Objective To investigate reliability of the infra-nipple broken line incision for breast augmentation. Methods From January 2012 to January 2013, 15 patients underwent primary bilateral retromuscular breast augmentation with round textured silicone-gel implants and a novel infra-nipple broken line incision. Preoperatively, a semicircular incision was marked along the inferior base of the nipple. It was then extended bilaterally using two transverse right-angled geometric broken lines within the pigmented areolar skin. Follow-up was performed to evaluate the sensation of nipple-areolar complex, the scar, and the shape and texture of the breasts. Results The average follow-up was 6.7 months. Most of the patients complained of paresthesia of the nipple or breast skin, but transient decreased sensation improved within 3 months. No patients showed permanent sensory changes of the nipple areolar complex at a minimum follow-up of 4 months. The scars were imperceptible in all patients. Conclusion We believe that for selected patients, the infra-nipple broken line incision is a practical and reliable method to achieve aesthetic result.

Background Since its first description in 1841, numerous variations and treatments of Poland＇s syndrome （congenital deficiency of the pectoralis major muscle associated with brachysyndactyly） have been reported. None of the reports, however, involved female Chinese patients. Methods A retrospective study of 24 female patients was conducted to guide the selection of methods of surgical reconstruction. The patients were divided into three groups according to the degree of thoracic tissue development. Type I （mild）： Limited tissue loss which can be treated with simple filling with autologous fat and/or an artificial breast implant. Type II （moderate）： Moderate thoracic tissue hypoplasia where the breast parenchyma can still offer adequate implant coverage. Mammoplasty using a latissimus dorsi muscular flap with an implant was performed in this group. The flap was used to fill the infraclavicular hollow, and the implant was placed in the dual-plane pocket. Type Ⅲ （severe）： Severe thoracic tissue hypoplasia, without sufficient parenchyma to offer implant coverage. A latissimus dorsi muscular flap was used to form a total submuscular pocket in which an implant was placed. Results The numbers of Type Ⅰ, Ⅱ, and Ⅲ patients were 15, 3, and 6, respectively. All of the flaps and injected fat demonstrated good survival. Satisfactory cosmetic results were exhibited during the follow-up period of 1 to 9 years. Conclusions Although this group of patients showed varied conditions, they can be roughly divided into three types according to the degree of thoracic tissue development. In our experience, this classification is simple and useful in choosing the breast reconstruction options.

与游离穿支皮瓣相比,带蒂穿支皮瓣分离技术更加简单,安全系数更高,而且供区畸形更小。近年来,应用带蒂穿支皮瓣技术已经成为乳房再造手术一种新的选择,甚至是一些患者的首选方案。常用的带蒂穿支皮瓣有胸背动脉穿支皮瓣、肋间动脉穿支皮瓣(外侧肋间动脉穿支皮瓣、前侧肋间动脉穿支皮瓣)等,其他可用的选择包括前锯肌动脉穿支皮瓣,腹壁上动脉穿支皮瓣,胸外侧动脉穿支皮瓣等。为了提高手术设计的精确性,术前需要评估穿支血管的质量,并对其定位穿支。皮瓣的设计相比游离皮瓣手术而言,显得更加重要。虽然带蒂穿支皮瓣在乳房再造领域的作用尚不能取代游离皮瓣的金标准地位,但随着"损伤最小化"重建概念的日渐推广,带蒂穿支皮瓣将会成为乳房再造领域里的一种新的趋势。
