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