“…Otherwise, in a soft‐tissue window, bone and mucosa will appear as a homogeneous iso‐attenuating area, whereas the real thickness of each structure will be masked. CT is superior for imaging the equine skull to gain contiguous transverse images that allow proper three‐dimensional (3‐D) orientation and extension, location, and size of pathologies 9–16 …”

Heads from 15 male and female horses of various breeds and ages were examined with computed tomography under general anesthesia in dorsal recumbency. The main interest was the evaluation of the entire paranasal sinus system. Special attention was paid to the location, size, and shape of the conchomaxillary, nasomaxillary, frontomaxillary, and sphenopalatinal openings. The frontomaxillary opening was the largest aperture and was found to be age-dependent in size mostly. Orientation and shape of the openings were sagittal or horizontal; the narrowest of them was the slit-like nasomaxillary aperture. The thickness of the vascularized mucous membranes in the nasal cavity was obtained up to 6 mm; the surface was smooth and well defined. The paranasal lining was invisible in computed tomography (CT) images because of its thin layer. CT proved to be a very useful method for documentation of the paranasal openings and for evaluation of the state of the mucous membranes in the nasal and paranasal cavities.

SUMMARY A 4 month old foal with right sided maxillary enlargement and considerable upper airway obstruction had an ameloblastic odontoma in the right maxillary sinus. This odontogenic tumour, probably congenital in nature, had extensively distorted the structure and contours of the sinus, and displaced the adjacent turbinates and nasal septum. RÉSUMÉ Un foal de 4 mois présentait une hypertrophie du maxillaire supérieur droit avec obstruction marquée des voies respiratoires supérieures: ceci était provoqué par un odontome ameloblastique dans le sinus maxillaire droit. Cette tumeur odontogène de nature probablement congénitale avait déformé considérablement la structure et l'aspect du sinus et déplacé les cornets et le septum voisin. ZUSAMMENFASSUNG Ein vier Monate altes Fohlen mit einer rechtsseitigen Umfangsvermehrung der Maxilla und erheblicher Atem‐wegsstenose wies ein ameloblastisches Odontom in der rechten Kieferhöhle auf. Dieser odontogene Tumor, der wahrscheinlich bei der Geburt vorhanden war, hatte die Struktur und die Umrisse des Sinus hochgradig verzerrt und die angrenzenden Conchen und das Nasen‐septum verdrängt.

“…No controlled prospective studies can be found describing well-established surgical strategies for primary maxillary sinus neoplasms in the literature. Suggestions for therapeutic intervention can only be found in small case series and anecdotal case reports and vary from surgical resection, curettage, radiotherapy, cryotherapy to local chemotherapy (Leyland and Baker 1975;Boulton 1985;Walker et al 1998;Dixon and Head 1999;Perkins et al 2009;Ahern et al 2010;Hawkins 2010). To date, standard treatment protocols have failed to produce favourable outcomes in horses with SCC of paranasal sinuses.…”

Summary This case report describes the history, clinical findings, diagnostic imaging (including computed tomography), gross pathology and histopathology of 2 cases of squamous cell carcinoma in the paranasal sinuses. Radiography of the skull is a useful tool to detect a mass in the paranasal sinuses, but the position, extent and character of the lesion can be better visualised with computed tomography.
