Successful treatment of thyroidectomy scar with a pneumatic needleless injector and silicone gel

Dear Editors, Thyroidectomy is the most frequently used method when performing surgery for thyroid cancer. A transverse incision on the neck is typically used to approach the thyroid; scar formation in highly visible areas of the neck is a consequence of using this method. The mean score of the Dermatology Life Quality Index for persons who have a thyroidectomy scar is similar to the mean score of patients with psoriasis and severe atopic dermatitis (1). In this study, we report the effects of a pneumatic needleless injector and silicone gel on scar remodelling in the case of a male patient with a thyroidectomy scar. A 41-year-old male patient visited our hospital to lessen the conspicuousness of a thyroidectomy scar (Figure 1). He underwent a total thyroidectomy and bilateral central node dissection 2 weeks prior to his visit. He had an erythematous protruding scar, with a length of 6 cm and a thickness of 3 mm. The Vancouver Scar Scale (VSS), including pigmentation, vascularity, pliability and height, was used for clinical assessment. The first time the patient presented, his VSS score was 7 points. We had him apply a silicone gel sheet (Scar-ClinicTM; Hans Biomed / Ildong Pharmaceutical Co, Ltd, Seoul, Korea) to only the left side of
