Men exhibit distinct craniofacial measurements compared to women, with significant differences observed in auditory tube and nasopharynx dimensions. These sex-based variations in craniofacial morphology persist into adulthood.
Area of Science:
- Anthropology
- Anatomy
- Radiology
Background:
- Craniofacial morphology exhibits variations across populations and sexes.
- Understanding sex-based differences in craniofacial parameters is crucial for accurate clinical and research applications.
Purpose of the Study:
- To compare normal adult male and female craniofacial parameters.
- To evaluate the associations of sex and intercochlear distance with other craniofacial parameters.
Main Methods:
- Retrospective analysis of two-dimensional computed tomography scans from 60 normal adults (30 men, 30 women).
- Measurement of various craniofacial parameters, including auditory tube dimensions, mastoid length, intercochlear distance, and nasopharynx sagittal area.
- Assessment of Körner septum presence and thickness.
Main Results:
- Men demonstrated significantly greater mean lengths of the osseous and cartilaginous auditory tubes, mastoid length, and intercochlear distance compared to women.
- Men also showed larger sella to posterior nasal spine distance, sella to basion distance, and nasopharynx sagittal area.
- Intercochlear distance correlated with mastoid depth, pharyngeal opening distance, sella to nasion distance, and nasopharynx sagittal area, while inversely correlating with the auditory tube angle. Körner septum was more frequent and thicker in men.
Conclusions:
- Significant sex-based differences exist in several craniofacial parameters, particularly vertical dimensions, starting from childhood and continuing into adulthood.
- These findings underscore the importance of considering sex in craniofacial morphologic studies.
- Results from studies lacking sex-matched groups should be interpreted with caution.

Overview of the Skull
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...
Sutures of the Skull
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...
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,...
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...
Introduction to the Skeletal System
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
