Summary
Forensic facial reconstruction can be improved by understanding skull-nose relationships. This study found nasal width correlates with piriform aperture width, sex, facial type, and age in Brazilians.
Area of Science:
- Forensic Anthropology
- Anatomical Morphology
Background:
- Forensic facial reconstruction relies on skeletal morphology to predict soft tissue features.
- Accurate facial reconstruction requires detailed understanding of craniofacial relationships.
Purpose of the Study:
- To investigate the correlation between alar cartilage, piriform aperture dimensions, and nasal morphology.
- To assess the relationship between these facial features and biological profile characteristics in a Brazilian population.
Main Methods:
- Utilized cone beam computed tomography (CBCT) scans from 96 Brazilian subjects (49 males, 47 females).
- Measured nasal width, alar base insertion distance, and piriform aperture widths (upper and lower) using OsiriX software.
Main Results:
- Nasal width demonstrated a significant association with the lower piriform aperture width.
- Correlations were also found between nasal width and sex, skeletal vertical facial pattern, and age.
- These findings provide population-specific data for forensic facial reconstruction.
Conclusions:
- The study establishes key relationships between nasal and piriform aperture morphology and biological profile indicators.
- This research enhances forensic facial reconstruction guides, particularly for the understudied Brazilian population.

01:08Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
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,...

01:27Cranial 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...

01:22Sutures 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...

01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:24Nose 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...
