Eustachian tube disorders can lead to chronic otitis media with consecutive conductive hearing loss. To improve treatment and to develop new types of implants such as stents, an adequate experimental animal model is required. As the middle ear of sheep is known to be comparable to the human middle ear, the dimensions of the Eustachian tube in two strains of sheep were investigated. The Eustachi...

We observed 2 cases of malignant melanoma arising from the eustachian tube with MR imaging. In this region, we explored further characteristics of primary mucosal melanoma. We discuss the value of using MR imaging to diagnose and treat patients with melanoma in the eustachian tube. In addition, we introduce the key points to differentiate melanoma from some common diseases in the region.

OBJECTIVES/HYPOTHESIS To propose a definitive standard grading scale in the assessment of adenoid tissue in relation to size, position, and proximity to surrounding anatomic structures. This will allow for better clinical communications among practitioners when treating this pathology, a better understanding of its relationship and how it effects neighboring structures (eustachian tube and choa...

Objective Eustachian tube (ET) dysfunction is most frequently caused by a failure of the ET to adequately open; however, there is currently no reliable method of assessing this. Tubomanometry has recently shown good interindividual repeatability as a measure of ET function by measuring middle ear pressure after the application of regulated nasopharyngeal pressures during swallowing. We present ...

Two patients with congenital dermoids of the eustachian tube presented with recurrent otitis media and chronic otorrhea resistant to antimicrobial therapy. CT demonstrated fat density, homogeneous lesions, filling and expanding the eustachian tube. On MR, signal from the lesions was consistent with fat, and the relationship with the internal carotid artery was better delineated than by CT. Micr...

OBJECTIVE To determine the efficacy of intranasal aqueous triamcinolone acetonide in treating the tympanometric signs and symptoms of eustachian tube dysfunction, such as otitis media with effusion and negative middle ear pressure. DESIGN Randomized, placebo-controlled, double-blind prospective clinical trial. SETTING Tertiary referral clinic. PATIENTS Adults (≥18 years) and children (6-1...

OBJECTIVE To assess the prevalence of middle ear alterations in cystic fibrosis (CF) patients. METHODS In this descriptive study, 120 CF patients aged 5 months to 18 years were assessed by clinical history, otoscopy, and tympanometry. Data on P. aeruginosa colonization and parenteral and/or inhaled aminoglycoside use were also collected from medical charts. RESULTS Clinical history revealed...
