This was a study cross sectional prospective study. This study was done in the Department of otolaryngology and Head Neck Surgery, Rajshahi Medical College Hospital. Rajshshi, Bangladesh during the period from 2015 January to 2015 December. Our aim was to identify risk factors of Hypothyroidism in adult patients. All patients were evaluated for age, sex, pre-operative and post-operative TSH levels, histopathology and follow up. Time of diagnosis and therapeutic dose of thyroid hormone were determined for patients with hypothyroidism. Out of 50 patients 11(22%) patients had become hypothyroid after surgery (9 females and 2 males). Female & male ratio is 5.25:1. The remaining 39 patients (33 females & 6 males) were euthyroid. The mean preoperative serum thyroid stimulating hormone (TSH) levels in hypothyroid and euthyroid groups were 3.14µIU/L & 2.008 µIU/L respectively. A tissue diagnosis consistent with multi-nodular goitre (27%), lymphocytic infiltration or hashimoto thyroiditis (18%) compared with euthyroid patients (30% & 2%).Approximately 15-30% of patients who undergo hemithyroidectomy may have this complication, and some may need thyroid hormone replacement therapy. Patients at increased risk for postoperative hypothyroidism should be made aware of their risk factors and undergo more intensive follow-up. Maximum incidence of hypothyroidism following hemithyroidectomy in 3rd and 4th decade. Compared with those who were euthyroid, there was no significance difference in age, family history of goiter.
