[Application of coronal CT scan and three-dimensional reconstruction in rhinology].
To display the structure of the Ostiomeatal Complex (OMC) more clearly, and provide clearer and more living imaging for safe functional endoscopic sinus operation and thoroughly eliminating the focus of disease, coronal CT scanning and 3-dimensional reconstruction were performed in 168 sinusitis patients (290 sides) and 107 patients with sinusitis and nasal polyposis (175 sides). The CT findings were compared with endoscopic examination and normal people were taken as control. The found of coronal CT and endoscopic examination are consistent in recognizing mucosal thickening within nasal cavity and sinuses. Three-dimensional CT is more living than common coronal CT in displaying the uncinate process and turbinates. Our conclusion is that coronal CT scan processes high values for recognizing nasal sinus disease, anatomical variants, disease extent and adjacent structures of OMC. Three-dimensional reconstructed CT make the image of OMC more stereoscopic, audio-visual and living.
