Acoustic resistance, reactance and phase angle were assessed for the two probe tone frequencies (220 and 660 Hz) on 29 otosclerotic middle-ear systems under accurately defined experimental conditions. Only otosclerotics with normal tympanic membranes were accepted in this statistical survey. The main purpose of these measurements was to provide numerical(More)
The so-called perivascular epithelioid cell neoplasm (PEComa) family includes angiomyolipoma, clear cell 'sugar' tumor (CCST), lymphangioleiomyomatosis, and clear cell myomelanocytic tumor (CCMMT). These rare tumors are characterized by the co-expression of melanocytic and muscle markers. They have been recognized in an increasing number of sites but(More)
The Tubal-compliance-manometric test (TCM) assesses the passive and active tubal opening as well as the equilibration ability. The pressures necessary to open the eustachian tube (ET) are measured while performing the Valsalva maneuver and during swallowing (if needed with added pressure). The equilibration ability is also checked. Subjects with normal(More)
We studied a group of adults and a group of children. All the test subjects were member of the swimming club and were subjected to an intensive training program for competition swimming. Two easy to perform Eustachian tube tests were compared, i.e. the Bluestone 9 steps test (tympanometry) and the measurement of the opening pressure with a pressure(More)
A formula has been elaborated to estimate the resonance frequency of the middle ear from non-simultaneously recorded susceptance and conductance tympanograms at 220 and 660 Hz. The formula is tested on 30 normal and 29 otosclerotic ears. From these experimental results one can conclude that the middle-ear model (proposed by Lutman), from which the formula(More)
An electronic test module is designed in order to monitor field failures of board assembly interconnections while simultaneously measuring the environmental loading conditions. The test module is built-in on the ceiling of a daily driving bus. During operation, when the engine is on, daisy chain interconnections as well as temperature and accelerometer(More)
It was our aim to analyse the frequency spectra of these different stimuli in order to select the most suitable stimulus as one wants to apply BER either as objective audiometry or as oto-neurological means of diagnosis. The kind of stimulus is important because its characteristics will condition the parameters of the electro-physiological response. As(More)
