Maxillary Sinusitis

Sinus infections can occur from viruses, fungi or bacteria and from inflammation caused by allergies or abnormal growths. Signs and symptoms of a maxillary sinus infection may appear suddenly and resolve on their own, or they may become chronic and require treatment. When the breast becomes infected, or irritated by allergy, it is called sinusitis. Signs and symptoms of maxillary sinus infection can simulate toothache or migraine. Recognizing a maxillary sinus infection and understanding when to seek treatment is important to prevent a serious illness.

Maxillary Sinusitis Symptoms

The maxillary sinuses are found under the eyes, in the cheekbones. It is the most common place for a sinus infection. The goal of relieving symptoms is to get the sinuses to drain. The most common symptoms are cheek pain and a feeling of pressure. Breasts usually contain air. When they become inflamed and inflamed, the increased pressure in the sinus cavity causes pain. Inflammation can make breathing through the nose difficult.

Other signs and symptoms of maxillary sinus infection include fever, redness and swelling around the eye and cheek area, and pain around the upper teeth. Your teeth may even be sensitive to chewing. Symptoms can occur on one side, or both, and it is relieved when lying down. Posterior nasal drip and cough are possible, as the sinus or sinuses drain into the back of the throat and cause irritation. There may be yellow or green nasal discharge. Fatigue, loss of smell and halitosis can also be indicative of a sinus infection.

When to seek help

Maxillary sinus infections can spread to other sinus cavities. A split headache, tearing, swelling around the eyes and redness of the skin around the eyes (periorbital cellulitis), fever, chills and vision changes can mean that a sinus infection is spreading. The treatment of a doctor should not be delayed. Swelling around the eye is severe and can quickly lead to blindness.

Causes of sinus pain under the eyes

Sinus pain under the cheekbone usually indicates a larger nasal sinus abnormality, called the maxillary sinus. That sinus is directly under the cheekbone and covers the area from just above the upper teeth to just below the eye socket, according to the book “Head and Neck Surgery-Otolaryngology” by Byron Bailey. The ethmoid sinuses are located deeper and closer to the nose, but can also cause pain under the cheekbone. The pain in that area may also be due to migraines, dental infections and facial traumas.

Acute sinusitis

Acute sinusitis, also known as acute rhinosinusitis, is a sinus infection that lasts less than two months. Infections that cause sinus inflammation can cause sinus pain under the cheekbone, according to The pain may be due to inflammation or pressure in the sinuses due to the accumulation of fluid during an acute infection.

Chronic sinusitis

Chronic sinusitis refers to a sinus infection that lasts more than two months or keeps coming back. According to, chronic sinusitis causes swelling around the openings of the paranasal sinuses, which causes the accumulation of mucus inside the sinuses. The constant pressure of mucus accumulation leads to a dull ache under the cheekbones. Other symptoms may include nasal congestion, decreased sense of smell, watery eyes and swelling around the face and eyes

Nasal polyp

Nasal polyps are polyps filled with pus that grow inside the sinuses. Polyps often result from chronic sinusitis. According to the book “Pathological basis of the disease” by Ramzi Cotran, polyps do not cause any symptoms at first, but when they get bigger they begin to push the bone and block the sinuses. Once they reach that point, they cause pain similar to chronic sinusitis. Otolaryngology specialists often have to perform surgery to get rid of polyps.


Tumors of the nose and sinuses, whether benign or malignant, can cause sinus pain under the cheekbones. The reasons why they are similar to those of nasal polyps. In addition to pain, sinus tumors often cause other symptoms such as bleeding, nasal obstruction, decreased smell and changes in vision.
