The symptoms of malignant sinonasal tumors depend on where the tumor is and what type of tumor it is.
Below are symptoms that may arise in association with where the tumor is located:
- Nasal cavity: Symptoms may include a mucous discharge, crusting within the nose, nasal obstruction, and nosebleeds.
- Maxillary sinus: The maxillary sinus is just below the eye; therefore, swelling in the cheek or just under the eye may be present.
- Frontal sinus: The frontal sinus is above the eye; therefore, swelling on the forehead above the eye may occur. If the tumor is large enough, the eye may be pushed down and vision can be affected.
- Ethmoid sinuses: The ethmoid sinuses are between the eyes, and a tumor here may push into the nasal cavity, causing a blockage. It may also push into the eye, displacing it from the eye socket, and cause double vision.
Other symptoms that may appear as the tumor grows include:
- Blocked sinuses that do not clear, or sinus pressure
- Headaches or pain in the sinus areas
- A runny nose
- A lump or sore inside the nose that does not heal
- A lump on the face or roof of the mouth
- Numbness or tingling in the face
- Swelling or other trouble with the eyes, such as double vision or the eyes pointing in different directions
- Pain in the upper teeth, loose teeth, or dentures that no longer fit well
- Pain or pressure in the ear
Having one or more of these symptoms does not mean that you have a malignant sinonasal tumor. If you think you may have a malignant sinonasal tumor, call your doctor right away.
