Study Arms (3)

laryngeal carcinoma

EXPERIMENTAL

patients with T1-T2 (some T3) laryngeal carcinoma will undergo treatment using thulium contact laser surgery - tumour resection

Procedure: laryngeal carcinoma

Procedure: bilateral vocal cord paralysis

subglottic stenosis

EXPERIMENTAL

patients with subglottic stenosis treated endoscopically (incisions and dilatation) will be treated with thulium laser surgery

Procedure: subglottic stenosis
