Abstract: This study was designed to improve CT and magnetic resonance imaging (MRI) in ophthalmologic and otorhinolaryngologic diseases. We systemically investigated the relationship between the ophthalmologic and otorhinolaryngologic anatomic structure and physiology, the anatomic variation and disease, and the disease and imaging sign. A system of CT and MRI examination methods in the ophthalmology and otorhinolaryngology was established. Based on CT and magnetic resonance imaging database of ophthalmologic and otorhinolaryngologic diseases, CT and MRI diagnostic system was established and CT and MRI features of common disease was revealed. We proposed and confirmed the mechanism that the defect of bony wall of the vessel within the temporal bone was responsible for pulsatile tinnitus. The neural-muscle distribution hypothesis for congenital complex strabismus was tested. In a word, the serial study promoted recognition, diagnosis, and treatment of ophthalmologic and otorhinolaryngologic diseases.
