Biomechanics and classification of the cartilaginous structures to project the nasal tip.
The present paper is the long-term conclusion of our preliminary presentation at the 1992 ISAPS Congress (Guadalajara, Mexico). This is the result of 29 cadaver dissections of different ages and both sexes. We have observed that length, thickness, and resistance correlate with the possibility to project the nasal tip with the mere structure of the alar cartilage and its medial crurae. We also demonstrated the existence and antagonistic action of Pitanguy's ligament as well as the depressing ligament to project the nasal tip. In this study, besides focusing on classifying the medial crus according to its thickness, length, and resistance, which is already different from any previous classification, we also focused on its surgical utility, and its interaction with other anatomic elements, to achieve the desired projection. Clinically, we present a 12-year experience with 1653 cases operated under this premise.
