Anatomy from the Inside Out

The upper aerodigestive tract is a complex region of human anatomy owing to the diverse and dynamic physiologic functions that it provides. A thorough anatomic understanding provides the basis for comprehending the physiology and pathophysiology of various neurologic laryngeal and pharyngeal diseases. As laryngoscopy, both flexible and direct, has become more common and produces higher resolution images, the importance of maintaining an in-depth understanding of laryngeal anatomy has increased significantly. We discuss pharyngeal and laryngeal anatomy from the luminal perspective to aid in interpreting the laryngoscopic exam. Anatomy is reviewed in a stepwise fashion beginning with the laryngeal skeleton and expanding to include all laryngeal structures. Particular detail is provided for vascular structures in planning microlaryngeal surgery and office-based procedures.

上呼吸消化道是人体解剖学中一个复杂的区域，因为它具有多样且动态的生理功能。透彻的解剖学理解为理解各种喉部和咽部神经疾病的生理学及病理生理学提供了基础。随着可弯曲喉镜和直接喉镜检查变得更加普遍，并能产生更高分辨率的图像，深入理解喉部解剖学的重要性显著增加。我们从管腔的角度讨论咽部和喉部解剖学，以帮助解读喉镜检查。解剖学以逐步的方式进行回顾，从喉部骨骼开始，扩展到包括所有喉部结构。在规划显微喉镜手术和门诊手术时，对血管结构提供了特别详细的介绍。
