Figure 1

Illustration and CT images of major (left) and minor (right) thyroid or cricoid cartilage invasion (TCCI). The AJCC 7th edition staging manual for laryngeal tumors classifies minor TCCI (i.e. invasion limited to the inner cortex) as T3 and major invasion (i.e. invasion into both inner and outer cortices) as T4. Both minor and major TCCI are staged as T4 for hypopharyngeal tumors.
