Review the ct and mri anatomy of the hypopharynx and larynx Correlate the images with the findings at endoscopy
The thorough knowledge ofAnatomyis crucialto read head and neck studiesso we intend to catch up this subject centered on hypopharynx and larynx subsites.
The correlation with the laryngoscopy images add anextra value to understand the Anatomy itself andthe otorhinolaryngologistpoint of view.
so we realizethat the laryngoscopy doesn´t depict the "outer" tissues of the airway,
The approach to this subject from different points of views but...
Findings and procedure details
HYPOPHARYNX The hypopharynx extends from the vallecula to the inferior cricoid carilage (cricopharyngeal muscle).
It consists of three regions: pyriform sinus,
postcricoid area or prharygoesophageal junction and posterior hypopharyngeal wall. The pyriform sinus consists of an invaginaion of the aryepiglottic folds and the thyroid cartilage.
Its inferior tip (apex) is located at the level of the true vocal cords. The postcricoid area or pharygoesophageal junction is the anterior wall of the...
The anatomy landmarks are the mainstay to read a head and neck study,
so its deepest knowledge is needed to make the correct diagnosis.
the correlation between the ct/mri images and those seen by the otorhinolaryngologist are helpful to perform this task.
