Abstract:
The present study was both methodological and investigative in nature. This included the development of computerised rhinomanometry and establishment of cephalometric measurement apparatus together with a standardised lateral cephalometric radiography technique to record natural head posture. The method errors of both the measurement systems and the operator were tested by duplicate determinations and subsequent statistical analysis. Recordings for all the variables in the study were reproducible without systematic error and with a very small method error. Apparatus was used to record nasal respiratory resistance (NRR), craniofacial form and head posture in a control group for comparison with subjects with cleft lip (CL), cleft palate (CP), and unilateral cleft lip and palate (UCLP). The results of the rhinomanometric recording indicated that the bilateral nasal resistance did not differ significantly between the cleft samples and the controls. Unilateral measurements of nasal resistance showed higher values for the cleft side than for the non-cleft side, both in cleft lip (CL) and the unilateral cleft lip and palate (UCLP) samples. In the cleft palate (CP) sample as well as in the controls, unilateral nasal resistance did not differ between the two sides. Comparisons were made between cephalometric measurements for craniofacial form and head posture for each category of the clefting deformity and the controls and the statistically significant differences tabulated. Previous studies have demonstrated associations between cranio-cervical angulation and craniofacial morphology, and between airway adequacy and cranio-cervical angulation. In the present study, differences and correlations were calculated between face height, head posture and airway resistance which were in agreement with the predicted pattern of associations between cranio-cervical angulation and craniofacial morphology (face height) and between airway adequacy and cranio-cervical angulation.
