Some Observations on Chronic Nasal Disorders in the Dog

Abstract

A retrospective study of sixty cases of canine nasal neoplasia seen at The University of Glasgow Veterinary School between 1983 and 1985 reached the following conclusions: There was no breed predilection; medium to large mesaticephalic dogs were the most commonly affected; the mean age was 9. 2 years; there was no sex predisposition; a wide variety of clinical signs was observed, no single one being pathognomonic; carcinomas were more frequent than sarcomas, adenocarcinomas being the most common. The radiographic features of nasal neoplasia seen on the dorso-ventral intra-oral view were - increased radiopacity together with turbinate destruction although six out of sixty cases did not follow this pattern; vomer erosion and septal deviation were highly suggestive of neoplasia; mineralisation was also indicative of neoplasia but was not typical of any one tumour type. These findings were related to the literature reviewed. A prospective study of twenty clinical cases of chronic nasal disorders in the dog seen between October 1985 and May 1986 concluded the following:- Radiography was the single most useful aid to diagnosis; rhinography provided little additional information; endoscopic examination was useful predominantly in destructive rhinitis and intra-nasal foreign bodies, an alternative to an endoscope would be a large bore auroscope. None of the biopsy techniques utilized were 100% reliable; treatment of aspergillosis with topical enilconazoie achieved good results
