Ginestet introduced the first external device used to fix the mandible in 1936. In 1949, Morris introduced a biphasic fixation device. This “Joe Hall Morris fixation” design led to use of a self-crafted external fixator based on pins connected by a breathing tube filled with dental resin. The objective of this study was to present our surgical results with this device through a 65-patient series.
This retrospective study included all the patients who benefited from the self-crafted mandibular external fixator at our Oral and Maxillofacial department from 1995 to 2019. Sixty-five patients were allocated into two groups. There were 39 patients in the temporary stabilisation (TS) group and 26 in the bone healing (BH) group. Functional criteria were investigated, including mouth opening limitations and occlusal abnormalities. Aesthetic evaluation focused on skin healing, evaluated by both surgeon and patient.
Twenty-three patients exhibited spontaneous bone healing during their immobilisation period and two patients developed a pseudoarthrosis in the BH group. Most TS group patients benefited from secondary management by bone graft, bone free flap, or distraction osteogenesis. Few complications were noted with our technique during the study period.
Our self-crafted external fixation with Joe Hall Morris fixation style is a valuable option for external stabilisation of the lower third of the face.Le texte complet de cet article est disponible en PDF.
