It's not just the E-Line! What is the ”neck-jaw angle,” the key to a beautiful profile?
A dual-specialty doctor with a background in plastic surgery, bridging cosmetic surgery and ophthalmology. At the university hospital, he performed numerous high-difficulty cases, primarily focusing on eye and facial bone surgeries, cultivating precise techniques grounded in anatomy. He prioritizes achieving both aesthetic beauty and functional safety, offering customized treatments around the eyes that incorporate ophthalmological expertise. He actively utilizes not only incisional surgery but also non-invasive procedures like hyaluronic acid injections. By carefully assessing each individual's condition and unique appeal, he provides bespoke treatments that guide patients toward naturally harmonious, well-defined eyes.
Hello,Image Designer/Plastic Surgeon Ryutaro Natsumeis

A beautiful profile conveys an impression of sophistication.
Previously, we introduced the E-Line as a key factor for a beautiful profile. This time, we'll cover the ”neck-jaw angle” and its treatment methods!

As a review,
The line connecting the tip of the nose, upper lip, and chin is called the E-Line and is considered a beautiful contour.

(Left: Before treatment, Right: Immediately after hyaluronic acid treatment on nose/chin)
We design while considering the overall facial balance, determining which areas to enhance—the nose, lips, or jawline.

The key to a beautiful profile: the ”cervicomental angle” Medically termed the cervicomental angle.

”The ”cervicomental angle" is the medical term for the angle between the neck and the lower jaw. The ideal range is 105-120 degrees.
In the case of a so-called double chin, the ”neck-chin angle” becomes wider than the ideal.
The reason why many Japanese people have double chins is often due to skeletal structure or bite alignment, so orthodontic treatment may improve it.
(Check out my past blog post "Why Do I Have a Double Chin Even Though I'm Not Overweight? Explaining the Causes and Treatments.")https://biancaclinic.jp/blog/43545/)
However, if there is a significant amount of fat under the chin, it becomes difficult to achieve the ideal ”neck-chin angle,” so submental liposuction is performed.
Recently, many people seek ”localized fat reduction” to achieve a more refined silhouette, even if they don't have excessive body fat overall.
When skin laxity is severe, using tightening devices like FaceTite or Morpheus in combination can be effective.

I'm curiousDowntime, pain, safety
・Downtime:
Most patients who perform desk work return to work the day after surgery. Makeup, facial cleansing, and showering are possible the day after surgery, allowing you to resume your normal daily activities.
For those in customer service or sales roles, we recommend resting for about three days as a precaution.
For the first 72 hours after surgery, when swelling is most likely to occur, you will need to wear a removable compression bandage called a face band.
Wearing a hat and mask makes you almost unnoticeable.For those in professions where masks are not an option, you may be concerned about bruising, so we recommend covering it up with concealer.
Swelling and bruising will improve within about 7 days.
・Pain:You will experience minimal pain as you will be asleep under intravenous anesthesia. After returning home, you can comfortably manage any discomfort with oral pain medication.
・Safety:When local anesthetic with hemostatic properties is sprayed into the correct fat layer and liposuction is performed at the correct layer, the risk is low.
Utilizing the anatomical knowledge and techniques learned in plastic surgery, we provide safe procedures. If you are concerned about post-operative hematomas, we recommend combining with FaceTite. FaceTite is similar to HIFU, where energy is delivered directly into the subcutaneous layer. It provides strong skin tightening effects through thermal coagulation. By applying heat, it also cauterizes fine blood vessels, reducing the risk of post-operative bleeding.

Summary
This time, we introduced the ”cervicomental angle,” a key factor in achieving a beautiful profile.
Submental liposuction with shorter downtime than expected is recommended!
