Abstract

This study was made to investigate the effect of adenoidectomy on dentofacial skeleton in naso-respiratory dysfunction children. The clinical material compromised the 24 children in a previous study who had naso-respiratory dysfunction and 24 children who were the nasal breathing with normal occlusion. The cephalograms were taken at the initial examination and 1 year later for the control group and experimental group the paired sample statistical analysis was performed. The results were as follows. 1. In cranial base variable, difference between two groups were not statistically significant. 2. In craniofacial variables, experimental group showed brachyfacial pattern but control groups didn't show significant growth pattern. 3. In maxillary variables, experimental group showed flattening the plane. 4. In mandibular variables, experimental group showed the decrease of mandibular plane angle and gonial angle. 5. In facial height variables, experimental group showed horizontal growth rotation.
