What is the perfect nose?
Beauty and explaining fundamental characteristics that make someone viewed as lovely has long captivated mankind. The nose, being the most prominent feature of the face, plays an important part in determining the face’s overall balance and proportion. It should blend in with the other features of the face and allow them to stand out. Many criteria and ratios have been offered in an attempt to quantitatively quantify the ‘ideal’ nose, dating back to ancient Greece. As the practice of facial aesthetics, including rhinoplasty, has grown exponentially in recent years, these geometrical laws have been used to aid in achieving the optimum cosmetic result . The goal of this narrative review is to look at the numerous canons presented in the literature in order to figure out what a ‘perfect’ nose looks like from an aesthetic standpoint.
The nose’s anatomy and function
The nasal root is positioned cranially and is continuous with the forehead, giving the nose a pyramidal shape. The nasal tip is located below the apex of the nose. The root and tip of the nose are connected by the dorsum. The nasal septum divides the two nasal airways and creates the central strut of the nose. The upper third of the nose is made up of a pair of nasal bones, while the middle third is made up of stiffer paired upper lateral cartilages (ULC), which provide structural support for the septum by their attachment to the nasal bones. A pair of softer lower lateral cartilages make up the lower third (LLC). The LLC is fragile, relying on the ULC for support. The nasal bones and the LLC have an overlap; if they separate, the center part of the nose might collapse, creating nasal blockage and an unattractive outward appearance (2). As the nasal valve area, the middle and lower thirds of the nose play an important role.
Thirds on the horizontal plane
Da Vinci divided the face into equal horizontal thirds in his books on human anatomy (Figure 1). From the trichion (midpoint of the hairline) to the glabella, the upper third is measured (area above the nose and between the eyebrows). From the glabella to the subnasale, the middle third is measured (where nasalseptum meets the upper lip). From the subnasale to the menton, the bottom third is measured (most inferior point of the chin). The optimum nose surgery should be proportional to the midface, as the nose occupies the middle third of the face. This has been suggested as 0.67 times the midfacial height (9). Photographs of Caucasian female celebrities (actresses and models) were compared to a sample of nameless Caucasian girls from the general community by Milutinovic et al.
The Golden Ratio is a mathematical formula that
The artist Parthenon Phidias named it Phi, and it is an irrational number with a value of 1.618. The Fibonacci ratio, or ‘divine proportions,’ is another name for it. The golden ratio is a naturally occurring proportion that is commonly employed in architecture and art, as well as in facial aesthetics. This ratio is thought to be aesthetically attractive to the eye, and our brains instinctively associate it with the concept of beauty. Many facial proportions have been given this value. It also specifies the appropriate mouth-to-nose width ratio.
