Reading the Neck: Fat, Muscle, Gland or Bone?

Two necks can look identical in a photograph and need completely different operations. One carries its fullness in subcutaneous fat that a cannula could address; the other hides it beneath the platysma, in deep fat, a bulky digastric or a ptotic gland. Treat the second like the first and the result is a neck that is tighter, not better.

That is why Day 01 of All About The Neck opens with analysis, before any technique is discussed.

The four owners of a full neck

• Fat: superficial (subcutaneous, above the platysma) or deep (subplatysmal, between the medial borders of the platysma and over the anterior digastric bellies).
• Muscle: platysmal bands and laxity, and the anterior digastric bellies, whose prominence or laxity can define the submental contour.
• Gland: a large or ptotic submandibular gland, visible below the mandibular border. See Submandibular gland management in deep plane neck lift.
• Bone: hyoid position and the projection of the chin and mandible, which set the skeletal frame the soft tissues drape over.

Skin quality sits across all four: it decides whether the envelope will redrape over a new foundation or simply hang from it.

Static examination

With the patient seated, head in neutral position and the Frankfort plane horizontal, look at:

• the cervicomental angle in profile and how sharply the jawline is defined;
• localized fullness: central submental, along the mandibular border, or in the submandibular triangles;
• chin projection and the apparent level of the hyoid;
• skin: thickness, elasticity, redundancy and sun damage.

Standardised photographs (frontal, both obliques, both profiles and flexion) make these observations repeatable and comparable after surgery.

Dynamic examination

Ask the patient to contract the platysma by grimacing or tensing the neck. Bands become visible, and the behaviour of the fullness tells you where it lives. Fat that can be pinched between the fingers above the contracted muscle is superficial. Fullness that persists or becomes more apparent beneath the contracted muscle suggests a deep contribution: subplatysmal fat, digastric bulk or gland.

Skeletal support and its limits

A low or anteriorly positioned hyoid, or a retruded chin, limits how sharp a cervicomental angle any neck operation can create. Recognising this before surgery protects the patient from an expectation surgery cannot meet, and protects the result from overcorrection. Chin augmentation or genioplasty may be indicated as adjuncts; they are discussed on Day 01 alongside other refinement procedures.

From analysis to a choice

The analysis exists to answer one question: which operation does this neck need?

• Superficial treatment when the excess is mainly subcutaneous and the skin will redrape.
• Platysmaplasty when bands and muscle laxity dominate. See Platysma adaptation after deep neck contouring.
• Deep neck contouring when subplatysmal fat, digastric or gland are responsible, always combined with a plan for the platysma.

Just as important is recognising the patient who needs a different solution entirely, or who would be harmed by doing more. Overresection of central fat and contour irregularities are among the complications covered on the same day.
