Complete healing of the chronic frontal sinusitis is resulted from osseous obliteration but there are few method to be competent for this purpose.
Basing our animal (dogs) experiment, we obtained a somewhat complete result from the clinical experiments using bone transplantation into the frontal sinus.
Material and method: Patients of chronic frontal sinusitis (55 sides of 47 cases) and frontal mucocele (2 sides of 2 cases) were operated as follow. Pathologic mucous membrane of frontal sinus were completely removed after wide opening of the osseous anterior wall of the frontal sinus and the autogenous iliac bone fragment (cortical and cancellous) were transplanted into the frontal sinus.
Result: 55 sides of 47 cases were completely healed without infection and only 2 sides of 2 cases were infected after operation. But one case was healed after one week by the penicillin injection into the infectious region. The other case showed reinfection after a bone transplantation but the sinus was remarkably reduced and healed by the proliferation of the granulation tissue.
From the above results the autogenous bone transplantation is an excellent operation to obliterating completely osseous operated frontal sinus, shorting the healing process, remaining no ugly looking and especially preventing the recurrence of the disease.
