A normal head shape, also known as normocephaly, generally resembles an egg when viewed from above.
Defining Normocephaly
Normocephaly is a term used to describe a head that's considered within the normal range for size and shape. Here’s a breakdown of what constitutes a "normal" head shape:
- Shape: Should appear similar to an egg when viewed from above. This means it's slightly wider at the back than at the front.
- Proportions: Ideally, the head is thought to be about 20% longer than it is wide.
- Symmetry: A normal head shape should be symmetrical, meaning there isn't a significant difference between the left and right sides.
Key Characteristics of a Normal Head Shape
Feature | Description |
---|---|
Overall Shape | Egg-like when viewed from above, wider at the back |
Proportions | Approximately 20% longer than it is wide |
Symmetry | No significant asymmetry or difference between the left and right sides |
Important Considerations
While the above describes an "ideal" normal head shape, it's important to remember that natural variation exists. Slight deviations from these measurements or proportions don't necessarily indicate a problem. However, noticeable asymmetry or unusual head shapes should be evaluated by a healthcare professional.
