Asymmetry in Nasal Bone Structure: Is It Normal? - Orthopedics

Issues related to the nasal bones?


Hello, Doctor! Recently, when I press down along the sides of my nasal bridge with both index fingers starting from the top of the bridge (applying some pressure), I can feel some protrusions on both sides of the nasal bone (although they are not very noticeable externally), with the left side being slightly higher than the right.
The areas where I feel the protrusions are the hard nasal bone locations (not the nasal cartilage).
I would like to ask the doctor why I feel that the nasal bones on both sides are not completely symmetrical (there has been no trauma to that area).
Is it normal for the nasal bones to have slight protrusions on the sides? Thank you, Doctor!

Dr. Shi Guozheng reply Orthopedics


The human skeleton is typically symmetrical, but there can be slight variations, which is considered normal.
If there are any concerns, it is advisable to get an X-ray of the nasal bones for further evaluation.

Understanding asymmetry in nasal bone structure is a common concern among individuals, especially when they notice slight differences in the contour of their nose. The human body, including the nasal structure, is inherently asymmetrical. It is not unusual for one side of the nose to appear slightly different from the other, even in the absence of any trauma or injury.

The nasal bones, which are two small, rectangular bones that form the bridge of the nose, can exhibit variations in size, shape, and position. These variations can be attributed to several factors, including genetics, developmental processes, and even minor environmental influences during growth. Asymmetry can also arise from the natural curvature of the nasal septum, which divides the nasal cavity into two nostrils. If the septum is deviated, it can create an illusion of asymmetry in the nasal bones.

In your case, where you feel a slight elevation on the left side of your nasal bridge compared to the right, it is likely a normal anatomical variation. Many people have subtle differences in their nasal structure that are not noticeable to the naked eye but can be felt upon palpation. This is particularly true for the nasal bones, which can have slight irregularities in their contour.
Moreover, the perception of asymmetry can be influenced by the way we view our own faces. Our self-perception is often skewed by our focus on certain features, leading us to notice asymmetries that may not be as apparent to others. In clinical practice, it is common for patients to express concerns about perceived asymmetries, and upon examination, many find that these variations are within the normal range.

If the asymmetry is not accompanied by any functional issues, such as difficulty breathing or chronic nasal obstruction, it is generally not a cause for concern. However, if you experience any discomfort, pain, or significant changes in your nasal structure, it would be advisable to consult with an Ear, Nose, and Throat (ENT) specialist or a plastic surgeon who specializes in facial aesthetics. They can perform a thorough examination, possibly including imaging studies, to assess the underlying structure of your nasal bones and determine if any intervention is necessary.

In conclusion, slight asymmetries in the nasal bone structure are quite common and typically fall within the realm of normal anatomical variation. If you have no history of trauma and are not experiencing any functional issues, it is likely that what you are feeling is simply a normal characteristic of your nasal anatomy. However, if you have concerns or if the asymmetry is accompanied by other symptoms, seeking professional medical advice would be the best course of action.
