Nasal dorsum

Nasal Dorsum

The nasal dorsum is the anatomical term for the vertical ridge of the nose, often referred to as the bridge of the nose. It is a central feature of the facial anatomy, playing a significant role in determining the aesthetic appearance and character of the face. The structure and shape of the nasal dorsum can vary greatly among individuals, influenced by genetic, racial, and ethnic factors.

Anatomy

The nasal dorsum extends from the root of the nose, at the junction between the forehead and the nose, down to the tip of the nose. It is formed by the underlying bones and cartilages, specifically the nasal bones at the upper part and the upper lateral cartilages and the septal cartilage at the lower part. The skin covering the nasal dorsum is relatively thin compared to other parts of the face, allowing the underlying structures to influence the contour and appearance of the nose prominently.

Function

The primary function of the nasal dorsum, along with the rest of the nasal structure, is to facilitate breathing by supporting the nasal passages. It also plays a crucial role in protecting the sensitive internal components of the nasal cavity. Aesthetically, the nasal dorsum contributes to the overall symmetry and balance of the face.

Clinical Significance

Alterations in the shape or size of the nasal dorsum can arise from congenital conditions, trauma, or previous surgical interventions. Conditions such as a deviated septum can affect the alignment of the nasal dorsum, leading to functional and aesthetic issues. Cosmetic and reconstructive surgeries, such as rhinoplasty, often address concerns related to the nasal dorsum to improve nasal function and facial harmony.

Rhinoplasty

Rhinoplasty is a surgical procedure aimed at reshaping the nose. Modifications to the nasal dorsum, including reducing a hump, straightening, or altering the height, are common objectives of this surgery. Rhinoplasty can be performed for both cosmetic reasons and to correct functional impairments.

Cultural and Aesthetic Considerations

The perception of an ideal nasal dorsum varies widely across different cultures and individual preferences. Some may prefer a straight and narrow dorsum, while others may find a slight curvature or a more pronounced dorsum to be desirable. Understanding these aesthetic ideals is crucial for surgeons performing nasal surgeries to ensure that the outcomes meet the patients' expectations while maintaining functionality.
