ABSTRACT
Background: Despite various complication rates of thyroidectomy having been reported, there is still nocommon consensus on the surgical procedure around the world.Aim: In this study, we aimed to evaluate the rate of complications after thyroid surgery and the riskfactors contributing to the complications.Methods: In this retrospective study, 1159 consecutive patients operated between 1995 and 2005 wereevaluated. Patients follow up data were obtained from hospital records, telephone interviews with patientsand additional information was retrieved from our clinic’s database. The patients with missing data wereexcluded. Gender, physical findings, imaging methods, laboratory results, extent of resection, differencesin the surgical technique, history of previous thyroid surgery, perioperative complications andhistopathologic diagnosis were interrogated as factors affecting the post-operative complications such ashypocalcemia and recurrent laryngeal nevre palsy. Statistical analysis (χ² or the Fisher's exact test,Student's t-test or the Mann-Whitney U tests) was performed using the SPSS (Statistical Package forSocial Sciences, Chicago, USA) program.Results: The mean age of patients was 43.3 (7-78) years. In the early postoperative period, the mostfrequently seen complications were vocal cord paralysis (n=146, 12.6%) and hypocalcemia(n=131,11.3%). In our study, permanent vocal cord paralysis occurred in 39 (3.4%) patients. The rate ofpermanent recurrent laryngeal nevre palsy was 1.9% when assessed per nerve at risk. The risk factorsaffecting recurrent larngeal nevre palsy were adhesions (p=0.05), recurrent thyroidectomy operation (p
