Tympanic Disorders: A Case Study

The ear is an extraordinary human organ that many people take for granted until it doesn’t function. It is the only device that allows the human to hear sounds in their environment. The ear is made up of many parts that distinguish various sounds through different means. The ear anatomy and physiology along with how sound waves are transmitted into meaningful sounds will help one understand how hearing loss occurs.

The second diagram is a Tympanogram: this is produced by a tympanography a tool that is used to test the mobility of the tympanic membrane.

The middle ear has three ossicles (tiny bones) the hammer, the anvil, and the stirrup that connect the middle ear to the inner ear. When sound enters your middle ear, it causes the ossicles to vibrate. These vibrations then move into the cochlea, which is filled with fluid. When the vibrations move the fluid that is in the cochlea, it stimulates tiny hair cells that respond to different frequencies of sound. After the tiny hair cells are stimulated, they direct the frequencies of sound into the auditory nerve, as nerve impulses. (ASHA 2013)

Mumps-The child may have ear pain, slight fever, swelling from the jaw to the ear, the swelling will start on one side and may travel to the other.

It is a translucent membrane with a pearly gray color and a prominent cone of light in the anteroinferior quadrant, which is the reflection of the otoscope light (Jarvis 2012). Normally the tympanic membrane has three layers. Those are, the outer epithelial layer, the inner mucosal layer, and middle fibrous layer.

The ear is made up of three parts: the outer ear, the middle ear and the inner ear. The outer ear is responsible for collecting the sound wave, the middle ear increases the sound energy and transmits the sound to the inner ear and finally the inner ear transforms the sound waves into nerve impulses and sends them to the brain. When the sound wave passes the ear canal there is a vibration in the eardrum which affects 3

▸ Symptoms of Otitis Media include ear pain, fever, drainage from the ear, a feeling of pressure inside

When a patient presents with otitis media it is important to distinguish if the diagnosis is acute otitis media or otitis media with effusion (Woo & Wynne, 2012). According to Woo & Wynne (2012) acute otitis media also known as AOM can be recognized as a fluid that becomes present in the middle ear that is commonly associated with fever, otalgia, otorrhea, or an immobile tympanic membrane. Otitis media with effusion presents with the fluid in the middle ear but is absent of other symptoms of illness as described above. Due to the fact that otitis media only assumes a viral role about 35 percent of the time and it can clear up within 7 to 14 days without treatment, it is important to assess the patient’s true risks and benefits with antibiotic

(-- removed HTML --) Practice using the instrument on healthy ears first, in order to gain experience viewing 'normal' colors, textures, and shapes inside of the ear canal. Then you'll be able to notice when cerumen or fluid builds up or tissues become inflamed. Product details should include positioning descriptions and instructions. (-- removed HTML

Otitis Media with Effusion (OME) can be defined as, “The presence of fluid in the middle ear without signs or symptoms of acute ear infection” (Pediatrics, 2004). It can be said that OME is an invisible disorder, as there are no immediate signs or symptoms of an acute ear infection such as ear pain, fever, or displeasure (Williamson, 2007). However, OME can have very significant consequences in the life of a child. Early identification and monitoring of OME can combat against possible speech and language delays, as well as protecting against further structural damage to the middle ear. From a diagnostic standpoint, OME must be differentiated from Acute Otitis Media (AOM), as the appropriate treatment will depend on if a child is suffering

The middle ear, which can be referred to as the Tympanic membrane, is responsible for transmitting sound waves from the outer ear into the inner ear. It accomplishes this by using three bones which are called the auditory ossicles. The three bones involved are the Malleus, the incus and stapes. These bones connect the tympanic membrane (eardrum) to the oval window of the inner ear. Each bone has a special function in the transmission of vibrations that will be discussed below. Although, the middle ear is usually good at maintaining balance and free from organisms; it can also be infected from other factors and complications.

The snail like shape of the cochlear effectively boosts the strength of the vibrations caused by sound, especially for low pitches. When sound waves hit the ear drum, tiny bones in the ear transmit the vibrations to the fluid of the cochlea, where they travel along a tube that winds into a spiral. The tube’s properties gradually change along its length, so the waves grow and then die away, much as an ocean wave travelling towards the shore gets taller and narrower before breaking at the beach.

Since Dax had recently had an audiological evaluation no acuity testing was done. Middle ear functioning was assessed using the tympanometer. The tympanogram showed no peak and increased ear canal volume, which was expected because he had tubes in his ears. The ear canal volume was 3.6 for the left ear and 5.9 for the right ear, which indicated open, functioning PE tubes.

Based on the second resource in Physics, I could not district between frequencies as well as I should. My issue was could tell there was a difference in pitch I just could not tell if it was higher or lower once they got super similar to one another. The biology behind it is that once a pitch has traveled through the ear and the cochlea has transferred it to the brain, the arcuate fasciculus produces the process of distinguishing which pitch is higher or lower than another. Some people can do this better than others based on the way their brain works. But it is all pitch recognition in your brain. Tiny sound waves inside your ear help you tune the pitch and pick up sound waves. They take the sound waves and turn them into nerve signals causing the brain to interpret sound. The enter form the outer ear and travel through the passage of the ear canal. It then reaches the eardrum where the vibrations translate into the sound we hear. It then goes to the cochlea, a snail-shaped structure that contains fluid in the ear. The sound causes the liquid inside to ripple. The wave goes across to the basilar

The peripheral vestibular system consists of a bony labyrinth and a membranous labyrinth. This system sits in the otic capsule in the petrous portion of the temporal bone. The bony labyrinth consists of the cochlea, an oval cavity called the vestibule, and the semicircular canals. The structures of the bony labyrinth are
