[Effectiveness coefficient for laryngographic closure of the glottis as a way of evaluating airway protection against aspiration of gastric contents].

Laryngographic examination was conducted on 35 men aged 45 to 65 with good hearing and proper pronunciation. Based on the examination, the proposed by the authors of this paper laryngographic closure effectiveness coefficient of the glottis (LCEC) was calculated as a way for evaluating protection of airways against the aspiration of food. Glottis occlusion serves an essential function as a mechanism protecting airways, especially in patients who have undergone horizontal supraglottic laryngectomy. The examination was conducted with the purpose of obtaining numerical values of LCEC, which will be treated as results of the controlled group during the examination of swallowing disorders in patients with partial laryngectomy.
