includes the left and right piriform sinuses, which expand around the sides of the larynx and lie between the larynx and the thyroid cartilage; the lateral and posterior hypopharyngeal walls; and the postcricoid region extending from the level of the arytenoid cartilages to the inferior border of the cricoid cartilage.
Clinicopathological and immunohistochemical analysis of spindle cell carcinoma of the larynx or hypopharynx
: A report of three cases.
While there was a significant increase in the oropharynx and hypopharynx
values in all groups, the increase of nasopharynx values from T1 to T2 was only insignificant in the control group.
In many patients with carcinomas of the hypopharynx
, a degree of pulmonary and cardiovascular compromise is expected (10,11) (Fig.

. Ann Otol Maxillofac Rhinol Laryngol.
This relaxation is initiated by a transient inhibition of the cricopharyngeus, allowing the movement of the bolus from the hypopharynx
into the esophagus.
There is only one other similar report; a 16month-old girl who had a toothbrush extracted from her posterior hypopharynx
two months after a fall .
Based on tissue biopsies, the histopathological diagnosis for the lesion in the right piriform recess of the hypopharynx
was squamous cell carcinoma (Figure 3).
Benign tumours are rare in hypopharynx
and most of the malignant tumours are squamous cell carcinomas.
Oropharyngeal examination revealed a smooth-surfaced mass with a vertical movement between the oropharynx and hypopharynx
. Flexible fiberoptic laryngeal examination showed a smooth-surfaced polypoid mass that originated from the right posterior pharyngeal wall in the hypopharynx
The standard measurement for the nasopharynx is 17.5 [+ or -] 2.5 mm; 13 [+ or -] 2 mm for the oropharynx and 16.5 [+ or -] 3.5 for the hypopharynx
. Accordingly, the upper airway can be classified into: normal, slightly reduced, moderately reduced or severely reduced, depending on how many standard deviations below the standard value is.
