Adenoidectomy with myringotomy and tympanostomy tube versus adenoidectomy with myringotomy in treatment of otitis media with effusion in 5-7 years old children

الملخص EN

Background : Adenoiditis is a common cause of otitis media with effusion (OME) in children & perhaps OME is one of the most common diseases leads to hearing impairment in children with subsequent impairment of speech development & learning difficulties , however, treatment remains controversial.

Objectives: To evaluate if there is a significant advantage of tympanostomy tube insertion in association with adenoidectomy over adenoidectomy in association with myringotomy alone in treatment of children with OME Type of the study : This is a prospective study.

Patients & methods : The study consisted from 63 children diagnosed as cases of bilateral OME & variable degrees of adenoid hypertrophy.

The patients were divided randomly into two groups, group A (32) were subjected to adenoidectomy & myringotomy with tympanostomy tube insertion & group B (31) were subjected to adenoidectomy & myringotomy alone.

Pure tone hearing threshold was measured preoperatively & at the 3rd month and 6th month postoperatively.

Statistical analysis is done to compare the means of pure tone hearing threshold between group A & B.

Results : The mean pure tone hearing threshold preoperatively in group A was 28.3 dB, while it was 27.9 dB in group B.

Three and six months postoperatively the means in group A were 13.2 dB and 6.8 dB respectively, while the means were 19.4 dB and 13.6 dB respectively in group B.

Statistical analysis showed statistically significant difference between the means of pure tone hearing thresholds in both groups during the whole follow up period (P value less than 0.05).

Conclusion: There is statistically significant advantage of tympanostomy tube insertion in association with adenoidectomy compared to adenoidectomy with myringotomy alone in treatment of OME in term of hearing level.
