Multinodular goiter is a common disorder of the thyroid gland, whenever surgery is indicated for a simple multinodular goiter; the current trend usually is to do total thyroidectomy that leads the patient to take a lifelong hormone replacement therapy, a daily dependence on it and regular visits to hospital to check hormone levels are burdensome. Other problems that may interfere with reaching a euthyroid status using replacement therapy are malabsorption and noncompliance of patients Thyroid autotransplantation is to leave thyroid tissue in the body that might be able to avoid or reduce severity of post-thyroidectomy hypothyroidism in noncompliant patients and if recurrence occurs it would not be in the neck, thus avoiding compression on the trachea and avoiding dangerous reoperation in the neck In this study we are trying to assess survival and function of autotransplanted thyroid tissue after total thyroidectomy in patients with multinodular goiter, and relation between amount of grafted thyroid tissue and duration after which patient get euthyroid status, as alternative method to avoid replacement therapy.
