ABSTRACTIntroduction: In glottic cancer, cord fixation and cord-arytenoid fixation are staged as T3, but patients with cord-aritenoyd immobility have poor outcome compared with the first due to increased neoclassic infiltration in the laryngeal structure; the fixing of both glotic structures means massive infiltration of the para-glotic space. The purpose of this paper is to know if there are some difference between patients with cordal fixation and cord and arytenoid fixation. Material y methods: Retrospective analysis of a series of patients with SCCL. Variables analyzed: T-staging, tumor site, and arytenoid-mobility/fixation. These were correlated with histopathological node status. Statistical significance was evaluated with χ2 test. Results: Ninety-one patients included, 82 males and 9 females; median age of 66 years. The most frequently affected site: glottic-subglottic region (38) followed by glottis (22). The most frequent T stage was T3 (46%) followed by T4 (25%); 81% were N0 and 19% N+. 76 (83%) had arytenoid fixation. Factors associated with CNM were glottic-supraglottic infiltration (65%) and arytenoid fixation (17 vs 0%, p = 0.048). None of the patients with arytenoid mobility had CNM. Tumor infiltration to thyroid gland was demonstrated in 14%. The most important risk factor was subglottic extension (17%; p = 0.5). Conclusions: Arytenoid-cord fixing is associated with increased chance of lymph node metastases and probably worse prognosis compared with patients with only cord immobility.
