Abstract：
OBJECTIVE: The aim of the present study was to describe and evaluate the results of a new technique in endolymphatic sac decompression surgery.
METHODS: Forty-three patients with intractable unilateral Meniere\'s disease were selected. Endolymphatic sac was identified after simple mastoidectomy, and its lateral layer was incised, using a sickle knife. Outer layer of the sac was turned around and placed under the anterior bony border.
RESULTS: Mean duration of the follow-up was 24 months. Mean tinnitus handicap index, pure tone average (PTA) on thresholds at 500, 1000, 2000, and 4000 Hz, mean speech reception threshold, mean speech discrimination score, hearing stage, and mean vertigo score before and after surgery were evaluated.
CONCLUSIONS: The new marsupialization technique with anterior bony border is a safe and effective way to improve tinnitus, vertigo, and ear fullness among these patients. According to PTA and hearing stage, this surgery can control progressive hearing loss.
METHODS: 3.

摘要：
目的：本研究的目的是描述和评估一种内淋巴囊减压手术的新技术的结果。
方法：选择43例难治性单侧梅尼埃病患者。单纯乳突切除术后发现内淋巴囊，它的横向层被切开，用镰刀.将囊的外层翻转并置于前骨边界下方。
结果：平均随访时间为24个月。平均耳鸣障碍指数，在500、1000、2000和4000Hz的阈值上的纯音平均(PTA)，平均语音接收阈值，平均言语歧视得分，听力阶段,评估手术前后的平均眩晕评分。
结论：带前骨缘的新型有袋化技术是改善耳鸣的安全有效方法，眩晕,这些患者的耳朵丰满。根据PTA和听力阶段，这种手术可以控制进行性听力损失。
方法：3.
