What is the most common sinus affected in sinusitis?

I assume its Nasal, am I correct?, then my next question is what is the most affected paranasal sinus affected? (My guess is maxillary....) Anyone know for sure about the above two questions? Thanks so much.

PLEASE ANSWER THIS IF YOU KNOW... THE FIRST ANSWER WAS GREAT, IF I WAS ASKING THAT QUESTION - BUT IM NOT, IM ASKING THE MOST """COMMON""" not what sinuses are :o) thanks

Sinusitis is an inflammation of the paranasal sinuses....
Maxillary sinusitis - can cause pain or pressure in the maxillary (cheek) area (e.g., toothache, headache)
Frontal sinusitis - can cause pain or pressure in the frontal sinus cavity (located behind/above eyes), headache
Ethmoid sinusitis - can cause pain or pressure pain between/behind eyes, headache
Sphenoid sinusitis - can cause pain or pressure behind the eyes, but often refers to the vertex of the head

Bacteria are the most common direct cause of acute sinusitis
The maxillary sinuses (behind the cheekbones) are the most common sites.
The ethmoid sinuses (between the eyes) are the second most common sites affected by colds.
The frontal (behind the forehead) and sphenoid (behind the eyes) sinuses are involved in the balance of cold-related cases (about a third).

Although inflammation in any of the sinuses can lead to blockade of the sinus ostia, the most commonly involved sinuses in both acute and chronic sinusitis are the maxillary and the anterior ethmoid sinus.

These cavities, located within the skull or bones of the head surrounding the nose, include the frontal sinuses over the eyes in the brow area, the maxillary sinuses inside each cheekbone, the ethmoids just behind the bridge of the nose and between the eyes, and behind them, the sphenoids in the upper region of the nose and behind the eyes.
Sinusitis has its own localized pain signals, depending upon the particular sinus affected. Headache upon awakening in the morning is characteristic of sinus involvement. Pain when the forehead over the frontal sinuses is touched may indicate inflammation of the frontal sinuses. Infection in the maxillary sinuses can cause the upper jaw and teeth to ache and the cheeks to become tender to the touch. Since the ethmoid sinuses are near the tear ducts in the corner of the eyes, inflammation of these cavities often causes swelling of the eyelids and tissues around the eyes and pain between the eyes. Ethmoid inflammation also can cause tenderness when the sides of the nose are touched, a loss of smell, and a stuffy nose. Although the sphenoid sinuses are less frequently affected, infection in this area can cause earaches, neck pain, and deep aching at the top of the head.
