Abstract

The goal of the present study was estimate the capability of the ultrasonography (US) for
following up the simple, transverse and non-complicated mandibular fracture healing in dogs. nine dogs
aged from 2-3 years and weighted from 15 to 20 kg were used. Mandibular fracture was induced
experimentally and the fractured parts were fixed by Dynamic Compression Plate (DCP) and bone
screws. Fracture healing was arbitrated by using ultrasonography. The results showed that, the fracture
line was appeared ultrasonographically as an-echoic to hypo-echoic area neighboring to the hyperechoic
bone and the bone plate was appeared hyper-echoic after fixation. During chase the fracture
healing of the mandible by using US, there were changes appeared in the echogenicity at the site of
fracture. In conclusion, the Ultrasonography could be utilized to assess the stages of mandibular fracture
healing in dogs.
