Traditional surgical approaches often address only subcutaneous fat and, occasionally, the platysma muscle, while neglecting subplatysmal structures. This limited focus may produce suboptimal outcomes or even worsen existing issues, resulting in contour irregularities that are difficult to correct. In many cases, additional factors deep to the platysma—such as subplatysmal fat, the anterior bellies of the digastric muscles, perihyoid fascia, and the submandibular glands—contribute to obtuse neck contours. For these patients, a submental incision provides access for precise management of these deep structures. Achieving natural and durable neck contours requires detailed anatomical knowledge, targeted modification of subplatysmal elements, platysma tightening, and judicious preservation or removal of subcutaneous fat. Despite concerns about potential risks, deep neck contouring consistently yields long-term, natural results with low complication rates.
