Analysis of 95 cases of squamous cell carcinoma of the external and middle ear

Local infiltration seems to be the main behavior of SCC in the external and middle ear. Early diagnosis and treatment were important because SCC in the earlier stage is susceptible to be cured. For tumors of advanced stage, operation should be performed with pathologically tumor free margin, and operation combined with radiotherapy and chemotherapy could improve the survival. Tumor stage adds more influence on survival than its location. Recurrence and metastasis mainly occur in advanced stages and result in a poor survival.
