Cricopharyngeal dysfunction, with incipient Zenker’s (1 of 1)
This patient with cricopharyngeal dysfunction is just beginning to form a Zenker’s pouch. Note that the cricopharyngeus muscle (light grey “thumb” at asterisk) is beginning to turn upwards and become more slender. The volume of barium below the dotted line is inside the incipient Zenker’s pouch. Over months or years, this pouch would stretch and develop into a true Zenker’s pouch.
Zenker's diverticulum (1 of 3)
This view is a moment after a completed swallow of blue-stained applesauce.
Zenker's diverticulum (2 of 3)
Same view, a second later, as blue-stained applesauce emerges from the Zenker's diverticulum upward (toward the camera) into the postcricoid area.

Another second later, applesauce continues to re-emerge into the hypopharynx.
Reflux into hypopharynx (1 of 3)
The patient has swallowing problems typical of cricopharyngeal dysfunction. This swallow study reinforces that impression as well as the likely presence of a Zenker's diverticulum. In this photo, blue-stained water has just been swallowed, and the vocal cords are beginning to open. At this point, the hypopharynx contains no residue.
Reflux into hypopharynx (2 of 3)
One second later, the blue-stained water begins to emerge from just above the cricopharyngeus muscle into the "swallowing crescent".
Reflux into hypopharynx (3 of 3)
Another two seconds later, the larynx has fully opened post-swallow. The post-swallow hypopharyngeal re-emergence of the blue-stained water is apparent.
Orientation (1 of 4)
The 'X' is for orientation with next photo; 'A' is for right arytenoid eminence (left of photo). The arrow points to the area of focus of the next photo.
View into post-arytenoid and post-cricoid area (2 of 4)
View into post-arytenoid and post-cricoid area. The 'X' orients to the same place in photo 1. The esophageal entrance is just beginning to appear at the arrow.
Esophageal and Zenker sac openings (3 of 4)
Descending further, we see two potential openings. 'E' designates actual esophageal opening and 'Z' the opening to the Zenker's sac. Between the dotted lines is the cricopharyngeus muscle bar.
Cricopharyngeus muscle bar (4 of 4)
At very close range. Esophageal entrance is indicated at 'E' and the Zenker's sac opening at 'Z' with the cricopharyngeus muscle bar (CPM) separating the two.
Zenker’s diverticulum (1 of 4)
This middle-aged woman has had a known Zenker’s diverticulum for several years. She has now reached a point of frustration that has motivated her to proceed with cricopharyngeus myotomy. The series that follows explains some of the reason for her frustration. In this view, the patient has just completed a swallow of her saliva.
Saliva from Zenker's sac (2 of 4)
A few seconds later, saliva begins to return upwards into the post-arytenoid area (at arrow) from the Zenker’s sac.
Forced to re-swallow (4 of 4)
A few seconds later, sufficient saliva has welled up from the sac that the patient is forced to re-swallow, taking her back to the appearance of the first photo in this series, only to begin the same cycle depicted in these four photos again and again.
