ENTs are otolaryngologists, doctors with specialized training to treat the ear, nose and throat. These areas might not seem like a large part of your body, but health concerns with these areas cause more than half of the health concerns that send people to the doctor’s office in the first place. Seeing an ENT often gets you to a diagnosis and treatment faster.

If you are experiencing chronic problems with your ears, nose or throat it is time to schedule a visit. If your allergies, runny nose, sinus headaches, sleep or balance issues are not responding to treatment by your primary care physician then it is time to schedule a visit. If you are having problems staying awake during the day and snoring wakes others at night then it is time to schedule a visit.

Sinusitis is an inflammation of the sinuses, which may be due to infection. Sinusitis can be acute or chronic. Patients usually feel a combination of pain, pressure or headache. Sinus surgery is often necessary when sinusitis does not get better with medication or other treatments.

Our office provides many types of treatment, including surgery, which is often a final recommendation when other options are not effective. In addition to being skilled diagnosticians and clinicians, ENTs are required to undergo surgical training. So, if you need a surgical procedure, the ENT you see in the office will be the surgeon you have in the operating room. Most ENT surgery is outpatient or day surgery, meaning you return home the same day as your surgery.
