Stapedial Artery

AbstractPersistence of the stapedial artery is rare. A case is presented in which the stapedial artery was found over the footplate during stapes surgery. The technical problems encountered are discussed.A wire prosthesis has previously been used in the presence of a persistent stapedial artery and we describe the use of an all Teflon prosthesis.A subsequent CT scan demonstrated the vessel in the middle ear.An outline of the embryology of the stapedial artery is given and the literature reviewed.

Plate Location

The license plate location method is the key technology of license plate recognition system, new algorithm is proposed based on LOG operator detecting edge of License Plate Location. First, a large number of color plate images are preprocessed to remove the background interference information, and then rough location of license plate based on block method, search area of plate will be greatly reduced and accurate positioning the plate will be realized by LOG operator combined with projection method. Static license plate image positioning by simulation and analysis show that the method has high accuracy in license plate location.

Meningeal Artery

Persistence of the stapedial artery is a rare event. Fewer than 30 cases have been reported since the discovery of this artery in 1836. We carried out a histopathologic study on three temporal bones from two patients who had this anomaly, and were able to trace the full course of the artery. In two specimens a large stapedial artery persisted and substituted for the middle meningeal artery. In the third, a small, persistent stapedial artery ended in the arterial plexus surrounding the facial nerve. Persistence is discussed in terms of embryogenesis, developmental theories, histologic findings, and clinical significance. The material suggests that the stapedial artery can persist to varying degrees
