Which part of the ear do you check on Otoscopic examination?

outer ear canal
During an ear examination, a tool called an otoscope is used to look at the outer ear canal and eardrum. The otoscope has a light, a magnifying lens, and a funnel-shaped viewing piece with a narrow, pointed end called a speculum.

How do you perform an Otoscopic exam?

The otoscopic exam is performed by gently pulling the auricle upward and backward. In children, the auricle should be pulled downward and backward. This process will move the acoustic meatus in line with the canal. Hold the otoscope like a pen/pencil and use the little finger area as a fulcrum.

What are the parts of an otoscope?

An otoscope consists of a head and a handle and is used to examine the external auditory canal (EAC), the tympanic membrane, and the middle ear. A magnifying lens enhances the clinician’s view.

Is the tympanic membrane concave or convex?

The external surface of the tympanic membrane is concave and the internal surface convex. Surrounding the tympanic membrane is a fibrocartilaginous ring that attaches to the temporal bone, this is called the annulus.

Which part of the ear connects the middle ear to the nasopharynx?

The eustachian tube
Overview. The eustachian tube (pharyngotympanic tube) connects the middle ear cavity with the nasopharynx.

How would you describe the tympanic membrane on a physical exam?

1) Color/shape-pearly grey, shiny, translucent, with no bulging or retraction. 2) Consistency – smooth. 3) Landmarks.

How do you examine Eustachian tubes?

In the Eustachian tube function perforated test, put the probe into the ear increase that pressure to +400 decapascals and hold it. When you get to the peak pressure of +400 decapascals, have the patient swallow. When they swallow, the Eustachian tube should open and close. You’ll see the tracing at positive 400.

What is the tympanic membrane?

The tympanic membrane is also called the eardrum. It separates the outer ear from the middle ear. When sound waves reach the tympanic membrane they cause it to vibrate. The vibrations are then transferred to the tiny bones in the middle ear. The middle ear bones then transfer the vibrating signals to the inner ear.

Is tympanic membrane permeable?

Background. Past in vivo studies in humans showed that the tympanic membrane (TM) is permeable to physiological gases. Animal studies show that transTM CO2 conductance is increased by TM pathology.
