“…A recent study reported three-dimensional computed tomography (3D-CT) reconstruction as a potential method for imaging different sorts of middle ear implants 12 ; in this regard, the importance of 3D-CT lies mainly in verifying the right position postoperatively. Such measurements seem to be more valuable in cases of passive middle ear prostheses and not in MET and Carina implantations, which can easily be identified with the use of two-dimensional HRCT.…”

“…With the rapid advancement of computer technology, multi-slice spiral computed tomography (MSCT) is now widely applied in clinical practice to display the fine structures and determine the severities of the malformations of the middle ear with high clarity [12]. e application of MSCT and image postprocessing functions, such as multiplanar reconstruction (MPR) and curved planar reconstruction (CPR) images, has greatly improved the detection rate and accuracy of the diagnosis of middle ear malformations [13,14]. MSCT with image postprocessing can facilitate the clinicians to choose the suitable treatment strategies and surgical methods and effectively prevent iatrogenic facioplegia induced by intraoperative damage [15].…”

Background. Simple congenital middle ear malformations (SCMEMs) are a group of congenital ear malformations. The study aims to analyze the multi-slice spiral computer tomography (MSCT) manifestations of normal ears and SCMEM ears. Objectives. This study aimed to investigate the MSCT manifestations of normal ears and SCMEM ears and to evaluate the relationship between the SCMEM and the tympanic segment of the FNC pathway. Methods. This was a retrospective case-control study. Patients who were diagnosed with SCMEM were included in the SCMEM group. Patients with vertigo, pulsatile tinnitus, or other symptoms were included in the control group. MSCT examination and image processing of the ossicular chain, facial nerve canal, and related structures were performed and compared between the two groups. Results. There were 94 cases in the SCMEM group (125 ears) and 97 cases in the control group (190 ears). Sixty-three cases (67.0%) were unilateral malformations (36 right ears and 27 left ears). MSCT showed congenital stapes malformation in 107 ears (85.6%) and incus long process malformation in 84 ears (67.2%). Among these, simple stapes malformations were found in 41 ears (32.8%), simple incus malformation in 18 ears (14.4%), and stapes malformation complicated with incus malformation in 66 ears (52.8%). The distance between the facial nerve and lateral semicircular canal (FNC-LSC) in the SCMEM group was 1.30 ± 0.64 mm compared to 0.79 ± 0.11 mm in the control group (P < 0.001), and the distance between facial nerve canal and oval window (FNC-OW) was 0.67 ± 0.53 mm in the SCMEM group and 1.13 ± 0.18 mm in the control group (P < 0.001). Conclusion. SCMEM occurred mainly in ossicular chain abnormalities. MSCT clearly showed the slight structural changes in the middle ear and provided an accurate basis for preoperative diagnosis.
