目的:分析异位脑膜瘤在口腔颌面部发病的临床特点及治疗原则。方法:回顾分析1990—2008年口腔颌面外科收治的23例异位脑膜瘤患者的临床资料,总结其临床表现、影像学特点、手术方法及随访情况。结果:①本组病例中位年龄37岁,总体性别差异不明显,但40岁以后女性多于男性。②好发部位依次为咽旁间隙(13例),颞下窝/翼腭窝(5例),颞部(3例);眶部、颊部各1例。③影像学表现与颅内脑膜瘤相同。④23例均行手术治疗,彻底切除17例,部分残留6例。⑤随访12例,复发3例;出现相应神经损伤症状8例。结论:口腔颌面部异位脑膜瘤多见于中青年患者及老年女性;好发于颌面深部间隙,多与颈鞘及后组颅神经关系密切;术前影像学检查有助于诊断;彻底手术是主要的治疗方法,术后并发症主要是相邻的神经损伤。
Objective: To analyze the clinical features and treatment principles of ectopic meningioma in oral and maxillofacial region. Methods: The clinical data of 23 patients with ectopic meningiomas admitted from 1990 to 2008 in oral and maxillofacial surgery were retrospectively analyzed. The clinical manifestations, imaging features, surgical methods and follow-up were summarized. Results: ① The median age of the patients in this group was 37 years old, with no significant difference in the overall sex, but more women than men after 40 years of age. ② The incidence of parapharyngeal space (13 cases), infratemporal fossa / pterygopalatine fossa (5 cases), temporal (3 cases), orbital and cheek in 1 case. ③ imaging findings and intracranial meningioma the same. Thirteen patients underwent surgical treatment, 17 cases were completely resected and 6 cases were partially remained. ⑤ Follow-up 12 cases, 3 cases of recurrence; the corresponding symptoms of nerve injury in 8 cases. Conclusions: Oral and maxillofacial ectopic meningiomas are more common in young and middle-aged patients and elderly women; occur in the maxillofacial deep space, and are mostly closely related to the cranial nerves of the neck and the posterior group; preoperative imaging diagnosis is helpful; thorough Surgery is the main treatment, postoperative complications are mainly adjacent to the nerve injury.
