There are many forms of physical energy which, during such a short period of time, had rich history and which found wide application in the science of medicine, as was the case with the ultrasound in the last fifty years or so. The ultrasound got its affirmation rather soon, as valuable biologically harmless method used for detecting and explaining various pathological conditions in the science of medicine, and therefore in otorhinolaryngology as well. In the following study, the technique of the ultrasound examination of paranasal sinuses is described in details, standard echogramic patterns are
represented, and means of their interpretation are explained as well, regarding the fact that it is not standard. Special focus is
on the literature review whereby the valorization of the ultrasonography in relation to acute and chronic diseases of the maxillary sinuses is performed. In that sense, over 30 extracts by the authors from all parts of the world are represented. The
insight into the results of the latter reports, as well as the author own experiences, lead to the conclusion that the A-mode
ultrasonography represents an impartial method applicable in diagnostics of the maxillary sinus diseases. It is practical and
economical for it is performed quickly and in a rather simple manner. It is an invasive and painless method, comfortable for
the patient. Main advantage in relation to other radiological methods lies in the avoidance of the patient and medical doctor's
exposure to X-rays, therefore the ultrasonography method is a matter of choice for diagnosis of primarily maxillary sinus
acute diseases with children and pregnant women. Due to extraordinary sensitivity in the evaluation of the sinus secret, with
acute diseases it represents valuable, impartial supplementary method. On the other hand, due to weaker peculiarity, with
chronic diseases ultrasonography only represents a selective method
