Abstract
BackgroundMany novel approaches to mandibular condyle fracture have been reported, but there is a relative lack of reports on the Risdon approach. In this study, the feasibility of the Risdon approach for condylar neck and subcondylar fractures of the mandible is demonstrated.MethodsA review of patients with mandibular condylar neck and subcondylar fractures was performed from March 2008 to June 2012. A total of 25 patients, 19 males and 6 females, had 14 condylar neck fractures and 11 subcondylar fractures.ResultsAll of the cases were reduced using the Risdon approach. For subcondylar fractures, reduction and fixation with plates was done under direct vision. For condylar neck fractures, reduction and fixation was done with the aid of a trochar in adults and a percutaneous threaded Kirschner wire in children. There were no malunions or nonunions revealed in follow-up care. Mild transient neuropraxia of the marginal mandibular nerve was seen in 4 patients, which was resolved within 1–2 months.ConclusionsThe Risdon approach is a technique for reducing the condylar neck and subcondylar fractures that is easy to perform and easy to learn. Its value in the reduction of mandibular condyle fractures should be emphasized.
Highlights
Many novel approaches to mandibular condyle fracture have been reported, but there is a relative lack of reports on the Risdon approach
Intraoral reduction is generally accepted for symphyseal and parasymphyseal fractures, there is still some debate regarding the use of the intraoral approach to condylar neck and subcondylar fractures because of the surgical skills and associated hardware required [5]
In all of the subcondylar fractures, open reduction and rigid fixation were completed under direct vision
Summary
Many novel approaches to mandibular condyle fracture have been reported, but there is a relative lack of reports on the Risdon approach. The controversy has regarded closed conservative management versus open surgical management of condylar and subcondylar fractures, which constitute 25-35% of all mandible fractures reported in the literature [2]. Those who prefer conservative treatment argue that morbidity due to surgical treatment is much greater than the advantages gained, and that 3–4 weeks of intermaxillary fixation and early mouth opening exercises are enough to achieve good results. The aim of this study was to determine the efficacy and safety of surgical treatment of condylar fractures using the Risdon approach, as well as to describe our clinical experience
