Obliteration of the frontal sinus is frequently necessary in the appropriate treatment of major craniofacial trauma of the upper third of the face. Successful frontal sinus obliteration requires (1) meticulous removal of the frontal sinus mucosa, (2) permanent occlusion of the nasofrontal duct and (3) obliteration of the denuded cavity. The current techniques include implantation of autologous fat, bone or muscle. These techniques are effective when the appropriate guidelines are respected, but the problems of donor site morbidity, which has been as high as 5%, recipient site morbidity due to the shrinkage of the free graft, and the increase in the operative time must be pointed out. The unique characteristics of lyophilized cartilage, i.e. the low resorption rate and tendency to undergo osseous substitution, justify its use for obliteration of the frontal sinus. The present study reviews 51 patients with obliteration of the frontal sinus due to craniofacial trauma. In none of the patients were there clinical or radiological signs of postoperative mucocele formation. Progressive ossification of the implanted cartilage was verified in most of the patient population.
在面部上三分之一严重颅面创伤的适当治疗中，额窦闭塞常常是必要的。成功的额窦闭塞需要：（1）细致地清除额窦黏膜；（2）永久性闭塞鼻额管；（3）闭塞裸露的腔隙。目前的技术包括自体脂肪、骨或肌肉植入。当遵循适当的指导原则时，这些技术是有效的，但必须指出供区发病问题，其发生率高达5%，游离移植物收缩导致受区发病，以及手术时间增加。冻干软骨的独特特性，即低吸收率和骨替代倾向，证明了其用于额窦闭塞的合理性。本研究回顾了51例因颅面创伤导致额窦闭塞的患者。所有患者均无术后黏液囊肿形成的临床或放射学征象。在大多数患者群体中证实了植入软骨的渐进性骨化。
