Squamous Cell Carcinoma of the External Auditory Canal and Middle Ear: An Operation Combined with Preoperative Chemoradiotherapy and a Free Surgical Margin

Abstract

The tumor-free surgical margin was important to survival. When T4 lesions did not involve the pyramidal apex, carotid canal, dura, or any lymph nodes, the surgical intervention improved the estimated survival rate to a level as good as T3 lesions.
