Abstract:
OBJECTIVES: To evaluate the anatomic variations of the paranasal sinuses on computed tomographs. MATERIALS AND METHODS: The author examined the CT images of the paranasal sinuses retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. RESULTS: The highest incidence of anatomic variation of the paranasal sinuses in bilateral structures was agger nasi cell(73.2%), followed by concha bullosa(31.1%), Onodi cell(24.0%), Haller cell(19.8%), maxillary sinus septum(13.0%), paradoxical middle turbinate(2.5%), pneumatized uncinate process(2.0%), and bent uncinate process. The highest incidence of anatomic variation in midline structures was nasal septum deviation(53.2%), followed by nasal septumaerated(29.4%), bulla galli(24.7%) asymmetric intersphenoid septum(22.3%), and nasal septum spur(13.8%). The correlation between anatomic variation and paranasal sinusitis was not found. CONCLUSIONS: The results of this study will aid in the diagnosis and treatment of paranasal sinus diseases, especially in the treatment planning before functional endoscopic surgery.
