Computerised tomography (CT) can be used to determine if disease is present in the middle ear. [12] Whilst hearing loss is a common symptom in many diseases of the ear, for example in otosclerosis (abnormal bone growth in the ear), [3] the white, chalky patches on the tympanic membrane are fairly characteristic of tympanosclerosis ...
Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position. The eardrum comprises two parts: the pars tensa, which is the main part of the eardrum, and the pars flaccida, which is a smaller part of the eardrum located above the pars tensa. Either or both of these parts ...
It has been suggested that bulging of the tympanic membrane is the best sign to differentiate AOM from OME, with a bulging of the membrane suggesting AOM rather than OME. [23] Viral otitis may result in blisters on the external side of the tympanic membrane, which is called bullous myringitis (myringa being Latin for "eardrum"). [24]
Otomycosis does not usually cause as much canal skin edema as does acute bacterial external otitis.While a severe pressure type of pain is a prominent feature of advanced cases, the ear is usually much less tender, if at all, to traction or tragal pressure.
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.
Conductive hearing loss (CHL) occurs when there is a problem transferring sound waves anywhere along the pathway through the outer ear, tympanic membrane (eardrum), or middle ear . If a conductive hearing loss occurs in conjunction with a sensorineural hearing loss, it is referred to as a mixed hearing loss.
Granular myringitis is a long term condition in which there is inflammation of the tympanic membrane in the ear and formation of granulation tissue within the tympanic membrane. [1] It is a type of otitis externa. [2] Without treatment it can lead to narrowing of the ear canal. [1]
One end of malleus is connected to the tympanic membrane, and the other end is connected to the two other ossicles, the incus and stapes, which connects to the inner ear. The purpose of the middle ear is to deliver the sound waves from the outer ear to the cochlea of the inner ear. When external sound contacts the eardrum, the ossicles vibrate.
