In the past 20 years the anatomy of the nose and the resulting static pillars were more intensely analysed and increasingly considered when planing for an operation.
The stability of the bony frame is guaranteed by 3 pillars:
The tip of the nose is stabilised by cartilaginous pillars:
With the help of a DVT (digital volume tomography, also: cone beam computer tomogrphy, CBTC in short) a diagnostic imaging of the inner anatomy of the nose can be performed. Compared to CT-imaging one achieves a significantly higher imaging resulation with decreased radiation.
The assessment of the nasal septum, the nasal turbinates and the complex structure of the paranasal sinuses is a prerequisite to plan a functional septorhinoplasty.
