Radiological examination of the frontal sinus was conducted before and after frontal sinus operation (Killian's method) with their follow up over a year. Studies of these films revealed that the postoperative state of the frontal sinus could be classified into the following 5 groups.
Group a. postoperative obliteration of the sinus cavity.8%
Group b. postoperative partial obliteration of the sinus cavity61.8%
Group c. partial obliteration with regeneration of the sinus 4.5%
Group d. cnonobliteration but regenerative extension of the sinus cavity18.2%
Group e, unchanged 7.5%
Among these groups, a, b, and e have been reported but the existence of group c and d are new findings which have not been recogniszed by this time.
It has been noted that the incidence of postoperative regeneration of the frontal sinus is more frequent in the young age group and among those witn large frontal sinus preoperatively.
