Abstract

PURPOSE
The treatment of children mandibular condyle fracture that is severely displaced is controversial. The conservative treatment of it may lead to complications- mandibular deficiency, asymmetry, malocclusion and temporomandibular joint dysfunction. Moreover, open reduction carries risks for growth retardation, facial nerve injury, scarring and joint stiffness. The aim of this article is to present an alternative technique of the treatment by using a threaded Kirschner wire and external rubber traction.
METHODS
From November 2005 to May 2008, three patients underwent the management by using a threaded Kirschner wire and external rubber traction. A threaded Kirschner wire was inserted in the condylar segment by using a C-arm. We applied the external rubber traction, and we reducted the segment progressively until complete reduction. The mandibular-maxillary fixations were removed after 3 weeks, and patients were sent to training for mouth opening.
RESULTS
The technique didn't result in complications- joint dysfunction, facial nerve injury, sore, infection and nonunion during follow-up period. Radiologic follow-up examinations revealed correct reduction in all patients. In all cases, we found restoration of preinjury occlusion and temporomandibular joint function.
CONCLUSION
Closed reduction of children mandibular condyle fracture by using a threaded Kirschner wire and external rubber traction did achieve anatomic reduction and restore mandibular height. This alternative technique is simple, effective, inexpensive, easy to apply and minimally invasive.
