RESUMO
Nasolabial folds are caused by loss of deep fat and subsequent loss of muscle contour in the midface, leading to sagging which forms cosmetic issues in some cases when they are otherwise overly pronounced. Various treatment procedures have been developed to reduce their appearance. The objective of this study is to compare the efficacy of hyaluronic acid (HA) cheek fillers injection and thread lifting in improving the nasolabail folds. Twenty cases presenting with prominent nasolabial folds were randomly divided into two groups; group A underwent HA fillers for cheek lifting and group B underwent thread lifting for the cheek. Only one session was done for each case, and then they were followed up after 1 and 2 months. Statistical significant difference after treatment for both groups was detected using the wrinkle severity rating scale (WSRS) and the modified Fitzpatrick wrinkle scale (MFWS). The average global aesthetic improvement scale (GAIS) was 2.2 ± 0.79 for the fillers group and 3.2 ± 0.92 for the threads group, showing a statistical significant improvement with a p value less than 0.05 favoring the fillers group. 70% of fillers cases were satisfied and only 30% of threads cases. Fillers cheek injection is recommended for patients with sagged thin face to improve the nasolabial folds as well as giving volume and contour. Threads would do better for patients desiring an oval, less wide face shape. Combining threads with other cosmetic procedure would give a better holistic appearance.
