This comparative study was designed to ascertain whether any differences existed
between skeletal class ¥± malocclusion ((A total of 121 males and 125 females representing different ages were examined. For
the purpose of comparison, each malocclusion was classified by sex, and further
subdivided into three different age groups; 12-years-of-age-and-under,
13-to-15-years-of-age, 16-years-of-age-and-over.
The conclusions were as follows ;
1. There were no differences in the area of bony nasopharynx between both types of
malocclusion.
2. As a whole, the areas of adenoids of skeletal class ¥± malocclusion tended to be
larger than those of skeletal class ¥² malocclusion. However, statistically significant
differences were found only in the 12-years-of-age-and-under groups of both sex.
3. The areas of nasopharyngeal cavity of skeletal class ¥² malocclusion were in
general larger than those of skeletal class ¥± malocclusion. Statistically significant
differences, however, were discovered in the 12-years-of-age-and-under group as well
as the 13-to-15-years-of-age group of male.
4. There were significant differences with respect to the rate of area of adenoids to
nasopharynx in the 12-years-of-age-and-under groups of both sex and
13-to-15-years-of-age group of male.
5. Cranial base angle showed positive correlation with the depth of nasopharynx and
negative correlation with the height of bony nasopharynx.
6. adenoids and pharyngeal cavity.
