Figure 1: Plain radiograph of the postnasal space that shows how adenoidal – nasopharyngeal ratio was determined. B: Line drawn along straight part of anterior margin of basiocciput; S: Sphenobasioccipital synchondrosis; PS: Nasopharyngeal depth (line from anterior inferior edge of S to posterior superior margin of hard palate); AB: Adenoid depth (perpendicular line from B to point of maximal convexity of Adenoid); ANR: Adenoidal nasopharyngeal ratio; AB/AP: Adenoid depth/Nasopharyngeal depth
