| Outline of Final Research Achievements |
Masticatory muscle tendon-aponeurosis hyperplasia (MMTAH) is a new disease entity associated with limited mouth opening. In this study, we analyzed the microstructural characteristics of muscles and tendons in MMTAH by electron microscopy and energy dispersive X-ray analysis to determine the elemental composition. Histological analysis was performed to detect the calcification. Transmission electron microscopy and scanning electron microscopy were conducted to clarify the microstructural characteristics of muscles and tendons. Energy dispersive X-ray microanalysis was performed to identify the distribution of elements. Mineralized nodules were observed in tendon tissues of MMTAH as compared with facial deformity. Electron microscopy revealed that the muscle and tendon tissues in MMTAH showed degenerative changes and distinctive histological findings as compared with tissues in facial deformity. We found that Ca, P, and Si were detected only in MMTAH.
