Question

what is the role of Hypopharynx .pts. Aryan​ and shreey​

Answer 1

Answer:

The hypopharynx is lined by stratified squamous epithelium, and most tumors of the hypopharynx are SCCs (Fig. 2-61). The risk factors for SCC of the hypopharynx include alcohol abuse, smoking, and previous radiation therapy. Patients with Plummer-Vinson syndrome have a higher incidence of postcricoid carcinoma. Extensive submucosal growth is common and can be appreciated only on imaging. The airway may be effaced and displaced. Most patients have metastases to the cervical nodes at presentation. Between 4% and 15% of patients with SCC of the hypopharynx have a synchronous or metachronous second primary tumor.

Answer 2

The hypopharynx functions to guide food into the esophagus and away from the larynx, during normal swallowing. The hypopharynx extends from the level of the hyoid bone to the inferior edge of the cricoid cartilage, corresponding to the C4 through C6 vertebral bodies.
