Clinical Application of HRCT 3D Reconstruction in Cochlear Implantation
Objective To explore the clinical application of high-resolution CT(HRCT)3D reconstruction in cochlear implantation(CI).Methods A total of 60 patients with inner nerve deafness confirmed in the hospital were enrolled between June 2021 and April 2023,all were treated with CI.The patients underwent scans by GE Optima CT680 before and during the surgery.During HRCT scan,3D volume rendering technique(VRT),multi-planar reconstruction(MPR),curved-planar reformation(CPR),oblique-planar recombination(OPR)and maximum intensity projection(MIP)were applied.The cochlear related parameters[linear insertion depth(LID),angular insertion depth,rotation diameter and circumference of cochlear base(A value,R value)]during CI were recorded.The measured results of HRCT(distance from facial nerve to cochlear window,distance from facial nerve to vestibular window,distance from facial nerve recess to cochlear window,distance from facial nerve recess to vestibular window)before and during CI were compared.Results During CI,LID,angular insertion depth,A value and R value were consistent with the value range.There was no significant difference in distance from facial nerve to cochlear window,distance from facial nerve to vestibular window,distance from facial nerve recess to cochlear window or the distance from facial nerve recess to vestibular window before and during CI(P＞0.05).Conclusion HRCT 3D reconstruction can clearly display the anatomical structure of nerve deafness in patients with inner ear malformation,which can provide cochlear parameters during CI,with good clinical application value.
