Diseases of The Middle Ear
In serous otitis media which one of the. following statements is true?
|A||Sensorineural deafness occurs as a compli-cation in 80% of the cases|
|B||Intracranial spread of the infection complicates the clinical courses|
|C||Tympanostomy tubes are usually required for treatment|
|D||Gram-positive. organisms...are grown routinely In .culture in the aspirate|
Lets see at the options one by one:
Serous otitis media:
Sensori neural deafness occurs as a complication in 80% of cases
This is not correct because serous otitis media leads to conductive type of hearing loss.
Intracranial spread of the infection complicates the clinical course
a. This is not true as complications of serous otitis media are:
b. Adhesive otitis media
c. Atrophy of tympanic membrane
d. Tympanosclerosis (chalky white deposits seen on. membrane)
e. Atelectasis of middle ear
f. Ossicular necrosis
g. Cholesteatoma due to retraction pockets
h. Cholesterol granuloma due to stasis of secretions
a. Tympanostomy tubes are usually required for treatment:
b. This is quite correct as myringotomy and aspiration of middle ear effusion without ventilation tube/Tyrnpanostomy tube/ grommet insertion has a short lived benefit and is not-recommended
c. Hence if otitis media with effusion I serous OM is notresolved spontaneously, tympanostomy tube is inserted.
a. Gram positive organism are grown routinely in culture in the aspirate
b. Absolutely incorrect because fluid collection in serous otitis media ls sterile
