AbstractThyroid surgeries are common operations with an extremely low mortality. It is associated with
specific morbidities which are dramatically decreased due to the rapid progression in operative
techniques which helped to make the thyroid surgery less feared and better understood than it
once was. Inferior thyroid artery is one of the vital structures that require special attention during
operative technique in order to avoid troublesome and in most cases a preventable
We conducted this study to assess the: Prevalence and significance of post-operative
hypoparathyroidism following thyroid surgery, with or without inferior thyroid artery ligation.
Incidence of recurrent laryngeal nerve injury with or without inferior thyroid artery ligation.
Intraoperative and post operative bleeding with or without inferior thyroid artery ligation.
A prospective observational study was done from June 2005 to June 2008, at Basrah General
Hospital. One hundred and eight patients underwent subtotal thyroidectomy. Majority of them
(90) patients were females. Patients were placed in two groups, Group I had inferior thyroid
artery ligation whereas in Group II, inferior thyroid artery was not ligated.
Analysis of data reveals that (50%) of patients in group I had hypocalcemia, (16.1%) recurrent
laryngeal nerve injury and (4.83%) hematoma, whereas in group II (47.82%) had hypocalcemia,
(8.7%) recurrent laryngeal nerve injury and (2.17%) hematoma.
Statistically, there is no significant difference regarding post-operative hypocalcaemia,
recurrent laryngeal nerve injury and hematoma formation between truncal ligation and nonligation
of inferior thyroid arteries.~ �C
