Non-surgical rhinoplasty using hyaluronic acid dermal fillers: A systematic review.

[BACKGROUND] Non-surgical rhinoplasty using hyaluronic acid dermal fillers is a cosmetic procedure that has been becoming increasingly popular among patients wanting to correct nasal deformities or nasal irregularities, in the recent years.

[AIM] This systematic review aims to provide quality evidence about the success of non-surgical rhinoplasty procedures in terms of patient satisfaction and complications.

[METHODS] A systematic electronic literature search using keywords and MESH search terms over the PubMed/Medline, Cochrane Central, Scopus, and EBSCO online databases was conducted from November 2005 to February 2021. Additionally, the reference lists of included systematic reviews were hand searched. Data collected included patient satisfaction and complications from prospective and experimental studies providing highest level of evidence. Articles were critically appraised, and MINORS scale was used to assess the risk of bias.

[RESULTS] Based on the search criteria, 2896 citations were found. After removing duplicates and screening for relevance, 23 citations were finalized for full-text review, of which 12 articles were excluded and 11 articles were included in the study. The average satisfaction of patients amongst the studies was found to be >90%. In all the studies, transient edema and erythema, post-injection pain, and bruising were some temporary complications. Rare complications that were reported were vascular impairments and hematoma.

[CONCLUSIONS] Non-surgical rhinoplasty is a good, minimally invasive alternative over conventional rhinoplasty. There is however a paucity of quality data in the form of experimental and prospective studies regarding the accuracy, effectiveness, and complications of non-surgical rhinoplasty.
