观察用钛网结构修复下颌骨的患者40例,男22例,女18例,年龄14～75岁。下颌骨缺损原因:良性肿瘤切除17例,火器伤13例,恶性肿瘤切除10例。单独用钛网结构修复21例(第1组),钛网结构和自体髂骨联合使用19例(第2组)。术后2～2.5周X线检查,两组均恢复了下颌外形,修复体位置好,植骨块和钛网结构紧密接触。术后6月,临床检查局部无炎症,修复体固定牢靠。X线检查,修复体完整无损,没有移位。 术后1.5～2年,第1组出现并发症者11例,其中9例金属结构穿透皮肤或口腔粘膜。这9例均为恶性肿
40 cases of mandibular reconstruction with titanium mesh structure were observed, including 22 males and 18 females, aged from 14 to 75 years. Causes of mandibular defects: benign tumor resection in 17 cases, firearm injury in 13 cases, malignant tumor resection in 10 cases. Twenty-one patients (group 1) were treated with titanium mesh alone and 19 patients with titanium (titanium mesh) and autologous ilium (group 2). X-ray examination was performed 2 to 2.5 weeks after operation. The mandibular shape was restored in both groups, and the position of the prosthesis was good. The bone graft and the titanium mesh structure were in close contact. After surgery in June, no local inflammation of the clinical examination, prosthesis fixed firmly. X-ray examination, restoration intact, no shift. After 1.5 to 2 years, 11 cases developed complications in group 1, 9 of which penetrated the skin or oral mucosa. All 9 cases were malignant
