Microbial alpha diversity in the intestine negatively correlated with disease duration in patients with Meniere's disease.

Ménière's disease (MD) is characterized by loss of balance and hearing disorders. Although there is known to be endolymphatic hydrops involved in the pathological process, the pathogenesis of the disease is still largely unclear. Approximately half of patients with MD suffer from depressive symptoms and high levels of several stress hormones were observed in MD and depression, simultaneously.

Experience With Transcanal Endoscopic Ear Surgery and Preoperative Imaging in the Case of Persistent Stapedial Artery.

The persistent stapedial artery (PSA) is an exceedingly vascular anomaly that can lead to hearing loss or pulsatile tinnitus, yet its preoperative diagnosis is often challenging. We report the case of a 24-year-old woman with bilateral PSA and stapes ankylosis who presented with progressive bilateral mixed hearing loss. The patient was initially diagnosed with bilateral congenital stapes ankylosis and stapes surgery was performed on the left side using transcanal endoscopic ear surgery (TEES).

Perilymphatic fistula with characteristic findings of the inner ear by contrast-enhanced magnetic resonance imaging: a case report.

A perilymphatic fistula (PLF) presents with abnormal traffic in the otic capsule, causing cochlear and vestibular symptoms. However, the mechanisms underlying symptom recurrence remain controversial. Herein, we report the case of a 27-year-old female who complained of hearing disturbance in her right ear and recurrent vertigo after sudden onset of hearing loss with vertigo.
