The most commonly used techniques for frontal sinus obliteration involve the implantation of an autogenous tissue graft: either fat, muscle or bone. Lyophilized allogenic cartilage due to its unique properties, such as the tendency to ossification and resistance to volume reduction, can be used as the material of choice for sinus obliteration. A clinical and radiological study of 66 patients operated on for frontal sinus fractures, between January 1 1988 through December 31 1995 was undertaken. Variables recorded included the aetiological factors, the clinical and radiological fracture features with the corresponding treatment modality, the association of frontal sinus fractures with intracranial involvement, the early and late postsurgical complications and the correlation between pre- and postoperative radiological findings. Obliteration of the frontal sinus with lyophilized cartilage chips was performed in 51 (77.3%) patients. The postsurgical evaluation showed no major complications. Revision of the frontal sinus was only required in one patient. The radiological findings verified the progressive calcification of the obliterated sinus. Allogenic lyophilized cartilage implantation offers distinct advantages in cases of severe frontal sinus trauma:1.There is nearly unlimited availability of the material. 2.There is no need for a second operation field with the associated potential donor site morbidity. 3.The operation time is reduced due to the avoidance of a second operation on the donor site. |
