Middle ear

Middle Ear Case 2A A 60 year old female was seen today for an audiological evaluation following the persistence of fluctuating, hearing loss and tinnitus in her right ear over the last year. She also reports occasional dizziness and aural fullness that affects her right ear more than her left ear. She is currently seeking a hearing aid for her right ear but is wondering if anything may be done to correct her hearing loss. Some additional necessary information may be what was she doing when the tinnitus and hearing loss first started, is the hearing loss increasing over time, and whether or not she is having any balance or facial nerve paralysis. Otoscopy revealed clear ear canals and a normal appearing tympanic membrane for the left ear and…

Middle ear infections are caused by bacteria behind the eardrum causing it to become inflamed causing pain in the ear. It’s more common in children than adults for the reason of the Eustachian tube, which is tube that connects from the middle ear to the pharynx, to be shorter in children than adults making the bacteria easier to get to the middle ear. Other causes of getting a middle ear infection is exposure to secondhand smoking, bottle feeding, daycare centers or if your child has a cold or…

The topic I will be researching about is middle ear infection. Otitis media also known as middle ear infection is a group of inflammatory disease of the middle ear. The 2 types of infections are acute otitis media and otitis media with effusion. A shorter way to say these infections are AOM and OME. AOM is an infection that usually presents with ear pain. OME is typically not associated with symptoms. Aom affects about 11% of people a year,there is about 325 to 710 million cases. Some of the…

As sound waves enter the ear, they travel through the outer ear, the external auditory canal, and strike the eardrum (tympanic membrane) causing it to vibrate. The central part of the eardrum is connected to a small bone of the middle ear called the malleus (hammer). As the malleus vibrates, it transmits the sound vibrations to the other two small bones (incus, stapes) or ossicles of the middle ear, the incus and stapes. As the stapes moves, it pushes a structure called the oval window in and…

Middle ear infection Overview: In typical ear infection, the middle ear (located behind the eardrum) gets inflamed and fills with fluid, a condition called otitis media. Most ear infections, short-term, or acute, usually resolves without any intervention, but if you keep popping up are classified as recurrent infections. Recurrent ear infections can lead to a buildup of fluid in the middle ear that tends not to be reabsorbed. In this case we speak of ear infection in the long term or chronic.…

smaller ear canals, excessive production of earwax and higher incidences of otitis media, which is the inflammation and infection of the middle ear, causing the buildup of pressure and a disruption in hearing. Glue ear is also a common occurrence, particularly in children with Down syndrome. Glue ear is caused by the ineffective drainage of the middle ear due to the narrow pathway in the eustachian tubes. The additional fluids prevent the ossicles from vibrating effectively, thereby causing…

Tympanometry is an examination that provides information about the middle ear function and is a standard clinical procedure for neonates. Typanometry is conducted when the patient is seated in an upright positon with the probe horizontally in the ear canal and pointing medially towards the tympanic membrane. Neonates tend to be tested lying in a cot with one ear facing up and the head in a horizontal position and probe in a vertical position. The authors provided adequate background about how…

Tympanic Membrane Perforation A tympanic membrane perforation is a hole in your eardrum. The eardrum is a thin sheet of tissue that separates your middle ear from your ear canal. It protects your middle ear from germs that can cause infection. A tympanic membrane perforation can cause ear pain and hearing loss. CAUSES This condition may be caused by: An injury, such as: A blow to the side of the head. A fall onto water or a flat surface. Too much pressure on the eardrum,…

Introduction The acoustic reflex (AR) describes the involuntary contraction of the stapedius tendon in response to high-intensity sound (Emanuel, 2009). An intricate neural network, receiving afferent input from the vestibulocochlear nerve and sending efferent output to the facial nerve, controls contraction (Emanuel, 2009). The reflex is intensity-dependent, as particular intensities cause the contraction. Once contracted, it lessens the vibrations traveling through the stapes footplate as it…

recurrent ear infections to determine if surgical intervention is recommended in the way of pressure equalization tubes, which act as a bypass to the eustachian tube. The pathophysiology of this condition is characterized by some form of intrinsic or extrinsic factor resulting in eustachian tube dysfunction from a classic understanding of the disease. However, some studies point to the initial inflammation occurring in the middle ear and the progressing…
