To examine whether intratympanic injection of dexamethasone is effective in controlling vertigo in patients with Ménière's disease who have persistent vertigo despite standard medical treatment, including a low-salt/no-caffeine diet and diuretics.
A prospective study.
From August 1999 to November 2000, 21 patients with intractable Ménière's disease underwent intratympanic injections of 4 mg/mL dexamethasone over a period of 4 weeks as an office procedure. American Academy of Otolaryngology-Head and Neck Surgery guidelines for the definition and reporting of results in Ménière's disease were used.
Complete relief of vertigo was maintained in 11 of the 21 patients (52%) at 3 months and in 9 of 21 patients (43%) at 6 months. Repeat injections in 5 patients who had initial control of vertigo, but later failed, yielded control in 3 (60%) patients. The complication rate was low: one patient had a 35-decibel pure tone average decrease in hearing during treatment and one patient had a persistent tympanic membrane perforation.
Intratympanic injections of dexamethasone are a reasonable initial surgical treatment for persistent vertigo in Ménière's disease. The principal benefits are avoidance of systemic administration of steroids, lower cost than endolymphatic sac surgery, and ease of administration as an office procedure. The disadvantages are the need for repeated office visits for injections and the decreasing effectiveness over time.
探讨对于尽管接受了包括低盐/无咖啡因饮食及利尿剂在内的标准药物治疗但仍有持续性眩晕的梅尼埃病患者,鼓室内注射地塞米松是否能有效控制眩晕。
一项前瞻性研究。
1999年8月至2000年11月,21例难治性梅尼埃病患者在4周内作为门诊手术接受了浓度为4mg/mL的地塞米松鼓室内注射。采用美国耳鼻咽喉-头颈外科学会关于梅尼埃病结果定义和报告的指南。
21例患者中有11例(52%)在3个月时眩晕完全缓解,21例中有9例(43%)在6个月时眩晕完全缓解。5例最初眩晕得到控制但后来复发的患者再次注射后,3例(60%)眩晕得到控制。并发症发生率较低:1例患者在治疗期间纯音平均听阈下降35分贝,1例患者鼓膜持续穿孔。
鼓室内注射地塞米松是梅尼埃病持续性眩晕合理的初始手术治疗方法。主要优点是避免了全身使用类固醇,成本低于内淋巴囊手术,且作为门诊手术易于实施。缺点是需要多次门诊注射,且随着时间推移效果会降低。
