paranasal sinus cysts
occur in horses primarily in the caudal maxillaary sinus and occasionally in the frontal or rostral sinus. Very young or old horses are affected. They present with nasal respiratory obstruction, facial swelling and nasal discharge. An increase in intramaxillary sinus pressure results in displacement of the nasal septum in a significant proportion of cases.
paranasal sinus polyps
rare cause of nasal bleeding in horses.

Paranasal sinus computerized tomography (CT) revealed a hypodense mass lesion that filled both frontal sinuses and right ethmoidal cells, caused erosion in the bone structures, and drooped into the right orbital extraconal area eroding the right lamina papricea (Figure 1).
Although paranasal sinus osteomas are frequently seen in the ethmoid complex, the aerated middle turbinate as a part of the ethmoid is an exceptionally rare site of origin of this tumor, and only one similar case has been previously reported (7).

Sinusitis is defined as an inflammatory process involving the mucus membrane of the paranasal sinuses and/or the bone.
Paranasal mucoceles are most commonly found in the frontal sinus, and are occasionally found in the ethmoid and sphenoid sinuses.
