Head and neck surgeries often accompany with moderate-sized defects that require time-consuming reconstructions by free flaps. The submental flap is a versatile and time-effective option for reconstruction of orofacial defects providing acceptable cosmetic and functional results without requiring microsurgical techniques. A retrospective case series study of patients who underwent reconstruction with the submental flap between 2009 and 2013 was conducted. There were 36 patients (33 men and 3 women), with a mean age of 56.4 years, enrolled in this study. The primary lesion sites included oral cavity (24 patients), pharynx (8 patients), larynx (2 patients), neck (1 patient) as well as maxillary sinus (1 patient). All flaps were harvested as the myocutaneous flaps. All donor sites were closed primarily without the need of additional surgery. No complete loss of the flap was encountered and two cases developed marginal necrosis of the flap. The submental flap had a reliable pedicle and had minimal donor-site morbidity. It is an excellent flap option for patients with small- to medium-sized defects in head and neck region.

The vascular anatomy of submental flaps (SFs) represents a determining factor in successful SF raising. However, little attention has been focused on the venous return of SFs. Thus, the present study aimed to investigate SF venous return. This study enrolled patients who underwent SF reconstructive surgery in a tertiary referral center between November 2009 and October 2016. The drainage pathway of the SF venous return was routinely identified during the course of our operations to prevent damage during head and neck surgery. The venous return data of 70 patients were reviewed. The size of the flaps ranged from 15 to 84 cm(2), and total flap loss was not observed in the case series. All of the submental arteries originated from the facial artery; however, the submental veins of 70 patients returned to either the internal jugular vein (IJV, 72.9%) or the external jugular vein (EJV, 27.1%). Our data suggest that drainage of the submental vein into the EJV, which has been previously overlooked, should receive greater attention during SF surgeries. The results support mandatory preservation of the EJV and IJV and indicate that vascular anatomy is a determining factor for successful SF raising.
