Prevalence is low in comparison to the more common paranasal malignancies in the maxillary or nasal sinuses. As in all cancers, early detection improves rates of survival. If ethmoid cancer remains localized, 82 out of people are still alive beyond five years. However, if ethmoid cancer has metastasized, or spread to other parts of the body, only 43 to 52 out of people will surpass five years of survival.
If you suffer trauma to the face and have symptoms of NOE fracture, you should seek medical attention immediately. Rapid diagnosis of NOE fracture with a thorough exam to determine if surgery is required is important to optimal recovery.
Most sinusitis is caused by a virus, so antibiotics will generally not be recommended. If you are immunocompromised, your risk will be higher for having either a bacterial or a fungal sinus infection. If your healthcare provider is concerned that polyps are the underlying cause of your symptoms, a computed tomography CT scan will likely be ordered. Your healthcare provider may also use a fiber optic scope to visualize inside your nose and sinus cavities.
Treatment of polyps in the ethmoid sinuses or correction of deviated septums can be performed surgically. Members of your interdisciplinary team may include:.
For this surgery, you can anticipate a small incision on the upper side of your nose near your upper eyelid. By removing a small part of the bone that is part of your orbital bones, your surgeon will be able to remove the tumor. If the tumor has spread into the ethmoid sinus cavity, the base of the skull, or to the brain, your surgical team will involve both an otolaryngologist and a neurosurgeon due to the ethmoid's crista galli anchoring tissue that surrounds the brain as well as the risk for neurological issues if complications occur.
This surgery is referred to as craniofacial resection. Sign up for our Health Tip of the Day newsletter, and receive daily tips that will help you live your healthiest life. Bell DJ, Jones J.
