Summary
Objective: To investigate the frequency of airway injury and damage to other vital structures
associated with cervical bite wounds in dogs and cats and the implications for management
and outcome.
Methods: A retrospective search of electronic patient records was used to identify dogs and
cats suffering cervical bite wounds that were presented to a large multidisciplinary
veterinary hospital over a four year period.
Results: Complete records were available for 55 animals, with one animal suffering two separate
injuries. Fourteen animals (25%) had injuries to vital structures, including airway
injury in nine (17%) which was surgically confirmed and treated in six (11%). Airway
injuries were associated with either subcutaneous or mediastinal emphysema in all
affected animals. Other structures injured included the jugular vein, pharynx, oesophagus
and spine. Airway injuries were treated with primary repair in five animals and a
fasciomuscular patch in one. Temporary tracheostomy was performed in three animals.
Median duration of hospitalisation was one day (0-19) with 53 animals (54 cases) (96%)
surviving to discharge. Long-term follow-up (16-114 months) revealed that 43 of 49
animals were alive with six that died due to unrelated reasons.
Clinical significance: Cervical bite wounds are associated with significant injury to vital structures.
Up to 17% of animals may have injury to their airway. Identification and treatment
of airway injury is vital and was associated with an excellent outcome in six animals.
