Objective:To evaluate the technique of reduction and rigid internal fixation of sagittal maxillary fracture. Methods:15 cases of sagittal maxillary fracture were reviewed. Occlusal guide plates were prepared preoperatively by model surgery analysis in 10 cases; Le Fort ? osteotomy and down-fracture were done in 8 cases; Pterygomaxillary junctions were also separated in the other cases. Internal fixation was applied along the anterior maxillary surface by using microplates in all 15 cases. Results:Anatomically reduction was achieved in all cases; Occlusion of 14 cases was corrected except one case of fracture re-displaced. Conclusion:Orthognathic technique is effective treatment of sagittal maxillary fracture; One microplate applied along anterior maxillary surface may be not enough to ensure the fixation of sagittal maxillary fracture.

Objective: To investigate the principle of diagnosis and treatment of orbital fracture. Methods:114 cases of orbital fractures were reviewed. The incidence of major clinical feature was estimated and the surgical procedures were analyzed. Results:Incidence rate of restricted ocular motility, diplopia and enophthalmos were 63.2%, 62.3% and 59.6% respectively; The incidence of optic nerve injury, lacrimal injury and rupture of the globe was 15.8%,15.8% and 12.3% respectively. 95.6% of the cases were undergone orbital wall reconstruction (artificial bone graft) and 72.8% were received fracture reduction and internal fixation. Conclusion:Restricted ocular motility, diplopia and enophthalmos are major symptoms of orbital fracture and optic nerve injury, lacrimal injury and rupture of the globe are important complications of orbital fracture; Orbital reconstruction is the most popular surgical procedure for orbital fracture and bone reduction and internal fixation is also need for impure orbital fracture.

Objective To study the method and effect of lateral arm free flap in reconstruction of severe atresic eye socket.Methods Forteen cases of severe atresic eye socket,from June,2011 to June,2013,were repaired by lateral arm free flap.The flaps were designed and harvested as drop shape with size about 6 cm × 10 cm and then were removed epidermis except distal 6 cm × 6 cm area which were transferred to orbit for eye socket reconstruction.The remaining fascia and dermis were filled to augment temporal defect.Superficial temporal artery was anastomosed with posterior branch of radial collateral artery in 14 cases and superficial temporal vein was anstomosed with radial collateral vein in 11 cases,with middle temporal vein in 3 cases.Results All 14 cases lateral arm free flaps survived with no donor site morbidity.Followed up for 1 year to 3 years,artificial eye could be fitted satisfactorily and temporal contour improved.Conclusion Lateral arm free flap is a recommendable option for severe atresic eye socket reconstruction because of concealed donor site scar,proper volume,matched vascular caliber and minor donor site morbidity.

Objective To summarize the effect of eye socket reconstruction in patients with severe depressed eye socket combined anophthalmos and to assess the methods of eye socket reconstruction.Methods Forty patients of severe depressed eye socket combined anophthahnos,from Oct,2001 to Mar,2014,underwent eye socket reconstruction in Beijing Tongren Hospital.Thirty four eye sockets were reconstructed with free flap,the scapular flap in 2 cases,the forearm flap in 17 cases,the lateral arm flap in 15 cases.The reversed submental island flap was utilized in 2 patients.The other 4 cases were treated by implant-retained orbital prosthesis.Results All the patients were followed up for more than 2 years.The flaps survived.The artificial eye could be fitted satisfactorily and the appearance of the ill eye socket was improved significantly.The implant-bodies in orbital bone and the prosthesis were stable without peri-implantitis.Conclusions The flap transfer is effective for eye socket reconstruction in patient with severe depressed eye socket combined anophthalmos.The implant-retained orbital prosthesis is also alternative.The treatment choice must be based on the patient 's own conditions.

The vagina contains at least a billion microbial cells,dominated by lactobacilli.Here we perform metagenomic shotgun sequencing on cervical and fecal samples from a cohort of 516 Chinese women of reproductive age,as well as cervical,fecal,and salivary samples from a second cohort of 632 women.Factors such as pregnancy history,delivery history,cesarean section,and breastfeeding were all more important than menstrual cycle in shaping the microbiome,and such information would be necessary before trying to interpret differences between vagino-cervical micro-biome data.Greater proportion of Bifidobacterium breve was seen with older age at sexual debut.The relative abundance of lactobacilli especially Lactobacillus crispatus was negatively associated with pregnancy history.Potential markers for lack of menstrual regularity,heavy flow,dysmenor-rhea,and contraceptives were also identified.Lactobacilli were rare during breastfeeding or post-menopause.Other features such as mood fluctuations and facial speckles could potentially be predicted from the vagino-cervical microbiome.Gut and salivary microbiomes,plasma vitamins,metals,amino acids,and hormones showed associations with the vagino-cervical microbiome.Our results offer an unprecedented glimpse into the microbiota of the female reproductive tract and call for international collaborations to better understand its long-term health impact other than in the settings of infection or pre-term birth.
