(Ducts media with effusion (OMB) causes hearing loss and morbidity in
many children, many theories seek to explain production and presistance
ofilluid in the middle ear, but no single mechanism is solely responsible.
_from these factors is the presistant bacterial antigen and impaired middle
ear immunity. In this study 150 patients diagnosed as having OME divided
into two equal groups. 1st group (grotipA) received medical treatment
and 2nd group (B) prepared directly to surgery (Myringotomy and ventilation
tube insertion), cases with failed medical treatment (An) group from
group (A) were subjected to the same surgery. From group (B) and group
(An) (surgical groups) effusion were collected for culture and antigen detection.
Bacterial growth nearly 52% of group (B) and positive bacterial
antigen detected in (An) and (8) groups was 46.9 - 49.3% respectively. |
