Otitis media in children : detection of effusion and influence on hearing

摘要: This study was undertaken to improve the diagnosis of otitis media and investigate possible hearing loss caused by middle ear effusion (MEE) in small children. Temporal development AOM assessed from 250 episodes 184 Sixty-three per cent cases occurred during first week after onset URI, peaking on days 2 5. The children with a history recurrent did not differ that those who had experienced only few AOM. No individual tendency noticed among suffering more than one episode follow-up. Studies symptomatology temporal acute (AOM) upper respiratory tract infection (URI) were based three-month follow-up 857 Symptoms URI compared symptoms complicated same child 138 most important symptom associated earache, relative risk 21.3. Sore throat, night restlessness fever at 3-6 also significantly AOM, risks 3.2, 2.6 1.8, respectively. In 44 under two years age, conjunctival cloudy rhinitis accuracy minitympanometry detecting MEE evaluated 162 finding amount found myringotomy. Minitympanometry proved be an accurate method detect young children, sensitivity specificity values being 79 % 93 cooperative but it no value non-cooperative Minitympanometric examination could performed successfully good cooperation 87 total 206 paediatric outpatient clinic. Impaired mobility tympanic membrane (TM) best sign pneumatic otoscopy 76 75 90 %, influence nitrous oxide (N2O) tested weighting myringotomy general anaesthesia without N2O 39 37 mean weight oxygen-air group group, thus peroperative findings are reliable. To assess quantity quality transient evoked otoacoustic emission (TEOAE) before 185 ears 102 Reduced TEOAEs indicating 83 mucoid 56 non-mucoid effusion, difference statistically significant (p<0.01). A negative correlation between reproducibility TEOAE responses (Spearman rank coefficient r=-0.589, p<0.001). Findings correlated TEOAE. Although parents able predict quite reliably, various duration seems little helping Detection OM may improven Any kind cause which must considered when treating OM.
