The effects of childhood otitis media on the acoustic reflex threshold at age 15

[Influence of tympanic membrane changes on immittance and extended frequency audiometric findings]

INTRODUCTION

The aim of the study is to analyze the relationship between otoscopic tympanic membrane abnormalities, results of impedanace and extended-high-frequency audiometry in subjects with history of treatment of secretory otitis media (SOM) and ventilation tube insertion.

MATERIAL AND METHODS

97 subjects treated because of SOM were examined in years 1999-2000. Videootoscopic examinations, extended-high-frequency audiometry and tympanometry with ispilateral acoustic reflex were performed in each patient. The results were analysed in three groups: no otoscopic abnormalities (BZO), retraction pockets (KR) and atrophy and myringosclerosis (AM). The results were compared to otologicaly healthy control group in the same age.

RESULTS

The most common tympanic membrane abnormality were focal atrophy (64.7%) of ears and myringosclerosis (37.2%). Mean pure-tone audiometric threshold were significantly higher in groups KR and AM than in control and BZO groups. Low degree of positive correlation was found between the presence of myringosclerosis and atrophy and audiometric thresholds above 1 kHz. No such correlation was observed with the presence of retraction pockets. In the BZO group middle ear admittance was observed significantly higher than in control group. The absent ipsilateral stapedial reflex was observed in 10.8% ears in BZO group, 16.9% in AM and 33.3% in KR. No correlation was found between the parameters of tympanometric evaluation and results of extended-high-frequency audiometry.

CONCLUSIONS

In ears treated because of SOM with ventilation tube insertion the middle ear compliance is higher. In the presence of myringosclerosis and atrophy higher audiometric thresholds are observed. Tympanic membrane abnormalities have been more clearly indicated by the absent ipsilateral stapedial reflex than tympanometry.

No Negative Outcomes of Childhood Middle Ear Disease in Adulthood

OBJECTIVES/HYPOTHESIS

To test the hypothesis that childhood middle-ear disease may have disadvantageous long-term psychosocial consequences in adulthood.

STUDY DESIGN

Prospective, longitudinal study of a general-population birth cohort.

METHODS

One thousand thirty-seven people born in 1972/73 were studied from birth to age 26 when 1,019 (96% of survivors) were followed up. Childhood otitis media was assessed, and effects of it have previously been observed in childhood and adolescence. We considered outcome measures that were plausible adult counterparts of the childhood constructs shown to be impaired by otitis media: socioeconomic status, employment status, educational outcomes, personality, mental health, antisocial and criminal behavior, and subjective ratings of personal health (SF-36).

RESULTS

No outcome measure was predicted by severity of childhood otitis media.

CONCLUSIONS

Adult psychological and socioeconomic outcomes are not related to childhood otitis media when appropriate treatment is available.
