Severe habitual snoring is thought to bea pre-stage of obstructive sleep apnea syndrome (OSAS) . Recently, dental treatment for OSAS and snoring has become common in Japan. The aim of this experiment was to study the efficacy of a linked analysis of apnea and snoring as a simple diagnostic method. A 49 year-old male diagnosed with OSAS volunteered to participate as study subject. A dental splint was used as therapy, the nights before and after wearing the splint, linked recordings of an Apnomonitor II (which includes pulsoximetry) and of snoring sounds were carried out. Wearing of splint the brought about decrease in both the apneaindex (from 22.8 to 9.7 times/h), and in the disaturation time of hypoxia (from 38.8% to 14.6%) . After therapy with the splint we confirmed that snoring had disappeared. The linked analysis made it possible to study the relationship between apnea and snoring sounds. These results suggest that linked analysis with an Apnomonitor II and snoring sounds is useful for simple diagnosis of OSAS and snoring noise level.
