This study defines new terms for nasal bone anatomy, revealing distinct "S-shape" and "V-shape" configurations. Understanding these nasal bone shapes aids surgeons in planning rhinoplasty procedures.
Area of Science:
- Anatomy
- Anthropometry
- Plastic Surgery
Background:
- Nasal bone analysis is crucial for both functional and aesthetic outcomes.
- Existing anatomical parameters for nasal bones are insufficient for precise measurements.
Purpose of the Study:
- To establish new descriptions, terms, and definitions for nasal bone anatomy.
- To harmonize anthropometric and clinical measurements through adequate terminology.
Main Methods:
- A two-part harvest technique was used on 44 cadavers.
- Specimens were resected, and skull replicas were created for measurement.
Main Results:
- Nasal bones exhibit irregular shapes with three distinct angles: nasion angle (NA), dorsal profile angulation (DPA), and kyphion angulation (KA).
- 88% of cases showed an angulated caudal portion, forming an "S-shape" nasal bone configuration.
- 12% of cases presented a straight caudal portion, resulting in a "V-shape" configuration.
Conclusions:
- Standardizing nasal landmarks and understanding bone configurations improve surgical planning.
- This research aids rhinoplasty surgeons in operating on the radix and osseocartilaginous vaults.

Cranial Bones: Lateral View
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...

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
