    What is sinusitis?Sinus diagram

    Your sinuses are air-filled chambers within the bones of the face. There are four pairs of sinuses: the frontal, ethmoid, maxillary and sphenoid sinuses, forming an irregular, honeycomb structure. When they are working well, the sinuses constantly circulate air and produce/drain mucous which lubricates your nose and helps keep it clean. This drainage system can shut down when an underlying problem, such as colds, allergies or an obstruction causes blockages, resulting in nasal congestion, headache, pain and pressure around the face, lethargy, low-grade fevers, post-nasal discharge and post-nasal drip. During infections or allergy flare-ups, the cilia (tiny hair-like structures) can stop working and contribute to the build-up of fluid within the sinus cavities. This stagnant fluid is the perfect breeding ground for bacteria, fungus and viruses. Chronic sinusitis is the main disease in which the center specializes.

    Advanced sinus care

    At the Loma Linda Sinus Center, our doctors have the highest level of training available in diseases of the nose and sinuses. We use the most modern and best tools in the diagnosis and management of our patients. This includes regular use of diagnostic nasal endoscopy and multiplanar CT scans.

    Culture-directed therapy

    We believe that the best method to treat patients with sinus infections is to obtain endoscopically guided cultures. Using cultures may result in more effective treatment or protect you from side effects when no antibiotic is required.

    Sinus nebulization therapy

    Doctors at the Center have been involved in research on this exciting new way to treat sinus infections. Sinus nebulization allows medications to be delivered directly to the surface of the nose and sinuses.

    Computer assisted surgery

    Your surgeon may also suggest that your surgery include surgical navigation. This involves a special type of CT scan, which is used during the surgery to decrease complications and improve results.

    Sinus surgery

    Most cases of sinus-related diseases can be treated with medicines. However, in some cases surgery may also be needed. Newer less deforming and less painful surgeries are now used. The most common type of surgery is called Functional Endoscopic Sinus Surgery (FESS).

    During FESS, your surgeon will use small cameras and instruments to carefully work in the nose. This is similar to the equipment used in the office to examine your nose. The obstructing tissues will be removed to allow the sinuses to drain more naturally. This should decrease the severity, frequency and duration of the infections.

    If surgery is recommended, the doctors at the Center will clearly explain the procedure, benefits, risks, post-op care and answer all your questions.

    CoupleBefore your visit

    You may need a referral from your primary care provider. The staff at the Center will provide you with information required to preauthorize your visit and any diagnostic studies that may be needed. The staff will also provide you or your insurance provider with necessary codes and procedure information.

    We suggest that you bring copies of your previous medical records and X-ray films to your visit. You should also make a list of your questions to be reviewed together with your surgeon.

    Expect to spend at least 45 minutes during your first visit and allow time for diagnostic studies, which may be necessary also. The doctors at the Center do not rush during the care of their patients and may be involved with teaching others during your visit.

    If you are being referred for surgery, we may be able to pre-schedule your clinic and surgery dates in advance - especially if you are traveling far for your visit.
