An Innovative Approach for Nasal Reshaping using Hyaluronic Acid Intradermal Injections.

Background: Nasal reshaping using hyaluronic acid (HA) filler has become a widespread technique and injections are usually performed in deep layers. As an alternative, we propose an innovative approach where HA is injected into the dermis, the so called MesoRhinoFiller.

Aims and objectives: The aim of this study was to describe our injection technique using a smooth, cohesive, and slightly viscous HA filler injected in the dermis.

Materials and methods: A retrospective review of the author's clinical experience from March 2017 to March 2020 was presented. A total of 280 consecutive patients were treated with HA injections to improve their nasal appearance. The mean volume was 0.5 cc HA filler/treatment.

Results: An average increase of 4.9 ± 3.4° was obtained for the nasofrontal angle, and of 7.0 ± 4.5° for the columella labial angle. Asymmetries in the nasal profile and alar rim were also corrected. All the patients were satisfied with the results and no complications occurred.

Conclusion: Injecting HA fillers in the dermal plane is a versatile approach that provides very satisfactory results. This technique allows one to better correct aesthetical, post-traumatic, and post-surgical defects compared with the usual injection rhinoplasty procedures where the filler is injected deep onto the bone/cartilage in the midline of the nose.
