OBJECTIVE
To explore the correlation between childhood obstructive sleep apnea-hypopnea syndrome and tympanogram.

METHOD
A prospective clinical study was carried out. Polysomnography and tympanogram were analyzed in 72 cases.

RESULT
Among the 144 ears 37 ears had type C or B tympanogram. There was no correlation between tympanogram and LSaO2. It was found correlation between tympanogram and AHI (P < 0.05).

CONCLUSION
Hypoxemia may affect middle-ear function. It was necessary to do the examination of acoustic impedance routinely in children with moderate and severe OSAHS.
