Theoretical basis: The presence of laryngeal carcinoma requires precise assessment of the feasibility of endotracheal intubation. Preliminary examination of the laryngeal structures is helpful in the selection of proper technique for ventilation.
The Aim of the study is to determine the degree of laryngeal obstruction in patients with laryngeal carcinoma. Materials and Methods: A prospective cohort study for determining the degree of laryngeal obstruction including 120 patients with laryngeal carcinoma operated in the Department of Otorhinolaryngology at the University Hospital “Queen Giovanna”– ISUL, Sofia, 2012-2015.
Results: Preoperative examination of the larynx is performed in all patients by Storz 8402 ZX fiber optic laryngoscope with video capability. The degree of laryngeal obstruction is determined by the Cotton-Myer scale. In 60 patients the degree of obstruction is up to 50% (1st degree), in 26 patients it is 51-70% (2nd degree), and in 34 patients the obstruction is 71-99% (3rd degree).
Conclusion: Preoperative determination of the degree of laryngeal obstruction is essential for choosing the proper technique for ventilation during tracheostomy in patients with laryngeal carcinoma.
