Pain during the healing phase is the result of exposure of the superior constrictor muscle and associated nerve endings to mechanical stretch, the ingestion of hypotonic solutions, and abrasion by food.
Also, leaving a coating layer of semiviable tonsillar tissue may reduce exposure of the veins in the tonsillar plexus and superior constrictor muscle. These principles have guided the development of the intracapsular tonsillectomy technique.
In its cervical portion, the nerve runs cranially behind the left lobe of the thyroid gland, under the inferior pharyngeal constrictor muscle, and penetrates into the larynx behind the cricothyroid joint between the thyroid ala and the cricoid lamina.
Ventral superficial branchial constrictor muscles (VRSUPC): five pairs, membranes among them are both the origin and the insertion surface of each muscle, running anteriorly from its origin.
A ZD is a herniation of the pharyngeal mucosa through an area of natural weakness between the fibers of the inferior constrictor muscles. (1) Attempts have been made to classify the size of the pouch as demonstrated by contrast radiology.
The superior areas lie at the junction of the superior and middle pharyngeal constrictor muscles. Intraluminally, this area is located in the area of the inferior pole of the tonsil next to the vallecula.
One of these areas is at the junction between the superior and middle pharyngeal constrictor muscles. When the ostium of a pharyngocele is located in this area, it is usually situated on the internal surface of the pharynx, in the region inferior to the lower pole of the tonsil and at the lateral side of the vallecula.
Dysphagia is thought to be caused by toxin diffusion into the constrictor muscles. Toxin diffusion has been shown to be dose-related.
