上顎洞内カテーテル挿入による小児慢性副鼻腔炎治療の試み

A TRIAL OF TREATMENT FOR SINUSITIS IN CHILDREN BY CATHETERIZATION INTO THE MAXILLARY SINUS

　I．緒言

　小児副鼻腔炎には一部に自然治癒のみられるものもあるが^1），治療に抵抗するものもみられる。

　小児副鼻腔炎の治療は，病態の把握の困難性，患児の体質・遺伝関係などの素因の関与，自然治癒の可能性を考慮に入れつつ行なうべきである^2）。

　Catheterization from the lateral wall of nasal cavity into the maxillary sinus was performed in 10 cases of sinusitis in children (5 males and 5 females). Through the catheter, irrigation with physiological saline, air inflation, nad flush with antibiotics, were carried out 5 times a day for 5 or 6 days.

　It was evident that anaerobic infection as the etiology of sinusitis were increasing, and blockage of the ostium resulted in the decreased concentration of oxygen, and swelling of the mucosa of the sinus could be shrinked by oxygen flush. Thus in 5 out of 10 cases, oxygen flush of 2 1/min was applied into the maxillary sinus via the catheter for 5 minutes.

　As the results, these treatments were effective in 8 cases and ineffective in 2 cases.
