Reduction mammoplasty with the modified Benelli round block technique: applied anantomy, technique and long-term follow-up results / 中华医学美学美容杂志

Objective To clarify the applied anatomy of Chinese female breasts,to improve the breast reduction mammoplasty,and to compare the quality of life in women with symptomatic macromastia before and after reduction mammoplasty with the modified round block technique.Methods The blood supply and innervation of the nipple-areolar complex were dissected in 6 Chinese adult females (12 breast specimens).Special attention was paid to the Würinger horizontal septum and the medial and lateral ligaments.The specific beneficial effects of reduction mammoplasty were evaluated with the modified round block technique,and a general questionnaire the Short Form-36 Health Survey Questionnaire (SF-36) was used in this study,which has good reliability and validity.The scores of the patients before and after the surgery were collected respectively.Results In 12 breast specimens,there existed Würinger horizontal septum and the medial and lateral ligaments.The blood supply and nerve innervation of nipple-areolar complex went along Würinger horizontal septum.In all the patients enrolled,SF-36 showed significant higher quality of life after the operation with regard to 7 of 8 investigated domains.Role of emotion increased most significantly.Increased self-esteem and increased personal and public self-consciousness after surgery were observed.Conclusions The incidence of postoperative complications is reduced after using the modified round block technique.Patients have a higher degree of satisfaction overall.These data are further evidence that breast hypertrophy is not solely an esthetic problem.The reduction mammoplasty with the modified round block technique is an ideal technique.

Effects of immunosuppression on post-injury regeneration of peripheral nerve in rats / 第二军医大学学报

Objective:To investigate the effects of immunosuppression treatment on peripheral nerve injury and regeneration in rats.Methods: Forty-nine SD rats were randomly divided into 7 groups: sciatic nerve(in the middle of left thigh) forceps-crushing+cyclophosphane,transecting+cyclophosphane,resecting groups+cyclophosphane,forceps-crushing+normal saline,transecting+normal saline,resecting groups+normal saline,and blank control groups.Cyclophosphane and normal saline were intraperitoneally injected into rats post-operatively.Peripheral nerve regeneration and its related function were assessed by walking track analysis,electrophysiology and histomorphology;immunohistochemistry method was used to evaluate the local autoimmune reactions 12 weeks after operation.Results: Cyclophosphane treated animals had higher scores of sciatic function index(SFI) compared to animals in the corresponding normal saline groups.The electrophysiological(nerve conduction velocity) and morphological examinations showed better regeneration of the myelinated axons in immunosuppression-treated animals compared to the corresponding normal saline groups.The immunohistochemistry showed that the intensities of the local immunological response in immunosuppression groups were obviously lower as compared to the corresponding normal saline groups.Conclusion: There is local autoimmune reaction in post-traumatic nerve regeneration and this autoimmune reaction may influence nerve regeneration.Cyclophosphane treatment can suppress this autoimmune reaction and improve the micro-environment for nerve regeneration.

Anatomy of oriental epicanthus and its correction / 中华医学美学美容杂志

Objective To study epicanthus anatomy in cadavers in order to explore a more ideal technique for the correction of epicanthus. Methods On the basis of epicanthus anatomic dissection in 6 adult cadavers, canthoplasty and a new fixation technique for correcting epicanthus was performed clinically in the following procedures: incising the epicanthal fold and partial inner canthus ligament, pulling the new canthus medially and fixing it on the lateral nasal aponeurosis. Results Anatomic dissection showed that the epicanthus was caused by malposition of the orbicularis oculi muscule. More than 200 patients with epicanthus had been operated on by this technique and 165 of them were available for postoperative follow up for 6 months to 4 years with better cosmetic results. Conclusions This technique has less tissue damage and more favorable postoperative scar. It is a simple and reliable surgical approach for correction of epicanthus.
