Nose injections are especially effective in nasal deformities with deficiencies, where the addition of filler by injection serves to conceal the deformity. A low nasal bridge and small nasal hump are classic deformities that respond well to nose injections. In contrast, patients with deformities arising from excess dimensions such as a bulbous tip and wide nasal base are poor responders to non-surgical rhinoplasty. Adding filler material by nose injection will exacerbate the preexisting excessive dimension. These noses can only benefit from the surgical reduction of tissue to reduce its excessive dimension. Patients with nasal asymmetry, thick skin, and scarred skin also do not respond well to nose injections.
