    ABSTRACT: Summary  The articular disc plays an important role as a stress absorber in joint movement, resulting in stress reduction and redistribution in the temporomandibular joint (TMJ). The flow of synovial fluid in the TMJ may follow a regular pattern during movement of the jaw. We hypothesised that the regular pattern is disrupted when the TMJ disc is perforated. By computed tomography arthrography, we studied the upper TMJ compartment in patients with small disc perforation during jaw opening-closing at positions from 0 to 3 cm. Finite element fluid dynamic modelling was accomplished to analyse the pattern of fluid flow and pressure distribution during the movements. The results showed that the fluid flow in the upper compartment generally formed an anticlockwise circulation but with local vortexes with the jaw opening up to 2 cm. However, when the jaw opening-closing reached 3 cm, an abnormal flow field and the fluid pressure change associated with the perforation may increase the risk of perforation expansion or rupture and is unfavourable for self-repair of the perforated disc.

    ABSTRACT: To explore the feasibility of a novel surgical management technique for severe, chronic granular myringitis with diffuse granulation tissue over the tympanic membrane, with or without involvement of the external auditory canal. Study design: This was a retrospective design. A surgical technique combining tympanic epithelial avulsion with overlay myringoplasty was used to treat 21 severe cases. All 21 cases were cured after one operation. Three months after surgery, patients' tympanic membranes had returned to normal, and their air-bone gaps were less than 10 dB. This new surgical procedure represents improved treatment for severe, chronic granular myringitis.
