1. A cheek retraction device comprising:
a member forming an arm extending between and connecting a first retractor and a second retractor, the first and second retractors opposed to one another, each of the first and second retractors extending from a first lower end region to a second upper end region and sized to receive a portion of a lip of a patient, wherein the first retractor defines a first internal passage and a first aperture, and wherein the second retractor defines a second internal passage and a second aperture, wherein the arm extends between and connects the first lower end region of the first retractor to the first lower end region of the second retractor;
a nasal tube defining a third internal passage, the nasal tube extending between and mechanically coupling the second upper end region of the first retractor and the second upper end region of the second retractor, the nasal tube in fluid communication with the first and second passages, the nasal tube being opposite to the arm, the nasal tube defining a third aperture;
a fluid connector supported by the arm and in fluid communication with the first and second passages, the fluid connector to connect the cheek retraction device to a remote vacuum source;
wherein the first aperture and the second aperture face towards one another such that aerosols flow from an oral cavity of a patient into the first and second passages via the first and second apertures; and
wherein the third aperture faces away from the arm such that aerosols flow from a nasal passage of the patient into the third passage via the third aperture.
