Аннотация
BACKGROUND: Alar base is the basal part where the two sides of the nose and the upper lip are connected. Alar base depression affects the overall facial contour by making the nasolabial folds deepen, the nasolabial angle smaller, the center of the face flat, etc. Despite the rapid development of rhinoplasty, controversy still exists regarding the treatment of alar base depression. This systematic review aims to evaluate the efficacy and safety of two prevalent techniques-diced autologous cartilage and mass cartilage-for addressing alar base depression.
METHODS: A systematic review was conducted by searching the literature published in PubMed, Embase and Web of Science, Cochrane from January 2000 to April 2023 with the key words 'alar base depression or depressed alar base' and 'alar base augmentation,' and 2 investigators independently screened the retrieved literature according to inclusion and exclusion criteria.
RESULTS: A total of 269 articles were obtained through database search. After removing duplicates, reading titles and abstracts, and finally reviewing the full text, 6 articles were included in the final study, including 165 patients.
CONCLUSIONS: The results demonstrate that both diced autologous cartilage and mass cartilage techniques exhibit favorable outcomes in correcting alar base depression. Diced autologous cartilage offers better malleability, lighter border contours, and a more natural appearance. On the other hand, diced autologous cartilage seems to offer superior long-term effects, while mass cartilage presents certain surgical procedural advantages. Also, compared to diced cartilage, mass cartilage may have a lower rate of long-term resorption and a lower risk of displacement. This review emphasizes the need for personalized treatment selection based on individual patient characteristics.
LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors. www.springer.com/00266 .
