Fibrous membrane connecting the cricoid cartilage to the hyoid bone. No such structure exists anatomically - common error for cricothyroid membrane.
Full Definition
The term 'cricohyoid membrane' represents a common anatomical error that appears in medical literature and clinical documentation. No such membrane exists between the cricoid cartilage and hyoid bone. This confusion typically arises from misunderstanding of neck anatomy and incorrect terminology usage. The actual structures in this region include the cricothyroid membrane (connecting cricoid and thyroid cartilages) and the thyrohyoid membrane (connecting thyroid cartilage and hyoid bone). In head and neck surgical documentation, proper anatomical terminology is crucial for accurate communication and patient safety, particularly when describing emergency airway procedures or surgical approaches.
Usage
