Aus Dornheim Anatomy
The esophageal orifice refers to the uppermost and narrowest part (constrictio pharyngooesophagealis). This is located in the pars cervicalis at the level of the cricoid cartilage of the larynx and measures approximately 14 millimeters in maximum diameter. Starting from the cricoid cartilage of the larynx, muscles surround the esophageal orifice and close it in the form of a sphincter, which is closed at rest.
