A submental incision is a small access point beneath the chin used in selected neck-contouring procedures. Its purpose, length and position depend on what must be treated; it does not guarantee an invisible scar or a sharply defined jawline.
What can be reached through a submental incision?
In facial-rejuvenation surgery, this incision may provide central access to superficial fat, the platysma and selected deeper neck structures. It can be used during a Neck Lift or Deep Neck procedure, but the operation is determined by anatomy rather than by the incision itself.
| Anatomical finding | Possible role of submental access | Limitation |
|---|---|---|
| Superficial submental fat | Cannula access for selected liposuction | Does not correct significant skin or platysma laxity |
| Platysma bands or separation | Central visualization and plication when indicated | Lateral support may also be necessary |
| Subplatysmal fullness | Selected treatment of deep fat or digastric anatomy | Not required in every neck |
| Prominent glands | Assessment and selected partial treatment | Adds salivary, bleeding and nerve-related risks |
| Limited chin or mandibular support | Helps reveal the contribution of soft tissue | Soft-tissue surgery cannot fully change skeletal anatomy |
Submental incision, chin surgery and intraoral access are not interchangeable
Chin implants and osseous genioplasty have their own indications and surgical approaches. Genioplasty is commonly planned through intraoral access by surgeons trained in skeletal surgery; it should not be described as routinely performed through the same small neck-lift incision. The correct access depends on whether the goal involves soft tissue, an implant or bone movement.
Where is the incision placed?
The incision is generally positioned in or near a natural crease beneath the chin, but anatomy, previous scars and the required exposure affect its design. It remains a real cutaneous scar. Early redness, firmness, sensory change or pigmentation may occur, and final maturation can take many months.
Can liposuction alone solve a double chin?
Only when superficial fat is the main problem and skin recoil and platysma are favorable. A full or poorly defined neck may also reflect skin laxity, platysma, subplatysmal fat, digastric muscles, submandibular glands, chin projection, mandibular shape or hyoid position. Removing superficial fat from the wrong patient can reveal deeper fullness rather than improve it.

How Dr. June plans the neck
Dr. June’s cervical assessment extends from the mandibular border toward the lower neck. Depending on anatomy, treatment may combine central platysma plication with lateral traction and selective work beneath the platysma. Deep Neck and partial submandibular-gland treatment are not routine additions.
Risks and limitations
- Hematoma, infection, seroma and delayed healing.
- Visible, widened, raised or pigmented scar.
- Numbness, contour irregularity or asymmetry.
- Nerve weakness, swallowing discomfort or salivary complications in deeper procedures.
- Under-correction, over-correction or need for revision.
Nicotine, excessive tension, previous operations and individual scar biology can affect healing. Medications and supplements should be reviewed with the medical team rather than stopped independently.
Recovery and international care
Swelling, bruising, tightness and temporary numbness are expected early. Rapid swelling, breathing difficulty, increasing pain, fever, drainage, chest pain or shortness of breath requires urgent assessment. Surgery is performed at Hospital São José. International patients generally plan at least 15 days in Brazil after major facial and neck surgery; the concierge team assists with logistics.
The incision is access—not the treatment plan
A small incision can support a carefully selected procedure, but it does not determine the result. The visible contour depends on correctly identifying which layers—and which limitations—are responsible.
