Thyroid nodule surgery usually requires a hospital stay of about 3 to 7 days, but because each thyroid nodule patient’s condition is different, the length of time a patient needs to stay in the hospital may not be exactly the same, and it is recommended that you consult your doctor. How many days you need to stay in the hospital for thyroid nodule surgery depends on your condition, the type of surgery, and other factors. With radiofrequency ablation, recovery is quicker after the procedure, so a hospital stay of 3 to 4 days is usually sufficient; in the case of open surgery, a hospital stay of about a week may be required. If bleeding, hematoma, or infection occurs after the procedure, a longer hospital stay will be required. Patients diagnosed with thyroid nodules should actively cooperate with doctors for treatment.
