Abstract

Eustachian tube dilation (ETD) is an established, minimally invasive therapeutic approach for chronic eustachian tube dysfunction. The complications associated with performing a ETD are rare. A 22-year-old female patient presented with chronic otitis media on the right side and chronic obstructive tube dilation disorder on both sides. A type I tympanoplasty was performed on the right side because of a tympanic membrane perforation after a ETD on both sides without apparent complications. On the 5th postoperative day, she presented with headache, dizziness and hearing loss on the right side. There was a decrease of hearing threshold on the right side in the pure-tone audiogram and vHIT, cVEMP, and SVV were irregular. The β-2-transferrin test was positive. Since a right-sided perilymph fistula was suspected, an emergency tympanotomy was performed with a round window membrane cover with fascia on the right side. Intraoperatively, a regular, intact ossicular chain was found with a slightly moist middle ear mucosa. The round window membrane was covered by the promontorial lip. Under these measures, the patient's dizziness regressed. The right ear pure-tone threshold vHIT, cVEMP, and SVV normalized.

咽鼓管扩张和鼓室成形术的并发症——淋巴周围瘘
耳咽管扩张(ETD)是一种成熟的微创治疗慢性耳咽管功能障碍的方法。与ETD相关的并发症是罕见的。一位22岁的女性患者表现为右侧慢性中耳炎和两侧慢性阻塞性管道扩张障碍。由于双侧ETD后鼓膜穿孔,右侧行I型鼓室成形术,无明显并发症。术后第5天,患者出现头痛、头晕、右侧听力下降。纯音听力图右侧听阈降低,vHIT、cvpp、SVV不规则。β-2转铁蛋白试验呈阳性。由于怀疑右侧淋巴周围瘘管,我们在右侧进行了一个圆形膜覆盖的紧急鼓室切开术。术中发现规则完整的听骨链,中耳黏膜微湿。圆形的窗膜被突起的唇盖住。在这些措施下,病人的头晕消退了。右耳纯音阈值vHIT、cVEMP和SVV归一化。
