Surgical management of thyroid diseases--a study on 78 cases.

A total of 78 cases with thyroid diseases were treated surgically in the Department of ENTD, Mymensingh Medical College Hospital during the period from 2000-2001. The different types of surgery were done according to the diagnosis being presented here. Out of 78 cases, 60 (76.9%) were female and 18 (23.1%) were male having female to male ratio of 3.3:1. The highest number, 47 cases (60.3%) belongs to 21-40 year age group. The study revealed the incidence of thyroid diseases as follows: 53 (67.9%) Benign cold single nodular goitre. 17(21.8%) Benign cold multinodular goitre and 08 (10.3%) Papillary carcinoma of thyroid. Regarding surgical management 40 (51.3%) patients underwent hemithyroidectomy. Lobectomy were done for 13 (16.7%), subtotal thyroidectomy for 15 (19.2%), total thyroidectomy for 5 (6.4%) patients and total thyroidectomy with functional neck dissection were performed for 5 (6.4%) patients. The study showed that females were the mostly affected group having benign single cold nodular goitre who were treated surgically by hemithyroidectomy.
