What's the difference between eardrum and myringitis?
Eardrum
Definition:
(n.) The tympanum. See Illust. of Ear.
Example Sentences:
(1) Their use is indicated in large or total defects to restore the natural anatomical conical shape of the eardrum, particularly in congenital atresia.
(2) Primitively, vibrations reached the stapes mainly via the anterior hyoid cornu, but in dicynodonts, therocephalians, and cynodants vibrations passed mainly or exclusively from mandible to quadrate to stapes and the reflected lamina was a component of the eardrum.
(3) An attempt was made to answer the question whether it is justified to set an age limit for performance of eardrum reconstructions in children.

(6) The nature of the acoustic coupling limits the passive energy absorption and transmission properties of the eardrum.
(7) The hierarchy illuminates some of the limitations of various simplified elements commonly used to model the middle ear and demonstrates the necessity of treating the acoustics and the eardrum as an integrated subsystem.
(8) Large variations of sound pressure along the ear canal and over the surface of the eardrum are found above about 10 kHz.
(9) The acoustical energy reflectance at the eardrum, as calculated from a model of the ear canal when terminated by the middle ear model, agrees reasonably well with experimental data up to about 12 kHz.
(10) The tubal compliance index (TCI), which is the ratio of the tubal resistance between two different air flow rates, was compared among three groups: 36 ears of children with otitis media with effusion (OME), 26 ears of adult OME patients, and 10 otherwise normal ears with traumatic perforations of the eardrum.
(11) A major part of this alteration is due to the interaction of various mechanical and acoustic resonances which are characteristic of the hearing-aid receiver and the sound transmission system linking the receiver with the eardrum.
(12) I hope I don't sound too much of fuddy-fuddy -- actually, I know I do -- but surely the point of an athletics meet is to watch athletics and see people run and throw things -- and not to have your eardrums assaulted by a booming bass beat?
(13) The present study also included gross and histopathological examinations of the eardrum and observation of fibers of the lamina propria of the transplanted tympanic membrane by means of polarizing microscopy and of vascularization by intravascular India ink injection.
(14) In cases of retraction of the eardrum, the otoemissions were present in 2 of 23 ears.
(15) However, based on calculations of anticipated leakage of H2S for a variety of eustachian tube conditions and in the absence of either medical literature or personal reports documenting H2S poisoning due to eardrum perforation, the recommendation for excluding workers with such a condition from working in or around H2S is not supported.
(16) The auditory sensitivity of the rats with cotton-stuffed ears and the pierced eardrums decreased about 10 and 20 dB, respectively.
(17) Twenty-five eardrums of 15 healthy children without past or present history of otological disease were examined using otoscopy; a photograph of each eardrum was obtained.
(18) Perforated eardrums were found in 13.9% of Aboriginal and in 0.3% of European children's ears, and this abnormality was strongly associated with low weight and height status.
(19) Revised acoustic energy reflection coefficients, at the eardrum, are obtained for 20 ears for frequencies between 3 and 13 kHz.
(20) Three children whose eardrums appeared normal upon previous examinations, one with the otomicroscope, apparently developed tympanic membrane cholesteatomas that penetrated the fibrous layer of the pars tensa.
Myringitis
Definition:
Example Sentences:
(1) Although the clinical features of myringitis granulosa have been well described by several authors, its pathogenesis is still obscure.
(2) In the case of granular myringitis it is important to differentiate between this disease and chronic suppurative otitis media complicated with polyps or granulations.
(3) Long-term anatomic results of 170 tympanic homografts performed in the Necker-Enfants-Malades hospital, France between 1977 and 1983 showed high frequency of complications: early perforation (17.7%); late perforation (14%); myringitis (8.5%); recurrence of retraction (7.31%); lateralization (9.4%).
(4) On the basis of our present study and available relevant data in the literature, we emphasize that early surgical intervention of a traumatic myringeal perforation is not indicated, as most of these perforations (an average of 88%) do heal spontaneously without complications.
(5) Using a higher dose of FGF, the promoting effect was counterbalanced by a high rate of myringitis.
(6) Twenty-three of them had upper respiratory tract infections with cough and fever; two had pneumonia, one with myringitis.
(7) In the daughter myringitis, pharyngitis, cervical lymphadenopathy and splenomegaly were observed.
(8) Granular myringitis is the result of a localized chronic inflammation of the lateral surface of the tympanic membrane which is characterized by the development and persistence of granulation tissue over the involved area.
(9) Myringeal perforations or major conductive hearing losses persisting 3 months after injury warrant tympanotomy and appropriate reconstruction.
(10) Myringitis granulosa is not a rare pathologic condition of the tympanic membrane.
(11) No drum perforations, no hearing impairments and normal X-ray findings indicated that myringitis granulosa had no relation to chronic suppurative otitis media.
(12) Granular myringitis is a disease which is poorly understood and has received relatively little attention in the literature.
(13) Decelerated migration with desquamation in situ was observed during the quiescent phase of recurrent otitis externa, with or without myringitis.
(14) The findings of this study confirms the fact that sensorineural hearing loss is more common in bullous myringitis than previously thought and that it is temporary in many cases.
(15) Twenty of their ears were diagnosed as having bullous myringitis.
(16) Otological causes included foreign body in the ear (23%), acute otitis media (11%), otitis externa (10%), secretory otitis media (6%) and myringitis bullosa haemorrhagica (4%).
(17) Observations based on two contrasting cases of myringitis bullosa haemorrhagica indicate that tympanosclerosis involving the tympanic membrane may have a significant effect on the clinical course of the disease.
(18) The differential diagnoses of chronic suppurative otitis media and polypoid myringitis are discussed, as well as the properties of formalin, its side effects, and the technique of toilet.
(19) This paper reports three cases of chronic granular myringitis treated with aural toilet using 0.5% formalin.
(20) It is suggested that in some cases formalin may be a more effective agent for chronic granular myringitis than other treatments.
