OBJECTIVE To compare the platysma flap with submental flap in terms of tumor and flap characteristics, operative properties and the functional outcomes. METHODS A total of 65 patients presented with tumors of head and neck and underwent curative tumor resection with different neck dissections at the Department of Oromaxillofacial-Head and Neck Surgery, School of Stomatology of China Medical U...

SUMMARY Submental flap surgery is a useful and versatile reconstructive procedure. Currently, disagreement exists regarding the need to include the anterior belly of the digastric muscle or mylohyoid in the submental flap. The report outlines the value of excluding normal and variant anterior digastric and mylohyoid musculature from the submental flap as a contingency plan for marginal mandibul...

OBJECTIVE Vascularized groin lymph node flaps have been successfully transferred to the wrist to treat postmastecomy upper limb lymphedema. This study investigated the anatomy, mechanism and outcome of a novel vascularized submental lymph node (VSLN) flap transfer for the treatment of lower limb lymphedema. METHODS Bilateral regional submental flaps were dissected from three fresh adult cadav...

The pharyngeal airway is surrounded by soft tissues that are also enclosed by bony structures such as the mandible, maxilla, and cervical spine. The passive pharyngeal airway is therefore structurally analogous to a collapsible tube within a rigid box. Cross-sectional area of the tube is determined by transmural pressure, the pressure difference between intraluminal and extraluminal pressures. ...

It has been suggested that the primary motor cortex plays a substantial role in the neural circuitry that controls swallowing. Although its role in the voluntary oral phase of swallowing is undisputed, its precise role in motor control of the more reflexive, pharyngeal phase of swallowing is unclear. The contribution of the primary motor cortex to the pharyngeal phase of swallowing was examined...

The anatomic understanding of the superficial compartments of the head and neck are evolving. Recently, studies have shown that the superficial fat is sequestered into separate "compartments"; however, the superficial anatomy of the submental region of the neck has yet to be defined, and improved understanding of this area may lead to advances in our ability to rejuvenate the neck. This cadaver...

BACKGROUND The submental artery island flap is a reliable reconstructive option for lower face defects. Advantages of this flap include suppleness of tissue, excellent color and texture match to facial skin, a wide arc of rotation, prominent blood supply, and a well-hidden donor site scar. METHODS This article describes a 61-year-old man with eccrine carcinoma of the chin necessitating extens...

Liposuction is commonly used to address submental fullness. This method, however, is dependent on the quality of the patient’s skin. Injury to the marginal mandibular nerve as well as over suctioning of the fat can lead to contour irregularities. Additionally, isolated submental liposuction may not address submental fullness and the aging face fully; thus, a cervicoplasty consisting of an open ...
