Abstract
Ankyloglossia with Deviation of the Epiglottis and Larynx (ADEL) is a condition in which the tongue, epiglottis and larynx are displaced upward and forward. This condition occurs independent of the existence or absence of the frenum linguae. This condition not only increases the resistance of the upper airflow, it also inhibits respiration. The Correction of the glosso-larynx (CGL) procedure cuts several bundles of genioglossas muscle from the underside of the tongue. As a result of the procedure, the tongue, epiglottis and larynx move backward and downward. In addition, the epiglottis and larynx stand up straight with the epipharynx, or post-nasal cavity, lined up in the sagittal image.
Changes of sleep qualities were measured on 20 adults that had chief complaints with sleep disorders. They had CGL operation for their ADEL. Their sleep qualities were compared before CGL with one month after CGL.The Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI) and wrist-band style actinography that built in high-sensitive accelerometer were employed for evaluation of their sleep qualities.Improvements of sleep in daytime and sleep quality were affirmed. Significant improvements were observed in the length of sleeping time during daytime, sleep efficiency, arousal time after sleep and the longest sleeping time by measurements of actigraphy. Ameliorations of respiration during sleep were resulted in increase of sleep efficiency, decrease of daytime sleepiness. It was shown that the CGL was useful treatment for the improvement of sleep disorders among ADEL patients.
