对软腭机能不全,曾用各种材料及方法进行矫治,但由于并发症多而放弃。作者建议注射 Gax 胶,充填咽后壁,形成脊状隆起,收到满意效果。Gax 胶是一利溶解于磷酸盐缓冲液的高纯度牛皮胶悬液,含Ⅰ型胶95%以上,Ⅲ型胶1～5%,通过胶分子非螺旋状的氨基末端(amino-terminal)和羧基末端(car-boxy-terminal)的选择性水解作用而制备,抗原性低,与0.0075%戊二醛交叉结合。其优点:①致敏性在1%以下,胶原纤维实变,未实变部分经盐水排除;②可最大限度地防止成
On the soft palate insufficiency, had a variety of materials and methods for correction, but due to complications and give up. The authors suggest injecting Gax glue, filling pharyngeal wall, the formation of ridge bulge, received satisfactory results. Gax glue is a high-purity leather gel dissolved in phosphate buffer solution, containing more than 95% of type I glue and 1 to 5% of type III glue. Through the non-helical amino-terminal of glue molecule and Carboxy-terminal (car-boxy-terminal), low antigenicity, cross-binding to 0.0075% glutaraldehyde. Its advantages: ① less than 1% allergenicity, collagen fibers consolidation, the real part of the exclusion of salt; ② can be prevented to the maximum
