소아 급성 중이염 치유의 고실도에 의한 판정
Published Online: May 31, 2020
ABSTRACT
Acute otitis media(AOM) is common health problem among infants and children throughout the world. The goal in treating AOM is to relieve the symptoms as ear pain and fever, to expedite the resolution of middle ear fluid and accompanying conductive hearing loss, and to minimize recurrence, complications and sequelae.
There are many definitions of successful treatment of AOM. Authors used tympanometric results as successful treatment of AOM in 32 patients(42 ears). Tympanometry can be performed in almost all patients and is an object test that does not require voluntary patient response. And authors compared the results of the single frequency, single component tympanometry (conventional tympanometry) and those of the multifrequency multicomponent tympanometry.
The results were obtained as follows:
Tympanographic findings at initial visit were type A in 4 ears, type B in 33 ears and type C in 5 ears among 42 ears.
The cure rate was 70.0% (28/40 ears) based on the only clinical findings and 64.3% (A type = 18/28 ears) in single frequency, single component tympanogram. Of the 18 ears which were recovered to A type on single frequency, single component tympanometry, 9 ears were recovered within 7 days, 15 ears were within 2 weeks, 1 ear was recovered at 3 weeks, and remaining 2 ears were revovered at 4 weeks after treatment.
The accordance rate between the results of single frequency, single component tympanometry and those of multifrequency, multicomponent tympanometry was 61.1%.
These results suggest that multifrequency, multicomponent tympanometry may be more sensitive than single frequency, single component tympanometry for detecting AOM sequelae, and middle ear pathology may persist longer than conventional tympanometry results and clinical findings suggest.
