Scars and satisfaction: do smaller scars improve patient-reported outcome?

Thyroidectomy has few complications, as a result, many patients are concerned about the prominence of their scar. Performing thyroid surgery through excessively small incisions in order to maximise cosmesis may increase the likelihood of complications. This study investigates the relationship between conventional approach thyroidectomy scar length and patient satisfaction. A validation of self-measurement of neck circumference and thyroidectomy scar was carried out with the measurements taken by patients compared with those taken by an investigator. One hundred consecutive patients who had undergone conventional thyroidectomy and total thyroidectomy within 24 months were invited to measure their scars and neck circumference, and to score their satisfaction on a Likert scale of 1–10. Spearman’s correlation was calculated for the relationship between absolute and relative scar length, and patient satisfaction. Thirty-four patients entered the preliminary study and 80 patients entered the main study (80% response rate). Measurements by patients and investigators were closely associated: Spearman’s Rank correlation coeYcient for neck circumference and for scar length were  = 0.9, p < 0.0001 and  = 0.93, p < 0.0001 respectively. No signiWcant correlation was evident between scar length and patient satisfaction ( = 0.068, p = 0.55), or between relative scar length ratio and patient satisfaction ( = ،0.045, p = 0.69). Mean scar length was 6.96 cm [standard deviation (SD) 2.70], and mean satisfaction score 8.62 (SD 2.04). Thyroidectomy scar length appears to have no association with patient satisfaction. Thyroid surgery should, therefore, not be performed through unnecessarily small incisions for purely aesthetic reasons
