Thyroglossal Duct Cyst 101: Ethanol Ablation: Safe Treatment Without Surgery and
- A biopsy was done to confirm the benign nature of the TGD cyst.
- 11 patients with TGDC were treated.
- The initial volume of the cysts ranged from 0.67 to 29.39 mL (mean, 6.0 mL).
- Volume reduction was 43.9%–100% (mean, 81.3%, P = .005) at last follow-up.
- A 41-year-old woman (patient 10). Axial (A) and longitudinal (B) sonograms show the TGDC in a suprahyoid location (2.0 × 2.3 × 3.1 cm; volume, 7.46 mL) filled with fluid. Axial (C) and longitudinal (D) sonograms obtained 13 months after EA show marked shrinkage of the TGDC. (0.35 × 0.6 × 0.76 cm; volume, 1.08 mL; volume reduction, 85.5%)
- A 39-year-old woman (patient 11). Axial (A) and longitudinal (B) sonograms show a multiloculated TGDC in an infrahyoid location (1.2 × 2.0 × 2.2; volume, 2.76 mL). Sagittal CT scan (C) shows that the TGDC wraps around the hyoid bone (arrows). Axial (D) and longitudinal (E) sonograms and a sagittal CT scan (F) obtained 11 months after EA. Arrowheads indicate shrinkage of the TGDC (0.66 × 0.85 × 1.18; volume, 0.35 mL; volume reduction, 87.5%).
- 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.
- PEI seems to be an effective and safe treatment method for TGDC.
