How do you describe the perforated tympanic membrane?

A ruptured eardrum (tympanic membrane perforation) is a hole or tear in the thin tissue that separates your ear canal from your middle ear (eardrum). A ruptured eardrum can result in hearing loss. It can also make your middle ear vulnerable to infections.

What is tympanic membrane retraction?

A tympanic membrane retraction, or retracted eardrum, is a condition where the tympanic membrane, or eardrum, gets pulled toward the middle of your ear. The tympanic membrane is a thin layer of tissue found between your inner and outer ear.

What is marginal perforation of tympanic membrane?

Information: A marginal perforation is a perforation that has an area with no tympanic membrane between the perforation and the bony canal. Because of this, squamous epithelium may grow into to the middle ear cavity.

What are the landmarks of the tympanic membrane?

The most prominate landmark on the tympanic membrane is the malleus handle. The pars tensa forms the majority of the membrane with the pars flaccida in a triangular shape superiorly.

What causes tympanic membrane perforation?

Tympanic membrane perforation is when there is a tear in the tympanic membrane leading to a connection between the external auditory canal and the middle ear. This can be caused by infection, trauma, or rapid changes in pressure leading to sudden otalgia, otorrhea, tinnitus, and vertigo.

What does it mean if your tympanic membrane is bulging?

A bulging eardrum can be caused by many different things, such as an ear infection. It can affect hearing because it impairs the eardrum’s ability to vibrate and transmit sound. When the eardrum is inflamed, it can cause a person to experience fullness in their ear, ear pain, and pressure.

In which patient is ear irrigation considered appropriate?

Ear irrigation can be an effective earwax removal method for people who have a buildup of earwax in one or both of their ears. Excess earwax can lead to symptoms that include hearing loss.

What would you document when describing the appearance of a normal tympanic membrane?

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

What does the tympanic membrane do?

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.

Where does the tympanic membrane converge to the malleolar fold?

Anterior and posterior malleolar fold: Converges to the lateral process of malleus from 2 ends of the tympanic notch of Rivinus Pars flacidda/Sharpnell membrane/Rivinus membrane: Part of relatively lax membrane lying above the malleolar folds; lack middle fibrous layer

Which is a lax part of the tympanic membrane?

Its periphery is thickened to form a fibrocartilaginous ring called the annulus tympanicus which fits in the tympanic sulcus. Part flaccida: It is the small triangular upper part situated between anterior and posterior malleolar folds. This part is lax due to the absence of fibrous layer.

Is the pars flaccida part of the tympanic membrane?

There are two areas of the tympanic membrane called the pars flaccida and the pars tensa. The pars flaccida is the smaller, more flaccid part of the tympanic membrane in its upper region, while the pars tensa is the largest part of the tympanic membrane situated within a fibrocartilaginous ring, called the tympanic ring.

Where is the notch of the tympanic ring?

Tympanic notch of Rivinus/Rivinus incisure: Notch (deficient area) in the superior part of fibrocartilaginous tympanic ring bridged by pars flaccida. Cone of light/Light reflex: In the antero-inferior quandrant, below and anterior to the handle of malleus
