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.

Beatboxing Protective of the Vocal Cords?

Beatboxing is a popular vocal percussion technique that incorporates use of the entire vocal tract. Recently, research by Dr. Steven Simms (who I had the pleasure of working with briefly when we were both at Yale University in the 1990s) suggested that beatboxing techniques may actually protect against vocal cord injury.

Unlike singing where most of the sustained energy is directed at the vocal cord level, beatboxing makes extensive use of the entire vocal tract, especially the muscles of the throat.

Although more research is needed, it is not inconceivable that beatboxing techniques may potentially be helpful to patients who have suffered from vocal cord injury. The question is what techniques specifically and how it can be incorporated into voice therapy sessions. Furthermore, such vocal techniques may be more "acceptable" to teenagers who may scoff at more traditional strategies.

Check out this fiberoptic laryngoscopy video of a beatboxing artist.

Acupuncture Helps with Ear Surgery Pain

Researchers at Boston Children's Hospital has found that acupuncture may be effective in diminishing both pain and post-anesthesia agitation in children after ear tube placement determined thru a prospective randomized controlled trial.

Typically, children are placed under general anesthesia in order to have this procedure performed and upon waking, are often tearful and agitated. In this study, acupuncture needles were placed at LI-4 and HT-7 immediately after anesthesia, but prior to ear tube placement.

A blinded assessor than determined that pain and agitation were significantly lower in the acupuncture group compared with controls during the 30 minutes after surgery. Furthermore, the number of patients who required analgesia was considerably lower in the acupuncture group than that in the control group.

Although promising, in order to be fully convinced of the effectiveness of acupuncture, further research by other groups in larger number of kids need to be performed.

BUT... because the risks and side effects are so nominal, it can't hurt to give it a try for those patients and families interested in doing so.

For full disclosure, I personally have no experience in providing acupuncture and I would suggest taking these research findings to a reputable and licensed acupuncturist to get this done in those who are interested.

Bengals Punter Kevin Huber Suffers Jaw Fracture During Game

Courtesy of Jeffrey Beall from Wikipedia

This past weekend, Cincinnati Bengals punter Mark Huber suffered a broken jaw when he was viciously knocked to the ground by Steelers Terence Gavin who lead the tackle with his helmet. [link]

Given bleeding from the mouth, there is the possibility of an open fracture extending into the mouth, though it could also be from a self-inflected bite when Huber got hit.

Unlike most facial fractures that do NOT require any surgical intervention, most jaw fractures do need to be surgically repaired and typically entail wiring the jaw shut. Often, a metal plate with screws will be utilized to stabilize the fracture as well.

The reason the jaw is wired shut is so that as the broken bone heals, it heals in such a way that the way the teeth comes together is normal (in essence, the teeth act as the cast for the jaw fracture). Of course, eating is limited to liquid diet and dental care is important as brushing the teeth thoroughly will be impossible.

Also, it is easier to precisely place the metal plates after the jaw is wired shut. In Huber's case, metal plates will almost certainly be utilized as it allows for faster healing, sooner removal of jaw wiring, and quicker return to normalcy.

The wires holding the jaw shut can be removed after a few weeks, but exact duration depends on the fracture location and severity.

With this type of facial fracture, it will be unclear when exactly he will be able to return play.

Acupuncture Alleviates Pain After Tonsillectomy in Children

The study showed that acupuncture significantly decreased pain after tonsillectomy in children (2-17 years of age) with reported pain levels before acupuncture of 5.52 (SD=2.28) out of 10 which fell to 1.92 (SD=2.43) after acupuncture.

This retrospective research was conducted in 31 patients who underwent a tonsillectomy within a 3 month period of time by Dr. James Ochi, one of only a handful of dual board-certified ENT and medical acupuncture in the United States. No study patients received any narcotics for pain control beyond tylenol, ibuprofen, and a single dose of intra-operative dexamethasone. The tonsillectomy itself was performed using electrocautery set at 24W.

The acupuncture points used for pain control are shown below and was performed bilaterally:

Image taken from the Research Paper

All patients received acupuncture at LI4 (between thumb and index finger). Additional points were found effective in relieving tonsillectomy pain and provided on an as needed basis at (in decreasing frequency) CV23, GV24.5 and GV20. Acupuncture points LI20, LI11, and LI10 were utilized in only a few patients.

LI4 point is hypothesized to work so well because:

"Stimulation at LI4 increases activity in the somatosensory cortex and a region of the brainstem known as the periaqueductal gray area, as revealed by functional magnetic resonance imaging, that are involved in processing pain signals." [link]

Although promising, in order to be fully convinced of the effectiveness of acupuncture for post-tonsillectomy pain, further research that is prospective, randomized, and controlled is required.

BUT... because the risks and side effects are so nominal, it can't hurt to give it a try for those patients and families interested in doing so.

For full disclosure, I personally have no experience in providing acupuncture and I would suggest taking these research findings to a reputable and licensed acupuncturist to get this done in those who are interested.

Two New Sublingual Allergy Tablets Approved by FDA Advisory Committee

This week, the FDA Allergenic Products Advisory Committee unanimously supported approval for two new sublingual allergy tablets (Oralair and Grastek) that work the same way allergy shots do... but instead is dissolved under the tongue at home instead of a shot in the arm in a medical office. Although both tablets have been available in Europe for some time, final "official" FDA approval may not occur until end of 2014 (or later) for sale/distribution under prescription in the United States.

Oralair is made by a French pharmaceutical company Stallergenes and treats patients aged 10-65 years who are allergic to 5 different grasses: Sweet Vernal, Orchard, Perennial Rye, Timothy, and Kentucky Blue Grass. Treatment is composed of a buildup and maintenance phase. Starting 4 months prior to the grass pollen season, a 100 IR tablet is administered under the tongue in a medical office to ensure no significant side effects. At home on day 2, two 100 IR tablets are administered. On day three and daily thereafter, a 300 IR tablet is placed under the tongue until the end of the grass pollen season. The tablets take about 1 minute to dissolve.

Grastek (aka Grazax in Europe) is made by ALK-Abello and Merck and treats patients aged 5-65 years who are allergic to only Timothy Grass. Grastek has a simpler regimen of 1 sublingual tablet daily starting 12 weeks before and continued until the end of the grass pollen season. As with Oralair, the first dose is given in a medical office to ensure safety with all other doses are taken at home. The tablet dissolves in less than 10 seconds.

For both tablets, epipen needs to be available at home due to possible risk of anaphylaxis. As with allergy shots, patients on beta-blockers for high blood pressure are not eligible to undergo this treatment.

The Nose is a Jungle of Germs (even in Normal Healthy People)!

A fascinating study was conducted by Stanford researchers on the amount and types of germs found inside the nose in normal healthy individuals, whether they are staph carriers or not.

In a typical nose in a healthy individual without any symptoms, the following "germs" can be found. Keep in mind that ALL these germs have the potential to cause a pathological sinus infection:

• Corynebacterium
• Propionibacterium
• Escherichia-Shigella
• Staphylococcus aureus (including MRSA)
• Staphylococcus (other species)
• Dolosigranulum
• Tomitella
• Moraxella
• Actinobacteria
• beta-Proteobacteria
• Prevotella
• Anaerococcus
• Streptococcus
• Peptoniphilus
• Variovorax

These germs were found not just in the nostril, but also on the middle turbinate located about 1-2 inches into the nose and the sphenoid recess located in the very back upper part of the nose (about 3+ inches into the nose).

The top 2 most common germs found in healthy individuals were corynebacterium and propionibacterium. When these bacterial populations decrease, the presence of staphylococcus increases.

Staphylococcus was also found not just at the nostril where cultures are most commonly obtained, but in both much deeper locations within the nose.

This may explain why in spite of aggressive whole body MRSA body hygiene management and use of bactroban ointment to the nares not uncommonly fails to eradicate staph/MRSA in susceptible patients.

Clearly, more research is needed, especially in how to minimize/eradiacate staph colonization beyond the nostril (but allow for normal, healthy bacteria to remain).
