Dilatation of the nasal valve by expansion of the vestibular oris (EVO)

摘要

Introduction: The main signs and symptoms of ankyloglossia with deviation of the epiglottis and larynx (ADEL) are sleep disorders caused by respiratory restraint. The author contrived the surgical procedure of correction of the glosso-larynx (CGL) and expansion of the vestibular oris (EVO) for the cure of ADEL. CGL increases vital capacity (VC) and forced expiratory volume in 1 second (1% FEV). EVO reduces nasal airflow resistance. The most important component of nasal airflow resistance is the nasal valve. Purpose: Our purpose was to measure how wide the nares were dilated after EVO. Method: The width of the nares, height of the nose, length of the philtrum and width of the lip were measured in patients who had signs and symptoms of ADEL, before and after EVO. Result: Significant increases were observed in the width of the nares, height of the nose and length of the lip after EVO. Conclusion: This study confirmed that the nares dilate after EVO. Not only the amelioration of nasal respiration by EVO increases immunity, but also aesthetic effects are obtained after EVO.
