2. Fundamentally situated in the skull, human sinus cavities are
the passageways mainly found in the areas around the face.
Also known as paranasal sinuses, they are hollow, irregular
air cavities which sit adjacent to and are attached to the nose
and nasal passageways.
Protection and lowering of the weight of the skull are the
principal tasks of these cavities and the human voice also
resonates here.
Both ENTs and dentists should thoroughly know the anatomy
of sinus cavities to properly handle the infection that
frequently spreads here.
Infection in the frontal or ethmoid sinuses can lead to
meningitis.
Images of the facial sinus cavities present its basic anatomy,
which includes four pairs of sinuses specifically...
• Frontal sinuses = Found between the outer and inner
tables of the frontal bone
• Maxillary sinuses = An empty cavity that occupies a
huge part of the maxilla
• Ethmoid sinuses = Which fills up a big part of the
ethmoidal labyrinth behind the eyes
• Sphenoid sinuses = Found in the sphenoid bone, but
which may stretch to the wings of the sphenoid, the
pterygoid plates and the clinoid processes
When determining x-rays, CT scans or MRIs of sinus
conditions, as well as infection, sinus cavities diagram are
very helpful.

3. For dentists, understanding the maxillary sinus is essential
since the apices of the teeth extends into the maxillary
cavity.
Removal of wisdom teeth (or "wisdome teeth" as it is
frequently misspelled) and root canal specifically of the first
molar may result in the progression of apical abscess or
periodontal disease, which may bring about acute maxillary
sinusitis.
The symptoms of a sinus infection will vary, relying on the
sinus cavity affected and the type of infection.
Acute sinusitis
Ethmoid sinusitis
• Nasal clogging with mucopurulent discharge
• Post nasal drip, together with a sore throat
• Soreness or strain around the inner corner of the eye or
down one side of the nose
• Headache in the temple, or around and behind the eye
• Soreness or stress symptoms become more intense
when coughing, forcing, or lying on the back, but improves
when the head is vertical
• Fever
Maxillary sinusitis
• Pain around the cheekbone, around or below the eye, or
surrounding the upper teeth
• Pain or pressure on one side or both sides of the face
• Tender, red, or swollen cheekbone

4. • Soreness and stress symptoms deteriorate with the head
in vertical position and bending forward, but improves when
lying down
• Nasal discharge or postnasal drip (may be accompanied
by sore throat)
• Fever
Frontal sinusitis
• Severe headaches in the forehead
• Fever
• Discomfort worsens while lying down but improves when
the head is vertical
• Nasal discharge or postnasal drip (maybe coupled with
sore throat)
Sphenoid sinusitis
• Deep throbbing headache with pain centred on the top
and the back of the head, the whole forehead, and behind
the eye
• Fever
• Pain worsens when lying on the back or bending forward
• Double vision or vision disruptions may develop if strain
runs into the brain
• Nasal discharge or postnasal drip (may be accompanied
by sore throat)
Chronic sinusitis
Ethmoid sinusitis
• Chronic mucopurulent nasal discharge, blockage, and

5. low-grade soreness especially over the bridge of the nose
• Discomfort gets worse late in the morning or when using
eyeglasses
• Chronic sore throat
• Chronic bad breath
Maxillary sinusitis
• Pain or stress under the eye
• Chronic toothache or heightened sensitivity in the tooth
• Pain increases with colds, flu, or allergies
• There is tremendous soreness all through the day
• Greater rounds of coughing at night
Frontal sinusitis
• Unrelenting, low-grade headache in the forehead
• Background of trauma or damage to the sinus area
• Chronic postnasal drip (may be accompanied by sore
throat and bad breath)
Sphenoid sinusitis
• Low-grade general headache
• Chronic postnasal drip (may be together with sore throat
and bad breath)
It will be simpler to find the infection and reduce its
propagation to the other parts of the head when a doctor
wholly understands the anatomy of the sinus cavities.
