[Late outcome and complications of mandibular compression osteosynthesis with intraoral approach--a 10-year study]

Late results and complications following rigid internal fixation of mandibular fractures-a 10 year survey. From 1984 to 1993 541 fractures of the mandible in 332 patients have been treated by rigid internal fixation with the mandibular compression system (MCS). In 0.8% we saw serious complications like pseudarthrosis or osteomyelitis. In a retrospective study 105 patients with 171 fractures of the mandible could be examined 4.1 years after osteosynthesis. In case of preoperative normesthesia of the inferior alveolar nerve in 74.1% of the fractures nomesthesia was still present, 18.1% of the fractures showed hypesthesia and 4.2% showed complete anesthesia. In case of already preoperatively existent hypesthesia in 81.8% of the fractures normesthesia and in 8.2% hyp- or paresthesia were seen. There were no anesthesias seen in this group. 3.6% of the fractures showed mild occlusal disharmonies.
