耳輪脚基部の先天性耳瘻孔の摘出法

抄録

The infected fistula auris congenita at the base of crus helicis makes its total removal difficult through the preauricular approach because of the location of the main lesion. The fistula sinus is usually located deep behind the auricle. Therefore, it is easier to extirpate the entire lesion through the retroauricular approach than the preauricular approach.
The retroauricular approach enables a wider operative field and makes the lesion free easier from the surrounding tissues.
The author describes a detailed technique of the retroauricular approach for the infected fistula auris congenita at the base of crus helicis.
