Objective To explore better approach of resecting tumoraround the anterior skull base and reconstructing the anterior skull base.Methods In November 2004, a 49-years-old male patient with intracranial recrudescent adenoid cystic carcinoma in the anterior cranial fossa was treated using modified transcranial approach. Neurosurgeon and rhinolaryngologist cooperated to excise the tumour completely, and to reconstruct anterior skull base using the pedicle periosteum temproal musculofascial flap(15 cm×10 cm) andthe pedicle flap of aponeurosis of occipitofron talis muscle and muscular fasciae（10 cm×6 cm）.Results After operation, the wound healed by first intention. Complication, such as infection and cerebrospinal rhinorrhea, did not occur. The patient was discharged 10 days after operation, and was followed up for 8 months, no local recurrence were investigated and no scar formed over the face.Conclusion The modified transcranial approachis a relatively novel exposure that enables the skilled cranial base surgeon tosafely resect many malignant lesions previously and to reconstruct the defect of anterior skull base together.

Objective To discuss the surgical method and effect of repair of damage injury in the hands. Methods Of the 29 cases, 22 were males, 7 were females. Their ages ranged from 15 to 31.The size of defect areas ranged from 18 cm×8 cm to 22 cm×10 cm .Along with dorsalis pedis flap, lateral hemi-pulp flap was takenfrom great toe and first web space flap. The second toe was taken from one footto reconstruct the thumb, second and third toe from another foot was used to reconstruct two fingers. The dorsalis pedis flaps were used to cover palm and dorsum of hand. The lateral hemi-pulp flaps from great toe and first web space flapswere used to reconstruct first web space of hand.Results With the 58 combined flaps, 29 thumbs and 58 fingers were reconstructed. Followups was done for 1 to 8 years.All the thumbsand fingers of 29 hands were reconstructed. Their shape and function were well recovered. Conclusion This new surgical method is effective inpreserving the function of injured hand. The function of the injured hands can be preserved by this surgical method, therefore this method is optimal.
目的:探討新的構建心臟解剖系統的方法,為影像醫學、心臟手術和解剖學教學提供參考。方法: 對VHP數據集心臟斷面圖像進行連續追蹤觀察,對分割結果進行三維重建;利用Maya三維動畫軟件對重建心臟進行修正以及對心臟供血過程進行動畫設定。結果: VHP心臟斷面圖像清晰,可清楚顯示心臟各部分組織,心臟重建圖像質量高,心臟供血過程動畫準確、生動。結論:研究采用傳統編程技術與Maya三維動畫軟件相結合進行三維重建的新方法,實現了基于VHP數據集的心臟解剖系統的構建,為影像醫學和心臟手術提供了解剖學參考,也為解剖學教學提供了新的教學軟件。
Objective To evaluate the effect of reconstruction withautograft implantation in total hip arthroplasty(THA) with regional acetabular deficiency. Methods From 1991 to 2000, 39 cases of THA with acetabular deficiency were conducted. Autogenous bone implantation was used to reconstruct the deficient acetabulum. Of the 39 patients, 25 were males and 14 were females. The age ranged from 34 to 62(45.2 on average). There were21 cases of developmental dysplasia resulted deficiency, 14 cases of fracture of femoral neck complicated with head necrosis(10 hips) and fracture of acetabulum(4 hips). The resected femoral heads or autologous ilium were made the wedgeshaped graft and implanted into the deficient acetabulum, which included 12 cases with cement THA and 27 with cementless THA.Of all the cases, 24 were followed up 2 to 10 years(6.7 years on average). Harris scores before operation were 18 to 50(38.1 on average). Results The limbs were lengthened by 2.4 cm on average. No serious complications were observed in these patients. Comparedwith the scores before the operation, the average Harris scores after the operation were 92.1(Plt;0.01)and 86.3(Plt;0.05) in the one-year and the latest follow-up respectively. The rates for the good were 91.7% and 83.3% in the one-year and the latest follow-up respectively.Conclusion The acetabular reconstruction with autograft in THA will bring better stability in those patients with acetabular deficiency. It is of significance in maintaining a long-term function in the replaced hip.
Objective To evaluate the results of chest wallreconstruction (CWR) in patients who underwent chest wall tumor resection accompanying huge chest wall defect. Methods From Jan. 1998 to Mar. 2003, 31 patients underwent CWR. Among them, 20 were male and 11 female. The age ranged from 8 to 72 years.The indications for resection were primary chest wall tumor in 21 patients, lung cancer with invasion of chest wall 6, recurrence of breast cancer 2, radiationnecrosis 1 and skin cancer 1. The number of rib resected was 2~7 ribs (3.6 in average). The defect was 20~220 cm2 (97.1 cm2 in average). Concomitant resectionwas done in 13 patients, including lobectomy or wedge resection of lung 10, partial resection of diaphragm 2, and partial sternectomy 1. Seven patients underwent soft tissue reconstruction alone(latissimus dorsi+greater omentum, latissimusdorsi myocutaneous flap, latissimus dorsi muscle flap), 5 patients bony reconstruction alone(Prolen web), and simultaneous BR and STR were performed in 19 patients(latissimus dorsi, pectorails major, latissimus dorsi+fascia lata, and Prolene web). Results Three patients (9.7%) developed postoperative complications. Postoperative survival period was 6~57 months with a median of 22 months. Conclusion A favorable clinical outcome can be achieved by CWR for the patients with hugechest wall defects that result from resection of chest wall tumors.
Objective To introduce the treatment and clinical result of reconstructing femoral artery with external jugular vein graft. Methods From June 2002 to April 2006, 22 cases of femoral artery defects caused by pseudoaneurysm resection, were reconstructed withexternal jugular vein graft by microsurgical technique. There were 20 males and2 females, aging 25-46 years (mean 31.2 years). The length of femoral artery defects was 5-9 cm, with an average of 6.8 cm. The location was left in 14 cases and right in 8 cases.Results Ten cases achieved healing by the first intention, and 4 cases by the second intention. The other 8 cases need the regional flap repair because the wound splited open and became ulcer. Femoral artery defects were reconstructed successfully and the pulse of dorsal arteries of foot could be felt except 1 case of bleeding of anastomotic rupture. Eighteen patients were followed up 1-30 months, and no pseudoaneurysm recurred. Color ultrasound Doppler detection showed that the external jugular veins took place of the femoral artery defects in 12 cases. Conclusion External jugular vein is stable at anatomy and easy-to-obtain. Its calibre is close to that of the femoral artery. It can be used for reconstructing femoral artery defects as the vein material. The operation is easy and the clinical result is sure.
