A narrative-style review of non-surgical rhinoplasty: Indications, outcomes, and limitations

The aim of this narrative-style review was to evaluate non-surgical rhinoplasty in terms of indications, outcomes, and limitations. Both 'PubMed' and 'Science Direct' were reviewed by all authors, in order to reach consensus with regard to the chosen studies. Studies published from 1980 to 2023 were searched using the key terms "non-surgical rhinoplasty", "dermal filler", "thread lifting", and "botulinum toxin", and relevant papers were selected. Non-surgical rhinoplasty refers to the use of injectable temporary fillers to augment selected areas of the nose, in order to achieve improved appearance or function in select patients. It includes the use of dermal fillers, thread lifting, and botulinum toxin injections. The perfect dermal filler would be inexpensive, safe, painless to inject, hypoallergenic, and long lasting. In addition, it should produce consistent and predictable results, feel natural under the skin, take little time to inject, be ready to use, exert no downtime on the patient, and have a low risk of complications. Regions of the nose treated with filler injections include the frontonasal angle, dorsum, nasolabial angle, and columella. Thread lifting and botulinum toxin injection are the other methods of non-surgical rhinoplasty. Dermal fillers, thread lifting, and botulinum toxin injections can be used as non-surgical rhinoplasty. Dermal fillers and botulinum neurotoxin can be used alongside each other to allow minimally invasive resculpting of the nasal region and midface, compensating for a reduction in tissue volume and the formation of rhytides.
