Craniofacial osteomas are benign tumors of the skull base, often involving the paranasal sinuses. The frontal sinus is the most common site of involvement, followed by the ethmoid, maxillary, and sphenoid sinuses, respectively. The growth rate is very slow, and it may take many years for osteomas to become clinically apparent. The origin of these tumors has been ascribed to embryologic tissue maldevelopment, trauma, or infection. The tumors are hard and lobulated with an ivory-like appearance, often mixed with a coarse granular component. The bone is compact or cancellous, with vascular or connective tissue components. The complications of osteoma growth are obstruction of sinus ostia, extension into adjacent bones and the intracranial cavity, and displacement of anatomic structures. Management of uncomplicated sinus osteomas is controversial, since surgery involves serious potential risks. When surgery is performed, these tumors can be successfully managed via endoscopic, open, or combined techniques. This article reviews the clinical findings, diagnostic studies, and treatment of 16 patients with paranasal osteomas. The indications for surgical intervention are discussed.
颅面部骨瘤是颅底的良性肿瘤，常累及鼻窦。额窦是最常受累的部位，其次分别是筛窦、上颌窦和蝶窦。生长速度非常缓慢，骨瘤可能需要很多年才会在临床上显现出来。这些肿瘤的起源归因于胚胎组织发育异常、创伤或感染。肿瘤质地坚硬，呈分叶状，外观似象牙，常混合有粗糙的颗粒成分。骨质为致密或松质，伴有血管或结缔组织成分。骨瘤生长的并发症包括鼻窦开口阻塞、向相邻骨骼和颅内腔扩展以及解剖结构移位。单纯鼻窦骨瘤的治疗存在争议，因为手术有严重的潜在风险。进行手术时，这些肿瘤可通过内镜、开放或联合技术成功治疗。本文回顾了16例鼻窦骨瘤患者的临床发现、诊断研究和治疗情况。讨论了手术干预的指征。
