胸大肌腹部的显微外科解剖学研究

目的：为在整形外科领域中更加合理和有效地使用胸大肌提供解剖学依据。方法：对12例（24例）灌注红色乳胶的成人尸体标本的胸大肌血管、神经进行显微解剖观察和测量。结果：胸大肌腹部在形态学上具有相对的独立性，全长22.7cm，中段宽6.0cm，中段厚3.3mm，腱长3.2cm；动脉外径1.98mm，起点至肌门长度4.9cm；神经的横径1.71mm，从起点至肌门的长度5.5cm。结论：单独地使用胸大肌腹部不仅存在可能性，而且具有可操作性。

Applied anatomy of the abdominal portion of the pectoralis major

Objective: To provide anatomical data for rationally and effectively using the pectoralis major at the plastic surgery. Methods: The blood vessels and nerves on pectoralis major muscles were measured and studied in 12 adult cadaveric specimens. Results: It was found that the abdominal portion of the pectoralis major was relatively independent and its average length was 22. 7 cm, middle width 6. 0 cm, middle thickness 3. 3 mm, length of ligament 3. 2 cm; the outer diameter of its artery was 1. 98 mm and the length form the artery's origin to its entrance to the muscular was 4. 9 cm; the diameter of its nerves was 1. 71 mm and the distance from the nerve's origin to its entrance to muscular was 5. 5 cm. Conclusions: The abdominal portion of the pectoralis major can be used in plastic surgery as a single unit.
