[Internal and external chordectomy via laryngofissure with the use of CO2 laser].

Introduction: The aim of this work was to evaluate the therapy results of patients with glottic carcinoma in the T1NoMo advanced clinical stage on internal or external chordectomy via the thyroid cartilage with the use of CO2 laser.

Material And Methods: The study was conducted in 110 patients, including 7 women aged 52-68 and 103 men aged 52-73, who were treated in the Department of Otolaryngology and Laryngological Oncology, Military Medical Academy Teaching Hospital in Lodz, during the years 2010-2012, due to laryngeal carcinoma (T1N0M0).

Results: The studied material was subjected to external chordectomy via laryngofissure in 51 men (46.4%), and internal chordectomy with the use of CO2 laser in 52 men (47.2%) and 7 women (6.4%). In the patients operated via laryngofissure, the following types of external chordectomy were performed: IV - in 25 cases (49.0%), Vc - in 12 cases (23.6%), and Vb and Vd - in 7 cases each (13.7% each). Internal chordectomy was conducted with the use of the following types: III - in 31 cases (52.5%), IV - in 15 cases (25.4%) and Vd - in 13 cases (22.1%). During the post-operative follow-up of 1-3 years, no recurrence of carcinoma was observed.

Conclusions: The place and size of carcinoma are often dependent on the type of internal and external chordectomy, which is preceded by tracheotomy and is usually dependent on a patient's consent. Too short post-operative follow-up does not allow for the comparison of effective therapies of the two surgical methods.
