Eustachian tube problems are relatively common complaints to otolaryngologists' offices. However, clinicians should consider other possibilities when traditional therapies fail to improve symptoms. We present a previously not described case of sphenoid-sellar fistula after transphenoidal surgery causing objective and subjective clicking. Laryngoscope, 126:E314-E316, 2016.

A case of oncocytic metaplasia obstructing the Eustachian tube in an elderly patient is described. Histologically, it was similar to Warthin's tumour of the parotid gland. The lymphocytes were predominantly T cell, unlike those of Warthin's tumour which are predominantly B cell. It is proposed that oncocytic metaplasia represents an early stage in the evolution of Warthin's tumour.

Introduction Multiplanar imaging of the Eustachian tube (ET) provides options for visualization its course between nasopharynx and middle ear and, depending on resolution, space-occupying lesions or other topographic changes. Ultrasound offers good soft tissues is already established as intravascular ultrasound (IVUS) in vascular diagnostics fine-tissue pathological In this first study, feasibi...

Learning Objectives: Recent studies on the mastoid structure and function has pointed to an important role in middle ear physiology. The normal function of the middle ear depends on regulation of its pressure relative to ambient pressure, and traditionally gas exchange between the middle ear mucosa and gas pocket has been focused on together with the function of the Eustachian tube. However, re...
