为预防引流切口粘连性闭合和修复内淋巴囊的吸收功能,作者发展了一种新的手术方法:先完成单纯乳突凿开术。在认出外半规管的Donaldson线后,钻开乳突气房直至乙状窦和后半规管之间的颅后窝扇形骨板,打开颈静脉球沟,细心钻、刮后半规管环的中央部,辨认Irv氏嵴和盖,暴露内淋巴囊的外侧壁,在其喙缘上用眼科角膜刀作一单纯的直切口;将事先从患者足背上取下的一段6～9mm长的静脉,内衬双层明胶片作为轴芯,将其较宽的一端经切口插入囊内,另一端开向乳突腔,用神经缝合器将静脉缝到内淋巴囊外壁的切口缘上。作者用此法治疗20例梅尼埃病患者,术后随访至少3年,应用1985年美国耳鼻咽喉科-
To prevent the drainage of incision adhesion closure and repair of the lymphatic sac absorption function, the authors developed a new surgical approach: the first complete mastoid surgery. After recognizing the Donaldson line of the semicircular canal, the mastoid cavity was drilled until the skull posterior fossa between the sigmoid sinus and the posterior semicircular canal was opened, the jugular bulb was opened, the center of the semicircular canal was carefully drilled, The Irv ridge and cap were identified, the outer wall of the endolymphatic sac was exposed, and a simple straight incision was made using an ophthalmic knife at its beak margin. A 6 to 9 mm long vein, previously removed from the patient’s dorsum of the foot, A bilayer gelatin tablet is used as a shaft core, one of its wider ends is inserted into the capsule through the incision, and the other end is open to the mastoid cavity. The nerve is stitched to sew the incision margin of the outer lymphatic sac. The authors use this method to treat 20 patients with Meniere’s disease, followed up for at least 3 years, the application of the United States in otolaryngology -
