Can sleep apnea affect vocal cords?

Conclusion. This case series of documented obstructive sleep apnea related to paradoxical vocal cord movement suggests that this entity occurs during sleep with airway obstruction. Further clarification of etiology of PVCM during OSA and its management is needed.

Can CPAP cause voice problems?

The usage of nasal CPAP seems to induce vocal changes that are perceived as mild to moderate hoarseness, together with an increase in the perturbation parameters. These seem to be secondary to the upper airway dryness reported in these patients.

Can sleep apnea cause throat?

If you suffer from a consistent sore throat or dry mouth, you may have sleep apnea and should seek medical treatment.

What is bilateral vocal cord paralysis?

Bilateral vocal fold paralysis means that both vocal folds will not move. People with this condition may need a tracheotomy if the vocal folds are close to a closed position which interferes with breathing. A tracheotomy is an opening made in the neck. They breathe through this opening.

What are long-term effects of CPAP use?

Among patients with long-term usage of continuous positive airway pressure (CPAP) therapy, several mask-related side effects (MSREs) were associated with CPAP nonadherence and residual excessive sleepiness (RES), according to study findings published last week in Respiratory Research.

What are the long-term effects of CPAP?

Obstructive sleep apnea (OSA) can result in hypertension and significantly increase cardiovascular morbidity and mortality. There are few reports on the long-term effects of continuous positive airway pressure (CPAP) on blood pressure in patients with uncontrolled hypertension with coronary heart disease (CHD) and OSA.

What affects the pitch coming from the vocal cords?

The excitation of the vocal folds is however very different from the excitation of a string in that is is caused by the passage of air through the opening between the folds. The muscles of the larynx change the elasticity and tension of the vocal folds to determine the pitch of the sound.
