[A-mode ultrasonography and roentgenography in diagnosing chronic nonpolypoid maxillary rhinosinusitis]

The aim is to demonstrate diagnostic alternatives for A-mode ultrasonography in examining chronic nonpolypoid rhinosinusitis, its implementation, as well as its advantages and disadvantages in regards to roentgenography.

The prospective research conducted included patients with chronic nonpolypoid rhinosinusitis, at 79 maxillary sinuses. Chronic diseases are classified into two separate categories depending on the clinical entity. Comparative analysis of the ultrasound and roentgenography findings was conducted for both, while the status of the maxillary sinuses obtained by sunusoscopy provided the gold standard.

Generally speaking, the reliability of the A-mode ultrasonography in diagnosing chronic nonpolypoid diseases in maxillary sinuses was of a somewhat greater degree in comparison to roentgenography, amounting to 72.15% in relation to 60.76%. There is no statistically significant divergence in relation to the foregoing methods. A-mode ultrasonography is more helpful in the process of identifying liquid contents, and can be less utilized in identifying hypertrophic mucous membrane.

Ultrasonography is efficient, economical and quite simple for the implementation. Its chief advantage is to be perceived in the fact that both the patient and the examiner avoid being exposed to ionized radiation. Ultrasonography and roentgenography suggest lesser degree of utility and represent a triage method in detecting chronic nonpolypoid pathological conditions.
