| pubmed-article:738221 | pubmed:abstractText | The radical operations of the paranasal sinuses with total removal of the diseased mucosa very often produced postoperative disability due to scar formation and nerve irritation. A new concept of endonasal sinus surgery is based on the reestablishment of paranasal draining, reventilation, and preservation of the lining mucosa. This became possible by a strictly endonasal approach using angle-optic endoscopes for the optical control of manipulations. The principles of endonasal antrostomy, ethmoidectomy, and infundibulotomy are outlined, and their preliminary results are given. The importance of long-range postoperative local treatment is emphasized. | lld:pubmed |
