OBJECTIVE: To evaluate the osteogenetic character and repairing maxillary sinus superior wall fractures capability of calcium phosphate cement (CPC) before and after combined with recombinant human bone morphogenetie protein-7(rhBMP-7). METHOD: A 10 mmX5 mm bone defect in the maxillary sinus superior wall was induced by surgery in all 24 New Zealand white rabbits. These 24 rabbits were randomly divided into two groups. The defects were repaired with CPC group (n = 12) and CPC/rhBMP-7 group (n = 12). The osteogenesis of bone defect was monitored by gro'ss observation, histological examination, observation under scanning electron microscope and measurement of ALP activity at 6 and 12 weeks after the implantation. RESULT: In group CPC,new bone was found to form slowly and little by little. In group CPC/rhBMP-7, however, new bone was observed to form early and massively. The ALP activity in group CPC showed significant statistical difference with that of group CPC/rhBMP-7 (P < 0.05). CONCLUSION The CPC/rhBMP-7 composite has osteoconductibility and osteoinductibility, comparing the use of CPC/rhBMP-7 with CPC for the repair of orbital fracture, the former show obvious advantage repairing ability in maxillary sinus superior wall defect.

Objective To discuss with micro-tympanoplastic operation with osteo retention on treating cholesteatomatous otitismedis. Methods Choose 33 cases cholesteatomatous otitis medis patients who toke the tympanoplastic with osteo retention operation,then analyze the postulate and method of the operation, curative effect and complication after operation. Results Follow up with those patients by 12-72 months, and when 3-4 months after operation we endoscopiced the ears, could see that 43 cases of patients ear mastoid process and tympanic sinus were covered with epithelium, those mastoid cavity were well epithelial metaplasia;and the middle ear was separate from mastoid cavity; 39 cases patient of transplant eardrums are heal up (39/43, 90.7%). 2 cases have perforation of the tympanic membrane toke place after 4 months and 6 months with the operation, and it will heal up by anti-inflammatory drug and laser burning, 1 case had tympanic sinus hyperplasia with granulation tissue, and also had grassery juice; after taken anti-inflammatory drug and change bandage for 15 weeks, the symptom disappear. 1 case had grassery juice of operation cavity, after taking anti-inflammatory drug and physiotherapy, the symptom disappear in 24 weeks. After operation the pure tone audiometry shows that air conduction raise (16.8±6.8) dB HL, hearing raise up to:79.1%(34/43). Conclusion Base on right indication of operation choose, taken combined therapy of ambi-operation period, focus of infection are thoroughly cleaning up. Tympanoplastic with osteo retention are treating well with patients of cholesteatomatous otitismedis.

Objective To investigate the safety and efficiency of large-dose alcohol sclerotherapy in treating simple hepatic cyst. Methods Patients with hepatic cyst were divided into two groups. One group with 49 patients was treated with small-dose (<80 ml) absolute alcohol instillation. The other one with 32 patients was treated with large-dose (≥80 ml) absolute alcohol instillation. Blood alcohol concentration (BAC) was recorded right after and 30 rain, 1 h,2 h,3 h after the treatment. Diameter of cyst as a parameter of efficiency was recorded and compared between two groups during 1 year follow-up visit. Results Large-dose group was significantly more efficient in treating hepatic cyst than small-dose group. All BAC records were within the safe range and below the legal limit after drinking. BAC reached its peak 30 minutes after the treatment began and then decreased gradually. A significant correlation was found between BAC and the alcohol dosage. Conclusions Ultrasound-guided sclerotherapy with repeated large-dose absolute alcohol instillation is a safe and efficient treatment for simple hepatic cyst from the perspective of BAC.
