ABSTRACT
Objective To evalute the value of spiral CT in diagnosis and treatment of chronic suppurative otitis media.Methods Sixty-five cases including seventy-nine ears underwent the direct axial plane and coronal multiplanar reformation and three-dimensional reconstruction of auditory ossicular chain in chronic suppurative otitis media spiral CT imaging of temporal bone. Results The direct axial plane and coronal multiplanar reformation in diagnosing of the chronic suppurativeotitis media were correspondent,but in showing of the most middle ear structure were difference. Three-dimensional images was superior to axial and coronal MPR images in showing of the change of malleus and incus,the contrary situation in showing stapes. Only 3D image may not select application for definition.The rate of agreement between spiral CT diagnosis by combination of three different imaging methods and definition of chronic suppurative otitis media and operative findings(89.9%~97.5%) were higher, false positive rate(2.9%~6.0%) and false negative rate(0~14.6%) of the CT diagnosis were lower.Conclusion Combination of three different imaging methods(axial images, coronal MPR images and three-dimensional images of the ossicular chain) can improve the value of the spiral CT diagnosis and therapy of chronic otitis media.
