Augmenting the radix is an indispensable asset to established surgical techniques when correcting the nasal dorsal profile. In selected patients, lowering the dorsum by a hump resection in combination with raising the nasion to straighten the dorsal profile may yield more aesthetically pleasing results with a strong dorsal profile line compared with lowering the dorsum to the level of the nasion.1 Patients with thin dorsal skin and narrow middle third of the dorsum in particular are at increased risk for visible irregularities after a hump resection and osteotomies. In these patients, straightening the dorsum by augmenting the radix in combination with partially reducing a hump by rasping may be considered a viable alternative to a classic hump resection. The latter typically requires osteotomies and often measures to preserve the width of the middle third of the dorsum, adding complexity to the procedure.
