New insights into tip supporting structures. Consequences for nasal surgery

Knowledge of tip supporting structures is crucial for successful rhinoplastic surgery. The aim of this study was to provide detailed anatomical and histological descriptions of the tip supporting structures.

Serial coronal sections of the entire external noses from seven cadavers were studied after staining by Mallory-Cason and Verhoeff-Van Gieson procedures.

We found no histological evidence of ligaments between the cartilaginous- and bony parts of the nasal skeleton, and between the skin and the nasal skeleton. Instead, we found a perichondrial-periosteal lining within the soft tissue envelope. The main tip supporting and shaping structures are: septal and lobular cartilages, premaxillae, and the soft tissue envelope including the periosteal-perichondrial envelope/membrane. These findings may have clinical relevance in functional and aesthetic rhinoplasties.
