Int Tinnitus J. 2022 Dec 1;26(2):95-100. doi: 10.5935/0946-5448.20220014.
Tinnitus is commonly depicted as a ringing within the ears, but it can sound like roaring, clicking, hissing, or buzzing. It is a symptom that shows something is wrong in the auditory system, which includes the sound-related nerve that interfaces the inward ear to the brain, and the parts of the brain that handle sound. Generally, the causes of tinnitus include: Otologic causes, Neurologic causes, temporomandibular joint, and masticatory muscle disorders. Causes of tinnitus can be diagnosed with CT and CBCT. A CT scan or computed tomography scan is a medical imaging technique used in radiology that can obtain detailed internal images of the brain and CBCT is a developing imaging technique designed to provide relatively low-dose high-spatial-resolution visualization of highcontrast structures in the head and neck and other anatomic areas. CBCT has a lower radiation dose, shorter imaging time, and better resolution than CT. This chapter reviews etiology of tinnitus on CT and CBCT.
耳鸣通常被描述为耳内有铃声，但也可能听起来像轰鸣、咔嗒声、嘶嘶声或嗡嗡声。它是一种症状，表明听觉系统存在问题，听觉系统包括将内耳与大脑连接起来的与声音相关的神经以及大脑中处理声音的部分。一般来说，耳鸣的原因包括：耳科原因、神经学原因、颞下颌关节和咀嚼肌紊乱。耳鸣的病因可以通过CT和CBCT进行诊断。CT扫描或计算机断层扫描是放射学中使用的一种医学成像技术，可以获得大脑的详细内部图像，而CBCT是一种正在发展的成像技术，旨在对头颈部和其他解剖区域的高对比度结构提供相对低剂量的高空间分辨率可视化。与CT相比，CBCT的辐射剂量更低、成像时间更短且分辨率更高。本章回顾了CT和CBCT上耳鸣的病因。
