Nasal Anatomy – San Francisco Parts of the Nose

Because there are many internal and external parts of the nose, nasal anatomy is quite complex. It is often difficult to fully grasp. To simplify it, the nose can be seen as having three main parts: the lower third, middle third, and upper third.

In the lower third of the nose, there is the base, the nostrils, and the tip of the nose. The bridge of the nose, also known as the dorsum, makes up the middle and upper thirds.

The nose is composed of soft tissue, bone, and cartilage. The upper third contains bone, the lower third contains cartilage, and in the middle third, the bone and cartilage meet.

Learn more about nasal anatomy and the exact nature of your nasal issues – meet with Dr. Evan Ransom, a double-board-certified surgeon specializing in Facial Plastic and Reconstructive Surgery. To arrange a consultation, contact our office today.
