Abstract:

Eustachian tube dysfunction is a nearly universal complication of cleft palate, resulting in chronic ear disease and conductive hearing loss. Cleft palate repair is thought to result in recovery of eustachian tube function, but the length of time between repair and recovery of eustachian tube function is not known. Furthermore, the efficacy of tympanostomy tubes in the treatment of eustachian tube dysfunction and hearing sequelae has not been examined in a systematic way. To answer these questions, we performed a retrospective study that used serial audiometric data and tympanometry on 81 pati

Abstract:

AbstractThe Eustachian tube acts as pressure equalizing tube between the nasopharynx and the middle ear. It also functions as a conduit for removal of secretions from the middle ear and mastoid air cell system into the post nasal space. Eustachian tube function may be assessed objectively using tympanometric measurements. (Brooks, 1968, Lutman, 1987).The post-operative use of nasogastric Ryles tubes is associated with reduced peak middle ear pressure (mmH2O) and reduced peak compliance volumes (ml) as assessed by tympanometry. In addition changes in the appearance of the tympanic membrane may

INTRODUCTION: The role of allergy in eustachian tube dysfunction is controversial. In this study, allergy was simulated by exposure to histamine, and eustachian tube function testing was performed in an experimental rat model. METHODS: Ventilatory function was assessed by measuring passive opening and closing pressures of the eustachian tube after challenge with either transtympanic or intranasal histamine. The mucociliary clearance time of the tubotympanum was assessed by observing dye transport from the middle ear to the nasopharynx after challenge with either transtympanic histamine or cont

Abstract:

The relationship of eustachian tube surfactant and otitis media with effusion on eustachian tube opening pressure was studied in a gerbil model. Injection of killed Streptococcus pneumoniae bacteria created a serous effusion that increased eustachian tube opening pressure. The introduction of exogenous surfactant to this system resulted in a dramatic decrease in eustachian tube opening pressure in both normal ears and those with effusion. Identifying means to increase surfactant in the eustachian tube could be beneficial in reducing persistent otitis media with effusion.

AbstractBackgroundDefining the risk factors for Eustachian tube dysfunction can facilitate its prevention. It is hypothesised that Eustachian tube dysfunction as measured by the Eustachian Tube Dysfunction Questionnaire-7 is associated with obstructive sleep apnoea syndrome.MethodsThe questionnaire was systematically translated into Hebrew and validated in the accepted manner. This questionnaire was applied to obstructive sleep apnoea syndrome patients before and after expansion sphincter pharyngoplasty, in pre-set time intervals. The results were compared to those of controls from the general

Abstract:

AbstractImpairment of Eustachian tube function with nonsufficient ventilation of the middle ear is a main cause for chronic otitis media. To provide an effective and safe therapy, the innovative concept of Eustachian tube stenting was established. Biodegradable polymeric stents are developed to restore impaired tube function and dissolve after fulfilling their supportive purpose. To evaluate the applicability of the stents in the Eustachian tube, prototypes in conjunction with corresponding implantation instruments were tested in human cadaver studies.

Educational objectives: To understand three-dimensional anatomy and function of the eustachian tube and consequently the pathology and dysfunction of the eustachian tube that are closely associated with those of the middle ear, such as otitis media with effusion, the second most common disease among children, next to the common cold.

Abstract:

Previous experiments have shown that Pseudomonas aeruginosa may infect the middle ears of chinchillas by way of the eustachian tube and that chinchillas with acute otitis media (AOM) are more susceptible to pseudomonas infection than animals without AOM. The purpose of this experiment was to examine the effects of otitis media with effusion (OME), induced by means of eustachian tube obstruction, on middle ear susceptibility to nasal inoculation of P. aeruginosa. Chinchilla eustachian tubes were obstructed with silicone rubber sponge bilaterally; OME developed in eight animals (11 ears)—three b

Abstract:

Relationships between middle ear pressure and non-infection-related cochleovestibular dysfunction have been suggested by several authors. According to some data, vertiginous attacks can be prevented by the insertion of a ventilation tube in patients suffering from Meniere's syndrome. The aim of our study was to investigate if the incidence of eustachian tube malfunction and pathologic middle ear pressure is frequent, and if routine implantation of ventilation tubes is reasonable in ears with dysfunctions of the labyrinth, including clinical Meniere's syndrome. So, we determined in our pressure

Abstract:

The purpose of this study was to develop instructions and procedures and to establish a normal data base for four tympanometric tests of Eustachian tube function: Valsalva, Toynbee, Inflation, and Deflation. Data were obtained for 24 young adults (48 ears) with normal hearing and normal middle-ear function. The tympanograms were analyzed for differences between baseline and experimental (postmaneuver) and baseline and posttest tracings for seven measures: tympanogram peak pressure, peak acoustic admittance, static acoustic admittance, negative gradient, positive gradient, and negative and posi
