|
|
|
What are the charateristics of an osteoma
|
Intense well-demarcated mineral opacity and is usually midline in rostral mandible.
|
|
|
Adamantinomas (epidermoid cysts) results in
|

|
|
|

|
What are the findings of an apical tooth root abscess?
|
indistinct margins of the lamina dura,
loss of the normal outline of the tooth root, blunting of the tooth root, widening of the periodontal membrane lytic tract extending out of the ventral cortex of the mandible. |
|
|
The most common diseases of the nasal cavity and paranasal sinuses are
|
fractures
pirmary sinusitis, sinusitis from dental disease, dentigerous cysts, maxillary sinus cyts, ethmoid hematomoas, and neoplasia |
|
|
When evaluating sinus fractures be sure to...
|
look for sequestrum due to loss of blood supply and
infection of the bone fragment. |
|
|
Sinusitis in horses is characterized by
|
the accumulation of fluid in one of the many nasal sinuses.
|
|
|
How can sinusitis be caused by teeth
|
Caudal maxillary teeth are surrounded by the rostral and caudal maxillary sinuses.
|
|
|

|
a tooth near the region of the external acoustic meatus.
usually with a draining tract. |
|
|

|
Maxillary sinus cysts
progressive ethmoid hematomas |
|
|
Maxillary sinus cysts occur
|
rostral to the ethmoid turbinates and are in young horses less than 1 year
|
|
|
Ethmoid hematomas occur in what age horses
|
over 7
thoroughbred and arabians. |
|
|
Ethmoid hematomas usually occur
|
in the ethmoid region, but can be in the frontal, maxillary and sphenopalatine sinuses.
|
|
|
What is the goal of gutteral pouch radiography?
|
identify soft tissue opacity in the gas-filled structure.

|
masses of the parotid gland
masses of the retrophhrypngeal lymph nodes, primary tumor of the guttural pouch - usually SCC. |

|
Dorsal displacement of the soft palate,
aryepiglottic fold entrapment subepiglottic cyst arytenoiditis, |
|
|
How does aryepiglottic fold entrapment appear?
|
the rostral aspect of the epiglottix is blunted.
|
|
|
If the epiglottis is displaced dorsally it is usually caused by
|
subepiglottic cysts
|
