Rhinoplasty Following Nasal Trauma

Probably the most frequently traumatised area is at the rhinion where the skin is thinnest. Lacerations should be cleaned, dressed or sutured primarily to prevent tattooing. Adequate sun protection of scars, moisturising, massaging and use of silicone gel daily all contribute to good cosmetic scar result.
Microneedling in Clinical Practice

Several studies have demonstrated the beneficial effects of microneedling on acne scars (37). Rolling and boxcar scars respond well to microneedling treatment as opposed to deep or icepick scars, with a corresponding increase in types I, III, VII, and newly synthesized collagen as well as tropoelastin (38). Fractional radiofrequency microneedling, on the other hand, has been shown to improve icepick acne scars (39). Hypertrophic scars and keloids have shown improvement in combination therapy with silicone gel (40). Silicone gel is thought to improve scars by increasing hydration of the stratum corneum, with subsequent cytokine-mediated signaling from keratinocytes to dermal fibroblasts to downregulate extracellular matrix production (41). Microneedling's synergistic action of collagen remodeling likely accounts for the improvement seen in this combination.
Wound care

There are various formulations of silicone gel. Clear gel sheeting (Cica Care®) may be more effective than liquid gel (Dermatix Ultra®) for reducing scar height, itch and erythema; however, compliance is much improved when using the latter, making the overall effect similar.

There are numerous surgical therapeutic modalities aimed at skin repigmentation in stable vitiligo (1). Minipunch grafting remains a simple, relatively quick, cheap and easy technique which can be done by any dermatologist who is skilled at obtaining punch biopsies (2). Cobblestoning is the most common complication of minipunch grafting (3). It is a morphological diagnosis denoting a raised skin surface, resembling cobblestones (4). Komen et al. (5) found that 1.5 mm grafts produced more absolute pigment spread while 1 mm punches produce less risk of cobblestone formation. A comprehensive scoring system (6) was used in this work to assess the outcome of surgical therapy in vitiligo regarding the extent of pigmentation, color match, and complications, including cobblestoning. Silicone gel usage post operatively has a role in the induction of perfect wound healing (7).

The therapeutic effect of silicone gel sheet application on hypertrophic and keloid scars was reported by several studies (Perkins et al. 1983; Li-Tsang et al. 2006; Maján 2006). Gold et al. (2001) performed a randomised controlled trial (RCT) in a high-risk group of patients with a history of hypertrophic or keloid scars and indicated that the application of silicone materials could even prevent excessive scar formation. In this RCT, the scars occurred at various locations such as the back, arms, abdomen and the breast. Other studies have also shown a prophylactic effect of the application of silicone materials against the development of hypertrophic and keloid scars (Cruz-Korchin 1996; Tosa et al. 2013). Several treatment options have been developed for abnormal scar formation after operation, such as pressure therapy, paper tapes, silicone materials, corticosteroid injection and surgery (Atkinson et al. 2005; Rabello et al. 2014; Lee and Jang 2018). Among them, silicone gel sheet is considered one of the first-line therapy for the prevention of abnormal scar formation (Bleasdale et al. 2015; Ogawa et al. 2019). However, some limitations of the silicone sheet, such as its high cost and the fact that it can be easily peeled off, are also known (Kim et al. 2014).
Breast implant causes allergic contact dermatitis or foreign body reaction?

Previous research showed that silicone is a chemically stable compound but also, that they are capable of inducing an antigen-specific lymphocyte-medicated response to the silicone gel like a type IV hypersensitivity reaction [7,9]. When a patient has had a prior history of reactions to adhesives the possibility of a type IV hypersensitivity reaction to a silicone implant increases. Histologically lymphoid cells and granuloma are present on the implant capsule. In our patient the histology of the removed capsule with expander showed granulation tissue, fibrosis and an infiltrate consisting of lymphocytes, plasma cells, eosinophil en neutrophil granulocytes. This reaction can be seen as a reactive inflammatory process to the foreign-body. Since the histological findings were not specific and our patient did not had a prior history of reactions to adhesives, the type IV reaction seems to be unlikely.
