Posture Effect on Tympanic Displacement during Acoustic Stapedial Reflex(Theoretical Consideration).

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Stapedial reflex and ears with high static acoustic admittance.

PURPOSE To evaluate modified acoustic reflex diagnostic protocols for a group of individuals (n = 9) with high peak compensated static acoustic admittance (Y(tm)) tympanograms. METHOD A modified procedure designed to improve acoustic stapedius reflex threshold (ASRT) measurements in individuals with high-admittance tympanograms was employed in both an experimental and a control group. ASRTs w...

Clinical comparison of tympanic membrane displacement with invasive ICP measurements.

OBJECTIVE Tympanic membrane displacement (TMD) measurements may be useful in the management of patients with hydrocephalus if they can be directly associated with measurements of ICP. We have compared TMD measurements using the Marchbanks Measurement System with invasive ICP monitoring. METHODS Twenty-nine patients who were undergoing routine invasive monitoring using a Camino fibre optic ICP...

Effects of Continuous Positive Airway Pressure on Middle Ear Pressure and Acoustic Stapedial Reflex.

OBJECTIVE This study investigated the effects of continuous positive airway pressure (CPAP) on middle ear pressure and acoustic stapedial reflex and the correlation between CPAP and middle ear pressure. STUDY DESIGN Prospective cohort study. SETTING Tertiary hospitals. SUBJECTS AND METHODS Fifty patients with obstructive sleep apnea-hypopnea syndrome were assigned to the study group, and ...
