Primary | Assessment of middle ear pressure | This was performed using Tympanometer that measures the air pressure in the middle ear to obtain Tympanogram which is a graphic representation of how the eardrum moves in response to the air pressure in the ear canal. Tympanometry was performed using a AT235 tympanometer with a 226-Hz probe frequency. It was calibrated to ANSI standards (American National Standards Institute,1987).
The normal middle-ear pressure values for children are +50 daPa to -200 daPa. |
up to one year of age | |
Primary | Assessment of middle ear compliance | This was performed using Tympanometer.
The patients' tympanometric results were classified into three types: Type A: Static compliance greater than 0.1 ml and the point of greatest compliance is at approximately 0 daPa; the curve is shown by a large, inverted V. In a "type A" curve, the peak compliance occurs at or near atmospheric pressure indicating normal pressure within the middle ear. Type B: The point of greatest compliance cannot be found, and the curve is shown by a flat curve (no peak). This is indicative of non-compressible fluid within the middle ear space (otitis media), tympanic membrane perforation, or debris within the external ear canal. Type C: Static compliance greater than or equal to 0.2 ml, and the peak compliance is significantly below zero (usually less than -200), indicating negative pressure (sub-atmospheric) within the middle ear space. Type A tympanograms were classified as normal, but types B and C were considered abnormal |

Primary | Assessment of hearing quality | Audiometric screening will be performed using Auditory brainstem response (ABR) conducted under natural sleep as far as possible. ABR can provide information about the softest level of sound the ear can hear. It is traditionally used to determine the degree of hearing loss in pediatrics.
ABR test uses electrodes attached with adhesive to the baby's scalp. While the baby is sleeping, clicking sounds were made through headphones over the baby's ears. The test measures the brain's activity in response to the sounds. Hearing level thresholds as estimated by ABR are categorized as normal (25 - 35 dB nHL), mild (35 - 45 dB nHL), moderate (45 - 65 dB nHL), severe (65 - 90 dB nHL), and profound (90 dB nHL) hearing loss. |
