Application of cone-beam computed tomography in the diagnostics of maxillary sinusitis of odontogenic origin – two case reports

The aim of the article is to highlight the potential for
early diagnosis of maxillary sinusitis of an odontogenic
origin with cone-beam computed tomography (CBCT).
Two cases of long-term patients treated for maxillary
sinusitis of an odontogenic origin are addressed.
Dental examination combined with CBCT facilitated
correct diagnosis, thus aiding optimal causal
treatment. Dental treatment proved a sufficiently
effective remedy in one case, whereas the other one
required surgical intervention. In the case of suspected
maxillary sinusitis of an odontogenic origin, close
cooperation of the dentist with an otolaryngologist
is recommended at an early stage of treatment. The
CBCT facilitates identification of the odontogenic
cause of the infection. This imaging technique allows
for a simultaneous and accurate assessment of the
maxillary sinuses, the teeth, and periapical tissues,
whilst eliminating the need for computed tomography
of the sinuses and the orthopantomograms.
