ABSTRACT: 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.
