Chronic suppurative otitis media (CSOM) is middle ear inflammation that results in a perforated tympanic membrane with discharge from the ear for more than six weeks. [7] It may be a complication of acute otitis media. [4] Pain is rarely present. [4] All three types of otitis media may be associated with hearing loss.
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. An otoscope can be used to view the eardrum to diagnose a perforation. Perforations may heal naturally or require surgery.
Tympanometry is an acoustic evaluation of the condition of the middle ear [1] 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. It is not a hearing test, but rather a measure of energy transmission through the middle ear. It is ...
This test tells the audiologist how well the eardrum and other structures in the middle ear are working. The ear canal volume indicates whether a perforation in the eardrum (tympanic membrane) may be present. The middle ear pressure indicates whether any fluid is present in the middle ear space (also called "glue ear" or "otitis media with ...
This test is usually abnormal with conductive hearing loss. A type B tympanogram reveals a flat response, due to fluid in the middle ear (otitis media), or an eardrum perforation. [5] A type C tympanogram indicates negative middle ear pressure, which is commonly seen in eustachian tube dysfunction. [5]
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 changes in pressure of sound from the air to the ossicles inside the middle ear, and thence to the oval window in the ...
Otitis media, cholesteatoma [1] Types: Dilatory, baro-challenged induced, patulous [1] Causes: Common cold, influenza, allergic rhinitis, sinusitis [1] Differential diagnosis: Endolymphatic hydrops, temporomandibular joint dysfunction, superior canal dehiscence syndrome, labyrinthine fistula [1]
Perforated tympanic membrane: Discharge followed by pain improvement Mastoiditis* Children History of URI >10 days Recent history of URI or ear infection Fevers/chills May see signs of otitis media on exam Pain is located behind the ear with postauricular (i.e. near mastoid process) swelling* Diagnose with CT Chronic suppurative otitis media
