OBJECTIVE: To approach the clinical significance of pyriform sinus carcinoma invading to pyriform sinus apex.
METHOD: Forty-three cases of surgical specimens from total laryngectomy and partial hypopharyngectomy of pyriform sinus carcinoma were made with the organ subserial sectioning and pathological study.
RESULT: Pyriform sinus apex is the inferior 1/3 region of pyriform sinus. If pyriform sinus carcinoma invades its apex, the cancerous tissue easely infiltrated the adjacent structure and organs.
CONCLUSION: The invasion of pyriform sinus apex is the beginning position and the most important sign of invading downward the tissue and surrounding organs in the inferior position of hypopharynx. When surgery treatment is performed, the total laryngectomy and hypopharyngectomy of ill hypopharynx is appropriate and necessary.
