Your Chin to Neck Angle and Your Airway

Updated: Jun 1, 2023

The chin to neck angle refers to the position of the chin in relation to the neck. It plays a crucial role in airway patency and can have a significant impact on breathing and airway function. Individuals with a poorly positioned chin often have a small or recessed mandible, which can cause the airway to become partially obstructed. This can lead to a number of breathing problems, including sleep apnea, snoring, and mouth breathing.


A poor angle or a double chin, also known as submental fullness, is a common cosmetic concern. It can be caused by factors such as weight gain, aging, genetics, and poor posture. A double chin can affect a person's appearance and self-esteem. But worse, it can affect the airway. In some cases, it may be treated through cosmetic procedures such as liposuction, injections, or neck lift surgery. However, the best approach might depend on the underlying cause and the individual's bone structure, and double jaw surgery should be explored as an option. Especially today since it is less invasive and the surgery times are improving everyday.


A double chin and/or a poor angle can occur in individuals who are not overweight. While being overweight can increase the likelihood of having a poor angle, there are other factors that can contribute to its development, such as genetics, aging, and poor posture. As we age, the skin and muscles in the neck and chin area can lose elasticity, causing the skin to sag and the fat to accumulate. This is why sleep apnea can effect someone from any demographic, and can worsen with age.



The chin to neck angle is an important aspect of facial anatomy that can affect breathing and airway function since, in individuals with a poorly positioned chin, the airway can become partially obstructed, leading to a number of respiratory issues, including OSA, snoring, and mouth breathing. To address these problems, custom 3D printed titanium plates and double jaw surgery have been developed as treatments to improve the chin to neck angle and provide better breathing.


Custom 3D printed titanium plates utilized by Alfi Oral Surgery are designed to improve the chin to neck angle and correct airway problems by moving the jaws forward. These plates are designed using three-dimensional imaging software and manufactured using computer-aided design and computer-aided manufacturing technology. The plates are customized to the individual's anatomy, ensuring that they are tailored to their specific needs. During the surgical procedure, the plates are positioned on the jaws to bring them into a healthier position, providing a more optimal chin to neck angle.


This procedure is used to correct airway problems caused by a poorly positioned chin, as well as other jaw and dental anomalies. The surgery involves making incisions in both the maxilla and mandible, and then repositioning the bones to improve the chin to neck angle. This AOS procedure can provide better airway function and can improve breathing and sleep patterns.
