2. Fig 1
A right lateral view of the skull is marked with superficial and floor of mouth spaces with their subspaces. The superficial space consists of the large buccal and smaller canine space. Three circular dotted lines represent floor of mouth subspaces. These comprise the midline anterior submental space (just below the chin) and bilateral sublingual space and submandibular space which are separated by the mylohyoid muscle. Free communication between these latter two occurs along the posterior border of mylohyoid.

3. Fig 2
A right lateral view of the skull is marked for the masticator and pharyngeal spaces. The submasseteric, pterygomandibular, and temporal spaces comprise the masticator space. They are in close association with muscles of mastication and can lead to severe trismus when infected. The lateral pharyngeal space is positioned close to the masticator space allowing easy spread between them.

These histograms compare inter-incisor distances (sub-grouped by cm width) preoperatively and post-induction for the superficial vs all other spaces. Inter-incisor distances overall tended to increase after induction. There were no individuals with inter-incisor distances <2 cm in the superficial only spaces after induction.
