Normal Middle Ears. Clinical Trial
Observation of fluid behavior over a perforated eardrum.
A comparison of the behavior of the gas in normal vs. different kinds of otitis media ears.
Fluid present in middle ears is observed during the regular treatment of patients.
The observation in made during the treatment and not as an additional activity. The fluid is
either a steroids solution or sterile normal saline or ear's mucus discharge, all in
perforated eardrums, either as a part of their intra-tympanic treatment for sudden hearing
loss, or traumatic perforation [considered as the normal ears] compared to otitis media
ears.
The observation is made on bubble formation over the perforation. The time length of the
inspection is about 1 minute, under the microscope, during the treatment.
