Classification proposal for fractures of the processus condylaris mandibulae

Abstract

Objective The current classification of mandibular condyle fractures as basal, low neck, and high neck as reported by Loukota et al. (Br J Oral Maxillofac Surg 43:72-73, 2005) and Neff et al. (Craniomaxillofac Trauma Reconstr 7:S44-S58, 2014) has a weakness. Nearly no high-neck fractures are reported (they are typically classified as type C head fractures) contrary to basal condylar fractures, which are overestimated (nearly all low-neck fractures are classified as basal). The aim of this study is to present a modified AO/SORG classification of mandibular condyle fractures. Material and methods A new arrangement of the reference lines is proposed because the fracture lines are mainly oblique in this region. The proposed classification was validated using a series of 84 cases that were treated surgically. Results The diagnoses using the proposed new classification system significantly differed from those based on the old system (p < 0.005). All basal fractures in the new classification system were also classified as basal in the old system. The same was true for type C head fractures. The differences were found for low-neck fractures (4 of 84 diagnoses differed between the old and new classifications, i.e., they were previously classified as basal fractures) and high-neck fractures (3 of 84 fractures were diagnosed as low-neck fractures or type C head fractures using the old classification). Conclusion The epidemiology of the condyle injury should be based on a classification, which reveals types of fractures which are represented by factually and frequently observed cases. That is why a relatively common AO/SORG classification can be modified for the benefit of assessing incidences of high-neck and low-neck fractures. Clinical relevance Considering that the treatment of the high-neck fractures is much technically complicated than the low-neck ones, this will have an influence on the management of trauma to the area.

“…The condylar process was cut in level of typical head-neck condylar fracture in each model according to the newest classification. [31] Proximal head and distal ramus fracture segment were fixed by plate and the same 6-mm length self-tapping screws of 2.0 system. In each of 7 mandibles for plate design, drill 1.5 mm in width was used before filling plate holes by screws.…”

“…An ideal classification should take anatomical aspects of fracture and also should be clinically useful and support surgeon in making adequate decision about treatment method. During ages many various classifications have been described [25,26,27,28,29,30,31,32,33,34]. Different classification systems of CFs proposed by many authors used conservative treatment involves passive (painkillers, soft diet, functional therapy) or active procedures (flexible tractions, braces, functional therapy) [35,36,37].…”

“…Despite the fact that there is a great number of classification systems of CFs none of them become a gold standard. This topic is still discussed and authors did not desist to seek out a decisive consensus [33,34].…”

Comparison of compression screws used for mandible head fracture treatment—experimental study

“…Surgical management of mandibular head fractures has rapidly progressed in recent years, thanks to improvement in diagnostics [1], including accurate classification and imaging by cone beam tomography, as well as advances in surgical procedures and the development of new surgical materials. On one hand, the treatment principles are constant: reduction and fixation.…”
