Thyroglossal duct cysts are the most common forms of congeLital neck swelling .They are liable for infection &also for malignant transformation .Incorrect management of the infected cyst may end with formation of thyroglssal fistula. Sistrunk’s operation is still the procedure of choice in spite of its recurrence rate about4 %.In this series 32patients underwent the conventional Sistrnk’s operation with moderate modification represented by electocoagulation of the dissected plane of tissues. Twenty eight patients (88%) of the total series were presented with asymptomatic naci swelling; 6%with inflamed neck swelling; 6%with TGD fistula; they were scheduled to undergo the above surgical operation over a period of 4.5years .average age was9.125year; male: female ratiowas1.8:1 Recurrence rate was0%; the mean follow up period was 18 month, 6%of them presented with post operative complications. Electrocoagulation of the dissected plane of tissue in Sistrunk’s probably offer more warranty for ablation of ductuli & thence minimize the recurrence rate.
