年齢別にみた小児中耳炎の臨床観察

A CLINICAL OBSERVATION ON AGE DIFFERENCE IN THE MORBIDITY WITH OTITIS MEDIA AMONG THE INFANCY AND CHILDREN

　戦後抗生剤の登場により，小児急性中耳炎の合併症は激減し，耳科臨床にとつてさほど問題にならなくなつたかにみえる。しかし日常，子供の中耳炎に接しているわれわれ開業医にとつてはもつとも悩まされる疾患の1つである。

　種々の抗生剤に抗し，遷延し，再発する乳幼児の急性中耳炎，難聴を主訴とする中耳カタル。いずれもその治療法に決め手を欠く。しかもこれらの治療に際し，急性像の消退で事成れりとすることの愚かさは耳科医の誰もが感ずることであり，もし後に難聴をのこした場合，言葉の習得や就学の問題などと，きわめて大きな悩みを親にも子にも与えることになる。

　A survey on the total number of otitis media that had occurred in the City of Saga during one year of 1972, among infants and children whose ages ranging from 0 to 12 inclusive, was attempted by acquiring reports from all 4 sourses of treatment centers, the City's ENT practitioners.

　There were 913 patients with 1,167 ears involved with otitis media. The morbidity was low among those of 0 age but began to be increased as the infants attain the age 1 and reaching the peak at the ages 3 to 5. This number again began to be decreased at about the age 6. The highest number of morbidity was found among the 3 year olds and the highest number of secretory type was found among the 5 year olds.

　The duration of treatment requirement was the longest among the 0 ages, along with the largest number of recurrences but the latter had a tendency to be decreased as the infants grew older.
