An Illustration of the Osteoplastic Operation of Frontal Sinuses and Ethmoidal Sinuses

Abstract

The author formerly reported on his new method of osteoplastic operation of frontal sinuses and anterior portion of ethmoidal sinuses in “The Otologia Fukuoka”,(Vol 3 No.3 57).
The author has since been receiving quesions from many following experimenters about his operation method. These questions are almost concerning the technique of loosening a bone graft, or the ugly scar left on the face, the questioners seem to confuse this with the method of Killian.
The keypoint of this operation is to loosen a bone graft properly, but that of the method of Killian is to remove the mucous membrane completely through a small bone aperture. If this important process is accomplished succesfully, the operation is as good as accomplished. Therefore, the operator must concentrate his whole energies for this purpose without any attention to the expenditure of time.
Further more, if the 5 rules emphasized by the author are strictly observed, this process can be accomplished easily and properly.
The rules are:
1. The keypoint of this operation is to loosen a bone graft.
2. The following 3 rules for chiseling should be observed.
a. The chisel should be kept at 45 degrees to the bone surface.
b. Chisel-marks should be left zigzag in chiseling.
c. The power driving the chisel should be uniform.
3. The operator should use sharp chisel specially made for this operation.
4. Sufficient time should be spent for loosening a bone graft.
5. The operator should be in no hurry if much time is spent.
To satisfy the questioners, the author has illustrated the method of operation exhaustively sb that even a beginner may accomplish this operation.
He also repots the postoperative treatments, results and complications of this operation based on his experiences of 300 patients.
