ABSTRACT
INTRODUCTION: Thyroidectomy is one of the most prevalent treatments for thyroid malignancies. It has very low rate of complications except the hypocalcaemia. Only a small number of studies have evaluated the clinical signs of hypocalcaemia but no study have reported the time interval between the procedure and signs of hypocalcaemia. AIM: The aim of this study was to determine that time interval in those patients. MATERIALS AND METHODS: Medical files of a group of patients who underwent thyroidectomy were reviewed. Demographic characteristics of the patients and the time interval to hypocalcaemia were recorded and analysed by SPSS software. p-value <0.05 was considered significant. RESULTS: One hundred and eight patients, 65 women (60.2%) and 43 men (39.8%) with a mean age of 42.6+12.2 years were included. Perioral numbness was reported in 30 (27.8%) patients while 29 (26.8%) patients had lip numbness. Numbness in extremities and muscle spasm were found in 19 (17.6%) and 13 (12%) patients respectively. Seizure was reported in 3 (2.8%) patients. The Trousseau and Chvostek signs were found in 17 (15.7%) and 9 (8.3%) patients respectively. Only the Trousseau sign was different between the two surgical groups. The mean time interval was 41.25±11.5 hours postoperatively. However the time interval was shorter for the total thyroidectomy. CONCLUSION: Physical examination is useful for diagnosing hypocalcaemia due to the presentation of sings during the first 48 hours of thyroidectomy. Total thyroidectomy is associated with shorter time interval.
