Bullous myringitis, often caused by viruses and sometimes by bacteria, inflames the eardrum, forming fluid-filled blisters. It can be associated with middle or external ear infections but the main focus on the eardrum and nearby skin.
A myringotomy is a surgical procedure in which an incision is created in the eardrum (tympanic membrane) to relieve pressure caused by excessive buildup of fluid, or to drain pus from the middle ear. A tympanostomy tube may be inserted through the eardrum to keep the middle ear aerated for a prolonged time and to prevent reaccumulation of fluid.
Treatment. conservative or surgery. Normal ear drum. A perforated eardrum ( tympanic membrane perforation) is a prick in the eardrum. It can be caused by infection ( otitis media ), trauma, overpressure (loud noise ), inappropriate ear clearing, and changes in middle ear pressure.
Tympanostomy tube, also known as a grommet, myringotomy tube, or pressure equalizing tube, is a small tube inserted into the eardrum via a surgical procedure called myringotomy to keep the middle ear aerated for a prolonged period of time, typically to prevent accumulation of fluid in the middle ear. [1] The tube itself is made in a variety of ...
Otic polyp. Otic polyp. Other names. Aural polyp. An intermediate magnification of a H&E stained biopsy from an otic polyp. Specialty. ENT surgery. An otic polyp is a benign proliferation of chronic inflammatory cells associated with granulation tissue, in response to a longstanding inflammatory process of the middle ear. [1] [2]
e. In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. Its function is to transmit sound from the air to the ossicles inside the middle ear, and thence to the oval window in the fluid-filled cochlea.
Patulous Eustachian tube is the name of a physical disorder where the Eustachian tube, which is normally closed, instead stays intermittently open. When this occurs, the person experiences autophony, the hearing of self-generated sounds. [1] These sounds, such as one's own breathing, voice, and heartbeat, vibrate directly onto the ear drum and ...
Earmold. Impression material being mixed together. This is the start of the mixing process, as the material needs to be one color. An earmold (also spelled; ear mold, ear mould or earmould) is a device worn inserted into the ear for sound conduction or hearing protection. Earmolds are anatomically shaped and can be produced in different sizes ...
Tympanometry is an acoustic evaluation of the condition of the middle ear eardrum (tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal. Tympanometry is an objective test of middle-ear function.
The promontory of the tympanic cavity, also known as the cochlear promontory is a rounded hollow prominence [citation needed] upon - and most prominent feature of - the medial wall of the tympanic cavity formed by the underlying first turn of the cochlea. The surface of the promontory is furrowed by fine grooves that accommodate to the strands ...
