目的探讨颅底部颅内外沟通性肿瘤的分型、手术方法及注意事项。方法 35例颅底部颅内外沟通性肿瘤,按肿瘤沟通的途径及累及的范围将其分为单纯沟通型(颅眶沟通型、颅鼻沟通型、颅颈沟通型等)和广泛累及型。总结各型肿瘤的手术方式及疗效。结果本组病例无手术死亡。单纯沟通型肿瘤多能做到全切除,良性肿瘤预后均较好。广泛累及型手术较为复杂。随访最长6年,其中2例死于肿瘤复发转移。结论合理选择手术入路,术中强调重要结构的保护和颌面及颅底修复与重建,以及多科合作,有助于提高手术治疗颅内外沟通性肿瘤的效果。
Objective To investigate the classification of intracranial and extracranial tumors in the skull base, surgical methods and precautions. Methods Thirty-five patients with intracranial and extracranial tumors of skull base were divided into two groups: simple communicating type (cranio-orbital communicating type, cranial-nasal communicating type, cranio-cervical communicating type, etc.) and extensively involved type according to the way of tumor communication and its coverage. Summary of various types of cancer surgery and efficacy. Results of this group of patients without surgical death. Simple communication can achieve multi-resection of the tumor, the prognosis of benign tumors are better. Extensive involvement of surgery is more complicated. Up to 6 years follow-up, of which 2 died of tumor recurrence and metastasis. Conclusion The reasonable choice of surgical approach, intraoperative emphasis on the protection of important structures and maxillofacial and skull base repair and reconstruction, as well as multidisciplinary cooperation, help to improve the surgical treatment of intracranial and extracranial tumors.
