Osseous Hamartoma Arising from the Eustachian Tube

Osseous Hamartoma Arising from the Eustachian Tube

A fairly quite rare case of osseous tumor arising from the Eustachian tube (ET) is described. A 56-year-old man presented with a smooth bulky mass in the nasopharynx and secretory otitis media in the right ear. Computed tomography and magnetic resonance imaging indicated a solid tumor-like region occupying the nasopharynx with apparent extension to the right ET. Transnasal endoscopic surgery de...

Update on eustachian tube dysfunction and the patulous eustachian tube.

PURPOSE OF REVIEW The purpose of this review is to summarize the recent knowledge on eustachian tube dysfunction and the patulous eustachian tube. RECENT FINDINGS A clinically useful test for eustachian tube function is still lacking. Narrowing of the isthmus alone was demonstrated to be an insufficient cause of otitis media. Inflammatory mediators identified within the eustachian tube and mi...

Dermoid of the eustachian tube.

A novel diagnostic tool for chronic obstructive eustachian tube dysfunction—the eustachian tube score.

OBJECTIVES/HYPOTHESIS The purpose of this study was to introduce a new tool for the diagnosis of chronic obstructive eustachian tube dysfunction (ETD) and as a follow-up tool for eustachian tube therapy using objective and subjective elements. STUDY DESIGN Combined, prospective, retrospective clinical study at a tertiary referral center. METHODS Physical examination, history, tympanometry, ...

Eustachian tube surfactant is different from alveolar surfactant: determination of phospholipid composition of porcine eustachian tube lavage fluid.

Phosphatidylcholine (PC) is the main phospholipid in lung surfactant and, more specifically, dipalmitoyl PC (PC16:0/16:0) is the major surface-active component. Several studies have tentatively shown that eustachian tube lavage fluid (ETLF) contains surface-active material. The aim of the present study was to determine, using electrospray ionization mass spectrometry, whether the phospholipid m...
