Abstract

Objective. To investigate the application of multislice spiral CT in volume reconstruction of congenital microtia. Methods. Sixty patients who underwent auricle reconstruction in Otolaryngology Hospital of our hospital from April 2020 to April 2021 were selected. All patients had no mental disorders and normal cognitive ability and volunteered to participate in this study. Multislice spiral CT was used to evaluate the diagnostic accuracy of multislice spiral CT by scanning the morphology of the ossicular chain and the bone destruction of the selected patients. Results. MSCT can clearly display the structure of ear. Conclusion. MSCT can clearly reflect the external ear and the structure of the ear in patients with congenital microtia and distinguish the different types of patients obviously. Multiplane reconstruction and volume reconstruction can clearly display the fine structure of the patient’s ear, which has important reference value for surgery.

Highlights

Congenital microtia, known as microtia, is characterized by symptoms such as severe underdevelopment of auricle, atresia of external auditory canal, and impairment of hearing ability
Congenital microtia is a kind of congenital malformation with unknown causes, which is characterized by congenital auricle dysplasia, often accompanied by external auditory canal atresia, middle ear, and maxillofacial malformations
High-resolution CT (HRCT) and multislice spiral CT (MSCT) three-dimensional reconstruction techniques such as surface shadow are used for normal structures and diseases such as ossicular chain and inner auricular labyrinth maximum/minimum intensity projection (MIP/MINIP), maximum/minimum intensity projection (SSD), multiplanar reconstruction (MPR), virtual endoscopy (VE), and other studies have been reported in recent years

Summary

Introduction

Congenital microtia, known as microtia, is characterized by symptoms such as severe underdevelopment of auricle, atresia of external auditory canal, and impairment of hearing ability. Congenital microtia is a kind of congenital malformation with unknown causes, which is characterized by congenital auricle dysplasia, often accompanied by external auditory canal atresia, middle ear, and maxillofacial malformations. High-resolution CT (HRCT) and multislice spiral CT (MSCT) three-dimensional reconstruction techniques such as surface shadow are used for normal structures and diseases such as ossicular chain and inner auricular labyrinth maximum/minimum intensity projection (MIP/MINIP), maximum/minimum intensity projection (SSD), multiplanar reconstruction (MPR), virtual endoscopy (VE), and other studies have been reported in recent years. E purpose of this study is to further study the application value of VR in displaying the anatomical structures of normal middle ear and inner ear, as well as the surface and auditory nerve in the internal auditory canal, and to compare VR with other postprocessing techniques to evaluate the superiority of VR Compared with MIP and SSD, which only use 10% of volume data after editing, the images obtained are more realistic, three-dimensional, and clear. e purpose of this study is to further study the application value of VR in displaying the anatomical structures of normal middle ear and inner ear, as well as the surface and auditory nerve in the internal auditory canal, and to compare VR with other postprocessing techniques to evaluate the superiority of VR
