AHORIZONTAL supra-auricular incision above the root of the auricle with a superior approach to the mastoid antrum, middle ear, and labyrinth will be described (Fig. 1). The temporary displacement of the auricle downward and forward requisite for operations upon the middle ear can be obtained by this incision through the scalp at the level of the upper border of the root or attachment of the auricle to the temporal bone.
The auricle with its root is superimposed upon the temporal bone as a shield, or carapace. The root of the auricle is a direct lateral relation of the middle ear, attic, and mastoid antrum and of the upper portion of the mastoid process. Horizontal lines drawn through a section of the ear at the level of the tegmen tympani and tegmen mastoideum (Fig. 2) are in immediate caudal relationship to a horizontal line through the level of the upper border
