Intraosseous hemangiomas are uncommon intrabony lesions, representing approximately 0.5 to 1% of all intraosseous tumors. Their description varies from "benign vasoformative neoplasms" to true hamartomatous proliferations of endothelial cells forming a vascular network with intermixed fibrous connective tissue stroma. These commonly present as a firm, painless swelling. Intraosseous hemangiomas present more commonly in females than in males and most likely occur in the fourth decade of life. The most common etiology of intraosseous hemangioma is believed to be prior trauma to the area. They have a tendency to bleed briskly upon removal or biopsy, making preoperative detection of the vascular nature of the lesion of significant importance. There are four variants: (1) capillary type, (2) cavernous type, (3) mixed variant, and (4) scirrhous type. Generally most common in the vertebral skeleton, they can also present in the calvarium and facial bones. In the head, the most common site is the parietal bone, followed by the mandible, and then malar and zygomatic regions. Intraosseous hemangiomas of the zygoma are rare entities with the first case reported in 1950 by Schoenfield. In this article, we review 49 case reports of intraosseous hemangioma of the zygoma, and also present a new case treated with excision followed by polyether-ether ketone implant placement for primary reconstruction.
骨内血管瘤是一种罕见的骨内病变，约占所有骨内肿瘤的0.5%至1%。其描述从“良性血管形成性肿瘤”到真正的内皮细胞错构瘤样增生不等，形成具有混合纤维结缔组织基质的血管网络。这些病变通常表现为质地坚硬、无痛的肿胀。骨内血管瘤在女性中比在男性中更常见，最可能发生在生命的第四个十年。骨内血管瘤最常见的病因被认为是该区域先前受到的创伤。它们在切除或活检时容易迅速出血，因此术前检测病变的血管性质非常重要。有四种类型：（1）毛细血管型，（2）海绵状型，（3）混合型，（4）硬纤维型。一般来说，它们在椎骨骨骼中最常见，也可出现在颅骨和面部骨骼中。在头部，最常见的部位是顶骨，其次是下颌骨，然后是颧骨和颧区。颧骨骨内血管瘤是罕见的病变，第一例由舍恩菲尔德于1950年报道。在本文中，我们回顾了49例颧骨骨内血管瘤的病例报告，并介绍了一例新病例，该病例采用切除治疗，随后植入聚醚醚酮进行一期重建。
