Maxillary sinusitis of odontogenic origin: cone-beam volumetric computerized tomography-aided diagnosis.

OBJECTIVE

Study of radiographic features of maxillary sinusitis of odontogenic origin as visualized on 3-dimensional advanced imaging is essential for prompt diagnosis and appropriate management. This study attempted to describe and delineate radiographic characteristics of this condition.

STUDY

DESIGN

Three cases of failed endodontic therapy presenting with confounding clinical signs and symptoms were subjected to 3-dimensional imaging with cone-beam volumetric computerized tomography (CBVCT) to evaluate changes in the maxillary sinuses.

RESULTS

CBVCT showed varying involvement of the ipsilateral maxillary sinus in all 3 cases. The presentation varied from presence of intrasinus fluid to reactionary osseous response within the sinus.

CONCLUSIONS

CBVCT as a diagnostic aid to evaluate the involvement of the maxillary sinuses in cases of endodontic treatment failure seems to assist with formulation of a definitive diagnosis. Appropriate interventions may be instituted, including an otolaryngology consultation.
