Modified Vancouver Scar Scale을 이용한 고전적인 갑상선 절제술 후 수술 흉터의 평가: 단일 기관에서의 283명 환자의 경험

Abstract

Purpose: The postoperative scar of open thyroidectomy is one of the clinical issues in patients diagnosed with thyroid disease. The aim of this study was to analyze postoperative scars in patients who underwent thyroidectomy based on the Modified Vancouver Scar Scale and to find factors for use in predicting formation of hypertrophied scars and keloids. Methods: Clinical data from 283 patients who underwent thyroidectomy were collected randomly and analyzed retrospectively. All postoperative scars were classified according to five categories; excellent, good, moderate, hypertrophied, and keloid, using the Modified Vancouver Scar Scale according to the assessment of pliability, height of the scar, vascularity, and pigmentation. For analysis, hypertrophied and keloid were classified as bad status and others were classified as good status. Results: According to our results, 84.8% of scars were classified as good status and 15.2% of scars were classified as bad status. Forty percent of patients who were in their twenties, 17.8% of patients who were in their thirties, and 22.1% of patients who were in their forties showed bad status; 92.9% of patients who were in their fifties and 89.2% of patients who were in their sixties showed good status (P=0.003). The only statistically significant factor influencing the scar status was the weight of the thyroid (P=0.022). Conclusion: Postoperative scars from thyroid surgery were evaluated using the Modified Vancouver Scar Scale. Age was the most important factor in formation of hypertrophied and keloid scar and the weight of the excised thyroid also influenced the scar status. Preoperative prediction of the status of the scar might be possible considering the age and size of the thyroid gland.
