Objective:To investigate the value of the three-dimensional CT reconstruction by computer photo process system for laryngeal carcinoma and control study with pathologic feature. Methods: Fifty patients with laryngeal carcinoma were scanned by helical CT which photos were three-dimensionally reconstructed with a photo processing system,and the images were compared with pathologic feature.Results:Clear three-dimensional photo of the laryngeal was obtained through the reconstruction of the helical CT.The images could be circular fully around the axis of X,Y and Z in order to find the best view of the diagnosis.Ninety-six percentage of the TNM stage of patients according to the images of three-dimensional reconstruction were consistent with the TNM stage after operation.The safe edge was obtained in 98% of the surgery for patients.Good correlations were showed in the images of the three-dimensional reconstruction of the larynx and pathologic specimens.Conclusion:Good consistent of the three-dimensional images of the larynx with pathologic specimen were useful for diagnosis,operation design and education.
