The incidence of thyroid cartilage invasion in early-stage laryngeal carcinoma: Our experience on sixty-two patients

Laryngeal cancer represents 4,5% of all malignancies and 28% of cancers of the upper aerodigestive tract. Pretreatment staging of laryngeal carcinoma should involve evaluation of thyroid cartilage invasion. Cartilage invasion which determines T stage in laryngeal cancer can be detected in 26-75% of the patients and if not detected preoperatively, may cause errors in staging in 40-50% of the patients.1 In recent TNM classification inner cortex involvement is classified as T3 and outer cortex invasion is T4a.2 This article is protected by copyright.
