MY METHOD OF OPERATION FOR TREATMENT OF CHRONIC SINUSITIS

　Ⅰ．緒言

　慢性副鼻腔炎の手術方法について西端^1）の綜説にもあるごとくその目的により各種の方法が発表されてはいるが，私は手術侵襲を少なくし，かつ副損傷を避けることを主目的に，16年余手術方法の工夫改良に努力を重ね，現在ほぼ満足すべき方法に到達したので，ここにその概略を私見を加えて報告し，諸賢のご批判を仰ぐ次第である。

　The author describes his method of operation for treatment of chronic sinusitis in which the tissue injury of the procedure is minimized to a large extent.

　The operation is begun by placing a vertical incision along the ligamentum labialis superior. From this point a horizontal incision is placed along the labiogingival border. The periosteal separation is carried upward to expose the pyriform aperture. A necessary surgical correction is carried within the nasal cavity; the mucous membrane of the inferior meatus is separated from the lateral nasal wall to expose the anterior portion of the inferior turbinate which is, now, separated from its base crista chonchalis. The maxillary sinus is now exposed by removal of the lateral nasal wall; a special care is taken to avoid any in jury to the nasal lacrymal duct.

　The operation is carried to the upper region of the nasal cavity by removal of the uncinate process. The sulcus ethmoidalis of the os nasale is craped down. The bony separation betweenthe recessus supraorbitalis and the frontal sinus is bitten away to facilitate a better drainage of the latter. However, the mucous membrane of the posterior wall of the frontal sinus and the roof of the ethmoid sinus is by all means preserved. Finally, the sphenoid sinus is exposed by removal of the anterior wall.
