Polysonographical evaluation in a case of moderate osas treated with mandibular advancement device.

Abstract

Background: The Obstructive Sleep Apnea Syndrome (OSAS) is a clinical picture characterized by partial or complete obstruction of the upper airway during sleep, associated with a reduction of oxygen saturation in the blood.The most common symptoms are: apnea sleep, snoring, headache, sleepiness, reduced concentration and memory, irritability, increased blood pressure and dry mouth.

Materials and methods: It was examinated a not-smoker man of 54 years that suffers of roncophaty. He did physical examination, rhinoscopyexam, faringoscopy, rhinofibrolaringoscopy, gnathological evaluation and polysomnographic examination performed with multichannel polygraphy (VitalNight). From the performed examinations, it has been diagnosed a moderate form of obstructive apnea sleep syndrome. He was treated with a mandibular advancement device and it was repeated the polysomnographic exam.

Results: Comparing the results of the polysonographic examination performed before and after the treatment, the patient's clinical picture clearly improved. It has shown a clear reduction of obstructive apneas, hypopneas and snoring.

Conclusions: The use of a mandibular advancement device is certainly a valuable aid in the treatment of moderate type OSAS. The quality of diurnal life is also improved as shown with Sleepness Epworth Scale.
