歯性上顎洞炎の臨床的研究（綜括的観察）

　Ⅰ緒言

　曩に昭和25年度の第51回総会に歯性上顎洞炎30例の臨床的観察に就て報告し，それに関しては，既に誌上にも発表した通りであるが，其後約4年間に更に90例の典型的な歯性上顎洞炎の症例を経験することが出来たので，これに就て今回は綜括的観察を試み此処に報告して聊か参考の資料に供したいと思う。

HORIGUCHI and MIURA report their ob-servations on 90 cases of maxillary sinusitis that are dental in origin which represented about 4-6 percent of the total number sinu-sitis seen. The disease is recognized in younger adults in their 20s whose complaint is malodorous nasal discharge. The causa-tive tooth is generally the first molar which when extracted will often reveal a passage of continuity from the socket into the sinus cavity whence the discharge may be seen to beexuding. Cases of this nature that show chonicity would not only show a good response to operative treatment but short of which rarely recover; in acute cases recovery may be attained by more conservative methods.Percentages of complete recovery following operative treatment are greater here than co-mpared to sinusitis of various other causes.
