ANATOMY OF THE HUMAN EYE

For ophthalmologists, optometrists, medical, dental, and optometry students, eye-anatomy forms the basis for eye-pathology in diseases: dry eye, retinal detachment, macular degeneration, diabetic retinopathy, eye-trauma etc.

What are the paraorbital sinuses?

The paraorbital sinuses include the frontal sinus above the orbit (orange), the ethmoid sinuses (green) in the medial wall of the orbit, the sphenoid sinus (blue) that is posteriorly located and the maxillary sinus (purple-pink).


Below, the sinuses are shown in a sagittal view. The maxillary sinus (red-pink) and the ethmoid sinuses would not be visible in the midline plane that shows the drainage from the sinuses (arrows). It is evident that the maxillary sinus is close to the teeth. Pain from the sinus may be referred to teeth. This occurs in maxillary sinus infections. Occasionally, normal teeth have been removed from patients with life threatening fungal sinus infections because this source of referred pain was unrecognized.

Most people suffer from sinusitis eye pain due to sinus infections and pressure. Eye pain associated with sinus infections usually clears once the sinus pressure dissipates.

Not all toothaches are caused by problems in your teeth. Sinuses can also cause tooth pain. If you experience continuous pain in the back of your upper teeth that changes when you move your head, it could be maxillary sinusitis.

The maxillary sinuses are connected to the upper tooth roots. You will experience symptoms similar to sinusitis when you have upper teeth bacterial infection.

I agree with the last comment. Any kind of infection that includes the upper teeth may experience signs and symptoms related to sinusitis. According to my fredericksburg dentist, it is important to treat sinusitis for this can cause halitosis.
