Chinese Journal of Tissue Engineering Research 2016;20(20):2992-2999
BACKGROUND:Aclassical orthognathic schemefor mandibular prognathism includespreoperative cephalometric analysis,acquiring modulus, facebow transfer, modelsurgery, making occlusion plate.This process is cumbersome,complex,andproneto have bias. Moreover, orthognathic effects are difficult to be predicted, which is a majordifficultyindoctor-patientcommunication.
OBJECTIVE:To summarize and analyze the use of three-dimensional scanning techniques in the treatmentand diagnosisof mandibular prognathism, including principle, application and relative merits, thusprovidingreference forapplying to theclinic.
METHODS:Papers addressing the use of three-dimensional scanning techniques in thediagnosisand treatment of mandibular prognathism were retrieved by computer in Wanfang and PubMed databases with the key words of “three-dimensional scanning, class III,orthognathic, mandibular prognathism” in Chinese and English, respectively. A total of 48papers were included for review.
RESULTS AND CONCLUSION:Compared with the traditional technology,the three-dimensional scanning technology has high accuracy and efficiency in the diagnosis and treatment of mandibular prognathism, and candirectlycapture the 3D geometry of objects for modeling, colection and measurement of biological data, which provides a reliable monitoring method for postoperative assessment andfolow-up. Compared with the CT,thethree-dimensional scanning technology cannot show the internal structure and separate hard and soft tissues, which should be reasonably chosen according to practical data.

OBJECTIVE:
To evaluate the efficacy and safety of standardized subcutaneous immunotherapy for dust mite in patients with allergic rhinitis.
METHOD:
Using self-control methods, 35 cases with allergic rhinitis were treated with specific immunotherapy for 2 years. Symptom score and visual analogue scale (VAS) score were observed before treatment and 1 years, 2 years after treatment respectively.
RESULT:
The symptoms, signs and VAS score of the 35 patients who were treated with specific immunotherapy after 1 year were significantly reduced than that before treatment, the differences were statistically significant (P < 0.05). The symptoms, signs and VAS score of the patients who completed 2 years' treatment, compared with that of pretreatment and 1 year treatment were significantly reduced, the differences were statistically significant (P < 0.05).
CONCLUSION
Standardized immunotherapy for dust mite is a safe, effective method for patients with perennial allergic rhinitis, which can be used as a routine treatment for allergic rhinitis. To further improve the therapeutic effect, immunotherapy should be continued for at least 2 years.

The ulnar collateral ligament (UCL) of the elbow is the primary stabilizer to resist valgus stress. Its injury is common in overhead throwing athletes, mainly caused by repeated valgus forces, and can cause elbow pain and affect the career of athletes. A common treatment of ulnar collateral ligament injury for overhead throwing athletes is ulnar collateral ligament reconstruction (UCLR). At present, the UCLR techniques have been constantly improved, mainly in graft structure, incision exposure, management of the ulnar nerve, and methods of humeral and ulnar fixation. This paper is to review the anatomy and biomechanics of UCL, as well as techniques, key points, postoperative complications and rehabilitation of UCLR so as to deepen the understanding of UCLR in clinicians.

Objective To explore feasibility of laparoscopic hepatectomy for hepatic hemangioma.Methods Twelve patients were treated by laparoscopic hepatectomy, including left lateral lobectomy in 5 cases and local liver resection in 7 cases. Three cases of hepatic hemangioma associated with gallbladder stone were performed cholecystectomy synchronously. Results Laparoscopic procedures were successfully performed in all 12 cases. The mean operative time was 155 min. The mean blood loss was 230 mL. The mean postoperative hospital stay was 8 days. The pospostoperative recovery was smooth except that 1 case had pulmonary infection. During a follow-up of 6-20 months for 12 cases,there were no recurrence. Conclusion Laparoscopic hepatectomy for hepatic hemangioma is safe and feasibile with good effect under the condition of strict indication selection and experienced surgeons operating.

Objective To report our experiences in difficult laparoscopic cholecystectomy (LC). Methods The clinical data of 201 cases of difficult LC performed from March 2006 to December 2008 were analyzed retrospectively,and the surgical operation approaches were summarized. The cases included 107 patients with pyknotic conglutination around the gallbladder or gallbladder triangle area,38 patients with gallbladder neck stone,11 patients with suppuration or gangrene of the gallbladder,18 patients with atrophy of the gallbladder,and 17 patients with operation history in the upper abdomen. Results The LC was completed in 193 of the cases,the other 8 cases were converted to open surgery. The causes for conversion to open surgery included intractable bleeding at the gallbladder triangle in 3 patients,the gallbladder being covered by stomach,colon and duodenum in 1,gallbladder gangrene in 1,bile leakage resulted from slightly lacerations of the posterior wall at the confluence of the gallbladder and bile duct in 2,and frozen likeness of the gallbladder triangle in 1. The complications of LC included intestinal obstruction (1 case),pulmonary infection with respiratory dysfunction (1 case),and postoperative bleeding (1 cases). No extrahepatic bile duct injury and death occurred in this series. Conclusions For difficult LC,we must abide by the rules as follows: to dissect as far as possible adjoin to the gallbladder;to discriminate the tissues or organs before cutting it;to execute LC in combination with mute and acuminate dissection and antegrade and retrograde approach for resection;to make pneumoperitoneum through a small incision for patients with history of operations in the upper abdomen. Only obey the laparoscopic surgical principle and use correct surgical approaches,can we reduce the incidence rates of complications and conversion to open surgery.

Objective To analyze the clinical diagnosis and therapeutic effect of primary middle lobe lung cancer,in order to provide evidence for clinical diagnosis and treatment.Methods The clinical data of 45 cases of primary middle lobe lung cancer treated by surgery from January 2002 to January 2007 were ana- lyzed retrospectively.The operation style includes:simple middle lobectomy 12 cases(26.7 %),middle or up- per lobectomy 10 cases(22.2 %),right lung total resection 5 cases(11.1%).Chest exploration was done on 2 cases(4.44 %),palliative resection or vedged resection 2 cases(4.44 %).Results 1 case died from lung in- fection and respiratory failure(2.22 %).15 cases with arrhythmia (33.3 %), 1 case with chylothorax were cured after conservative treatment.The survival rate of 1,3,5 year were 82.1%,64.3 %,32.1% respectively. Conclusion The treatment of primary middle lobe lung cancer is dominated by regular lobectomy. It is difficult to perform middle lobectomy,so double or total lobectomy is done generally.Owing to the more postoperative complications, it should be cautious to perform sleeve resection.It should be avoided to do vedged resection for primary middle lobe lung cancer in order to lessen local recurrence.
