Hi, I understand your concern about your child. Before proceeding for Thyroglossal cyst surgery, you need to confirm the position and function of normal thyroid tissues. It is not an emergency surgery unless it get infected. Age of surgery varies with individual children. Other than surgery, sclerotherapy (injecting medicine into the cyst) can be done. I would advise you to get pediatric surgeon opinion for further management and follow up. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Nirubhan Bharathy, Pediatrician
