You can usually shower about 15 days after thyroid surgery. Thyroid surgery makes a curved incision in the lower part of the front of the neck, and the sutures can be removed about 5-6 days after the surgery. However, the wound is not completely healed at this time, so if bathing can lead to redness, swelling, bacterial infection, or even cracking, it is best to bathe after 1 week, so the time should be about 15 days after the surgery. If the patient has complications after surgery, such as bleeding in the neck, lymphatic fistula, etc., and needs to prolong the time of drain placement, then the bathing time may have to be extended a little later, until the neck drain is removed and the drainage port is completely healed, and then wait for another week or so before you can bathe.
