Skull temporal bone is a pair of non-planning skull, can be divided into scales Ministry of papillae (Ministry of rock) and drum, the temporal bone rock can be seen as a triangular pyramid, followed by a bony protrusion below, known as the styloid process, conventional stem Projection before and after the projection method, the operation is more complicated, often can not get satisfactory images, after many years of practice, summed up a new method of projection is now as follows: 1. Film: 13 × 18 (5 × 7) Direct release. 2. Location: The patient may take a stand, sitting, supine position will be placed in the outer ear on the center of the cartridge center, the face turned to be detected so that the head of the sagittal plane and the cartridge at 80 ~ 85 angle ° mandibular slightly tilted, so listen 眦Line and cassette into a 95 ~ 100 ° angle.
