Abstract
SUMMARY AND CONCLUSION
Otitis media with effusion is an inflammatory disorder of the middle ear; it is one of the commonest chronic otological conditions seen in children. Adenoidectomy is being increasingly used for the treatment of OME because recent studies have confirmed its effectiveness.
The present study is a prospective one to evaluate the hearing results of cases of otitis media with effusion treated by adenoidectomy alone with those treated by adenoidectomy plus ventilation tubes and to evaluate the rate of complications of ventilation tubes.
This study was conducted at the Otorhinolaryngology outpatient clinic of Beni-Suef University Hospital during the period between January 2017 to February 2018 and included 40 patients with otitis media with effusion (25 males and 15 females). Patients were divided to two groups: group (A): Included 20 patients subjected to Adenoidectomy with insertion of ventilation tubes. group (B): Included 20 patients subjected to Adenoidectomy without insertion of ventilation tubes.
The results of our study showed that:
Adenoidectomy improved significantly 1 year postoperative pure tone audiometry of both ears by increasing number of normal PTA cases and decreasing number of mild CHL cases.
Eustachian tube functions at 1 month postoperatively after tube extrusion in Adenoidectomy with tube patients (group I). This result was statistically significant (p< 0.01).
Also, in Adenoidectomy with tube group, PTA after tube extrusion was significantly (P< 0.01) improved and the majority of cases had normal PTA in both ears. Also, Tympanogram was as significantly (P< 0.01) improved after tube extrusion in both ears.
The results revealed that normal cases in postoperative pure tone audiometry were significantly higher in group I compared to group II.
from the previous results it can be concluded that:
OME is an inflammatory disorder of the middle ear which leads to hearing impairment in children. Adenoidectomy improved significantly postoperative PTA. Adenoidectomy with ventilation tubes insertion significantly improved postoperative Eustachian tube function and also improved significantly postoperative PTA and Tympanogram. Both forms of adenoidectomy are effective in managing OME, but adenoidectomy with ventilation tubes is better than Adenoidectomy only in improving pure tone audiometry and is effective in clearing middle ear effusion and causing hearing improvement of children with OME. Also, it can be regarded as a useful management option in children with otitis media with effusion. Further research is needed with larger number of cases and long follow up period to support the present findings.
