Abstract: | Background We have previously proposed the use of Doppler ultrasound to non-invasively stage sinus infection, as we showed that acoustic
streaming could be generated in nonpurulent sinus secretions and helped to distinguish it from mucopurulent sinus secretions.
In order to continue this development of a clinically applicable Doppler equipment, we need to determine different dimensions
of the paranasal sinuses, especially the thickness of the anterior wall of the maxillary sinus (at the canine fossa). To the
best of our knowledge, this is the first report on the thickness of the canine fossa. This study aimed to (a) estimate different
dimensions of the maxillary and frontal sinuses measured on computed tomography (CT) of the head, (b) define cut-off values
for the normal upper and lower limits of the different measured structures, (c) determine differences in age, side and gender,
(d) compare manually and automatically estimated maxillary sinuses volumes, and (e) present incidental findings in the paranasal
sinuses among the study patients. |
