Study on the development of the sinus maxillaris in children by tomography Chapter III: Correlation between the development of the maxillary sinus of children and the shape of their face

The relation between the development of the paranasal sinus of school children and the shape of their face was studied. (1) The maxillary sinus area, ethmoidal sinus area and frontal sinus area have a high correlation with the up-down, left-right and anterior-posterior diameters, respectively. (2) The maxillary sinus area, and ethmoidal sinus area have a close correlation with the maximum head length, zygomatic arch width, external eye-orbit diameter, mandibular angle width, nasal height, morphological upper face height and morphological face height. However, the frontal sinus area has no correlation with them. (3) It is not clarified by my experiment, whether the mandible of pupils has any relation to the development of their paransal sinus.
