AAP guideline recommends using pneumatic otoscopy as a primary method for diagnosing OME and tympanometry
can be used to confirm the diagnosis".
, auditory brainstem response (ABR), and distortion product otoacoustic emissions (DPOAEs) were performed.
The hearing evaluation consisted of pure tone audiometry; speech audiometry--Speech Recognition Threshold (SRT) and phonemically balanced monosyllabic words and immitance (tympanometry
and acoustic reflexes).
A 2-year prospective study of 2- to 6-year-old preschoolers revealed that MEE, diagnosed via monthly otoscopy and tympanometry
, occurred at least once in 53% of the children in the first year and in 61% of the children in the second year.
The guidelines were not written to apply to infants younger than 6 months, and in the youngest infants, tympanometry
and acoustic reflectometry may be less accurate.
Abnormal findings for tympanometry
were considered [+ or -] 100 daPa middle ear peak air pressure, <0.3 mL or >1.7 mL for static compliance.
Derkay said he recommends a physical exam to document the presence of middle ear fluid, plus both audiometry and tympanometry
These include audiometric evaluation (n=126, 99%), head MRI studies (n=78, 62%), tympanometry
(n=67, 54%), ABR (n=55, 43%), complete blood work-up (including thyroid stimulating hormone and vitamin B12 levels) (n=33, 26%), psychoacoustic testing (e.g.,: tinnitus pitch and loudness matching tests) (n=23, 18%), temporal bone CT scan (n=13, 10%), and single positron emission tomography (SPECT) (n=3,2%).
Fiberoptic endoscopy and tympanometry
were performed before and after treatment.
Acoustic immittance test showed A-shaped tympanometry
curves of both ears as well as normal acoustic reflex thresholds of ipsilateral and crossed stapedius muscles.
Surgical success was defined as an intact TM on clinical examination and by tympanometry
testing at the time of the final postoperative assessment.
Otitis media with effusion was diagnosed by otoscopy and confirmed through audiometry and tympanometry
