Sažetak
The objective was to determine the range of hearing improvement (in dB) post ventilation
tube insertion in children with chronic otitis media with effusion (COME), and whether there
was a difference in hearing improvement between age groups and genders. This study also investigated
whether there was a difference in the mean hearing improvement between the left and right ear, how
many months passed before recovery of eustachian tube function, and how long the aeration of the
middle ear lasted. The children included in the study were between six and twelve years of age, diagnosed
with COME by audiological processing (type B tympanometric recording and conductive hearing loss
up to 40 dB on pure tone audiometry) and underwent surgical insertion of ventilation tubes in both
ears. Patient data included preoperative tympanometric records, preoperative and postoperative tone
audiometry findings, tubometry findings 6 and 10 months after insertion of ventilation tubes, age and
gender data, and length of time during which the tubes were in place. The mean hearing improvement
of the included patients was 24.2 dB on the right ear and 24.5 dB on the left ear. There was no statistically
significant difference between the left and right ear or between the genders. Older age groups had
a higher mean hearing improvement compared with the younger age group. Younger age groups had a
longer expected period of eustachian tube function recovery, and were expected to have ventilation tubes
inserted for a longer period of time. Treatment with ventilation tube insertion resulted in significant improvement
in hearing in children where previous conservative therapy failed to recover eustachian tube
function and improve hearing. Although children of older age groups had greater preoperative hearing
impairment, the recovery of both eustachian tube function and hearing improvement was faster, and the
mean length of time that the ventilation tubes had to be inserted was shorter.
