本文介绍用颊肌粘膜瓣代替舌瓣封闭腭裂修补后腭瘘孔的方法。手术方法首先将瘘孔周围粘膜切开,呈合页状或去掉表皮,为颊肌粘膜瓣准备受植创。在瘘孔邻近颊粘膜上设计一个从牙槽嵴后端到口角的瓣(图1～2),瓣宽不超过1.5cm,以利供区关闭,并注意不要损伤腮腺导管口。此瓣为包括颊肌在内的肌粘膜瓣。将瓣调转,用5/0～4/0缝线缝于受植面(图3),瓣蒂创面不必缝盖。首先关闭供区创面,然后牢固缝合瓣基部以防术后出现颊脂疝,但应以不影响皮瓣血循环为度。
This article describes the use of buccal mucosal flap instead of the tongue to repair the palate fistula after repaired hole method. Surgical methods First mucosal fistula holes around the cut, was hindered or remove the epidermis, buccal mucosal flap for implant surgery. In the fistula near the buccal mucosa design a ridge from the alveolar ridge to the mouth of the flap (Figure 1-2), the flap width of not more than 1.5cm, in order to facilitate the supply area is closed, and be careful not to damage the parotid duct mouth. This flap is a musculocutaneous flap that includes the buccal muscles. The flap transfer, with 5/0 ~ 4/0 sutures stitched on the implants (Figure 3), flap pedicle wound do not have to sew. First, close the wound for the area, and then firmly suture the base of the flap in order to prevent buccal hernia after surgery, but should not affect the degree of flap blood circulation.
