Dorsum nasi
Dorsum Nasi
The Dorsum Nasi (pronounced: dor-sum na-zi) is a term used in anatomy to refer to the length of the nose from the root at the frontonasal suture to the apex or tip of the nose.
Etymology
The term "Dorsum Nasi" is derived from Latin, where "Dorsum" means back and "Nasi" refers to the nose. Thus, it literally translates to "back of the nose".
Anatomy
The Dorsum Nasi is the vertical ridge in the middle of the human nose. It is made up of both bone and cartilage. The upper third is formed by the nasal bones, and the lower two-thirds are formed by the lateral nasal cartilages and the greater alar cartilages.
The Dorsum Nasi is an important feature in rhinoplasty, a type of plastic surgery that changes the shape of the nose. It is also a significant landmark in the assessment of the nasal profile in both normal and abnormal conditions.
