You will understand the surgical principles with this model. It's a right Eustachian tube. Main structures involved in tubal opening are shown in different colours. The cartilage, posterior, in grey, supports the entire system to avoid total collapse. TVP muscle, the main tubal muscle, anterior, in dark pink, is covert by the anterior intra tubal mucosa, in dark blue, making together some physiological convexity of the anterior wall in relax state, as a mirror of the posterior cartilaginous concavity. Perfect contact of both of these walls ensure correct closure. This is the tubal valve. When opening, the posterior wall (cartilage) is pushed back by contracting the LVP muscle. The anterior wall runs forward by contracting the TVP muscle, straightening the convex curve (dark blue), creating the channel and tubal aperture. It's a complicated dynamic system, requiring perfect co-ordination of all structures. Any damage or muscular malfunction induces Eustachian tube dysfunction EUSTACHIAN TUBE Institute - SURGERY
