ABSTRACT
@#BACKGROUND. Otitis media (OM) is any inflammation of the middle ear. It is very common in children. The purpose of Survey is to analyzing result that insertion of tympanostopmy tube treatment for children who had otitis media. METHOD. The study covers total 482 tympanostomy surgery cases conducted, between 2013-2015, at ENT Surgery Department, National Center for Child and Maternal Health. Titanium tube had been placed for the patients with either adhesive otitis media and otitis media with effusion. In order to evaluate surgery results, follow up examinations were carried out in 2 weeks, 1, 3 and 6 months using otoscopy, audiometer, ABR and ASSR test. RESULTS. Most of the children (82.4%) in whom a ventilating tube have been placed in tympanic membrane had exudative otitis and the remaining (17.6%) children had adhesive otitis. In means of age group, children with 0-2 years, 3-4 years, 5-6 years, 7 and more were, 39.9% (n=173), 42.7% (n=206), 15.6% (n=75) and 5.8% (n=28) respectively. After the tympanostomy surgery tympanic membrane color gets better, turns pearl grey, fluctuation improves, membrane cavity pressure lowers to -50daPa and hearing status ranged 20.4-5.4dB which allows the patient to continue normal speech development. CONCLUSION. Among 482 patients whom involved surgical procedure of Insertion of tympanostomy tube treatment last 3 years in Department of Pediatric Otolaryngologists in Maternal and Child Health of Mongolia and otitis media with effusion and adhesive otitis media type were occurred 30% to 40% from above cases. After tube placement tympanic membrane movement improved and color of tympanic membrane is getting pearl-grey and middle ear pressure decreasing until to 50daPa and children hearing range changed 20.4 to 5.4 db. So we could prevent these children suffer speech disorder .
