Abstract: Two cases with piriform fossa cancer underwent larynx lateral wall repair surgery.Case 1:The patient was admitted to the hospital because of "pharyngeal discomfort with swallowing pain for 2 months".Electronic laryngoscopy revealed neoplasm in the left piriform fossa.Space-occupying lesion in left piriform fossa and paranasal space was found in MRI scan.The pathological diagnosis of this patient was squamous cell squamous cell carcinoma (T2N1M0).Case 2:The patient was admitted to the hospital because of "blood in the sputum for more than 1 year".The electronic laryngoscope suggested neoplasm in the pharyngeal space and left vocal cord paralysis.Soft tissue thickening of the oropharynx and hypopharyngeal right wall was found in MRI scan.The pathological diagnosis of this patient was squamous cell carcinoma (T1N2M0).
