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...

Summary

This study found slight nasal asymmetry in healthy adults, with moderate relationships between nostril and alar dimensions and areas. Detailed nostril assessments are necessary for accurate evaluation.

Area of Science:

Anatomy
Anthropometry
Facial morphology

Background:

Facial asymmetry is common, but detailed nasal base morphology in healthy young adults requires further investigation.
Understanding nasal dimensions and asymmetry is crucial for reconstructive surgery and anthropometric studies.

Purpose of the Study:

To evaluate directional and fluctuating asymmetry in the nasal base of healthy young adults.
To measure nostril area and its relationship with the cutaneous nasal area.

Main Methods:

Utilized 3D plaster models of 20 healthy adults' noses.
Reconstructed nasal models using Non-Uniform Rational B-Splines (NURBS) for precise measurements.
Computed linear distances, angles, and surface areas of nasal structures.

Main Results:

Left nasal structures were slightly larger than right-side counterparts (P<0.05).
Nostril axis length was approximately 60% of alar length.
Nostril area constituted about 3% of the cutaneous nasal area.

Conclusions:

The employed method allows for simple nasal base dimension and asymmetry measurements.
Slight asymmetry was observed even in healthy individuals.
Moderate correlations between nostril/alar dimensions and areas highlight the need for detailed nostril analysis.
