A Retrospective Study of 56 Dogs with Oronasal Fistulas Associated with Periodontal Disease

Abstract

A study of 56 dogs with oronasal fistulas revealed that a high proportion of the animals presented with nasal symptoms such as sneezing and nasal discharge. The maxillary canines were most frequently affected. The average age of onset for oronasal fistula was higher than that for severe periodontitis in a group of 100 dogs with severe periodontitis. Miniature dachshunds exhibited a greater predilection for oronasal fistula than severe periodontitis. Dogs treated with extraction of the affected teeth, flap elevation, and fistula closure showed a favorable outcome, while most cases treated with the aim of preserving the affected teeth experienced recurrence.
