In most patients, radix width is properly aligned with the supra-orbital curve and a narrowing procedure is rarely necessary. However, in those rare cases the width of the radix should maintain the natural lines and the balance of the radix with the nasal base. Generally, there is a steady, symmetrical curve arcing from the orbit to the lateral nasal wall. The nearby patient graphic illustrates a normal conjunction between the die supercili ary ridge and the lateral nasal wall; a conjunction which must be preserved during rhino plasty. Should a wedge resection at the radix or comminution and over-mobilization of nasal bones occur, it may result in a narrow or dispro portionate feature that is incongruent with natural facial curves.
A lateral profile of the radix demonstrates how it affects the character of the nose; therefore, the radix must be considered, not as a separate unit, but as a key part of a holistic and dynamic form. Clinically, two elements are substantial: position and anterior projection (height). Both height and position of the radix directly influence each other, from the naso-facial angle to the balance of root to base. Formed by the intersection of the facial plane and the dorsal plane, the naso-facial angle presents at approximately 30 degrees. This angle signifies the visual projection of the nose from the face. What is interesting is that the apparent nasal projection can be changed independently of projection of the tip. Moreover, the apparent projection of the tip can be altered by raising or lowering the radix making the radix serve as the counterpoise of the nasal base.
