Evaluation on the virtual CT endotoscope for the diagnosis of ossicular chain lesions accompanied with congenital aural deformity
摘要
Abstract
Objective To investigate the value of virtual CT endotoscope for the diagnosis of ossicular chain lesions accompanied with congenital aural deformity. Methods Thirty cases (43 ears) with congenital aural deformity were undergone high resolution CT scanning to collect the original image data from the focus in middle ear, followed by 3-dimensional reconstruction to process these images for evaluating the possibly presented lesions with the ossicular chain. Then, a comparative analysis was made on the virtual CT endotoscopic findings in a correlative consideration with that actually found during the operation on the ossicular chain lesions. Results 30 ears were aural atresia which contained malleus hypoplasia in 18 ears, incus hypoplasia in 13 ears, malleus and incus absence in 3 ears, stapes abnormity in 13 ears, stapes absence in 4 ears, fusion of malleoincudal joint in 20 ears, fusion of incudostapedial joint in 7 ears and incudostapedial joint connected with soft tissue in 2 ears. 13ears were simple ossicular deformity which contained caput mallei and incus embedded in upper inner wall of atticus in 2 ears, caput mallei connected with upper paries tympanica in 3 ears, distal end of handle of malleus connected with tpympanic ring in 1 ear, crus longum incudis hypoplasia in 4 ears, stapes aberrance in 1 ear, structure suprastapedialis absence in 3 ears,vestibular window atresia in 1 ear, structure suprastapedialis abnormity in 2ears. Thirty-one ears were treated by surgeries, The results of preoperative Virtual CT endoscopy were basically consistent with the surgical exploration. Conclusions Virtual CT endotoscope can clearly display the figure of ossicular chain and its spatial relationship with other structures in the middle ear and provide more detailed information to improve the preoperative diagnostic levels for ossicular chain lesions and to prepare a more practical strategy for surgical treatment on congenital aural deformity.关键词
