Abstract

The objective of this study is to evaluate the traumatic internal change of temporomandibular joint with mandibular fractures through the synovial fluid cell counts from the superior joint space. Synovial fluids were collected from 21 TMJ of fractured side and 15 TMJ of non-fractured side of 19 patients with mandibular fractures. The collected synovial fluid more than 1ml was stored in the EDTA tube immediately. The synovial fluid was evaluated for calculation of the number of RBC, WBC and the percentage of lymphocyte, polynuclear cell using Cytospin3(SHANDON). In fractured side, the average number of RBC and WBC were 175,819/microliter, 281.9/microliter, and the average percentage of polynuclear cell and lymphocyte were 68.9%, 11.7% respectively. In non-fracutred side, the average number of RBC and WBC were 7,939/microliter, 10.53/microliter and the average percentage of polynuclear cell and lymphocyte were 47.4%, 9.4% respectively.
