Objective To explore the diagnostic value of multiplanar reformation of high-resolution computed tomography(HRCT) for congenital ankylotia with other deformity,and improve the recognization of composite otology deformity.Methods The whole clinical,surgical identified data of 82 patients(106 ears) with congenital ankylotia is retrospectively reviewed.61 cases are male and 21 cases are female.The average age is 2.4 years(range from 2 months to 14 years).24 cases are bilateral ankylotia,39 cases are only right ankylotia and 19 cases are only left ankylotia.Most of them are conductive deafness,such as perceptive deafness accompanies inner ear deformity.Results Ankylotia is usually companied complex middle ear deformity,accounting for 72%(76/106),and a low incidence in inner ear deformity is 8%(9/106).Among them,the osseous ankylotia(77 ears) is usually companied the complex middle ear deformity,accounting for 92%(71/77),and inner ear deformity is rare,about 10%(8/77).The incidences of middle ear and the inner ear deformity with membranous atresia(29 ears) are scarce,total accounting for 20%(6/29).Conclusion HRCT multiplanar reformation could be used to observe the anatomical structure of auricle,external auditory canal,middle ear and inner ear in the whole course,has important value in the diagnosis of congenital ankylotia with other deformity.

Objective:To improve the value of multi-slice spiral CT in the diagnosis and treatment of small intestinal lymphomas.Methods:15 patients with small intestinal lymphomas underwent multi-slice CT dynamic enhancement scans, images of axial and reconstructive images were analyzed, patients were respectively diagnosed.Results:11 cases, 3 cases and 1 case located ileum, jejunum, duodenum respectively. Appearances of small intestinal lymphoma are categorized into focal node, soakage and polypus. Focal node, soakage and polypus. were 5, 6 and 2 cases respectively.Conclusion:MSCT dynamic scan have distinctive superiority in diagnosis and treatment of the small intestinal lymphoma.
