Chronic sinusitis in dogs

Abstract

This paper reveals the results of clinical, laboratory and therapeutic investigations in a case offrontal chronic sinusitis in a dog. The patient was brought in for consultation with two well defined collections in the left supraorbital region, which led to exophthalmia and bilateral muco-bloody rhinorrhea. The superior nasal cavity wall was soft at palpation, and the inferior one was bulging into the oral cavity. The laboratory results excluded the parasitical (Linguatula serrata) or fungal etiology (Aspergillus spp.), the clinical signs (lack offever, presence of appetite and absence of dental disease) excluded the possibility of a septic inflammation. X-rays of the head and gross anatomy findings after maceration of the skull revealed serious lesions of the frontal, lacrimal, zygomatic, maxillary, ethmoid bones, offering a large communication with the cranial cavity, though the animal did not present any signs of postural and dynamic distress. All these advocate in favor of a neoplastic process involving the frontal sinus and the nasal cavity.
