Background: Mandibular condylar fractures are common,
with prevalence between 25% and 35% of all mandibular
fractures. In children, the condylar fractures are usually
managed with maxilla-mandibular fixation, where as in adults
the treatment of condylar fractures remains controversial.
Several investigators validated the use of Botulinium Toxin
(BTX) for treatment of recurrent temporomandibular joint
dislocation. However, there are very limited studies that
assessed (BTX) injection in the management of condylar/
subcondylar fractures.
Patients and Methods: Ten patients presenting with condylar/
subcondylar fractures either isolated or associated with
other mandibular fracture were treated by Ultrasound guided
(BTX) injection to Lateral Pterygoid Muscle (LPM) followed
by application of arch bar and guiding elastics 2-3 days later.
Results: Patients retained good occlusion with unrestricted
mouth opening. Minor deviation upon mouth opening was
observed in some of the cases. Good alignment of the condylar
/subcondylar fracture was documented radiologically over a
minimum of three-month follow-up period.
Conclusion: The use of botulinium toxin in condylar
fractures is safe, and can be used as nonsurgical adjuvant in
management of condylar/subcondylar fractures
