Summary
This study found no direct correlation between six nasal tip projection (NTP) ratios and facial attractiveness. However, certain ratios influenced perceived aesthetics, suggesting their use in rhinoplasty guidelines alongside holistic facial analysis.
Area of Science:
- Plastic Surgery
- Facial Aesthetics
- Anthropometry
Background:
- Established nasal tip projection (NTP) ratios guide clinical practice but lack empirical validation for facial attractiveness.
- Six specific NTP ratios (Goode, Simons, Baum, Powell, Crumley) are commonly referenced.
Purpose of the Study:
- To empirically correlate six landmark NTP ratios with perceived facial attractiveness.
- To identify which NTP ratio, if any, demonstrates the strongest association with overall facial aesthetics.
Main Methods:
- A basic research study involving 300 synthetic lateral facial images of women (ages 18-25).
- Images were created by morphing paired digital portraits and rated by 78 community raters.
- Nasal tip projection ratios were meticulously measured for each portrait.
Main Results:
- No significant correlation was found between the six NTP ratios and overall facial attractiveness.
- Facial attractiveness varied with deviations from ideal ratios; some increased with deviation, others decreased.
- The most attractive faces aligned with ratios previously suggested by expert opinion.
Conclusions:
- This study is the first to empirically link landmark NTP ratios to facial attractiveness.
- While no single ratio correlated directly, Goode and Crumley ratios most significantly impacted facial aesthetics.
- NTP ratios are valuable for rhinoplasty guidelines but should complement comprehensive facial analysis for optimal aesthetic outcomes.

Personality traits are fundamental in shaping social perception and influencing interpersonal relationships. Certain traits, such as agreeableness and extraversion, contribute positively to social interactions, whereas others, such as narcissism, have complex and often contradictory effects on how individuals are perceived over time.The Role of Agreeableness and ExtraversionAgreeableness and extraversion are associated with higher levels of interpersonal attractiveness and likability.
01:24Facial Feedback Hypothesis
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role of...
01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:24Nose and Nasal Cavity
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
