Abstract
Long term serial radiological examinations were conducted on the healing process following radical operations for chronic frontal sinusitis.
The Author acknowledged the following four facts:
1) When operations were performed bilaterally for chronic frontal sinusitis, the heavily involved side obliterated and healed earlier than the contralateral side.
2) In case a frontal sinus was not evenly diseased, the heavily involved area obliterated and healed quicker than the less diseased area.
3) The older the lesion was, the easier it healed.
4) Stimuli applied for a certain postoperative period enhanced the obliteration and the healing.
Above mentioned facts should be kept in mind in making therapeutic plan and in selecting plombage materials. The author presented representative cases with pertinent discussion.
