Commentary on: The Impact of Facial Asymmetry on the Surgical Outcome of Crooked Nose: A Case Control Study

Consensus Recommendations for the Reconstitution and Aesthetic Use of Poly-D,L-Lactic Acid Microspheres

Poly-D,L-lactic acid (PDLLA) microspheres, marketed globally as Aesthefill® (Regen Biotech, Seoul, South Korea), are recognized for their biocompatible and biostimulatory properties, positioning them as a preferred option in aesthetic medicine. This article presents consensus recommendations from Brazilian experts on the reconstitution and clinical application of PDLLA for facial and non-facial treatments. Developed using a modified Delphi method with contributions from leading dermatologists and plastic surgeons, the consensus outlines protocols for reconstitution, injection techniques, and patient management. Key recommendations include reconstitution with 7-8 mL of sterile water for injection, the addition of lidocaine to improve patient comfort, and a preference for targeting the superficial subcutaneous layer. Dosing guidelines are specifically tailored to each treatment area and the desired degree of correction, underscoring the importance of personalized treatment plans. Maintenance treatments are advised at biennial intervals or at shorter intervals for patients exhibiting accelerated collagen degradation. The consensus also highlights the need for proper training and patient screening to minimize adverse effects, such as nodules and granulomas. This comprehensive guide aims to standardize the use of PDLLA, prioritizing patient safety and optimizing outcomes. While clinical trials evaluating PDLLA's aesthetic indications remain limited, these evidence-based guidelines bridge the gap by offering practical protocols grounded in clinical expertise. Further research is encouraged to validate these recommendations and explore new applications for PDLLA in aesthetic medicine.

Prevalence of Facial Asymmetry and Correction Methods for Rhinoplasty in Individuals with Deviated Nose: A Brief Review

Background:

Surgeons frequently perform rhinoplasty on individuals who have facial asymmetry. Patients’ discontent following rhinoplasty has been linked to facial asymmetry. On the other hand, correction of a deviated nose is a tough procedure, and it is not the same as septal deviation correction. Surgeons, who often perform rhinoplasty for deviated nose in people with asymmetrical faces, focus primarily on correcting nasal defects and overlook such facial asymmetry.

Aim:

We aimed to summarize and review the prevalence of facial asymmetry in patients subjected for rhinoplasty for deviated nose correction.

Methods:

A systematic search was conducted covering PubMed, Scopus, ISI, and Google Scholar using related key words and MeSH (Medical Subject Headings) terms from 2000 until November 2021 for English published articles.

Results:

The majority of subjects had more facial asymmetry such as chin deviation, nasal deviation, and face breadth. Facial asymmetry is typically found in patients undergoing rhinoplasty for a deviated nose, and its presence frequently results in the failure to achieve a straight-looking nose.

Conclusion:

Patients considering rhinoplasty frequently have facial asymmetries, and careful attention should be devoted to these elements in both surgical planning and patient counseling. In order to create facial harmony and apparent symmetry after rhinoplasty, it is critical to center the nose on the midglabellar to mid–bow Cupid’s line.
