Reducing a dorsal hump or bump on the nasal bridge is commonly undertaken during rhinoplasty surgery. This condition also has a variation which creates the illusion of a significant bump, known as the low radix or pseudo-hump.
The radix refers to the upper bony portion of the nose. The radix, as well as the underlying cartilage, may be substantial causing the appearance of a bump. In case the radix is shallow, it can lead to a depression and a bump. The plastic surgeon can decrease the size of the radix by cautiously shaving away tiny portions.
The plastic surgeon may also use a portion of the patient’s cartilage sourced from another nasal location to add volume to a depressed nasal area. The augmentation of the space right above the radix enables the surgeon to develop a straighter slope.
To create a natural nasal appearance, proper radix management is important. Double board certified plastic surgeon Dr. Geoffrey R. Keyes provides rhinoplasty to patients in Beverly Hills, Los Angeles, Bakersfield, California, and surrounding locations.
A pseudo-hump is a nose in which the radix is insufficiently developed and under-projecting. This creates a facial profile in which the tissue below the radix (towards the nasal tip) seems even more voluminous than it actually is. When the bone of the radix does not project the overlying soft tissue appropriately, it leads to the creation of a pseudo-hump.
Treating an Underdeveloped and Low Radix
Rhinoplasty with radix tissue grafting is the most suitable treatment for an under-projecting radix. A radix graft may comprise fascia, cartilage or other soft tissue. It is usually developed from a carved cartilage fragment (typically sourced from the septum. This graft is then placed underneath the skin and muscle of the nose of the radix where it remains concealed properly.
The deficit in the bony structure is addressed by the placement of the cartilage graft over the bone where it elevates the depressed soft tissue. The outcome of this procedure is a much straighter profile without the need to eliminate any cartilage or bone underneath the radix.
Can you have Weak Radix and a True Hump?
A patient can have an under-developed radix as well as a true hum. The advantage of treating both these issues is that the surgeon can perform a more conservative hump removal.
The ideal profile line is brought nearer to the hump as the position of the radix is elevated. Consequently, the surgeon will have to remove a lesser portion of the hump to create a straighter profile. The outcome of this procedure also appears less “surgical” and more natural due to the more robust nasal starting point.
Correcting Radix as Part of Revision Rhinoplasty
The height of the radix refers to the angle between the frontal and nasal bones of the nose. This height must be proportionate to the length, dorsal height, and tip projection to create balanced, harmonious results.
In case the radix remains too high, or if the radix graft used during the surgery is too large, the nose will appear Romanesque after the procedure. Revision rhinoplasty involves the reduction of the radix to its correct and most appealing proportions in relation to other nasal aspects and the overall facial shape.
