[Feasibility of integrating 3D photos and cone-beam computed tomography images used to evaluate changes of soft and hard tissue after orthognathic surgery].
To evaluate the feasibility of integrating 3D photos and cone-beam computed tomography (CBCT) images and to assess the degree of error that may occur during the above process, and to analyze soft and hard tissue changes after orthognathic surgery using this new method. ⋯ Fusing of CBCT and 3D stereophotographic images used as a new method in evaluating soft and hard tissue changes after orthognathic surgery was feasible and accurate. The virtual 3D composite craniofacial models permitted concurrent assessment of hard and soft tissues during diagnosis and treatment planning. Maxillary and mandibular locations had significant association with orthoganthic surgery while the nasal tissue was not simp affected by surgery.

Comparative Study[Arthroscopic all-inside reconstruction for posterior cruciate ligament and popliteus tendon compared with popliteofibular ligament reconstruction: clinical outcome of minimum 2-year follow-up].
To describe the clinical results of a one-stage operation for posterior cruciate ligament reconstruction and a posterolateral corner reconstruction of popliteus tendon reconstruction, compared with an open popliteofibular ligament reconstruction. ⋯ Combined with posterior cruciate ligament reconstruction, anatomical posterolateral corner reconstruction of the popliteus tendon and open reconstruction of popliteofibular ligament showed similar outcomes. This study demonstrated that both posterolateral corner reconstruction techniques were a reliable alternative method in addressing posterolateral corner and posterior cruciate ligament insufficiency of the knee.

[Evaluation and analysis of the tibial coronal alignment after total knee replacement with the extramedullary tibial cutting guided by the tibial tubercle and anterior tibial tendon in Chinese patients].
To evaluate the efficiency of the tibial coronal alignment after total knee arthroplasty with the extramedullary cutting system guided by the tibial tubercle and anterior tibial tendon, and to discuss the potential risk factors for the postoperative malalignment. ⋯ The tibial coronal alignment after total knee arthroplasty could achieve good results with extramedullary cutting guide, by using one third inner-medial tibial tubercle and anterior tibial tendon as a proximal and distal anatomy marker. Postoperative varus might occur in this system, and tibial prosthetic malalignment appeared more often in the patients who suffered a severe deformity before surgery.

Observational Study[Children's intelligence quotient following general anesthesia for dental care: a clinical observation by Chinese Wechsler young children scale of intelligence].
It has been demonstrated that anesthetics exposure may lead to neurocognitive impairment in developing brain of animal models. However, for the limitation that the animal models cannot fully mimic the dose and duration in clinical settings especially for dental general anesthesia, the clinical significance of anesthetics exposure on developing central nervous system remains undetermined. Therefore, we conducted the current study in order to observe the fluctuation of intelligence quotient (IQ) after the administration of dental general anesthesia comparing to that before surgery. We conducted the current study in order to observe the fluctuation of intelligence quotient (IQ) after the administration of dental general anesthesia compared with that before surgery. ⋯ Dental general anesthesia has no negative effect on the intelligence of preschool children, who were treated under general anesthesia by sevoflurane, propofol and nitrous oxide for 2 to 4 hours. The full IQ and performance IQ were slightly enhanced after treatment which can be explained by the memory effect.

[Efficacy analysis of two-stage reverse total shoulder arthroplasty for treating postoperative deep infection after surgeries for proximal humeral fractures].
To evaluate the clinical results of two-stage reverse total shoulder arthroplasty for treating postoperative deep infection after surgeries for proximal humeral fractures. ⋯ two-stage reverse total shoulder arthroplasty was an effective treatment for the postoperative deep infection after surgeries for proximal humeral fractures. The shoulder function was postoperatively improved to a certain degree.
