얼굴뼈 CT 계측 모형을 이용한 안와벽골절의 재건 = Orbital Wall Reconstruction by Copying a Template(defect model) from the Facial CT in Blow-out Fracture

다국어 초록 (Multilingual Abstract)

Purpose: Recently, orbital wall fracture is common injuries
in the face. Facial CT is essential for the accurate
diagnosis and appropriate treatment to reconstruct of the
orbital wall. The objective of this study was to report the
method for accurate measurement of area and shape of
the bony defect in the blow-out fractures using facial CT
in prior to surgery.
Methods: The authors experienced 46 cases of orbital
wall fractures and examined for diplopia, sensory disturbance
in the area of distribution of the infraorbital nerve,
and enophthalmos in the preoperation and followed 1
months after surgery, from August 2007 to May 2008. Bony
defect was predicted by measuring continuous defect size
from 3 mm interval facial CT. Copying from the defect model
(template), we reconstructed orbital wall with resorbable
sheet (Inion CPS® , Inion Oy, Tampere, Finland).
Results: One months after surgery using this method,
26 (100%) of the 26 patients improved in the diplopia and
sensory disturbance in the area of distribution of the
infraorbital nerve. Also 8 (72.7%) of the 11 patients had
enophthalmos took favorable turn.
Conclusion: This accurate and time-saving method is
practicable for determining the location, shape and size of
the bony defect. Using this method, we can reconstruct
orbital wall fracture fastly and precisely.
