OBJECTIVES
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.
CONCLUSION
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.
LEVEL OF EVIDENCE
目的
本研究旨在描述和评估内淋巴囊减压手术新技术的结果。
方法
选取43例单侧难治性梅尼埃病患者。在简单乳突切除术后识别内淋巴囊，并用镰状刀切开其外层。将囊的外层翻转并置于前骨缘下方。
结果
平均随访时间为24个月。评估了手术前后的平均耳鸣障碍指数、500、1000、2000和4000赫兹阈值处的纯音平均听阈（PTA）、平均言语接受阈、平均言语辨别得分、听力分级和平均眩晕得分。
结论
采用前骨缘的新袋形缝合技术是改善这些患者耳鸣、眩晕和耳胀满感的一种安全有效的方法。根据PTA和听力分级，该手术可控制进行性听力损失。
证据级别
3级。
