A sinus infection is of course an infection of the sinuses which are the passages that run between our nasal passages and our oral cavity etc. An ethmoid sinus infection in particular is an infection that is in the frontal sinus between the eyes and which causes inflammation resulting in pressure on the eyes and nose.

Symptoms of Ethmoid Sinus Infection

  • Nasal congestion and discharge
  • Postnasal drip
  • Pressure and pain on the eyes creating headache
  • Pain on one side of the nose
  • Headache in the temples
  • Pain relief when standing up or keeping your head upright

These symptoms are usually acute lasting around 10 days and can be eased with a decongestant used to clear the airways such as Afrin, Naphcon or Neo-Synephrine. In some cases antibiotics can be prescribed by your doctor in order to kill off the bacteria causing the infection, as can a synthetic penicillin such as Amoxil or Trimox.

There are also many preventative measures you can take to avoid ethmoid sinusitis such as washing your hands regularly when you have a cold or are around those with a cold. Getting a flu jab can also prevent this by preventing the virus.

Ethmoid Sinus Infection Causes

The ethmoid sinuses are located in the skull just above the nose between the two eye sockets. These contain small cavities which connect and these are lined by mucus membranes. If bacteria infects this lining it can cause the membranes to become inflamed and this causes them to block the ostia and this prevents mucus from draining. This will then build up resulting in the ethmoid sinusitis.


It is important to seek medical attention if you suspect you have an ethmoid sinus infection as it can cause blood clots in the side of the face otherwise which can result in an eye socket infection, the results of which can be permanent blindness and an inability to move the eyes.
