Which fascial space is above the mylohyoid and swelling would be evident on the floor of mouth?

  1. Sublingual

  2. Submandibular

  3. Retropharyngeal

  4. Parapharyngeal

The correct answer is: Sublingual

Above the mylohyoid muscle lies the sublingual space. If there is swelling in this area, it would be visible on the floor of the mouth. The submandibular space is below the mylohyoid muscle, the retropharyngeal space is behind it, and the parapharyngeal space is lateral to it. Therefore, these options are incorrect for this question.
