Abstract
TGDC is a common congenital neck lesion, which has been treated by surgery. Although surgery is curative, it has drawbacks such as scars and surgical morbidity. Therefore, we applied EA as an alternative treatment technique. The purpose of this study was the evaluation of the efficacy and safety of EA for TGDC. Between May 2005 and July 2008, we performed EA in 11 patients with TGDC who refused surgery. All patients were confirmed as having benign lesions before treatment. US-guided aspiration of the cystic fluid was followed by injection of absolute ethanol (99%). The injected volume of ethanol was 50%-80% of the volume of fluid aspirated. We evaluated the therapeutic outcome, including volume reduction of the TGDC, improvement of cosmetic problems and symptoms, and complications. The initial volume of the cysts ranged from 0.67 to 29.39 mL (mean, 6.0 mL). The procedure was performed in 1-3 sessions (mean, 1.4 sessions). Follow-up US was performed in 10 patients from 3 to 29 months (mean, 13.6 months). The mean volume of the cyst was 6.0 ± 8.4 mL, and volume reduction was 43.9%-100% (mean, 81.3%, P = .005) at last follow-up. Therapeutic success (volume reduction of >50%) was observed in 8 patients (8/10, 80%). Significant improvement of symptom- (P = .005) and cosmetic-grading scores (P = .003) was observed at last follow-up. No significant complications were observed during the procedure or follow-up periods. EA seems to be an effective and safe treatment method for TGDC.
Highlights
AND PURPOSE: TGDC is a common congenital neck lesion, which has been treated by surgery
The recurrence rate could be reduced to 2.6%–5% by the Sistrunk procedure[2,4,7]; surgery still has some drawbacks such as the use of general anesthesia, scars, and surgical morbidity.[1,2,4,5,6,7]
Eleven of these patients were enrolled because they fulfilled the following criteria: cosmetic concerns and/or symptomatic problems such as pain, swelling, discomfort, or dysphasia; a single clinically palpable midline mass in the anterior aspect of the neck that was diagnosed as a benign lesion; a cystic component of Ͼ90% of the total nodule volume; refusal of surgery; TGDC recurring after aspiration of the internal content in at least 2 separated sessions; and follow-up for Ͼ3 months
