X-ray results. (A) Adenoid index. A: thickness of adenoid; N: nasopharynx cavity width. (B) Lateral cranial markings. N: the most concave point of the bone between the anterior nasal spine and the edge of the upper alveolar; S: the most concave point of the bone between the anterior nasal spine and the edge of the upper alveolar; A: the most concave point of the bone between the anterior nasal spine and the edge of the upper alveolar; B: the most concave point of the bone between the anterior nasal spine and the edge of the upper alveolar; Me: the lowest point of the chin; Gn: the midpoint between the pre-chin point and the sub-chin point; L1: the midpoint between the pre-mental point and the submental point; U1: the midpoint between the pre-mental point and the submental point; Pog: the midpoint between the pre-chin point and the sub-chin point; ANS: the tip of the anterior nasal spine is used as one of the two landmark points to determine the palatal plane.
