石膏印象法に依る合成樹脂使用の隆鼻術新法

　緒言

　象牙隆鼻術は1918年ベルリン市の整形外科教授ヨゼフ氏が創始せしより余り改良せられることなく今日に至つた．日本に於ては昭和3年（1928年）初めて西端教授が紹介し，又石井氏は多数例を報告している．此処に述べんとする本法は日本耳鼻咽喉科全書第4卷の象牙隆鼻術法に改変を加えたものでその材料として現今肺充填に使用され生物学的に比較的害なしと考えられる合成樹脂を使用した点とその挿入物は彫刻法に依らずして印象法を採用し形？の適合性を理想的にした点で此処に報告する次第である．

Kokura says in reference to aesthetic nasal plastic surgery, the method employed heretofore calls for inserts which require expert technic of painstaking and scrupulous carving. These time-consuming and expert elements may be totally eliminated in the present method which deals with obtaining proper casts of plastic material from waxen Moulds. Initial step in the process is obtaining plaster of paris facial cast in order to construct the facial mask. The dorsal nasal contour is now corrected on this mask by use of softly moulten wax to the desired aesthefic effect and, which is then allowed to set by cooling. Replica in plastic material obtained from the waxen mould is the insert to be used in the corrective operation. Advantages of the new method over the old are as follows : (1) The insert fits more snuggly and equally over the surface of nasal bone ; (2) Technically easier to make and allows any number to be made as readily as making one and a greater choice of selecting the most suitable at the time of opera-tion; (3) More economical in material cost; (4) More scientific in application in which the ele-ment of specialized technic is eliminated; (5) Of what the facial contour was before the operation could be easily preserved in case of later need for reference.
