Abstract

Background: The heterotropic thyroid autotransolantation is to leave thyroid tissue in the body that might be able survive, gain blood supply and become functioning to avoid or reduce the severity of post thyroidectomy hypothyroidism in noncompliant patients. In the meantime, if recurrence occurs it would not be in the neck, thus avoiding the compression of the trachea and avoid dangerous re-operation deeply in the neck
Methods: Form 1/11/2017 till 1/7/2018. Patients with benign thyroid disorders were selected for heterotropic thyroid autotransolantation followed up for 12 months by duplex us , free T3, T4 , TSH and 99mTc to detect survival of the graft maintaining the patient euthyroid after total thyroidectomy for benign thyroid disorders.
Results: ninety percent were males and 40 % females with mean age 36.2 years. The most common presentation was compressive symptoms (51.6%). Mean operative time was 124.4 min, 71% were benign follicular lesion and 29% colloid nodular goitre , 71% without early postoperative complications. Transient hypocalcaemia reported in 29% 0f cases .one month postoperative duplex was positive in 93.5%. Postoperative radio-isotopic scanning was positive in 93.1% after 6 months and 96.5% after 12 months.90% of the patient reached euthyroid state.
Conclusions: Autotransplantation of heterotrophic thyroid tissue following total thyroidectomy for patients with benign thyroid disorders is a safe , easy and applicable technique that provides survival and function of thyroid graft achieving a postoperative euthyroid state in majority of selected patients without the need for further replacement therapy.
