Abstract

Clinical issue: The anatomy of the petrous bone is very complex, particularly due to the many important nervous, vascular and muscular structures that run through it, as well as the protection of hearing and balance organs. Anatomical standard variants complicate radiological interpretation, can imitate pathologies, and present surgeons with enormous challenges during surgical procedures.

Standard radiological methods: Morphological imaging-based diagnostics for detecting normal anatomical variants of the petrous bone include computed tomography (CT) and/or magnetic resonance imaging (MRI). The patient's precise history of existing symptoms or previous surgery also plays a role in the assessment of the findings. Radiologists must be aware that some anatomical standard variants can mimic pathology, and therefore there is a risk of misinterpretation. The imaging helps surgeons facilitating preoperative planning and identification of possible complications.

Conclusion: Precise radiological knowledge of the complex anatomical relationships of the petrous bone is crucial in routine radiological and neuroradiological practice. A detailed description of existing anatomical standard variants enables colleagues in surgical disciplines such as otolaryngology and neurosurgery to efficiently prepare the procedures and assess possible complications.

[岩骨的解剖变异]。
临床问题:岩质骨的解剖结构非常复杂,特别是由于许多重要的神经、血管和肌肉结构贯穿其中,以及保护听力和平衡器官。解剖标准变异使放射学解释复杂化,可以模仿病理,并在手术过程中给外科医生带来巨大的挑战。标准放射学方法:用于检测石质骨正常解剖变异的基于形态学成像的诊断包括计算机断层扫描(CT)和/或磁共振成像(MRI)。患者现有症状的确切病史或既往手术也在评估结果中起作用。放射科医生必须意识到,一些解剖标准变异可以模仿病理,因此存在误解的风险。成像帮助外科医生促进术前计划和识别可能的并发症。结论:在常规放射学和神经放射学实践中,准确掌握岩骨复杂解剖关系的放射学知识至关重要。现有解剖标准变异的详细描述使耳鼻喉科和神经外科等外科学科的同事能够有效地准备手术并评估可能的并发症。
