Definitions

1. The middle ear is the portion of the ear internal to the eardrum, and external to the oval window of the cochlea. (Web site)
2. Within the middle ear are three auditory ossicles: the maleus, incus, and stapes. (Web site)
3. Middle Ear The middle ear is a small, air-filled pocket bounded by the eardrum on one side and the oval window of the inner ear on the other. (Web site)

Weeks

1. In some children whose treatment is successful, fluid will still remain in the middle ear for weeks or months, even after the infection has resolved.

Space

1. Perform otoscopic examinations because extensive polyposis causing eustachian tube dysfunction can cause fluid and infection in the middle ear space.

Results

1. The results of this study support the contention that anaerobic bacteria such as P. acnes may be true pathogens in middle ear infections. (Web site)

Middle Lobe

1. The tegmen is a thin plate of bone that separates the dura of the middle lobe from the middle ear and the mastoid cavity.

Learning Problems

1. If this input is dampened by infection or fluid in the middle ear during this important period, it can cause learning problems. (Web site)

Trouble Hearing

1. Symptoms of a middle ear infection include pain, fever, trouble hearing, problems sleeping, and a swollen eardrum.

Stomach

1. The bladder, gallbladder, stomach, uterus, eye, and cavity of the middle ear all have a fundus.

Lateral Wall

1. The squama of the temporal bone forms the lateral wall of the central air containing space, the antrum, which communicates with middle ear by the aditus.

Second Operation

1. The second operation will attempt to restore hearing and, at the same time, inspect the middle ear space and mastoid for residual cholesteatoma.

Part

1. The air cells are connected to a cavity in the upper part of the bone, which is in turn connected to the middle ear.

Middle Ear Equalization

1. This means that some individuals will virtually never have problems with middle ear equalization while diving.

Middle Ear Pathogen

1. The data suggest that the gram-positive coccus is a newly described middle ear pathogen and may be responsible, in part, for persistent middle ear effusion. (Web site)

Middle Ear Effusion

1. All ears were asymptomatic and no patient had evidence of middle ear effusion.
2. Also called middle ear effusion, this condition often follows the acute infection and lasts for weeks. (Web site)

Fat Pad Extending

1. This walking whale lacked the fat pad extending to the middle ear that modern ceteans have, a clue that it had kept terrestrial attributes.

Middle Ear Cavities

1. The dolphins have middle ear cavities that are independently suspended and surrounded by air-filled spaces, reducing the contact with the bones.

Acutely Infected

1. When the middle ear becomes acutely infected, pressure builds up behind the eardrum (tympanic membrane), frequently causing intense pain. (Web site)

Middle Ear Development

1. Moving on to middle ear development, around the sixth week of gestation, the malleolus and incus appear as a single mass.

Round Window

1. Round window - membrane separating the middle ear and inner ear.

Auditory Tube

1. The auditory tube to the middle ear opens into the lateral wall of the nasopharynx.

Tympanostomy Tube

1. A tympanostomy tube is often inserted into the eardrum to aerate the middle ear.

External Auditory Canal

1. Pneumocystis carinii infection of the middle ear and external auditory canal.

Chronic Otitis Media

1. A buildup of debris in the middle ear from long-term infections such as chronic otitis media, cancer, or a bone infection can cause the problem. (Web site)

Tiny Bones

1. Tiny bones of the middle ear, the conchae and vomer in the nose, and the ethmoid of the orbital vault are not easily seen. (Web site)

Middle Ear Barotrauma

1. There were no other symptoms or signs of DCS or middle ear barotrauma.

External Ear Canal

1. The membrane separating the external ear canal from the middle ear. (Web site)

Ear Drum

1. If glue ear persists, surgery may be needed to remove the glue-like fluid from the middle ear and to place a 'grommet' (ventilation tube) in the ear drum. (Web site)

Middle Ear Works

1. In humans, the middle ear works as an impedance matcher between the outside air’s low impedance and the cochlear fluid’s high impedance. (Web site)

Treat

1. Surgical drainage of the middle ear through the eardrum (myringotomy) may be needed to treat the underlying middle ear infection.

Mastoid Bone

1. The development of the mastoid bone is likewise formed by the extension of the air-filled cavity of the middle ear into the mastoid bone. (Web site)

Ruptured Eardrum

1. Conversely, a ruptured eardrum can cause ear infections because the eardrum is no longer intact, and bacteria can enter the middle ear.
2. Ear infections may cause a ruptured eardrum as the pressure of fluid in the middle ear increases. (Web site)

Mammalian Middle Ear

1. The bones of the mammalian middle ear are a diagnostic of the class. (Web site)

Outer Ear

1. The combined transfer function of the outer ear and middle ear gives humans a peak sensitivity to frequencies between 1 kHz and 3 kHz. (Web site)

Required

1. Active opening of the Eustachian tube is required to equalize the pressure between the middle ear and the surrounding atmosphere as the plane descends.

Soft Palate

1. Raising the soft palate prevents food and liquid from getting in nose and middle ear.

Tongue

1. Visceral elements in the mammalian skeleton include jaws, the hyoid apparatus supporting the tongue, and the auditory ossicles of the middle ear. (Web site)

Common

1. Progression to chronic otitis media is much more common in this group of people, who often have a family history of middle ear disease. (Web site)
2. The incidence of sinus barotrauma in diving is significant but less common than is middle ear barotrauma.

Respiratory

1. Sometimes the respiratory infection leads to acute otitis media, an infection of the middle ear. (Web site)

Causing

1. When the eardrum is perforated, bacteria can easily travel to the middle ear -- causing an infection. (Web site)
2. This is also the pathway that allows infections from the mouth and nose cavities to enter the middle ear, causing the common ear infections of childhood.
3. When the middle ear becomes acutely infected by bacteria, pressure builds up behind the ear drum, usually but not always causing pain. (Web site)

Head

1. The head contains a number of gas-filled cavities which communicate with the nose; these are the middle ear cavities and the nasal sinuses.

External

1. External and middle ear, opened from the front.

Sides

1. They are the outer ear (the part we see along the sides of our head behind the temples), the middle ear, and the inner ear.

Side

1. The middle ear of tetrapods is homologous with the spiracle of fishes, an opening from the pharynx to the side of the head in front of the main gill slits. (Web site)
2. By permitting air to leave or enter the middle ear, the tube equalizes air pressure on either side of the eardrum - see equalisation. (Web site)

Eyes

1. Head, face, upper neck, inner & middle ear, sympathetic nerve system, sinuses, eyes, auditory nerves and more. (Web site)

Vigorous

1. In diving this can happen when the pressure in the middle ear is too low and the valsalva manoeuvre is too vigorous.

Result

1. The inflammation occurs as a result of a middle ear infection. (Web site)
2. Also middle ear infections are associated with disturbances involving the temporal lobe which result in TLE (Kotagal & Luders, 1999). (Web site)
3. There may also be fluid (serous otitis media) present in the middle ear as a result of the differential pressure.

Blockage

1. Obstruction of blockage of the Eustachian tube results in a vacuum effect in the middle ear, creating negative middle ear pressure. (Web site)
