OBJECTIVE: To observe the CT three-dimensional imaging features of the frontal recess region with advanced three-dimensional reconstruction, and develop the real image of the important anatomical structures around the region to conduct surgery.
METHOD: Thirty patients were undergone spiral CT by 16 line high speed spiral CT, and multiplanar reconstruction images using standard three-dimensional reconstruction protocol on a computer workstation. The structure of the frontal recess, the agger nasi cell and adhere style of the uncinate process were observed. The parameter of the important anatomic structure of frontal recess was measured precisely.
RESULT: After the reconstruction, we get the three-dimensional model very close to the true state of the nasal cavity-sinuses cell, in which parts of the frontal recess can clearly identify the agger nasi cell, frontal cell and other important structures. In these patients, the height, width and depth of the agger nasi and frontal sinus were (9.45 ± 3.60)mm, (8.08 ± 3.37)mm, (26.98 ± 6.82)mm and (26.86 ± 9.45)mm, respectively.
CONCLUSION: This study tried to develop the standardized techniques and measurements from three-dimensional reconstructed images of the frontal sinus and to ascertain the usefulness of the frontal sinus in identification of patients. The project results in better preoperative patient counselling and in predicting postoperative improvement in clinical status.
