An infection in what fascial space can result in a spread to the mediastinum via traversing retropharyngeal and prevertebral spaces?

  1. Submandibular

  2. Canine

  3. Lateral pharyngeal

  4. Masticator

The correct answer is: Lateral pharyngeal

An infection in the Submandibular fascial space mostly spreads downwards towards the front of the neck. An infection in the Canine fascial space mostly spreads outward towards the side of the face. An infection in the Masticator fascial space mostly spreads towards the back of the mouth. All of these directions are away from the mediastinum and do not involve the retropharyngeal and prevertebral spaces. The Lateral pharyngeal fascial space is the only option that is located close enough to the retropharyngeal and prevertebral spaces to potentially allow for spread to the mediastinum.
