From 1977 to 1988, the authors treated a total of 295 cases of pharyngeal squamous cell carcinoma (excluding the nasopharynx), of which 78 cases originated in the posterior pharyngeal wall, counted male 48, female 30, aged 41 to 76 years old. Average 60 years old. 68 cases had not received treatment before (including 4 cases of laryngectomy due to laryngeal neoplasms), and 10 cases of residual or recurrent tumors after radiotherapy. The common symptoms of posterior pharyngeal squamous cell carcinoma were dysphagia and swallowing pain (58 cases), followed by neck mass (14 cases) or hoarseness (7 cases). The other 7 cases were found by accident when examining or treating other parts of the tumor. The tumor was completely confined to 20 cases in the posterior pharyngeal wall and 31 cases invading the pharyngeal wall, extending to the pear-shaped fossa, larynx, posterior ring area, or cervical esophagus in 27 cases. Of the 68 patients who had not received treatment, 65 were properly documented and could be staged according to AJC criteria: 6 in stage I, 24 in stage II, 19 in stage III, and 16 in stage IV. In 78 cases, surgical treatment was the mainstay
