The authors used lyophilized cartilage in plate, bar, chip or powder form in elderly patients. The transplant was also utilized in managing defects resulting from the removal of jaw cysts, bone tumours, etc. Furthermore, the authors treated bone defects of the anterior wall of the maxillary sinus and of the hard palate as well as oro-antral perforations, infected wounds of the soft tissues and inflammatory bone processes. The patients in question had been treated in the surgical service during the years 1959--1975. The authors observed in elderly patients pathological alterations of the capillaries, haemorrhagic tendency and impairment of the blood-clotting mechanism. Furthermore, they found that the granulation tissue was of poor quality. In these cases they used cartilaginous tissue in powder form which promotes the formation of granulation tissue well supplied with blood. In the patients mentioned, the authors also utilized surgical adhesive, namely after tooth extractions and in managing their complications.
作者在老年患者中使用了冻干软骨，其形态为板状、棒状、碎屑状或粉末状。该移植物还用于处理因切除颌骨囊肿、骨肿瘤等导致的缺损。此外，作者还治疗了上颌窦前壁和硬腭的骨缺损以及口鼻瘘、软组织感染伤口和炎性骨病变。这些患者在1959年至1975年期间接受了外科治疗。作者观察到老年患者存在毛细血管的病理改变、出血倾向和凝血机制受损。此外，他们发现肉芽组织质量较差。在这些病例中，他们使用了粉末状的软骨组织，其能很好地促进血供丰富的肉芽组织形成。在所提及的患者中，作者还使用了外科粘合剂，即在拔牙后及其并发症的处理中使用。
