Chapter 67 : Laryngeal and Esophageal Trauma Flashcards
True/False: Laryngeal injury is confounded by the process of calcification, which begins during the 3rd decade of life and affects women to a greater degree than men.
FALSE
Historically, this has been the main cause of external laryngeal trauma.
motor vehicle accidents
Suicidal/Homicidal strangulation: This is more likely to cause laryngotracheal separation and concomittant neurovascular injuries
homicidal strangulation
This is the most common presenting feature of laryngeal trauma
hoarseness
True/False: Endotracheal intubation is the preferred method of airway control in laryngeal trauma
FALSE
If endotracheal intubation has been performed, it should be converted to a tracheotomy no longer than __ hours
24
True/False: According to NEXUS low-risk criteria, cervical spine radiography may not be done for trauma patients unless they exhibit all of the listed criteria
FALSE
Schaefer-Fuhrman Classification of Laryngeal Trauma: Complete laryngotracheal separation
Group 5
Schaefer-Fuhrman Classification of Laryngeal Trauma: Edema, hematoma, minor mucosal disruption without exposed cartilage; nondisplaced fracture; varying degrees of airway compromise
Group 2
A stridulous patient with respiratory distress at presentation should immediately proceed to __________
tracheotomy/LA
What is the next step if the airway is judged to be stable following initial history and examination?
flexible nasoendoscopy
For the timing of repair, we aim to repair all laryngeal injuries within __ hours of presentation
12 hours
Primary indication for stenting
significant framework comminution
(Anterior/Posterior) dislocation is usually caused by extubation, and the vocal fold on the affected side will tend to lie higher
Posterior
(Anterior/Posterior) dislocation is usually due to injury from the tip of the anesthetic laryngoscope at intubation. The vocal fold tends to lie lower on the side of the injury
Anterior
Any repairs to the vocal folds should be followed by strict voice rest for ______
48 to 72 hours
In patients with cricotracheal separation, the neck is kept in flexion for __ days postoperatively to prevent traction on the anastomosis.
7
In patients with a normal vibratory appratus structure and unilateral vocal cord paralysis, definitive medialization procedures should only be attempted after __ months of observation for functional recovery
6
True/False: The laryngeal mucosa is more firmly adherent to the cartilaginous framework in infants and children compared with adults, thus, making is less vulnerable to injury.
FALSE
The most common cause of laryngeal trauma
endotracheal intubation
In esophageal injuries, nothing by mouth status is usually maintained for ____ days and healing is assessed with a contrast swallow study using a water-based contrast agent
8-10 days
Esophageal injury: circumferential exudation
third-degree injury
True/False: The absence of oropharyngeal injury does not exclude an esophageal injury
TRUE
