Objective:
To describe complications and long-term outcome after surgical correction of severe overbite in 7 horses using corrective osteotomy and a Type I external fixator.
Study Design:
Case series.
Animals:
Horses (n = 7).
Methods:
Seven horses with severe mandibular brachygnathia were treated by corrective osteotomy and a Type I external fixator. Data on surgical technique, complications, long-term outcome and owner satisfaction were recorded.
Results:
Severe mandibular brachygnathia was corrected successfully in all horses. Short term follow-up revealed a relatively high morbidity due to several complications such as surgical site infection, sequestrum formation and instability due to early pin loosening. Long-term over all owner satisfaction was very high.
Conclusions:
Corrective osteotomy and fixation with an external fixator is an effective surgical technique for correction of severe mandibular brachygnathia and offers good results in a long-term perspective.
