Taking dual-plane breast reconstruction as an example, preoperative marking lines are drawn to indicate the contour and inframammary fold of the reconstructed breast. A 4-5 cm axillary incision is placed one finger-breadth below the axillary apex. After making the skin incision, the plane between the pectoralis major and minor muscles is identified and dissected, extending approximately 2 cm below the previous mastectomy horizontal scar. The inner and lower parts of the pectoralis major muscle were then separated. Proceed to the subcutaneous layer and continue to dissociate the flap until it reaches the pre-designed folds and the breast boundary. The use of the TiLOOP® Bra depends on the thickness of the patient's flap. Finally, the prosthesis is placed behind the pectoralis major muscle for breast reconstruction.",[9],null,[21,26],{"name":22,"role":23,"phone":24,"phoneExt":19,"email":25},"Zhenggui Du","CONTACT","+86 13880768222","docduzg@163.com",{"name":27,"role":23,"phone":28,"phoneExt":19,"email":29},"Xiaoman Cao","+86 17208274564","cxm102938@163.com",[31],{"facility":32,"status":19,"city":33,"state":34,"zip":35,"country":36,"countryCode":37,"cosmosGeoPoint":38,"geoPoint":43,"contacts":19},"West China hospital of Sichuan University","Chengdu","Sichuan","610000","China","CN",{"type":39,"coordinates":40},"Point",[41,42],104.06667,30.66667,{"lat":42,"lon":41},{"type":45,"investigatorFullName":46,"investigatorTitle":47,"investigatorAffiliation":5,"oldNameTitle":19,"oldOrganization":19},"SPONSOR_INVESTIGATOR","Du Zhenggui","Deputy director.
