OBJECTIVETo measure breast basic dimension by using computer-aided projection fringe system.

METHODSA system has been developed for measuring breast basic dimension based on computer-aided projection fringe measurement and programming software. Plastic manikins breast's SN-N (sternal notch to nipple distance), N-ML (nipple to midline distance), N-N (internipple distance), MBW (base width of breast) and N-IMF (nipple to inframammary fold distance) are measured with this system. At the same time, these items are also measured with routine ruler.

RESULTSThis study indicate that the system has some merits: (1) non-touching measurement; (2) it is very rapid, the patient measured need hold his breath only 0.5 second, and all the time it takes is about 2.5 minutes; (3) the measurement's sensitivity is as high as to 0.6 mm, which meets the clinic requirement entirely; (4) the measurement's accuracy of the system is not significantly when comparing to the routine ruler's.

CONCLUSIONSComputer-aided projection fringe system for measuring breast basic dimension is feasible and advanced.

Objective:To observe the clinical effect of full thickness skin grafting of plastic surgery in the treatment of lower extremity venous extensive ulcer of simple varicosity of great saphenous vein.Methods:A total of 23 patients from January 2011 to December 2016 with lower extremity venous extensive ulcer of simple varicosity of great saphenous vein,who underwent great saphenous vein high ligation,stripping,varicose vein branch ablation and subfascial perforating vein surgery combined with full thickness skin grafting of plastic surgery.Results:The ulcers in 23 cases were all healed.There was no recurrence in six months to two years follow-up.Conclusions:For lower extremity venous extensive ulcer of simple varicosity of great saphenous vein,on the basis of the traditional operation,full thickness skin grafting of plastic surgery can improve the cure rate and decrease the recurrence rate.
