To determine if there are changes in craniofacial form during childhood growth that are different between children with no history of otitis media (control) and children with otitis media with effusion (OME). Eight children, 4 control and 4 OME, had standard lateral and AP cephalometric x-rays using accepted clinical procedures at 3.5 and 5.5 years of age. Ten anatomical landmarks were identified and used to construct angular and linear measures for 6 anatomical regions of the craniofacial complex. The change in angular and linear measures from 3.5 years of age to 5.5 years of age in an individual was calculated. The net change was used to compare craniofacial growth between control and OME groups. The means for the two groups were compared using a Student’s t test for significance at P≤0.05. Five constructed measures were significantly different between the groups. The measures of change in nasopharyngeal (NP) width, NP height, the magnitude of the tensor veli palatine muscle- membrano-cartilaginous ET (mcET) vector, the height of the NP Eustachian tube orifice relative to the hard palate and the directional component of the mcET inferio-medial vector relative to the cranial base were less in the OME group. In conclusion, the results reveal that the measures of changes in craniofacial morphology from 3.5 to 5.5 years of age are different between control and OME groups. These differences may be reflected in the anatomy and function of the Eustachian tube system.
