Vocal Cord Fixation In Laryngeal Carcinoma

Supracricoid laryngectomies: Long-term oncological and functional results

“…The vertical hemi-laryngectomy was designed to address the problem of glottic carcinoma that has either spread beyond the borders of the glottis or which resulted in limitation or fixation of true vocal cord mobility [13]. As a matter of fact, all vertical partial laryngectomy procedures permit only partial resection of the paraglottic space and of the thyroid cartilage, both of which may potentially be invaded by carcinoma; in 1973, Olofsson et al demonstrated how squamous cell carcinoma can spread through the collagen fibres and penetrate the muscular aponeurosis [14]. These microscopic neoplastic outlets can escape surgical removal and may account for the significant recurrence rate.…”

Supracricoid partial laryngectomies: Oncologic and functional results

“…In fact, on analysis of 23 larynx with serious true vocal cord fixation, Kirchner and Som 8 found that the neoplastic invasion was limited to the paraglottic area and had not invaded the cricoid or thyroid cartilage. On the other hand, Olofsson et al 9 and Hirano et al 10 observed an invasion of the thyroarytenoid muscle in their anatomopathologic studies on all cases of true vocal cord fixation. In these particular clinicopathologic cases, other authors used vertical surgery, resulting in relapse in from 9% to 46% of the patients.…”

Treatment of T3carcinoma of the larynx by surgery or radiotherapy

“…22 The present series suggests that radiotherapy is an oncologically sound treatment for T, laryngeal tumours even though 71 % of patients undergoing total laryngectomy either as primary surgical procedure or as treatment for failed radiotherapy had cartilage invasion. Of the surgical options, total laryngectomy is generally accepted as the procedure necessary to give a reasonable chance of cure.…”
