[Pathophysiologic mechanisms of functional disorders of the cardiorespiratory system in snoring].

Disturbances in the function of cardio-respiratory system due to nasal obstruction, accompanied by snoring, are described. Obstructions to other levels, oropharynx, pharynx and larynx, also inducing such disturbances are mentioned, with particular reference to snoring which may lead to the development of apnea during sleep. The need of a multidisciplinary approach to such patients is underlined, with a very specific role of the otorhinolaryngologist, especially when obstruction of the nose has caused such a disturbance. The act of snoring can be eliminated or diminished, and the development of obstructive apnea during sleep prevented or interrupted by accurate indications for and properly performed reconstructive surgery of the nose.
