Several cases of maxillary and mandibular fractures occurred over the
years in small cetaceans maintained under human care. These types of fractures have been
reported in wild dolphins and were observed both at strandings as well as in wild healthy
animals. In captivity these cases often occur during interaction between individuals.
The practical experience of several veterinarians shows a broad range of
therapeutic methodologies. The methods range from surgical approaches utilizing pins to maintain
apposition and alignment to the less invasive use of splints and the application of various
types casts or bandages.
This paper will review 17 clinical cases of jaw fractures (15 Tursiops
truncatus, 1 Stenella attenuata and 1 Lagenorhyncus obliquidens) exploring the
methods of surgical fixation, bandaging techniques, husbandry management of the animal for
feeding control, prognosis and results.
