Abstract:
Objective:To explore the clinical value of 16-slice spiral CT in diagnosing bony lacrimal passage fracture.Methods:16-slice spiral CT images of 65 patients,which were clinically proved as bony lacrimal passage fractures,were analyzed retro-spectively.Postprocessing of images was performed by GE AW 4.1.Multi planar reconstruction(MPR).The thin-thick axial images were compared with the MPR.Results:16-slice spiral CT showed clearly the fractures of lacrimal sac fossa and nasolac-rimal duct.All the 65 cases were compound fracture,most of which were naso-orbital-ethmoid fracture,including 45 cases of fractures of the frontal process of the maxilla,30 cases of the lacrimal bone fractures,40 cases of ethmoid bone fractures on the medial orbital wall,32 cases of nasal bone fractures,13 cases of the nasal process fractures of frontal bone,23 cases with naso-maxillary suture separations,17 cases with naso-frontal suture separations,20 cases with frontal-maxillary suture separations, 50 cases with lacrimo-maxillary suture separations,26 cases with internasal suture separations.There was no significant difference between the thin-thick axial images and the MPR in diagnosing bony lacrimal passage fracture.Conclusions:16-slice spiral CT can accurately display the location,extent and secondary changes of bony lacrimal passage fracture in detail.
