Computed tomography (CT) scan used to evaluate the pharyngeal airway
volume by the using semi-automatic segmentations to calculate real volumes instead
of estimates based on linear measurements .
The purpose of this study was to Measure the pharyngeal airway volume and
the size of the face , then compare between pharyngeal airway volume in mouth
breathing subjects and nasal breathing subjects , find the gender difference between
two groups , find a correlation between pharyngeal airway volume and the size of the
face and finally comparison between different skeletal classes.
Computed tomography (CT) scan were records of 50 Iraqi mouth breather
subjects (28 male , 22 female) , with the age range (18-35) years in which they
complain from nasal obstruction , the patients were examined by the otolaryngologist
by using head mirror, speculum and flexible Nasofibroscopy to certify their
complaint and to identify the cause of the obstruction.
The control group was comprised of 20 Iraqi subjects (10 males ,10 females)
the age range was (18-35) years, also they were examined by the otolaryngologist to
certify the absence of nasal obstruction. Also all the control subjects were nasal
breathing with normal occlusion.
The mouth breather sample were divided according to the gender in to male
and female group .Also divided according to anteroposterior relationship in to CL
I,II and III depend on synthetic lateral cephalogram and Foster method .
Abstract
IV .
In this study it has been shown that a statistically significant relationship
between the pharyngeal airway volume and the mode of respiration ,Also there was a
statistically significant relationship between pharyngeal airway volume and gender.
The pharyngeal airway volume was larger in nasal breather group rather than
in mouth breather group and it was larger in male rather than in female.
The size of the face was larger in male rather than in female and most of mouth
breather subjects was skeletal CL II.
