Question 1
What is space A?•Ethmoidal conchae•Cornual Diverticulum•Frontal Sinus
What is space B?•Gutteral Pouch•Nasopharynx•Spheno-palatine sinus
A
B
Incorrect
• No, this is not the Ethmoidal Conchae!
• Here are the Ethmoidal Conchae
• Try again!
Incorrect • No, this is not the Cornual Diverticulum!• This is only found in horned animals where there is a sinus
extending into the horns.• Here is the Cornual Diverticulum in a cow:
• Try again!
Correct!
• Yes! This is the Frontal Sinus!
• Here are some more examples.
• Try part B
Incorrect
• No, this is not the Nasopharynx!
• Here is the Nasopharynx
• Try again!
Incorrect
• No, this is not the Spheno-palatine Sinus. This is a small, irregular sinus not seen on radiographs.
• Try again!
Correct!
• Yes! This is the Gutteral Pouch!
• Here are some more examples.
• Try Question 2
Question 2
This is a lateral view of a horse’s cheek teeth. The arrows point to space above the roots of the teeth; what is this space?•Nasopharynx•Ventral Conchal Sinus•Maxillary Sinus
Why is this space important in the horse? What other important structure is present here?
Incorrect
• No, this is not the Nasopharynx!
• It is located much more caudally
• Here is the Nasopharynx
• Try again!
Incorrect
• No, this is not the Ventral Conchal Sinus. It does not communicate directly with the roots of the teeth.
• Try again!
Correct! • This is the Maxillary Sinus. It is important in the
horse as the roots of the cheek teeth are embedded here, so serious dental disease can present signs of respiratory tract infection. Entering the Maxillary Sinus surgically can be used as a route for accessing the roots of the teeth.
• Care must be taken when performing this procedure as the Infraorbital Nerve runs through the sinus and is vulnerable to damage.
