局部麻醉,在腮腺导管口后上方(距导管口0.5～1.0cm)的颊粘膜作半长圆形切口(附图1),钝分离暴露腮腺导管囊状扩张部(附图2),在导管扩张部形成蒂在前下方的舌形瓣(附图3),把舌形瓣向前下方翻转,在导管扩张部形成窗口(附图4),把舌形瓣和导管窗口边缘同颊粘膜切口边缘缝合(附图5)。这佯,便在原导 Local anesthesia, semi-oblong incision in the buccal mucosa above the mouth of the parotid duct (0.5-1.0 cm from the catheter port) (Figure 1), blunt dissection exposing the parotid duct cystic dilatation (Figure 2) The dilating portion forms a flared flap pedicled in the anterior and posterior direction (FIG. 3), flips the flap forwardly and downwardly, forms a window in the dilator portion of the catheter (FIG. 4), and bridges the flaps of the flap and catheter to the buccal mucosa Edge suture (Figure 5).
