目的:探讨采用改良带蒂颅骨膜复合瓣修复鼻颅底沟通肿瘤术中缺损并发脑脊液漏的临床效果。方法:回顾7例鼻腔鼻窦肿瘤术中致前颅底骨质缺损脑脊液漏7例的治疗效果,其中1例良性肿瘤,6例恶性肿瘤。转移的组织瓣以一侧颞浅动脉额支辅以同侧眶上、滑车上动脉为蒂。结果:7例患者切口一期愈合,1例因术后1个月放疗致游离额骨瓣部分坏死,经颞部切口引流愈合。组织瓣在鼻腔内组织面光滑。结论:改良带蒂颅骨膜复合瓣组织量大,血供可靠,制作简单,可以成为修复鼻腔鼻窦肿瘤术中前颅底缺损合并脑脊液漏的重要方法。
Objective: To investigate the clinical effect of using modified pedicled periosteal composite flap to repair nasal skull base defects in intraoperative tumor with cerebrospinal fluid leakage. Methods: Seven cases of nasal sinus surgery were retrospectively reviewed. Seven cases of cerebrospinal fluid leakage caused by anterior cranial basement defect were retrospectively reviewed. One case was benign and six cases was malignant. Transplantation of the flap to one side of the superficial temporal artery frontal support with ipsilateral supraorbital, pedicle artery pedicle. Results: The wounds of 7 patients were healed in one time, and one patient was partially free from the frontal bone flap due to radiotherapy one month after operation. The wounds healed by temporal incision drainage. Tissue flap in the nasal tissue smooth surface. CONCLUSION: The modified pedicled periosteal composite flap has a large amount of tissue, reliable blood supply and simple manufacture. It can be an important method for repairing the anterior skull base defect and cerebrospinal fluid leakage during nasal sinus surgery.
