Anthropometric Parameters for Nose Evaluation and Nasal Surgery Planning.

BACKGROUND

The esthetic characteristics of face and nose are commonly evaluated before rhinoplasty using a completely subjective method, due to the lack of validated and reliable methods for quantifying facial esthetics and for accurate nose treatment planning. The aim of the study was to review the literature to determine and evaluate the points, distances, and angles commonly used in the treatment planning for rhinoplasty.

METHODS

Research based on anthropometric studies of the face and nose, published from 1987 to 2018 was included. Finally, 138 papers were selected after a statistical analysis through a simple random and non-random sample selection, and all papers were evaluated in their entirety.

RESULTS

According to the frequency of citation, 198 points, 336 distances, and 199 angles were listed. The first quartile of each distribution was eliminated, and frequency of more than 25% was selected. A group of 49 points, 77 distances, and 11 angles, were classified according to their anatomical region, that is, bone and soft tissues, was obtained.

CONCLUSIONS

An enormous inhomogeneity and lack of standardized anthropometric measurement system, specifically of the nose, was evident, as the studies were conducted by authors of different origins. According to universally accepted parameters, the importance of a reliable method for nose surgery planning is highlighted.
