Nasal Radix Augmentation With Temporalis/Mastoid Fascia Harvested Through Postauricular Approach
The Problem
Shallow nasal radix.
The Background
One of the relatively common anatomical variations is a deficient nasal radix. Radix augmentation is therefore a common procedure in rhinoplasty that has significant effects on patient aesthetics. In 1996, Skoog reported using a resected dorsal hump as an autograft for the correction of an overly resected hump and a shallow radix. The resected hump can be displaced superiorly into the deep nasal root. In cases where a dorsal hump is not being resected or that there is not enough resected tissue, the deficiency needs to be augmented using other methods. Potential autografts include diced or crushed septal, conchal, or rib cartilage. Furthermore, wrapping the autograft with Surgicel, amniotic membrane, or fascia will potentially prevent formation of palpable tiny particles under the thin skin especially with diced cartilage. The temporalis and mastoid fascia are important graft reservoirs for facial and nasal augmentation procedures.
