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.展开更多

This study included 603 patients whose adenoids were curetted during the 11-year period. 90% of patients were 2 to 9 years old. The rate of curetted adenoid vegetation among the tonsillec-tomized cases was 80% among patients from 1 to 6 years old and 70% among patients of 7 and 8 years old. The rate remarkably decreased from 9 years of age. The average weight of the curetted adenoids in each age group ranged from 0.7 g to 1.9 g. There was no statistical correlation in the distribution of the average weight of the curetted adenoids between males and females as well as between the weight of the tonsils and the weight of the curetted adenoids. A hypothesis on the cause of adenoid hypertrophy was presented in this study.展开更多
