The application of laser treatments beginning on the day of stitch removal has been demonstrated to improve scar quality. However, there are few guidelines for the treatment of immature scars (ISs), which are defined as \"scars whose features are not yet expressed.\" The purpose of this study was to extract information about early combination laser treatment (CLT) beyond what is currently known by analyzing 33 pairs of pre-treatment and post-treatment photographs of ISs. Two hundred fifty medical records of patients with scars were reviewed, and 33 scars were included in the study. The included scars were treated with vascular lasers (585 or 532 nm) followed by 1550-nm fractional lasers from May 2014 to July 2015 (fewer than 52 days after stitch removal, Fitzpatrick\'s skin types III-IV, mean age = 16.0 years). Blinded evaluators (one plastic surgeon and two dermatologists) evaluated the pre-treatment and post-treatment photographs. The pre-treatment photographs were scored on a spectrum from \"0,\" when no difference with the surrounding unaffected skin was observed, to \"100,\" when the worst scarring was present. The pre-treatment and post-treatment photographs were compared, and the results were graded on a spectrum from 0, when no difference between the pre-treatment and post-treatment photographs was observed, to 100, when no difference was observed between the post-treatment skin and the surrounding unaffected skin. Statistical analyses were performed with PASW 17.0, SPSS Korea, Seoul, Korea (p < 0.05). The improvement scores (ImS) and weighted scores (Wtd: i.e., weighted according to the pre-treatment scores) were used as dependent variables. The average improvement score was 87.98 (median = 90). Seventeen cases were scored as 100-point improvements. The facial and non-facial scars exhibited differences in the ImS and Wtd scores. The Wtd scores were negatively correlated with the temporal gap (in days) between stitch removal and the beginning of CLT. No significant difference in the Wtd scores was demonstrated between the two vascular laser groups. Patient age and Wtd score were negatively correlated, and a significant difference was observed in the Wtd scores between the age groups (≥15 and <15 years old). CLT for ISs results in excellent outcomes. Better results are achieved with earlier CLT initiation following stitch removal. Better outcomes can be expected for younger patients and for facial scars. We found that 532 and 585-nm lasers are equally effective for CLT of ISs.

Various methods are available for refining scars of the external nose and optimal scar revision frequently requires the utilization of multiple techniques. Differing anatomy of nasal subunits and their underlying structural framework limit surgical options in nasal scar revision compared with other areas of the face. An understanding of a variety of laser technologies and their specific applications can vastly aid in fine, controlled scar revision. Achieving optimal scar reduction regularly requires multiple stages of intervention, close follow-up, and repeat procedures.

Scar formation is an inevitable consequence of wound healing from either a traumatic or a surgical intervention. The aesthetic appearance of a scar is the most important criteria to judge the surgical outcome. An understanding of the anatomy and wound healing along with experience, meticulous planning and technique can reduce complications and improve the surgical outcome. Scar revision does not erase a scar but helps to make it less noticeable and more acceptable. Both surgical and non-surgical techniques, used either alone or in combination can be used for revising a scar. In planning a scar revision surgeon should decide on when to act and the type of technique to use for scar revision to get an aesthetically pleasing outcome. This review article provides overview of methods applied for facial scar revision. This predominantly covers surgical methods.

Most surgical patients end up with a scar and most of these would want at least some improvement in the appearance of the scar. Using sound techniques for wound closure surgeons can, to a certain extent, prevent suboptimal scars. This article reviews the principles of prevention and treatment of suboptimal scars. Surgical techniques of scar revision, i.e., Z plasty, W plasty, and geometrical broken line closure are described. Post-operative care and other adjuvant therapies of scars are described. A short description of dermabrasion and lasers for management of scars is given. It is hoped that this review helps the surgeon to formulate a comprehensive plan for management of scars of these patients.
