Συμβολή της κάθετης ημιφαρυγγολαρυγγεκτομής στην αντιμετώπιση των νεοπλασμάτων του απιοειδούς βόθρου

Abstract

Supracricoid vertical hemipharyngolaryngectomy is a conservative surgical procedure which provides excellent local control of the disease without harming the laryngeal function. It is indicated in cases of malignant invasive tumors of the pyriform sinus (invasive squamous cell carcinomas) staged T1 to T3. The basic contraindications include old aged patients, significant pulmonary disease that leads to respiratory failure, invasion of the preepiglottic and/or paraglottic space, invasion of the apex of the pyriform sinus or the thyroid cartilage, invasion of the retrocricoid region or the posterior pharyngeal wall beyond the midline and invasion of the base of the tongue. The results of the long term follow up in our series, as well as in other surgical series of foreign institutions show that supracricoid hemipharyngolaryngectomy appears to be more effective regarding the local control of the disease, compared with radiotherapy or other conservative surgical procedures. Besides, the preservation of the larynx provides the patients with a better quality of life.
