A “double chin” is a visual description, not an anatomical diagnosis. Fullness beneath the chin may come from superficial fat, loose skin, platysma, deep fat, digastric muscles, submandibular glands, limited chin projection or hyoid position. The least extensive operation that addresses the responsible structures is usually the most coherent plan.

Diagnosis comes before choosing a procedure

Examination reviews skin elasticity, superficial and deep fat, platysmal bands, jawline laxity, gland prominence, chin projection and neck length. Weight history matters because liposuction is not weight treatment and later weight change can alter the contour.

FindingPossible approachWhat it cannot do
Localized superficial fat with elastic skinSubmental liposuctionRepair platysma or treat deep fullness
Platysmal bands or skin laxityPlatysmaplasty and/or Neck LiftChange the skeleton or hyoid position
Meaningful subplatysmal fullnessSelected Deep Neck treatmentGuarantee a sharply defined jawline
Limited chin projectionAssessment of skeletal supportRemove every soft-tissue contributor

Procedures can be combined, but treating every layer is not an objective. A simpler operation may be more appropriate when it solves the diagnosed problem with less dissection.

When liposuction is—and is not—enough

Submental liposuction works best when superficial fat is the main concern and skin can retract adequately. It does not correct platysmal separation, deep fat, a prominent gland or limited chin projection. Removing too much superficial fat can reveal bands or create irregularity.

A large series of 987 neck liposuction procedures reported few nerve injuries and other complications, but later reviews document seroma, contour irregularity, platysmal banding and uncommon serious events. These findings reinforce careful selection rather than the assumption that a smaller incision means negligible risk.

Neck Lift and Deep Neck are different operations

A Neck Lift may combine superficial fat treatment, central platysma repair, lateral support and skin redraping. When indicated, Dr. June may use central plication with lateral traction rather than removing central neck skin.

Deep Neck surgery adds access beneath the platysma. It may address selected subplatysmal fat, digastric muscle or submandibular-gland prominence. A systematic review found substantial variation in which deep structures surgeons treat, so the term does not describe one standardized operation.

Submandibular-gland reduction is optional

Partial gland reduction should not be routine. Potential contour improvement must be weighed against bleeding, hematoma, salivary leak or sialocele, dry-mouth symptoms, contour change and nerve-related lower-lip weakness. The patient may decline this step even when gland prominence limits the result.

Bone and hyoid position set limits

A small or retruded chin can make an otherwise normal neck appear fuller. A low or anterior hyoid can limit the cervicomental angle. Soft-tissue surgery cannot relocate every skeletal or airway-related structure, and a “perfect 90-degree angle” is not a responsible promise.

Previous procedures and ultrasound

Fillers, biostimulators, threads, PMMA, silicone and device treatments near the jawline or neck must be disclosed. Dermatologic ultrasound may help map material, fluid or fibrosis when the history is uncertain. It is useful selectively, not automatically.

Risks and realistic recovery

Risks include bleeding, hematoma, infection, seroma, contour irregularity, asymmetry, skin compromise, altered sensation, marginal mandibular weakness, salivary complications, visible scars, thrombosis, anesthetic events and revision. The risk profile rises as the operation extends into deeper structures.

Swelling, bruising, tightness, temporary numbness and firmness can last for weeks. Deeper swelling and scar maturation may continue for months. The early contour is not the final result, and postoperative compression should follow the surgical team’s instructions rather than a generic protocol.

Planning from abroad

Video consultation can begin the assessment, but the definitive plan follows an in-person examination. Surgery is performed in a hospital with anesthesiology and postoperative monitoring. International patients generally arrive in Criciúma one or two days before surgery and remain at least 15 days after a major cervical procedure, adjusted to recovery.

Questions that determine the operation

  • Is fullness superficial, deep, muscular, glandular or skeletal?
  • Will skin retract after fat removal?
  • Which structures would remain untreated?
  • What added benefit and risk comes from Deep Neck surgery?
  • Which anatomical limit will remain even after surgery?
