Maxillary sinus

Maxillary Sinus Symptoms:

There are many different types of maxillary sinuses. They include:

1) Maxillary sinus cavities (the main ones): These are the most common type of sinus cavities.

There are two kinds of maxillae, one located at the front and one located at the back. The maxilla consists of three bones: the mandible, the nasal septum and the maxillary bone.

2) Maxillary sinuses with a mass: A mass is a collection of fluid or tissue inside the sinus cavity.

Masses may be caused by infection, trauma or tumors. Masses can cause pain when they are squeezed or pushed against other parts of your body such as nose hairs.

Masses can lead to a variety of symptoms including:

a) Pain when squeezing or pushing against other parts of your body;

b) Soreness in the cheek area;

c) Swelling around the eyes; and/or

d) Difficulty breathing.

3) Maxillary sinuses without a mass: These are usually found in people over 40 years old.

They do not have any mass inside them. They tend to be small and do not cause any symptoms.

4) Other types of sinuses: The sphenoid, frontonasal, frontal, and ethmoid are the other types of sinuses that are less common than the maxillary ones.

The structure of the human body is complex and made up of many different parts. It is important to understand your anatomy in order to keep it healthy and functioning well.

The human body is composed of three types of tissue: epithelial, connective and muscle. There are four types of epithelial tissue: simple, stratified, pseudostratified and transitional. There are three types of connective tissue: dense regular, dense irregular and loose connective. There are two types of muscle tissue: skeletal and smooth. There are also two types of joints: fibrous and cartilaginous.

The teeth in your mouth have several parts. The crown is the most visible part.

It is the part of the tooth that is visible when you look at it. Surrounding the crown is the neck, which connects the crown to the root of the tooth. The root of the tooth is embedded in the jawbone and can be found on the inside of your mouth or under your gums.

The hard palate is a rigid board of tissue that divides your nasal cavities and the roof of your mouth. It is located between your two maxillary sinuses.

The nasal septum divides the left and right sides of your nose. It divides the inside of your nose into two cavities: the left and right nasal cavities.

These in turn are connected to your mouth by your Eustachian tubes, which run through your middle ear to connect them to your throat.

The frontal sinus is hidden behind your forehead. It is located between your forehead and your eyebrows.

The sphenoid sinuses are located towards the center and sides of your head behind your eyes. There are several of these hidden in a honeycomb like area between your eyes and cheekbones.

What remains now is to discuss the actual process of checking your sinuses. There are two main ways of doing this.

The first way, and most common, is to use a flashlight while looking into a mirror. The flashlight method can be difficult to use since it requires good lighting in the room you are in. The other method, and less popular, is using a long tube with a light on one end and a mirror on the other. This method is known as an endoscope.

The flashlight method:

1) Find a well lit room with a mirror.

2) Look in the mirror and hold the flashlight so the light is shining in one of your eyes.

3) While looking in the mirror, tip your head backwards so that the light from the flashlight is shining upwards into your nose.

4) Slowly move the flashlight from side to side until you can see light coming through at the top of your nose.

This means that light is shining into your left or right nostril and then reflecting off the back of your hard palate and into your corresponding maxillary sinus.

5) By moving the flashlight from side to side, you should now be able to see if any other sinuses are draining into your nose.

If the light gets brighter at any point, then you can presume that that sinus is draining into your nose.

6) If you see any other lights brighten up while shining the flashlight in the mirror, write them down along with which nostril they correspond to.

If this is confusing to you, refer back to the diagram you drew before of which sinuses drain into which nostrils.

The endoscope method:

1) While looking into a well lit room, have someone look into your mouth using a long skinny flashlight.

2) Shine the light upwards and have your assistant look for light coming through any part of your nasal passages or sinuses.

For example have them shine the light on the back of your soft palate and have them look for light in your maxillary sinuses.

3) If there is light showing, then that sinus is draining into your nose.

If this happens, have your assistant gently press on that area of your nose and see if any more light shows up from the front of your nose. If it does, then you can reasonably presume that your sinus is plugged up since it couldn’t drain out the top of your nose.

I will leave it to you to experiment and make a list of all the different ways that your sinuses are draining.

One more thing I should tell you about is what to do if this exercise irritates your nose. Many people complain of a runny nose or sometimes even a bloody nose while doing this exercise.

This is because you are pressing on the sides of your nose which can cause your sinuses to drain. While this can be a nuisance, it is also an important part of the exam since you need to know which sinuses are draining into your nose. If your nose starts running, I would recommend using a tissue or handkerchief while doing the rest of the exam. If it continues to run excessively, you may want to hold off on doing the remaining parts of this exam until it stops.

Time to do some more exploring!

This time you will be shining the flashlight into your ears and looking for light reflections off of your eardrum.

To do this part of the exam you will need to find a very well lit room or one with bright lights. This is because you are going to need a lot of light to see into your ear canal.

If you are in a dark room then the light won’t be bright enough to give you a good view into your ear. Finally you will need someone to help you since you can’t see into an ear by yourself.

With the help of your assistant, locate your ear canal by feeling around the top and side of your ear. When you find it, use a mirror or have your assistant look in your ear to make sure that you are only looking into the ear canal and are not seeing any of the inside of the outer ear (pinna).

Start shining the flashlight into your ear while your assistant watches the ear canal for any light reflections. If you see or hear any light reflections then your eardrum is intact and has no air or fluid behind it. This means you pass this portion of the test.
