Introduction: Sight of vocal cord paralysis express a special upper airway obstruction, exposed conditions signs and symptoms of obstructive sleep apnea.

The aim of the presentation was to analyse a particular glottical stenosis circadian behavioural procession implementing with sleep medical instruments.

Methods: Ten patients (9 women, 1 man) were enrolled, treated with vocal cord paralysis past surgical failures of thyreoidectomy. Mean age was 55,8 (SD:6,74).

After fiberoscopical physical assumpted examination all participants underwent functional breath ability test and a voice record. Qualitiy of Life, Epwort Sleepiness Scale, Berlin and Sleep Habits Questionnaires were filled. The loudness of snoring was estimated on a visual analog scale. Before endolaryngeal arytenoid lateropexy (EAL) drug induced sleep endoscopy, polygraphy was permormed. Pre- and postoperative data assumed. Statistical analysis was performed using paired t-test. Correlation between preoperativ Apnoe-Hypapnoe Index (AHI) and Peak Inspiratory Flow (PIF) values changes were measured with Pearson’s coefficent.

Results: AHI represent significant deflection after EAL and the primary investigated parameters improved. After the surgical intervention most of the nighttime-measured values indicated regression beneath improved PIF and daytime datas.

Conclusion: Results attract the attention that mild daytime dyspnoe may connected with dangerouos nightime signs, caused fatal outcomes correlated with obstictive sleep anea. The patient’s quality of life was improved proceed to EAL. Advisedly in the recovery period (up to 6-12 months) of the paralysis suggested to do laterofixation instead of wait and see policy.
