ABSTRACT

To observe the association between local properties of larynx cancer and neck metastasis.

In total, 119 patients who underwent total or partial laryngectomy and neck dissection for laryngeal carcinoma at the Otolaryngology Head and Neck Surgery Clinic of Health Sciences University Gaziosmanpaşa Taksim Training and Research Hospital between 2003 and 2016 were enrolled in this study. Postoperative pathological examinations included tumor histopathology, tumor differentiation; perineural, cartilage, and lymphovascular invasion; laryngeal primary tumor localization; anterior commissure; piriform sinus apex; tongue root; pre-epiglottic region; thyroid cartilage; band; aryepiglottic plateau; laryngeal ventricle; arytenoid vocal processes; arytenoid involvement; vocal cord movements; and metastatic lymph node status in neck dissection.Tumor histopathology and the association between invasion and neck dissection in the anatomical regions that determine local spread were investigated.

Patient age, opening of preoperative tracheotomy, and status of vocal cord movements did not affect neck metastasis. Piriform sinus, tongue base retention, band involvement, aryepiglottic plica involvement, involvement of laryngeal face epiglottis, and involvement of arytenoid significantly affected local spread.

Although similar findings have been reported in the literature, multidisciplinary studies involving more patients, especially those with neck metastasis, are warranted to arrive at a definite conclusion.
