Bagautdinova V.I.
Ultrastructural disorders in the muscle fiber of the masticatory muscles in mandibular fractures
Cytology and Genetics 2000, v 34, number 1, 23-29
Basic impairments of the muscular fibre in fractures of the lower jaw with different localization within terms from several hours to several weeks in persons with various clinical course were studied with help of electronic microscopy. Following treatment of the injury with a "quiet" course, in the tissues studied there was activation of reparative processes up to normalization of the submicroscopic structures. Despite the given treatment, the injury accompanied with predominance of destructive changes in the muscular tissue. In the muscles, a disturbed permeability of depolarization waves was revealed, they causing contraction and relaxation of the muscles.
