患者女,20岁。于6岁时被石头砸伤右额部,当时诊断右额骨线形骨折,从15岁开始右额骨受伤处隆起一包块,逐渐增大,无明显不适。查体:右额见一约3cm×4cm×3cm肿物,质地硬,与颅骨相连,无压痛(图1)。头颅CT提示右额骨骨瘤(图2)。完善术前准备后全麻下行右额骨骨瘤切除,钛网修补颅骨缺损术。术中见右额骨隆起肿物,约3cm×4cm×3cm,基底与额骨相连续,内板完整,与硬脑膜无黏连。用铣刀在距肿瘤边缘约1cm的正常颅骨处绕骨瘤一圈整块将骨瘤切除,用钛网修补颅骨缺损(图3)。术后病理报告:骨瘤(图4)。术后手术切口愈合好,颅骨修补外形满意,无手术并发症,随访1年肿瘤无复发。 The patient is 20 years old. At the age of six, he suffered a stone injury to the right frontal area. At that time, he diagnosed a right frontal line fracture. From the age of 15 years, he began to inflate a mass in his right frontal bone injury and gradually increased his size. There was no obvious discomfort. Examination: The right front sees a mass of about 3cm x 4cm x 3cm. The texture is hard and connected to the skull without tenderness (Figure 1). Skull CT suggested a right frontal osteoma (Figure 2). After preoperative preparation, the right frontal osteoma was removed under general anesthesia and the skull was repaired with titanium mesh. During the operation, the right frontal bump mass was seen, approximately 3cm x 4cm x 3cm, the basement was continuous with the frontal bone, the inner plate was intact, and there was no adhesion with the dura. The bone tumor was resected with a milling cutter at a normal skull approximately 1 cm from the edge of the tumor around the tumor, and the skull defect was repaired with titanium mesh (Figure 3). Postoperative pathology report: osteoma (Figure 4). The surgical incision healed well and the shape of the skull was satisfactory. No operative complications were observed. No tumor recurrence was observed at the 1-year follow-up.
