Objective. To compare the quality of resulting scar at 6 weeks after total thyroidectomy with the use of the tissue adhesive octyl-cyanoacrylate or subcuticular absorbable suture for the closure of cervicotomy. Material and Methods. There are 50 patients undergoing a cervicotomy for total thyroidectomy. Twenty-five patients were randomly assigned to closure with tissue adhesive and 25 with subcuticular absorbable suture. At week 6 the scar was evaluated by blinded assessors with the Italian version of POSAS questionnaire, a validated wound scale composed of an observer’s and a patient’s subscale. Results. Assessment of scar appearance showed a statistically significant difference ( ) in favor of subcuticular suture with respect to tissue adhesive on observer’s assessment. The difference on patients’ self-assessment was not significant. A multivariate analysis of six qualitative features of scars showed a significant influence on assessment for hyperpigmentation and relief of scar. The Italian version of POSAS proved to be reliable. Conclusion. Though tissue adhesive represents a valid method of skin closure, subcuticular absorbable suture provides a better aesthetic outcome in small cervical incisions in the early phase after thyroid surgery. 1. Background Aesthetic outcome is particularly relevant in thyroid surgery since patients are mostly women and young adults and since the incision is in a highly sensitive and visible anatomic location. Cosmetic concern about the final scar appearance contributed to motivate the development of minimally invasive approaches for thyroid surgery and parathyroid surgery over the last decade [1–3]. Minimally invasive thyroid surgery techniques (MIT) are different but all share the same goals: reduction of tissue trauma, early hospital discharge, and better neck wound cosmetic appearance, while maintaining the same surgical outcome as traditional thyroidectomy [4]. In addition to MIT, methods of skin closure contribute to the overall aesthetic outcome and patient’s satisfaction. Methods of skin closure vary in published series and are largely the results of surgeon’s choice based upon the need for a rapid, economic, and reproducible technique [5]. Skin closure techniques include the use of the tissue adhesive octyl-cyanoacrylate, introduced 15 years ago in clinical practice as an ideal system of wound closure [6]. Many studies showed that tissue adhesive is an acceptable alternative to standard wound closure since it yields similar clinical and aesthetic results, even if early wound dehiscence occurs in the 1% to 5% of
