ABSTRACT
OBJECTIVE@#To observe the therapeutic effect of tympanoplasty with soft-wall reconstruction of ear canal for chronic otitis media with cholesteatoma.@*METHOD@#Seventy-three patients (76 ears) suffering from chronic otitis media with cholesteatoma were treated with canal wall down mastoidectomy with tympanoplasty. Postauricular myo-periosteal flap was used to the soft-wall reconstruction of ear canal, and the cavityplasty of auricular concha was not performed. The auricular bone prosthesis was made of the autogeneic mastoid cortical bone or residual incus. The postoperative modality and the function of external auditory canal and the postoperative hearing and the postoperative complications were observed.@*RESULT@#The mean dry ear time was (21.1 +/- 3. 1) days after surgery in this study. The postoperative modality of external auditory canal was normal on the whole. The patients were followed up between 6 months and 24 months after surgery. The postoperative average air conduction hearing was improved by (14.5 +/- 6.1) dB HL.@*CONCLUSION@#Tympanoplasty with soft-wall reconstruction of ear canal using the postauricular myo-periosteal flap can recover the modality and function of external auditory canal on the whole, and the cavityplasty of auricular concha is not needed. The postoperative hearing can be improved by this technique satisfactorily.

Objective To study the application of multidector spiral CT(MSCT) in the diagnosis of pulmonary embolism(PE).Methods The clinical and MSCTPA data of 15 cases with suspected PE were analyzed retrospectively.Results Of 15 cases,14 cases(93.3%)were diagnosed as PE.849 branches(82%) of pulmonary arteries were showed in 1035 branches.PE was detected in 130 branches(15.3%) of 849 branches of pulmonary arteries.438 branches(73%) were showed in 600 branches of subsegmental pulmonary arteries,PE was showed in 43 branches(9.8%)of 438 branches.Direct signs of PE included central filling defect in 3 cases;eccentric filling defect(n=9);embolism attached to the wall of host artery(n=2) and total occlusion of the pulmonary arteries(n=3).Indirect signs includedmosaic sign in 1 case;subpleural infarction(n=3);pulmonary hypertension(n=5);Westermark sign(n=8) and pleural effusion(n=6).Conclusion MSCTPA is a fast,effective,security and non-invasive diagnostic method for PE,it may replace the pulmonaryangiography and will be the first choice for diagnosis of PE.
ABSTRACT
Objective To investigate the CT manifestations of pulmonary sclerosing hemangioma (PSH), and improve the CT diagnostic accuracy of the disease.Methods The CT manifestations of 5 cases with pulmonary sclerosing hemangioma which were proved by pathology were analyzed retrospectively. Results Solitary pulmonary nodule was demonstrated in all 5 cases with clear demarcation on CT. The nodule was smooth and homogeneous in density in 4 cases, and was slightly irregular with cavity in another case. After intravenous contrast administration, all the lesions were homogeneously enhanced, similar to the nearby blood vessels. The vessels linked with the lesions were found generally.Conclusion The CT is helpful for the diagnosis of PSH.
ABSTRACT
Objective To analyse CT signs of giant cell tumor of bone.Methods CT appearances of 42 cases of giant cell tumor of bone were reviewed.All patients were pathological proven.Results (1)Two kinds of bone destruction were seen in all ases:expansive cystic destruction and osteolytic destruction.The anterior was predominantly.(2)Most of our patients haven't bone septations in their tumors (95.2%).(3)Bone crests were usually seen in our study(63.2%).(4)Complete or incomplete sclerotic borders existed in 44.7% of all cases.(5)The inner bone soft tissues were heterogeneously in most of the patients.Fluid-fluid level can be seen in 5 cases (11.9%).(6)The outer-bone soft tissue masses were demonstrated in the majority cases with discontinuous bone shell.Conclusion CT may deepen our understanding and add imaging signs about giant cell tumor of bone;Which can enhance our diagnostic and differential diagnostic capability.
ABSTRACT
Objective To investigate the clinical efficacy of percutaneous vertebroplasty (PVP)for vertebral metastases.Methods 40 cases with 46 vertebral body metastases underwent PVP under the guidance of fluoroscopy or CT.The analgesic effect,vertebral body stability and complications after operation were observed.Results The successful rate of puncture was 100%.The pain relief was demonstrated in all cases(complete relief in 30 cases,partial relief in 8 cases,mld relief in 2 cases) after operation 1 to 3 days.All involved vertebral bodies had good stability.Imaging analysis demonstrated that the metastatic area was completely well-distributed filling and reinforce by polymethymethacrylate(PMMA) in 26 vertebra of 24 cases.The other 20 vertebral of 16 cases were great part filled by PMMA.There were no severe complications both during operation and post-operation.The treating effect was satisfying in the following 1 to 3 months.Conclusion PVP is one of the efficacious way to alleviate pain of vertebral metastases,and it can reinforce the stAbility of involved vertebral body.
ABSTRACT
AIM: To compare the ginsenoside Rb 1 content in different granularity of Radix Panacis Quinquefolii in order to confine Chinese medicine by ultramicro powder technique. METHODS: HPLC was used to determine ginsenoside Rb 1 in micropowder of Radix Panacis Quinquefolii.RESULTS:The contents of ginsenoside Rb 1 in micropowder of Radix Panacis Quinquefolii pulverized in normal and low temperature were increasing with particle size reduction, and the content in low temperature pulverization was distinctly higher than that in normal temperature pulverization. CONCLUSIONS: Low temperature pulverization of Radix panacis Quinquefolii is superior to processing at temperature.
