Thyroid cartilage (Adam's apple): a neck reference point
Quick facts
- Definition
- The largest cartilage of the larynx, made of two plates that join at the front of the neck.
- Adam's apple
- The prominence where the plates meet, more noticeable in men.
- Position
- Just below the hyoid bone, on the midline of the neck.
- Relevance in HOF
- A reference for proportion and for the lower limit of the neck and cervicomental angle assessment.
The thyroid cartilage is the largest cartilage of the larynx. It is made of two plates that meet at the midline, at the front of the neck. The point where they meet forms a bump: the Adam's apple. It sits just below the hyoid bone, and above it lies the chin area and the angle between chin and neck.
Why is there a difference between men and women?
The two plates join at different angles. In men the angle is sharper, close to 90 degrees, and the prominence is more visible. In women it is wider, close to 120 degrees, and the neck looks smoother. The difference appears at puberty, driven by hormones, and is one of the traits patients associate with gender. In trans patients or those going through gender affirmation, the neck may be part of the concern.
How does it factor into facial assessment?
The thyroid cartilage works as a palpable landmark on the midline. Together with the cervicomental angle, it helps describe the relationship between chin, neck, and larynx. When looking at the facial profile, the professional observes the definition of the submental area, the presence of a double chin or submental fat, and the action of the platysma.
What care is needed?
The front of the neck holds delicate structures, such as the larynx, thyroid, and blood vessels. It is not a place for injection without specific training. Neck assessment in HOF is usually done to plan the chin and jawline, and any procedures in this area are a decision for the qualified professional, following the rules of their professional council.
In Harmy
Harmy works with the frontal photo and the Chin and Jawline points. It does not analyze the neck or the profile, so the thyroid cartilage falls outside what the app simulates.
Frequently asked questions
What is the Adam's apple?
It is the prominence formed where the two plates of the thyroid cartilage meet, at the front of the throat. It is generally more pronounced in men.
Why does the thyroid cartilage matter in a neck assessment?
It serves as a midline reference for judging proportions, the angle between chin and neck, and differences between the sexes.
