Abstract

OBJECTIVES

The objectives of this study was to establish a rationale for repairing large anterior skull base defects with an extended pericranial flap and split calvarial bone graft; to define large anterior skull base defects as those spanning the anterior cranial measuring at least 3.0 x 4.0 cm; and to describe the surgical technique and compare it with alternative strategies. Study design Thirty-four patients underwent anterior craniofacial resection of anterior skull-based tumors of varying histology with reconstruction using an extended pericranial flap and split calvarial bone graft.

RESULTS

The survival of the pericranial flap and bone graft was maintained in 33 of 34 patients. There was 1 episode of postoperative cerebrospinal fluid leak, 1 episode of osteomyelitis of the bone graft and an epidural abscess, and 1 episode of asymptomatic pneumocephalus.

CONCLUSION

Split calvarial bone graft with an extended pericranial flap is an effective technique for reconstructing large anterior skull base defects.

摘要

目的

本研究的目的是为使用扩展帽状腱膜瓣和颅骨劈开骨移植修复大型前颅底缺损建立理论依据；将大型前颅底缺损定义为横跨前颅窝且尺寸至少为3.0×4.0厘米的缺损；描述手术技术并将其与其他替代策略进行比较。研究设计 34例患者接受了不同组织学类型的前颅底肿瘤的前颅面切除术，并使用扩展帽状腱膜瓣和颅骨劈开骨移植进行重建。
