A “double chin” is a description, not a diagnosis. Fullness beneath the chin can come from superficial fat, deep fat, skin laxity, platysma, submandibular glands, limited chin projection or hyoid position. The correct treatment depends on which structures create the contour—not on choosing the most extensive procedure.
Why the cervicomental angle varies
The angle between the underside of the chin and the neck is influenced by soft tissue and skeleton. Weight loss or liposuction may reduce superficial fat but cannot change bone projection or hyoid anatomy. A naturally obtuse angle therefore cannot always be transformed into a sharply defined one without considering these limits.
Choosing between available procedures
Submental liposuction
Best suited to selected patients with localized superficial fat and good skin elasticity. It does not repair platysma or treat deeper structures.
Platysmaplasty and neck lift
Central repair can improve visible bands, while lateral support and skin redraping may be needed when laxity extends toward the jawline. Not every patient requires both.
Deep Neck surgery
May address subplatysmal fat, selected digastric anatomy, ligaments or gland prominence. It is reserved for patients whose deep structures meaningfully contribute to fullness.
Chin projection
When mandibular retrusion is important, chin augmentation or another skeletal strategy may be discussed. Soft-tissue removal alone may not create the desired profile.
Submandibular gland treatment
Partial gland reduction is optional, not routine. It may improve lateral neck contour in selected patients, but carries risks including bleeding, hematoma, sialocele, salivary changes, dry-mouth symptoms and nerve-related alteration of the smile. The patient may decline this step even when it could improve contour.
What results are realistic?
The goal is improvement in proportion and definition, not a guaranteed “perfect jawline.” Skin quality, skeletal anatomy, tissue thickness, scars and healing determine the achievable change. More surgery is not necessarily better, and Deep Neck is not universally superior to a well-indicated simpler procedure.
Risks and recovery
Risks include:
- Bleeding, infection or seroma
- Contour irregularity or asymmetry
- Altered sensation or skin compromise
- Lower-lip weakness
- Salivary complications
- Visible scars
- The possibility of revision surgery
Swelling and firmness can persist for weeks or months, especially after deeper treatment.
Frequently Asked Questions
Is Deep Neck surgery always the best option?
No. Deep Neck surgery is reserved for patients whose deep structures meaningfully contribute to fullness. A well-indicated simpler procedure, such as submental liposuction or platysmaplasty, can be the right choice for other patients.
Can liposuction alone fix a double chin?
Only in selected patients with localized superficial fat and good skin elasticity. It does not repair platysma bands or treat deeper structures beneath the muscle.
Will surgery guarantee a sharply defined jawline?
No. Skeletal anatomy and hyoid position set limits that soft-tissue procedures cannot fully overcome, so results are evaluated in terms of realistic improvement rather than a guaranteed outcome.
International patients
Planning starts by video with photographs, medical history and details of previous fillers, threads or devices. Dermatologic ultrasound may be required. Patients generally arrive in Criciúma one or two days before surgery and stay at least 15 days for hospital-based care and follow-up before flight clearance.
