What is the Scutum in the ear?

The scutum (plural: scuta) is a sharp bony spur that is formed by the superior wall of the external auditory canal and the lateral wall of the tympanic cavity. It forms the lateral margin of Prussak space.

What is Mesotympanum?

The mesotympanum (rare plural: mesotympana) forms the main compartment of the tympanic cavity and contains most of the important structures of the middle ear, including most of the ossicular chain.

What are the parts of the middle ear?

The middle ear is an air-filled cavity that sits between the tympanic membrane [3] and the inner ear. The middle ear also consists of three tiny bones called ossicles [4], the round window [5], the oval window [6], and the Eustachian tube [7].

What is Prussak’s space?

Prussak space is a subcomponent of the lateral epitympanic space and extends from the level of the scutum to the umbo. This space is best demonstrated on the oblique coronal image.

Where is the attic of the ear?

The attic, just above the eardrum, is where the middle ear meets the mastoid. The attic contains the head of the malleus and the body of the incus. These two ossicles are very commonly surrounded by cholesteatoma.

What is MacEwen triangle?

The MacEwen triangle (also called the suprameatal triangle or mastoid fossa) is a surgical landmark on the surface of the temporal bone just superior to the external auditory canal used to locate the level of the mastoid antrum.

What is Jacobson nerve?

Jacobson’s nerve is a tympanic branch of the glossopharyngeal nerve, arising from its inferior ganglion. It enters the middle ear cavity through the inferior tympanic canaliculus, runs in a canal on the cochlear promontory and provides the main sensory innervation to the mucosa of the mesotympanum and Eustachian tube.

What type of hearing loss is cholesteatoma?

Typically, cholesteatomata patients suffer from conductive hearing loss, i.e., a hearing disorder that only affects the outer ear. If the cholesteatoma is so far advanced that the inner ear is already affected, a so-called sensorineural hearing loss is present.

What does cerumen do to the eardrum?

Earwax — medically known as cerumen — acts to protect and lubricate the ear. Cerumen impaction, or the accumulation of earwax at the eardrum, can sometimes occur even though the ears are normally “self-cleaning.”.

How do you put saline solution in your ear?

This combination of warm water and salt is what gives the saline solution its name. “Saline” means containing salt. Use a cotton ball to drip the saline solution into your ear. Soak a cotton ball in the solution and tilt your head to the side. Place the cotton ball in your ear for 1 minute.

What’s the best way to make an ear cleaner?

Tilt your head to drop the fluid into your ears. Use the ear dropper to drop 1-2 drops of oil into your ear. As the oil enters your ear canal, keep your head tilted to let it drip down to the earwax. It may feel a little chilly. This is completely normal and will pass quickly!

Can you get cerumen impaction in your ears?

Cerumen impaction, or the accumulation of earwax at the eardrum, can sometimes occur even though the ears are normally “self-cleaning.” Symptoms of this include ear aches, partial or complete hearing loss, ringing in the ears, itchiness, ear odor or discharge, and a feeling of fullness in the ears.
