover only the bottom third of the face.
