Objective:To seek the possibility of using internally installed curved mandibular distractor to repair the partial mandibular curved defect.Methods:A curved mandibular defect was sectioned in each of 3 adult dogs.The distractor designed by our own group based on the steel ball conducted force was implanted.After 7 days of latency,the distraction was performed at the rate of 0.5 mm × 2 times per day,followed by 3 months consolidation period.The osteogenesis was evaluated by general observation,X-ray examination and HE staining.Results:No complication was observed after operation and during distraction.The new bone healed well into a curved shape.The X-ray examination revealed that the transport disc moved along with the predesigned rail curve.HE staining clearly showed neo bone formulation zone between the mature trabecular and connective tissue.Conclusion:The internal distractor based on the steel ball conducted force can realize the curved distraction osteogenesis of posteriormandibular.

OBJECTIVE To study effective and convenient method for paraffin oil sterilization.METHODS By using carrier qualitative germicidal test,to compare pressure steam sterilization,dry heat sterilization and cobalt-60(gamma)-ray radiation sterilization to test the sterilizing effect and operating procedure.RESULTS Pressure steam sterilization was unable to achieve 100% sterilizing effect,whether we extended the time or use the intermittent(sterilization).After dry heat or radiation sterilization processes,no microorganism was found.CONCLUSIONS Effect of sterilization with dry heat or radiation sterilization is trustable,but its packing,operation and equipment are requested strictly,and pressure steam sterilization may be not good for paraffin oil.

Objective To evaluate the quality of examination papers of otolaryngology among students of grade 2007 in the first clinical college of Chongqing Medical University.Methods Totally 202 copies of examination papers of otolaryngology from grade 2007 students in our college were taken as research references.SASS 15.0 software was used to statistically analyze total score of every student and score of each question.Mean score,standard deviation,difficulty coefficient and discrimination coefficient of each question were counted and normality test was conducted.Results Scores were in negative skewness distribution,with mean score of 80.9,standard deviation of 10.9,the lowest score of 56.5,the highest score of 98.0,difficulty coefficient of 0.781,and discrimination coefficient of 0.308.Conclusions Examination papers are well designed and discriminated and can objectively reflect students' command of the course.However,distribution of sores is unreasonable and examination paper is relatively easy to complete,indicating the weakness in the teaching process.

BACKGROUND: There are many methods for repairing the hemifacial atrophy, the most common is preparing plaster facial mold of the patient, with wax piled on the surface to restore the patient's facial shape, and wax pattern serves as a reference of surgical pad. However, the therapeutic effect for the correction and treatment is not satisfactory due to varied abnormality and difficult plans.OBJECTIVE: To discuss the feasibility of manufacturing underlay for the treatment of hemifacial atrophy using computer-assisted design and rapid prototyping technology. METHODS: Skull of the hemifacial atrophy patient was scanned with Picker 6000 SCT, and the data obtained were processed in Voxel Q image workstation for 3-D reconstruction with volume rendering technique. After the interval lamination, the images were downloaded at 0.4-mm interval in a BMP format using CuteFTP 4.0 software. Then the transaxial 2-D image data were converted into digitized 2-D contour data by using image processing software developed by experimental team through a series of processes, including filtering, screening, noise reduction, and distortion correction. The edges and contour of the images was extracted to obtain a vector diagram of facial cranial cortical bone contour line. The digitized data were inputted into image processing software of Surfacer 9.0 for vector superposing, thus the 3-D wire frame and solid images of skull could be reconstructed. According to mirror-image symmetry relation, the point-cloud data of facial bone on the normal side was duplicated to the atrophied side. Thus a 3-D model of the underlay was produced between the atrophied bone and the mirror image of normal side. In order to compensate the atrophy of soft tissues, the model was designed 1.5 mm thicker. After the three-dimensional Surfacer data on the CAD were re-stratified, the contour editing of the underlay and the supporting set of prototype were completed in RpDataRepare, forming RP files and creating underlay template through rapidly output of the processing file for rapid prototyping required, as a reference of surgical procedures.RESULTS AND CONCLUSION: The 3-D solid model of the patient skull bone surface contour was obtained and simulacrum of the underlay was prepared with computer assistance and rapid prototyping. According to the simulacrum, the operation was carried out and got a satisfactory result. The manufacture of underlay for the treatment of hemifacial atrophy could be accomplished by computer assisted design and rapid prototyping in a highly precise and rapid manner. It is a promising technique in the field of individualized underlay making in craniofacial surgery.

BACKGROUND: A three-dimensional spiral computer tomography can display stereoscopic pictures with multi angles on films or computer screens. However, it is hard to display complex three-dimensional anatomical morphology on two-dimensional films or computer screens. Thus, three-dimensional models are needed in craniomaxillofacial surgery simulation or conceptual design.OBJECTIVE: To establish a three-dimensional skull model using spiral computer tomography data and to explore its application in craniofacial surgery.METHODS: Skull of the patient was scanned with Picker 6000 spiral computer tomography with 2.0 slice thickness and 1.0 pitch,and the obtained data were treated in Voxel Q image workstation for three-dimensional reconstruction with volume rendering technique. After having been downloaded to personal computer at 0.1 mm interval, the transaxial two-dimensional image data were converted into two-dimensional digitized contour data by using image processing software developed by the experimental team. The wire frame and solid images of craniofacial triangular facets could be reconstructed when the digitized data were inputted into image processing software of Surfacer 9.0.RESULTS AND CONCLUSION: The three-dimensional wire frame and solid image of skull was reconstructed and computer aided design for plastic operation was accomplished on it. Then the simulacrum of underlay was obtained by rapid prototyping technology. A three-dimensional skull model could be established using spiral computer tomography data. It might play an important role in the diagnosis and treatment of tumors, injuries and abnormality in craniofacial surgery.
