We studied the rationale of individual choice in our population Materials and methods: A questionnaire with 7 questions. Was administered to three groups of healthy volunteers. Group 1 (N=30, public); group 2(N=30, nursing staff) and group 3 (N=30), doctors) the individuals were asked to answer the questions assuming that they had a 1-4cm DTC Results: 90 individuals were enrolled. Hemithyroidectomy was preferred in 16 subjects (17.8%) most were women (N=14, 87.5%) and commonest reason being to avoid drug supplementation. (N=10,62.5%). In this group, 7 patients (43.8%) were concerned with completion thyroidectomy. Total thyroidectomy was preferred in 29 patients (32.2%) commonest reason being avoidance of serial ultrasound follow up (N=21, 72.4 %). Majority of respondents were undecided N=45(50%). and had concerns about hormone replacement (N=30, 66.6%) and regarding resurgery and its complications (N=28, 62.2%). Conclusion: Majority of individuals do not have a preference for the extent of surgery. Patients who preferred hemithyroidectomy were concerned about the completion thyroidectomy if required. The difficulties of follow up were the reasons for election of total thyroidectomy in most individuals. Institutional and regional data regarding complications, completion thyroidectomy and risk stratified follow up will help to counsel the undecided patient References:
