Abstract

Background:

Accessory cartilages are small nasal cartilages between the lateral crus and piriform aperture of the nose bilaterally. These cartilages are among the supporting structures of the nasal tip.

Study Design:

This prospective cross-sectional study was conducted on Iranian fresh cadavers for evaluation of ethnic differences. Seventy-two sesamoid cartilages in 41 cadavers (mean age 42 years) were dissected to evaluate anatomy and anthropometry of the sesamoid cartilages. Elevation of the dorsal nasal flap after a collumellar incision was done. After the separation of the lower lateral cartilages and sesamoid cartilages on each side, the anatomy and anthropometry of the cartilages were assessed.

Results:

In 12% (5) of the cadavers there were no sesamoid cartilages, and in 88% (36) of the cadavers there was 1 sesamoid on each side. The shape of the sesamoid cartilages was rectangular in 66% (27) and triangular in 22% (9). The mean length, width, and thickness were 3 mm, 2 mm, and 0.75 mm, respectively.

Conclusions:

This cartilage was single on each side of the nose and its shape was an irregular rectangle or triangle and has an important role in preserving nasal alar contour and tip projection. These findings confirm ethnic variations in the sesamoid nasal cartilages when this Iranian population is compared with other populations assessed in earlier reports.

Cranial Bones: Lateral View

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Nose and Nasal Cavity

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Classification of Bones

Classification of Bones

The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The long...

Sutures of the Skull

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
