Case ReportsDistraction osteogenesis for reconstruction after mandibular segmental resection.
Distraction osteogenesis with the shortening and lengthening method is a well-established procedure for repairing extremities. We used this technique for reconstruction after mandibular segmental resection. A 74-year-old woman underwent distraction osteogenesis with an intraoral device, initially shortening the mandible after a 20-mm-long segmental resection, followed by lengthening at a rate of 0.8 mm per day for 21 days. ⋯ Radiographic observation showed new bone formation, and the implant was completely osseointegrated. Although the follow-up period is relatively short, the clinical course was uneventful. Distraction osteogenesis with the shortening and lengthening method seems to be a feasible option for reconstruction after segmental resection of the mandible.

The biological concept of "internal derangement and osteoarthrosis": a diagnostic approach in patients with temporomandibular joint pain?
We sought to investigate whether the finding of temporomandibular joint (TMJ)-related pain may be linked to magnetic resonance (MR) imaging findings of TMJ internal derangement and TMJ osteoarthrosis. ⋯ The results suggest that TMJ-related pain is correlated with TMJ-related MR imaging diagnoses of internal derangement and osteoarthrosis. The data confirm the biological concept of "internal derangement and osteoarthrosis," yet re-emphasize that internal derangement and osteoarthrosis may not be regarded as the unique and dominant factors in the definition of TMJ pain.
