How Long Do Swallowing and Voice Problems Last After C-Spine Surgery ACDF?

I often see patients for swallowing and/or voice difficulties after cervical spine surgery (ACDF). In the vast majority of cases, reassurance that such "side effects" are not uncommon is the only thing I need to provide after a complete exam.

After all, both the voice box and swallowing tube are manipulated and pushed over to one side in order to perform cervical spine surgery from an anterior approach. Check out the video below that illustrates how this happens.

Beyond reassurance, the next question patients have is how long before things go back to normal. Until now, that was a hard question to answer.

A recent report was able to provide some numbers I can now use to help explain to patients. After anterior approaches to cervical spine surgery:

• 60% had a postoperative issue, including 27% with postoperative voice complaint and 48% with postoperative swallowing complaint
• Swallowing complaints that lasted beyond 1 year occurred in 28%
• Voice complaints that lasted over 1 year occurred in 9%
• Approaching spinal levels above C4 and exposing more than 3 spinal levels were 2 factors that significantly resulted in voice and swallowing problems

In certain patients with more extreme swallowing difficulties, barium swallow studies may be ordered. Swallow therapy can be helpful as well.

Should vocal cord paralysis be seen on endoscopy, voice therapy and even vocal cord medialization injections can be performed to alleviate voice problems.

Tracheostomy Fire During Surgery Burning Patient

Image from Wikipedia

In early 2012, a surgeon was performing a trach (breathing hole in the neck) when the oxygen used during the procedure caught fire severely burning the patient. Apparently, the surgeon used an electrocautery device which most likely emitted a spark igniting the oxygen being given to the patient leading to the fire. [link]

What happened?

Tracheostomy procedures are performed typically in very sick patients who have been intubated for a prolonged period of time. Often, such patients require higher concentrations of oxygen than normal in order to maintain oxygen levels in the body.

Problem in this scenario is that higher concentrations of oxygen also mean a higher risk of accidental fire when using instruments that help stop bleeding like an electrocautery device.

During a tracheostomy, an opening is created in the windpipe (watch video below). This allows oxygen that is being given to the patient to leak out into the surgical field. If electrocautery is used in this oxygen rich environment, any spark from an electrocautery device can lead to ignition and a flash fire.

Typically, in order to minimize this risk of fire, the surgeon should avoid using any electrical instruments in the surgical field that may create a spark after entering into the airway. Cutting into the airway would allow oxygen to escape into the surgical field. That usually means meticulous surgical technique and controlling all bleeding BEFORE cutting into the airway. If possible, reducing the oxygen given to the patient as much as possible is also beneficial.

Nitrous oxide should be avoided as an anesthetic agent as it is also ignitable like oxygen.

If electocautery use is unavoidable after the airway is surgically entered, the endotracheal tube cuff should re-inflated and advanced past the tracheostomy incision. Vacuum suction should be applied to evacuate as much oxygen from the surgical field and if possible, a period of apnea while cautery is applied.

Life-Saving Emergency Trach Performed in Restaurant

On Sept 23, 2013, a physician performed a life-saving emergency tracheotomy in a restaurant on a patron who was choking on a piece of meat. [link]

While eating dinner at The Mark Restaurant in California, Dr. Royce Johnson, an infectious disease doctor affiliated with UCLA, performed this procedure on Pauline Larwood, a female supervisor and a community college trustee.

Dr. Johnson saved this woman's life using a pocket knife and the hollow cylinder of a pen after a Heimlich maneuver failed to work.

Interestingly, Dr. Thomas Frieden, director of the CDC, who was also present in the restaurant assisted in the care by monitoring Larwood’s pulse during the incident.

Also present in the restaurant witnessing the emergency procedure were:

• Francis Collins, MD (director of NIH)
• Farming and business moguls Lynda and Stewart Resnick
• Rep. Kevin McCarthy, R-Bakersfield
• Assemblywoman Shannon Grove, R-Bakersfield
• State senator Jean Fuller, R-Bakersfield

Although typically surgeons are the individuals trained to perform tracheotomies, bravo to Dr. Johnson who took the initiative in spite of the fact that he probably has never performed one.

I should also add that though media reports state that an emergency tracheostomy was performed, it is probably more likely that an emergency cricothyroidotomy was performed instead which is easier and less "bloody."

Malpractice Lawsuit for Nerve Damage Sustained After Neck Cyst Excision

Earlier this month, a malpractice lawsuit resulted in a $4 million dollar award to the patient plaintiff who suffered permanent nerve damage after a family practice physician excised a cyst from the neck. [link]

Briefly, the patient visited the family physician in July 2009 for a lump in his left neck. The family physician recommended that the mass be surgically excised which was subsequently performed by the same family physician (not a surgeon) in the office. After the procedure, the patient experienced a weakened left arm and shoulder and had difficulty picking things up with that arm or moving the arm more than 90 degrees. Subsequent evaluation by an orthopedic surgeon and neurosurgeon determined that the spinal accessary nerve was cut at the time of the neck mass excision.

So what probably happened?

The spinal accessory nerve (also known as cranial nerve XI), is a major nerve that comes off the spinal cord and supplies motor function to the shoulder and arm (red arrow below pointing to the nerve which is yellow).

Image Modified from Wikipedia

I suspect that in this case, the mass was located in the same area denoted by the red arrow above. Now assuming that media and court documents were correct that it was truly a cyst that was excised, the cyst must have laid right below the skin, but on top of the nerve.

Careless excision of the cyst would have resulted in this nerve being cut especially during dissection on the mass's deepest aspect, especially if the physician did not hug the mass during dissection. Using an analogy, good surgical technique is like peeling an orange without puncturing the yummy orange underneath. Poor surgical technique would be peeling the rind and taking bits of the edible orange as well... or leaving some nasty rind on the fleshy orange itself.

Often, novice surgeons take large cuts around a mass with the tip of the scissor or scalpel extending beyond visualization. Also, thick layers of tissues are cut rather than thin transparent amounts. Furthermore, when a mass is grasped and pulled, anatomic structures like a nerve can get pulled out of its usual location along with the mass which can lead to unintentional damage. 

As such, experienced surgeons know when to cut big (no important structures are around) and when to cut in tiny microscopic degrees (important nerves and blood vessels are around).

The neck has a large number of important blood vessels and nerves in a highly compacted area making surgery in this part of the body potentially fraught with peril. However, there are certain "safe" areas where no significant important nerves or blood vessels are found. Such a "safe" zone from a nerve perspective is right under the chin extending down over the voicebox. Of course, there are other important structures located in this area that could get damaged even if nerves aren't a concern.

Possible Blood Test for Oral Cancer Caused by HPV?

There might be a blood test which can possibly predict individuals who may develop oral cancer caused by HPV years before it happens. HPV, an abbreviation for human papilloma virus, encompasses over 100 different strains among which only a few can cause problems in humans. Specifically, HPV 16 can lead to cervical cancer in woman and oral cancer in both genders.

HPV triggered oral cancer is also the most common cause of oral cancer now exceeding even smoking and drinking alcohol.

Unlike HPV that causes cervical cancer which can be screened for by pap smears in women, there's currently no good screening test to look for HPV that might cause oral cancer.

However, that's not to say that researchers aren't busy looking for just such a test...

In June 2013, researchers published a possible blood test that might predict those individuals at risk for developing HPV oral cancer.

By analyzing blood samples taken from 638 patients with head and neck cancers, they discovered that antibodies against HPV16 E6 was present in pre-diagnostic samples for 34.8% of patients with oropharyngeal cancer and 0.6% of controls (healthy patients without cancer). Furthermore, HPV16 E6 was NOT associated with other cancer sites. The increased risk of oropharyngeal cancer among HPV16 E6 seropositive participants was independent of time between blood collection and diagnosis and was observed more than 10 years before diagnosis.

Now I should state that HPV16 E6, which is actually a gene found in the virus, only accounted for 34.8% of patients. It bears repeating... it was positive only 34.8% of the time. In other words, this test predicted oral cancer only one out of every 3 patients who actually developed cancer.

As such, it is not a very specific test... ideally, you want a number as close to 100% as possible, otherwise patients who test negative to this blood test may falsely think they are not at risk.

Now, the other problem is what if a patient DOES test positive to HPV16 E6?

Does that mean such patients need to undergo routine fiberoptic endoscopy screening examinations every few months or years? Are biopsies required or not if visual examination appears normal? If biopsies are required, how often and from where? After all, oral cancer encompasses the tongue, tonsil, pharynx, larynx, supraglottis, palate, buccal mucosa, etc, etc, etc. That's a lot of biopsies...

Coincident with the development of a good blood test is the need for research to develop a protocol of what to do with the results of such test information.

Actress Sofia Vergara Underwent Total Thyroidectomy for Thyroid Cancer

Actress Sofia Vergara, best known for her role in the TV hit comedy Modern Family, had her entire thyroid removed for thyroid cancer when she was 28 in 2000. This was followed by radioactive iodine therapy and now takes a daily thyroid hormone replacement for her hypothyroidism.

Image by Jenn Davis from Wikipedia

Thyroid cancer is typically first suspected on a routine examination if a neck mass consistent with a thyroid nodule is palpated. An ultrasound of the neck is typically performed to characterize the thyroid mass further which is than followed by a biopsy. Should the biopsy come back malignant, thyroid removal surgery is performed. Even if the biopsy comes back indeterminate, surgery may still be pursued to be on the safe side.

Other studies may be pursued including CT scan and a thyroid nuclear scan.

Although the type of thyroid cancer Sofia Vergara had was never revealed, she most likely had papillary thyroid carcinoma which is the most common form of thyroid cancer and is highly curable (which is where the comment of being a "good" cancer comes from).

Other less common thyroid cancers include follicular thyroid carcinoma and medullary thyroid carcinoma.

It should be mentioned that until the thyroid is removed, one can NOT be absolutely sure that thyroid cancer actually truly is present. Indeed, the president of Argentina announced that she had thyroid cancer only to find out after her thyroid was removed that no cancer was actually present. Read blog post about this "mistake".

Why Do Biopsy Results Take So Long? [video]

One of the most common questions I get after a surgical procedure is how long it takes before biopsy results are back... especially when a mass was removed and there is a cancer concern.

Does it take a few hours? 24 hours? Days?

Disappointingly, it can take up to 7 days if not longer.

You want to know why?

Well, rather than explaining, watch a 6-minute video that explains the numerous steps that goes into providing a diagnosis after a mass is removed... in this particular case, a neck mass though the same steps apply to any mass removed from anywhere else in the body.

Special thanks to Robin Earl who spent hours hanging out in the pathology lab video-taping all the relevant video clips as well as Fauquier Health System for allowing this video to be made!

Coffee Reduces Risk of Death from Oral Cancer

In a prior blog, I mentioned that researchers found that regular coffee drinkers who drank more than four cups of coffee a day had a 39 percent decreased risk of two types of head and neck cancer: oral cavity and pharynx cancers. In the study published in the Journal of Cancer Epidemiology, Biomarkers & Prevention, they found however, that coffee did not decrease the risk of laryngeal cancer. Read a CNN report on this here.

In a more recent study (Dec 2012), researchers have found that not only does coffee reduce risk of cancer, but that consuming more than four cups of caffeinated coffee per day was associated with a 49 percent lower risk of oral/pharyngeal cancer death relative to no/occasional coffee intake.

Coffee contains over 1,000 different chemical compounds, including cancer-fighting antioxidants, and it’s those antioxidants that may provide a “plausible explanation” for reducing the cancer risk as well as cancer death.

However, patients should not take this study as an excuse to increase their coffee intake specifically to counteract known cancer-causing behaviors including smoking, drinking alcohol, and chewing tobacco.

Celebrity Actors Who Have Received a Trach (Catherine Zeta Jones Included)

Image Taken From www.TopScarCream.com

Tracheostomy (also known as trach) is when a hole is made in the midline neck directly into a person's windpipe (watch video). Although many people may shy away from this deforming procedure, it can be life-saving.

On that note, here is a short list of famous celebrity actors who have undergone an emergency trach for one reason or another:

Catherine Zeta-Jones
Apparently, when she was a child, she had an emergency trach done. She still has a 1.5 inch scar from this procedure which she elected to not have removed [link].

Gary Coleman
He was hospitalized for 3 months due to complications from thyroid surgery for which he underwent an emergency trach [link].

Watch video of thyroid surgery.

Elizabeth Taylor
In spring of 1961, she developed a case of pneumonia which led to an emergency trach [link].

Christopher Reeve
Of the original Superman fame, he became paralyzed from the neck down after a horse-riding accident. A tracheostomy was required for him to breath due to ventilator dependence. [link]

ENT Surgeons Who Use daVinci Robot

Readers know my skepticism on the practicality of the daVinci robot in ENT head and neck surgeries.

However, that does not mean that I do not doubt its effectiveness in certain unique situations... as well as market forces that use such high (and expensive) technology to market a given hospital's services.

In any case, plenty of patients have asked me if there's any ENT surgeons who use the daVinci robot in the region.

There are... and here are two that I am aware of.

Creative Ways to Wear a Scarf for Patients with a Trach or Ugly Neck Scar

[Watch the video below!!!]

Given I operate on the neck not uncommonly... a common fear for a patient is how the incision will look afterwards. For a simple neck mass excision, the incision almost always heals just fine to the point nobody will notice the scar.

However, this concern is multiplied a hundred-fold when a patient undergoes a tracheostomy (hole in neck) for severe obstructive sleep apnea or for some other airway reason. It could even be a laryngectomy where the entire voicebox is removed for cancer reasons. 

Who wants everybody to know that there's a hole in the neck... especially for a woman??? Even if there's no hole, sometimes the scar IS noticeable, especially after thyroidectomy, and therefore undesirable.

Scarring from an incision can potentially be addressed with dermatologic procedures, but if no surgery is desired and honestly, what really can be done with a hole defect in the neck... it really boils down to a scarf of some kind to obstruct the neck from causal view.

I mistakenly thought there's only 2 ways to wear a scarf around the neck.

The video below shows 25 ways to wear a scarf! Even if a patient or an individual decides NOT to wear a scarf ever... you should STILL watch the video. The video editing is AMAZING!!!

The actress in the video is Wendy Nguyen who is a prolific fashion blogger who my wife pointed out to me one day.

How Does Cervical Spine Surgery Potentially Cause Voice and Swallow Problems? [video]

It is not unusual for an ENT surgeon to see patients with swallowing and voice difficulties after cervical spine surgery. In particular, the ACDF surgery (Anterior Cervical Discectomy and Fusion).

The key to understanding these issues is to first understand the anatomy involved.

The cervical spine is located in the back of the neck. In front of this spine is the esophagus (swallowing tube) and voicebox.

As such, when a spine surgeon goes through the FRONT of the neck in order to perform cervical spine surgery located in the BACK of the neck, (s)he has to move the esophagus and voicebox over to the side.

A plate is than fixated to the spine to fuse the cervical vertebral bodies.

Because of such manipulation of the esophagus and voicebox, it is not uncommon for a patient to complain of hoarseness and difficulty swallowing after surgery.

Fortunately, such problems usually dissipate with time, but not always. Swallowing complaints may last over 1 year. [more info]

Watch the video describing ACDF and how it can affect voice and swallow.

Strong Sneeze Broke Woman's Neck

Fox News reported yesterday about an Australian woman, Monique Jeffrey, who sneezed SO hard that she broke her neck... literally.

According to the neurosurgeon the patient eventually saw, her C1 and C2 vertebrae had dislocated and were displaced which resulted in her symptoms of excruciating pain with her head locked to her right shoulder and in too much pain to move anything but her right arm. Her left arm was also numb with tingling.

She was placed in a halo traction for three months with weights to gradually move the vertebrae back in alignment.

Carpenter Shoots Himself in the Neck with Nail Gun

According to Boston News, in early December 2011, a carpenter accidentally discharged a nail gun and embedded a 3.5 inch nail in the bottom of his neck. Based on the CT scan included here, it appears the nail entered the neck dead center given the clear appearance of the windpipe.

Based on the location, the anatomic sequence of nail piercing is as follows:

Skin --> Thyroid Gland --> Trachea --> Esophagus Back Wall --> Cervical Vertebral Body

The damage to skin, thyroid, and trachea is not a big deal... In fact, one can consider this a mini-tracheostomy. Minimal bleeding would be expected.

However, the hole between the trachea and esophagus is another matter which may heal well... or not. The esophagus is the swallow tube which transports food from the mouth to the stomach. A hole in the esophagus to the trachea (tracheo-esophageal fistula) would allow swallowed food/liquid to pass from the esophagus over to the trachea and into the lungs leading to pneumonia and bronchitis. This uncontrollable aspiration can potentially be life threatening as the hole could also allow food to pass BETWEEN the trachea and esophagus right down to the heart leading to possible mediastinitis (inflammation/infection of the heart lining).

Treatment initially would be placement of a feeding tube and a long course of IV antibiotics. If the hole does not spontaneously close, it would require surgical closure, typically with a flap of some kind.

The easiest test to perform to determine whether the hole has closed up or not is a swallow study using gastrografin or barium. Watch a video of how this test is performed.


As the news story mentioned, he was VERY lucky the nail went in where it did. If it went in a little further to the right or left, it could have punctured his carotid or jugular vein and he would have bled to death.

A Vampire Who Knows How to Bite Correctly (Anatomically)

Take a look at the pictures below... Which victim suffered a vampire attack who knew what it was doing?

If you guessed the middle, you are correct!

The large blood vessels in the human neck (carotid artery and jugular vein) are oriented vertically, so an experienced vampire who knows the anatomy and desires a good feast of blood would want to bite in the same direction. The other bites were probably committed by vampires with a total lack of experience.
