A non-surgical rhinoplasty correction is performed upon a patient under local anaesthesia; the surgeon uses a syringe and a hypodermic needle (e.g. 27-G, 25 mm) to inject and emplace the soft-tissue filler under the nasal skin, most commonly in the deep subcutaneous tissues, and, occasionally, immediately above the (periosteum), in order to correct the nasal defect or deformity, or to achieve the desired modification.
The filler-injection technique makes possible corrections such as the augmentation of a flat nasal bridge (depressed dorsum), the added projection of the nasal tip, correction of retracted columella, small reduction of the nostrils, the camouflage diminution of a nasal hump; the filling of a nasal sidewall depression, the enhancement of a retracted anterior nasal spine, the enhancement of a retracted maxilla lateral to the pyriform (pear-shaped) aperture to displace the anterior plane, the elevation of a saddle nose deformity caused by a failed primary rhinoplasty, and traumatic injury.
The technical procedures for injecting and emplacing the soft-tissue filler require approximately 1-hour to perform;
Indications and technique
Non-surgical correction is indicated for the rhinoplasty patient who presents an innate, treatment-suitable aesthetic defect, or one occurred after a surgical rhinoplasty (either primary or secondary).
The functional and corrective limitations of the soft-tissue-filler medium indicate a surgical correction for the patient whose nasal defect requires extensive anatomic correction that exceeds the (aesthetic) technical scope of filler-injection procedure — which does not increase, nor does it decrease the size of the nose, and does not correct functional defects.
Non-surgical rhinoplasty is more suitable for a majority of patients from Asian ethnic background who mostly seeking augmentation rhinoplasty and it is only suitable for minority of caucasian patients who do not need extensive remodelling of their noses.
