Background:A chin that is of right size, shape, and contour plays a crucial role in overall facial balance and esthetically harmonious appearance. Dermal fillers have been widely used for correcting mild to moderate chin retrusion and resorption. Aims:The aim of this study was to share our preferential technique for chin augmentation and to evaluate our results in 50 patients. Methods:A total of 50 patients consisting of females who received hyaluronic acid injection for chin augmentation and rejuvenation were enrolled in the study. We have described chin augmentation technique with the use of cannula from a single, midline entry point. Results:The study included 50 female patients, and the mean age was 37.56 ± 8.84 years. The median injected filler volume for augmentation of the mental area was 2.25 mL (minimum = 1, maximum = 4 mL). Four (8%) patients had ecchymosis related to the procedure. Conclusion:Chin has a profound effect on the perception of attractiveness and is an area of concern for rejuvenation of the lower third of the face. Our preferential technique allows the practitioners to increase the likelihood of a satisfactory esthetic outcomes and minimize the risks of the procedure.

Narrowband ultraviolet B (NB-UVB) phototherapy (311 nm) has become a widely used, standard treatment modality in dermatology since it was first introduced in the Netherlands in the early 1980s. 1-3 It is highly effective for the treatment of psoriasis, vitiligo, atopic dermatitis, lichen planus, and many other inflammatory skin diseases. 4,5

Rosacea is a chronic inflammatory skin disease that is characterized by recurrent episodes of erythema, telangiectasia and papulopustular lesions. Although the pathogenesis is not well established, growing knowledge suggests that multiple etiological factors play a role resulting in inflammation. The aim of the present study is to investigate inflammatory status of patients with rosacea by evaluating CBC parameters and systemic immune inflammation (SII) index and compare these parameters with control group. Thus, it is aimed to understand the role of systemic inflammation in the pathogenesis of the disease. This retrospective, case–control study included 100 patients with rosacea and 58 sex- and age-matched controls. Laboratory examinations including CBC, ESR, CRP, HDL, LDL, and triglyceride levels were recorded and neutrophil–lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR), monocyte-to-high-density lipoprotein ratio (MHR) and SII index were calculated. Monocyte and platelet count, SII index, ESR and CRP were significantly higher in patients with rosacea than in the control group. No statistically significant difference was found in other parameters. There was no significant correlation between disease severity and ESR, CRP, and SII index. The findings of this study suggest that apart from the inflammatory pathways at the level of skin, there is an inflammatory state in the blood of patients. Rosacea is a skin disease, but it may have systemic implications and/or associations that need to be clarified completely.
