A retrospective study was performed to evaluate the rate of infection in free and osteoplastic bone flaps after craniotomy. Two hundred and two craniotomies were performed in 98 cases of tumour, 35 cases of trauma and 69 cases of vascular disease. The overall incidence of infection was 6.4% (13 cases). The infectious agents were Staphylococcus aureus in four cases; Pneumococcus and gram-positive rods each in one case. In seven cases no infectious agent was identified. In 127 cases with free bone flaps eight (6.3%) were infected, and in 75 cases with osteoplastic bone flaps five (6.7%) were infected. One of five (20%) osteoplastic and four of eight (50%) free bone flaps had to be removed in order to accomplish healing, suggesting that an osteoplastic bone flap may be preserved more often in cases of infection.
进行了一项回顾性研究，以评估开颅术后游离骨瓣和塑形骨瓣的感染率。对98例肿瘤、35例创伤和69例血管疾病患者进行了202次开颅手术。感染的总体发生率为6.4%（13例）。感染病原体为金黄色葡萄球菌4例；肺炎球菌和革兰氏阳性杆菌各1例。7例未鉴定出感染病原体。在127例游离骨瓣病例中，8例（6.3%）发生感染，在75例塑形骨瓣病例中，5例（6.7%）发生感染。为实现愈合，5例塑形骨瓣中有1例（20%）、8例游离骨瓣中有4例（50%）不得不被移除，这表明在感染病例中塑形骨瓣可能更常得以保留。
