These words are commonly uttered by patient's presenting to our
ear nose and throat office. While I understand where they're coming from, the
patient may have a wide variety of problems that we label
"sinusitis."
A better way to think of it, and then this will help one
understand treatment options, is to divide it up into two categories ---
sinusitis and rhinitis.
The term sinusitis applies to inflammation or infection in the paranasal
sinus cavities that surround the nose. There are frontal, ethmoid, maxillary,
and sphenoid sinuses. These sinuses can be involved in disease processes
individually or multiple sinuses.
Rhinitis is the term for inflammation of the nose. When the
patient has rhinitis they may or may not have sinusitis. Usually, however, when
patients have sinusitis they do have some component of rhinitis or nasal
inflammation.
Understanding the purpose of the nose and sinuses helps us to
understand disease processes as well as their treatment. The nose is primarily
responsible for filtering out infections and irritants such as dust as well as
the very important function of humidifying the air we breathe into our lungs.
The nose produces approximately 1.5 Liters of fluid in order to accomplish this
per day. Also, whether you're in 0°cold or 110° heat, by the time the inspired
air enters the lung it is body temperature, quite an amazing feat!
Symptoms of rhinitis include excessive drainage or post nasal
drip, congestion, facial pain pressure, and headaches. Symptoms of sinusitis
include the same. Therefore, by symptoms alone, it can be difficult to
distinguish between the two.
An important structure inside the nose to understand is the
turbinates. There are three turbinates on the lateral wall of the nose that
contain glandular tissue that produce most of the mucus that provides filtering
and humidification function. When the turbinates get inflamed, excessive mucus
is produced (i.e. drainage and post nasal drip) and they may swell giving you
congestion, facial pain and pressure.
Sinusitis is usually a consequence of an earlier form of rhinitis.
Examples of rhinitis include infectious rhinitis (the common cold), allergic
rhinitis, and chronic rhinitis from irritants such as smoking or chemicals.
Treatment of rhinitis focuses on the symptoms. Decongestants such
as Sudafed are used to treat the congestion which also causes the facial pain
and pressure. Antihistamines such as Allegra or Benadryl are used to treat the
excessive drainage. Other treatments include nasal steroid sprays such as
Flonase which reduce the inflammation in the turbinates thereby addressing both
the congestion and drainage problem. We also now have spray antihistamines,
such as Astepro, which address the drainage problem. Many medications are
packaged as an antihistamine combined with Sudafed for example Allegra-D. In
severe cases of rhinitis, short-term anti-inflammatory steroids may be used to
provide quick relief.
In the case of sinusitis, the natural drainage mechanism from the
sinus into the nose becomes inflamed or occluded and allows for infection from
the nose to then secondarily infected sinuses. Treatment of the sinusitis
therefore must also rectify the rhinitis problem as well as address the
infection with antibiotics. Saline rinses are also very helpful in the case of
rhinitis as well as sinusitis. They provide irrigation benefit to wash away
infection but also improve the hydration of the nose and saline is actually a
mild decongestant.
Treatment guidelines would be to treat rhinitis symptoms with
over-the-counter products and if the rhinitis continues for more than 5-7 days
then one is at higher risk of the rhinitis transitioning into a sinusitis.
Medical intervention with your doctor would be valuable at that point. If
rhinitis is occurring frequently or is prolonged then maintenance medications
such as the nasal steroid sprays are needed under the guidance of a medical
professional.
Sinusitis treatments are based on history and physical exam
findings and possibly X-rays. Occasional sinusitis can be treated based on
clinical symptoms whereas X-rays, to include CT scans, are utilized to evaluate
patients with prolonged or severe symptoms. And in some cases the sinusitis
simply cannot be cleared and drainage of the sinus needs to be performed in
order to recover. These procedures can be done utilizing endoscopes through the
nose to identify the sinus drainage systems and open them up and irrigate the
sinus. This has traditionally been done in an operating room setting however
recent technology advances, such as Balloon Sinuplasty, allow ear nose and
throat physicians to open and irrigate the sinuses in the office with topical
anesthesia.
So as you can see, when one says "Doc, I've got sinus" to
me that can mean many different problems requiring a wide variety of solutions.
And finally, for a bit of humor, here in Alabama some of my
patients pronounce sinusitis as "sign-Unitas" to which I have always
wanted to respond " Isn't that what the Colts did in '55..........?"
