Introduction: Thyroid lobectomy has the advantage of sparing many patients from the need of thyroxine definitive replacement therapy.
Objective: To evaluate the thyroid function after the hemithyroidectomy and the risk factors for the postoperative hypothyroidism.Methods: It is a retrospective study of 333 consecutive patients undergone thyroid lobectomy and isthmusectomy from 2007 to 2014. Thyroid hormone determinations were performed before and one month after the surgical approach and were correlated to demographic, clinical e histopathological data. The Mann-Whitney U Test and the Exact Test of Fischer were employed.Results: The mass of the remaining lobe presented some statistical trend (p=0.0949) as risk factor for the hypothyroidism. No statistical significance was observed regarding the other analyzed aspects.Conclusion: Subclinical hypothyroidism was detected in 26.1%, whereas clinical hypothyroidism was detected in 3% of the patients in the postoperative period. The mass of the preserved lobe presented some statistical trend (p=0.0949) as risk factor for the hypothyroidism.
