Objective To investigate the anatomic basis of the temporal flap pedicled with the orbicularis oculi muscle. Methods The morphology and the blood supply of the orbicularis oculi muscle were studied on 15 cadavers by surgical dissection and vascular cast.Using digital subtraction angiography (DSA),we observed the branches of the superficial temporal artery in 15 patients.The data was then analysed by the computed image analysis system. Results The orbicularis oculi muscle was wide and thin and located superficially.It was supplied by the branches of many arteries and the branches have numerous connections with the branches of superficial temporal artery.The position of the zygomaticoorbital artery was unvaried .The diameter of the artery was up to 1.0 mm. Conclusion Zygomaticoorbital artery is the most important vessel for the temporal flap pedicled with the orbicularis oculi muscle.

AIM:To observe the postoperative effect of the application of expanded artery island skin flap on the treatment of injuries of face.METHODS:Totally 20 patients,who were treated with expanded artery island flap transplantation for face injury at Cosmetic and Plastic Institute,Weifang Medical College,were selected between January 1997 and September 2004.Patients knew the trial and agreed to participate in it.All patients received two phases operation:During the first period of the treatment,according to the different characteristics and requirements of the patients,suitable expander was implanted and water was input regularly.During the second period,the expanded island skin flap was used to cure the injuries on the face or do organ reconstruction.The skin flap was 2.5 cm? 3.5 cm-5.0 cm?7.5 cm,and vessel pedicle was 12.5 cm at most.Follow up was done regularly after operation.RESULTS:A total of 20 patients were involved in the result analysis,no drop out.Follow-up was done for 6-24 months in 20 patients.There were 4 cases of at least 6 months and less than 12 months,7 cases of at least 12 months and less than 18 months,9 cases of at least 18 months and less than 24 months.After expandor implantation in the first period,the expanded skin received skin repair or organ reconstruction in the second period.The healing of the injuries was good and scars of the skin and organ displacement were not clearly seen.Their function was recovered well and shape was ameliorated.CONCLUSION:The expanded island skin flap can provide comparatively large-region flap and long vessel pedicle to increase the angle and flexibility of flap rotation,and make the repair looks closer to the normal area.

Lipedema is secondary to local fat deposition, a disease characterized by the symmetric thickening of lower limbs, mostly occurs in women, especially in adolescence and pregnancy. In its early stage, it could be easily confused with lymphedema. Extensive literature review on primary fat edema in recent years, as well as a summary of the clinical symptoms and signs and diagnosis and treatment of lipedema were conducted, so as to provide a useful reference for clinicians.
