Why "Deep"
A superficial neck lift tightens skin and the platysma muscle. A deep neck lift additionally addresses structures beneath the platysma: subplatysmal fat, the anterior belly of the digastric muscle, and — in selected cases — the superficial lobe of the submandibular gland. These deeper structures are often the true cause of a "full" or undefined neck that does not improve with skin tightening alone.
Anatomic Components
- Platysmaplasty: midline plication of the platysma muscle to eliminate banding
- Subplatysmal fat reduction: conservative excision of deep fat
- Digastric muscle contouring: selective reduction when hypertrophied
- Submandibular gland reduction: considered only in selected patients with visible gland ptosis
When It Is Combined With a Deep Plane Facelift
Many patients presenting for facial rejuvenation also want a defined jawline and cervicomental angle. A deep plane facelift addresses descent of the jowls and lateral neck; the deep neck lift addresses the submental (under-chin) region. Combining both in a single operation is common when indicated.
Risks
Beyond standard surgical risks, deep neck work introduces additional considerations: marginal mandibular nerve injury, salivary complications (when gland reduction is performed), and contour irregularities. Surgeon experience is important.
