Tonsillectomy and adenoidectomy


     In followup to our last post, today we are going to talk about tonsillectomy and adenoidectomy.  As we discussed, the indications for this procedure have changed greatly over the last 20+ years.  Formerly, it was a procedure done for infections and now it is much more frequently done for obstructive sleep apnea.  Whatever the indication for surgery, the procedure really is the same. 
     For children, the day before surgery your doctor will generally want them to have nothing to eat or drink after midnight.  This can be variable from center to center so be sure to discuss this with your doctor at your appointment.  It truly depends on the time of day your child will be going to surgery.  Once at the surgery site, your child will be checked in and routinely will go to a preoperative holding area ("PREOP").  There, your child will get a gown, get their vitals taken, meet the operating room team, see your doctor as well as meet and talk with the anesthesiologist.  This is a great time for any last minute questions that have come up since your last appointment.

     Depending on the child and the medical condition, your child may receive some relaxing medicine in the preop area.  Then, it is off to the operating room.  The anesthesia team will put your child to sleep and then the surgery begins.  The surgery time, from the time the patient leaves your side to the time the doctor comes to talk to you is about 30-45 minutes.  Afterwards, the anesthesiologists begin the wake-up process and the children come to the recovery room.  Once safe and awake, you will be called back to be with your child.  Some children will be required to stay overnight in the hospital for observation.  This will be at the discretion of your surgeon.  Usually, most children are able to be discharged the morning after surgery if required to stay. 
     The first 5-7 days are usually the most difficult in the recovery.  Then the children are starting to feel a bit better.  They should maintain a soft diet for 2 weeks after surgery.  This means nothing crunchy to eat.  No chips, crackers, cookies, crusty breads, or pizza crust.  Popsicles, ice cream, macaroni and cheese, mashed potatoes, and things like these are good things with which to start.  We also ask that you keep the child's activity under control for the first 2 weeks after surgery.  This can be difficult, which we understand, particularly during that second week.  We generally recommend a week home from daycare or school and then they may return with the understanding that they will have a reduced activity for the next week.
     There are many different techniques to remove the tonsils and the adenoids.  You may hear about cold dissection, coblation, electrocautery, microdebriding, laser, and others.  Just remember that these are all tools that your doctor can use to accomplish the goal of removing the tissue that needs to be removed.  This will vary from surgeon to surgeon. 
     Even though this procedure is one of the most common procedures done across the United States, there are still risks involved.  In general, we go through the mouth to remove the tonsils and adenoids.  This places the lips, teeth and gums at risk because they are in the path of getting equipment into and out of the mouth during the procedure.  The risk of a severe injury is rare.  Things to consider include dislodging of a loose tooth and a burn to the lips as potential problems. 
     Bleeding is the risk we tend to worry about the most.  The risk of bleeding from the nose or mouth after removing the tonsils and adenoids is around 1-3%.  That risk has been stable in the literature throughout the years.  Fortunately the chance of severe bleeding is rare, and the chance of needing a blood transfusion or something worse happening is very uncommon.  If there is any bleeding from the nose or mouth after surgery, be sure to contact your doctor.
     Removing the tonsils and adenoids is a painful procedure.  This is likely related to the fact that the tonsils sit in a bed of muscle, and, in addition to that, we are creating a large open wound like a big ulcer in the back of the throat.  Your doctors will give you an appropriate pain regimen for after surgery but you have to encourage your kids to take it.  It is also important that the throat stay well hydrated during this time.  A dry throat after surgery is very painful and can lead to not wanting to drink and more pain until one ends up back at the hospital with dehydration. 
     When the tonsils and adenoids are removed, we are increasing the space in the back of the throat.  Sometimes, it is too much space and the body is not able to compensate for that.  Particularly, the palate can have a difficult time closing the gap between the throat and the nose.  This may result in a change in the voice to a hypernasal quality.  You might think that your child already has a nasal voice from this tissue, but in general, that is a hyponasal voice: an obstructed voice from too much tissue in the back of the throat and nose.  If this happens, it frequently will resolve on its own.  If not, about 1:1,000 children will require speech therapy or potentially even surgery to correct this.
     There are small risks of the adenoids regrowing or scarring in the back of the nose.  These happening to any significant degree is rare, but may mean an additional surgery or medication down the line. 
     For these reasons, we as surgeons try to make sure you as parents are well informed prior to making a decision to go to surgery.  Be sure to ask any questions that you have so that you are able to make the best decision.  After surgery, be sure to contact your doctor after for a fever over 101.5, pain uncontrolled by medication, bleeding, poor oral intake, decreased urination, or any other concerns.

Tonsils and adenoids: not just there to take out!


After a long hiatus, I have returned with anticipation to the blogging arena.  I wish I had a great excuse for being absent for so long.  As time has gone by, however, I realized just how quickly that time has faded into a memory.   

In reflecting on the last 8 months...yes...it has been 8 months since I last wrote... I was trying to think about a topic that I have really needed to address during that time.  Something that I have seen frequently.  Something where trends have changed and new guidelines have been published.  Ah, yes, I know it...we will discuss tonsils and adenoids.

First, let's discuss a little anatomy (click link for picture).  The tonsils and adenoids are part of a surveillance system for the upper airway.  The tonsils sit on either side of the throat at the level of the soft palate and the adenoids sit above the palate at the back of the nose.  Things (antigens) that are recognized as foreign coming into the nose or mouth are identified in these tissues and antibodies (defenses) are made to fight them.  The greatest contributions of tonsils and adenoids to immunity are made in the early years before age 10.  After that, their function decreases, perhaps secondary to the fact that these tissues have seen most of these antigens and do not have to work hard to produce antibodies against them.  This is why the tonsils and adenoids decrease in size, when kids get older, to nearly nothing in most adults.

So one might ask...if the tonsils and adenoids go away eventually, why do they have to be taken out?  That is an excellent question.  By the numbers, tonsillectomy and adenoidectomy procedures have actually decreased over the years due to changes in the criteria for candidacy for the procedure.  Back in the old days, tonsils were frequently taken out because they looked big or for just a few infections.  The current recommendations from the American Academy of Otolaryngology are for tonsils to be removed for infectious reasons for 7 infections in 1 year; 5 infections per year for 2 consecutive years; or 3 infections per year for 3 consecutive years.  These are strict criteria, but they do not indicate that each of these infections has to be strep throat.  Other infectious reasons for surgery could include recurrent peritonsillar abscess.

Nearly 80% of tonsillectomies done today are done for sleep disordered breathing or obstructive sleep apnea.  This is a disease of too much tissue in the back of the throat.  When the tonsils are enlarged, they occupy space in the throat, sometimes creating a blockage when the muscles of the throat relax during sleep.  This can present as snoring, restless sleep, frequent awakenings, and even pauses, choking and gasping during sleep.  This does not mean that all sleep apnea in children is caused by enlarged tonsils, but they are frequently contributing. 

Frequently parents will come into the office with a presumption that the tonsils need to be removed purely because they are big, or for 1 or 2 infections.  Your ENT physician will work with you to get a history of exactly how those big tonsils are affecting your child and what other options are available for treatment.  During your evaluation, some additional workup may be required including a sleep study, a neck x-ray, or potentially laboratory studies.  In our next installment, we will discuss the  procedure including potential risks, surgical considerations, and post-operative expectations.  Please check out Dr. EJ on Twitter @DrEJ76 and like us on Facebook: www.facebook.com/ChildrensENT.
