What does thyroid surgery entail?
Thyroid surgery involves partial or total removal of the thyroid gland. The extent of the operation depends on your diagnosis and the reason for the surgery. We will discuss the proposed extent of your operation during your initial office visit.
How should I take my medications prior to surgery?
There are three medication categories which are of concern:
Anticoagulants: If you are on Coumadin or one of the newer anticoagulants such as Pradaxa, or anti platelet drugs such as Plavix, I almost always provide specific advice during the office visit. I often reach a decision in consultation with your cardiologist. If you are at all unclear about what you are supposed to do regarding anticoagulant meds please contact me at least a week prior to surgery.
Aspirin and Ibuprofen (Advil, Motrin) also have anti platelet effects: The rule used to be that you had to stop any of these drugs five days prior to surgery. There is however good evidence to show that low dose Aspirin can be continued. If you take low dose Aspirin as a general preventive measure, you can make your own decision about stopping or continuing. I do advise restricting Ibuprofen for 3-5 days prior to surgery unless you really need to take it.
Medications for hyperthyroidism: (PTU, Methimazole, or Metoprolol) If your surgery is to treat Grave’s disease, or you have an overactive goiter you must NOT stop the medications prior to surgery, and should even take them on the morning of surgery with a sip of water unless anesthesia instructs your otherwise during your preoperative assessment. Following operation you will discontinue all these medications and instead take thyroid hormone. You must have a prescription for thyroid hormone prior to leaving the hospital.
Diabetes medications: During your preoperative assessment you will receive instructions regarding your medications for diabetes.
To be clear, please contact me if you have any questions about any medications prior to surgery.
How can I prepare for my surgery?
Please do not take aspirin or any anti-inflammatory drugs including Advil or Motrin for at least five days prior to surgery. These drugs can interfere with platelet function, and may increase bleeding. If you accidentally take one of these drugs within five days of surgery, please let me know. If you have had a stent placed in your coronary arteries within the past 12 months, it may not be safe to stop your aspirin regimen, and we will need to discuss this with your cardiologist. Tylenol does not interfere with platelet function and is safe to take for headaches or minor pains before surgery.
Because general anesthesia will be administered for the operation, you will require an evaluation a few days before your surgery. Depending on your age and general health, this evaluation may be conducted by telephone, or you may need to be seen in the preoperative testing unit at the hospital. This decision will be made at the time we set up your operation. If you need to be seen, you will be given an appointment, time, and directions for the preoperative visit. Whether the evaluation takes place over the phone or in person, you will be asked many of the same questions that I asked in our first visit, particularly about medications and any past anesthetic history. During the preoperative evaluation, you will be told when to stop eating and drinking, and what medications to take prior to surgery. Please be sure that you understand these instructions and follow them. Otherwise, your surgery could be cancelled.
Please call your endocrinologist to let them know the date of your surgery and ask them when you should be seen for a postoperative visit.
How do I confirm the time of my surgery?
Make sure that we have a number to call in case the time of operation is changed with late notice. Call my office on the day before your surgery to confirm the time and place. If your operation is scheduled for a Monday, call the office on the preceding Friday between 9 am and 2 pm to confirm the time. Should you develop a cold, sore throat, fever, or other symptoms of a viral illness in the days before the scheduled operation, be sure to let the office know so that we can decide on the best course of action.

What can I expect when I arrive at the hospital?
You will first register at the reception desk, so that the staff is aware of your arrival before you proceed to the waiting area. After a brief wait, you will be taken to the preoperative holding area where you will be made ready for surgery. You will see nurses, anesthesiologists, my surgical residents, and me. You will be asked to sign the consent forms for surgery and anesthesia. I will mark your neck in an optimal place, so that once healed, the scar will be barely noticeable. When all of the necessary checks have been made, we will take you into the operating room. You will have received some sedation and you may not remember being moved. The team will help position you on the table, and then the anesthesiologist will gently send you off to sleep.
Who will perform my surgery?
I will perform your thyroid surgery with the help of an assistant, who is normally a surgical resident. In some cases, there will also be a medical student present in order to observe. While I am teaching the resident, I am primarily focused on conducting your surgery. In fact, when training residents, I must make sure that the surgery I perform is top notch. I am in total control of every step of your operation – have no concern.
Will I need a blood transfusion?
Patients sometimes wonder about the need for blood transfusion. You will lose minimal blood during surgery. Unless there is a special situation that I would have discussed with you beforehand, you can assume you will not need a blood transfusion. One of the risks of any surgery is postoperative bleeding. This is very rare. If bleeding is significant, you will need to go back to the operating room. This is very rare (less than 1%) and even in this case, we rarely need to give a blood transfusion.
What will happen during my surgery?
I will begin the operation by cleaning the skin with antiseptic, and then arranging towels around the area. I will use the pen mark placed on the prep area as a guide, and will open the skin to expose the underlying thyroid gland. After gaining exposure, I will inspect the area and decide on the best approach. I always remove the entire thyroid lobe rather than simply removing the tumor, because doing so is the safer approach with the best outlook for your health. When removing the lobe, I take great care to avoid injury to the laryngeal nerves and the parathyroid glands.
The laryngeal nerves, which control the quality of your voice, are sometimes closely involved with the lump on your gland, and these nerves may become stretched during the operation. Your voice may sound a bit abnormal for a few days, weeks, or, in rare cases, months. You may sound slightly hoarse, or you may be unable to shout or sing high notes. You will, however, be able to make yourself understood without difficulty. The nerves are very sensitive and sometimes even trivial stretching will affect them. I use a nerve monitor to help protect your nerves, but despite every precaution, vocal change is one of the risks of thyroid surgery. Fortunately, permanent change is very unusual (less than 1%). Rarely, the nerves may have been invaded by the tumor on your thyroid gland, in which case the nerves must be removed in order to ensure complete removal of the tumor. The outlook for patients’ voices is often positive in this rare case, but additional treatments to improve the voice are available if necessary.
There are two parathyroid glands on each side of the neck. I look for them very carefully, and gently separate them from the thyroid gland when removing the thyroid lobe. They are very delicate, and their function may be impacted for several days. This is only a concern if both thyroid lobes are removed. In the case of a single sided operation, the untouched parathyroid glands on the other side are more than capable of taking over until the glands on the operated side recover. When I perform a total thyroidectomy, all four parathyroid glands are at risk. If they are affected, a patient’s blood calcium level may drop for a few days following surgery, and in some cases for longer, or even permanently. Often, no treatment is necessary, but some patients require calcium or vitamin D supplements for a few weeks, months, and, rarely, permanently. In some cases, we reimplant a parathyroid gland into a muscle pocket. The transplanted parathyroid regains function after a few weeks, thus avoiding any permanent issues with calcium levels in the blood.
The operation time is dependent on how much of the thyroid I remove, and the type of disease. A rough estimate would be two hours, including the time taken for anesthesia.
Once I have removed the gland, it is sent to pathology. I will call you with the results approximately one week after surgery.
The final cosmetic result is very important. I plan the incision with this in mind, and close the skin as neatly as possible. I will not make the incision any longer than necessary to perform the resection safely and properly. I close the skin with sutures under the skin, and then apply steristrips or skin glue to cover the actual wound.
If there is a family member you would like me to call following surgery, please ensure that I have a phone number at which they will be easily available. They will not be able to see you for a couple of hours after the surgery.
What can I expect during recovery?
Once you have awoken from the anesthetic, you will be taken to the recovery room, and observed for an hour or two until you are fully awake. You will not have any tubes down your throat or drains in your wound. You will only have an IV in your arm. I will see you in the recovery room and will tell you how your procedure went, but you are unlikely to remember this because anesthetic drugs impair memory. I will call or speak with your family or friends as soon as the operation is over. They will be able to see you a couple of hours after surgery.
Patients often ask how much pain to expect. While the response seems variable, most patients do not report a great deal of pain. In any case, I will give you a supply of pain medication.
Most patients can go home within 4-6 hours after their thyroid surgery. I will delay your discharge if you live alone, or a great distance from the hospital. In addition, if the operation has taken longer than I expected, or starts late in the day, I may admit you to the hospital overnight. In some cases, the lingering effects of anesthesia can cause nausea, and discharge will be delayed.
If you have one lobe removed, you may not need a prescription for synthetic thyroid hormone, but if you have a total thyroidectomy you do need a prescription and must not leave the hospital without it. The final dose of hormone will be determined about a month after surgery when you see me, or your endocrinologist. The dose of thyroid hormone initially prescribed is determined by a body weight formula and is almost always very close to what you need. No side effects will result from this dose of thyroid hormone. You will not gain or lose excess weight.
At the time of discharge, you will be given a prescription for pain medication. All pain medication has a constipating effect. You may be able to avoid this by using a stool softener such as Colace or Metamucil. These are over-the-counter preparations, and you can use them in the event that you become constipated. They must be taken with a large amount of water.
As mentioned above, in the event of a total thyroidectomy, you may experience a drop in your blood calcium level. As a symptom, you may feel tingling around your lips or in your arms and legs. If this tingling is mild, you can take TUMS (2 tabs four times per day for a few days until the tingling stops). If you develop leg cramps or you find it hard to bend and straighten your fingers, or if the tingling does not improve or increases, then your blood calcium is continuing to decrease. In this case, please call me. If you cannot reach me, go to BIDMC or to your local emergency room. You will require intravenous calcium and oral medication. You will recover completely with time.
How do I care for my wound?
You can shower and expose the wound to water within a day of your surgery. Soaking the incision in a tub is probably best delayed for about a week, unless I have closed your skin with waterproof skin glue. When you get out of the shower, pat the area dry because wiping will tend to remove the steristrips. There is no need to cover the steristrips and they will generally stay on for a week to 10 days, but this is variable. You can trim the ends with scissors as they begin to peel off, and then remove them entirely after 7-10 days if they are still in place. Sometimes, neck incisions swell after a few days. This is normal and will go down within a few weeks. It is also normal for the skin above and below the incision to be numb. This can last for several months.
In order to reduce discoloration of the scar it is a good idea to apply an ultraviolet barrier cream (SPF 20) to the scar when you are exposed to sunshine, for two years following operation. Vitamin E is thought to help minimize scarring and my plastic surgery colleagues are keen on Scaraway, a silicone preparation available at CVS or online. Maderma is another preparation you can use to treat the incision. I have no preference. Any of these preparations can be used once the steristrips are off.
How should I change my diet?
There is no need for any special diet, but in the days after your operation you may find soft foods easier to swallow.
How much energy will I have after surgery? Post-operative fatigue is a concern for some patients. For lack of a better term, I call it the “post-operative poop-out syndrome”. Patients notice a particular lack of energy, mostly in the afternoon, for up to six weeks following operation. This is normal for some patients, and should resolve completely by six weeks.
Can I remain active after my surgery?
I suggest a common sense approach to activity following thyroid surgery. You can return to work as soon as you are comfortable enough. If, for example, you have a sedentary job, you may wish to go back after a week. I would avoid contact sports, or activities such as skiing, until a fall will be unlikely to impair healing (three to four weeks). You can swim as soon as the skin has healed (5-7 days).You can drive a car as soon as you are comfortable and not taking pain medications, but remember that residual neck discomfort may prevent you from turning your head quickly. Therefore, please do not drive until you can turn you head normally. In order to reduce discoloration of the scar it is a good idea to apply an ultraviolet barrier cream (SPF 20) to the scar when you are exposed to sunshine, for two years following operation. Vitamin E is thought to help minimize scarring and my plastic surgery colleagues are keen on Scaraway, a silicone preparation available at CVS or online.
What should I do if I experience concerns immediately following surgery?
You will always have access to medical professionals in the event that you experience a problem upon arriving home from your surgery. Problems that may concern you are excess swelling, redness, and tingling that won’t go away. Be ready to take a picture of your incision if there is a concern. It’s often helpful for me to see how it looks and can save you a trip to the hospital or my office. If you have trouble reaching me, please visit the emergency room. A resident from my team is always on call.
What can I expect from my post-operative visit?
I generally see patients in the office for a post-operative visit at about four weeks following surgery. Please call and make an appointment. I do not need to see you earlier unless one of my residents or I asks you to make an earlier appointment. Additionally, please call your endocrinologist’s office and make an appointment before or after you have seen me, depending on their preference.
If you live a long way from my office and you have recovered well, and have no questions or concerns, you may not feel inclined to travel all the way in to have me look at the wound. In that case please just call my office and tell the staff you have no particular need for a postoperative visit and can do this on the phone. Whatever suits you best is fine with me.
If you have not heard from me about the pathology results within seven working days of surgery, please call the office.
Finally, if you have any questions prior to surgery, write them down before you forget them, and call the office, or preferably email me directly.
