That Popsicle stick is such a pain in the neck!
How many times do I have to yell at my kids for jumping around with sticks in their mouths? Seriously… playing basketball with a lollipop in your mouth isn’t a great idea children!! But nevertheless, inevitably, a child is going to present to you with an intraoral / oropharyngeal injury suffered as a result of a stick-like object in the mouth getting thrust backwards.
- The incidence of this situation seems palpable, but actual numbers are not known.
- Potential Complications that must be considered during the evaluation:
- Often stops prior to arrival
- Peristent hemorrhage (the palantine, jugular, and carotid vessels live right behind there) can life threatening
- Often is small, puncture like… and the depth can be deceiving
- Large avulsions or through and through soft palate injuries may actually require operative closure, but the vast majority do not require closure
- Retained Foreign Bodies
- May lead to localized infection
- Cases also exist of severe retropharyngeal abscess, mediastinitis, and sepsis.
- ENT literature often advocates for empiric antibiotics; however, this has not been proven to be necessary. Others advocate for antibiotics only for large wounds that require closure. Use you best judgment.
- CNS insult
- Penetrating trauma may lead to carotid artery dissection or pseudoaneurysm formation.
- Significant blunt trauma can also produce inflammatory response significant enough to lead to thrombus formation within the carotid artery.
- Either way, it isn’t good for the brain.
- Neurologic symptoms can present shortly after the injury or in a delayed fashion (1-3 days or even years).
- This is naturally the biggest concern: fortunately it is extremely rare – but that does generate the biggest dilemma: For this severe complication that is very rare, what is the appropriate evaluation?
- Thorough H+P (naturally) – but make sure you get a good visual inspection of the area (although I wouldn’t probe it!!)
- Lateral Neck film
- May help identify foreign bodies
- May show free air (not sure of the true relevance of this).
- While I would really like to say that this is a well-studied and valid approach to investigate for large blood vessel injury, I cannot find any specific literature to advocate for the use of ultrasound in this setting.
- Perhaps this would be a good research project… but it would have to be done over a long period of time because there won’t be that many true injuries.
- CT Angio
- Reported to have a sensitivity of 90-100% and specificity of 98.7-100% for detecting carotid injury.
- There is NO CONSENSUS on who requires a CT:
- Unstable patients, difficult to assess patients (uncooperative), or those in whom you are concerned for vascular injury should get a CTAngio (naturally).
- Recall that the appearance of the wound can be deceiving (and you don’t even need to have a puncture to lead to thrombosis of the carotid).
- Injury (puncture or bruising) over the lateral aspects of the posterior pharynx / tonsillar pillars is more concerning than a midline injury.
- Difficult to draw the line of what is reasonable when you are trying to balance a large dose of radiation plus IV contrast versus a very rare but potentially severe complication.
- If you do not image, VERY STRICT anticipatory guidance and discharge instructions need to be clearly discussed (get back to the ED pronto at the first suspicion of any neurologic finding!).
