Abstract

Background: Chronic respiratory obstruction can be produced by prolonged inflammation of the nasal mucosaassociated with allergies or chronic infection. It can also be produced by mechanical obstruction any where withinthe nasorespiratory system from the nares to the posterior nasal change. There may be a relation between theskeletal features of the facial skeleton and the respiratory pattern and this relation should be studied carefully. Thisstudy aimed to study and compare the relation between the nasal obstruction and the skeletal features of the facialskeleton in adults between the sample and control groups and to find the Pearson correlation coefficient betweenthe variables related to the nasomaxillary complex for the sample and control groups.Materials and methods: The sample is composed of 50 Iraqi Arab adult patients out of 167 with age range from 18-35years, having nasal obstruction had been examined in Tikrit general hospital and identified by the E.N.T. specialist.The control group will be 50 subjects out of 150 in the same age group and also had been examined and identifiedby the E.N.T specialist in Tikrit general hospital as having no nasal obstruction. Twelve linear measurements and a ratiowere determined on each radiograph. For each variable, the arithmetic mean, the standard deviation, and thestandard error were calculated. For statistical evaluation, an independent-samples t-test was performed. ThePearson correlation coefficient was calculated to indicate the relationship between nasal and maxillary variables.Results: There was no significant difference between the sample and control groups for the skeletal features of thefacial skeleton except the ramal height of the right and left sides and there was weak correlation between the nasaland maxillary variables for the sample and control groups.Conclusion: There is no effect of the nasal obstruction on the skeletal features of the facial skeleton in Iraqi adultsample.
