Background: The complication of frontal recess brings many difficulties to the doctor’s surgery operations, and comprehensive understanding of frontal recess anatomy is essential for the successful treatment of subjects with frontal sinus disease. The purpose of the study is to describe the feature of the 3D model of frontal recess, and obtain the true image of the important anatomical structures of the frontal recess region to conduct surgery. Methods: A retrospective study of thirty Chinese subjects (60 sides) without frontal disease underwent spiral computed tomography scans, and multiplanar reconstruction images were performed on a computer workstation. The structure and parameter of the frontal recess, the sgger nasi cell and adhere style of the uncinate process were recorded precisely. Results: After the reconstruction, a 3D model very close to the true state of the nasal cavity-sinuses cell was obtained, in which parts of the frontal recess can be clearly identified as agger nasi cell, frontal cell and other important structures. Conclusions: This study developed an advanced technique and measurement from 3D reconstructed images of the frontal sinus. The projects resulted in better preoperative subject counseling and in predicting postoperative improvement in clinical status. © 2016, E-Century Publishing Corporation. All rights reserved.
