Abstract

Objective: To observe the distribution of the terminal branches of the eleventh and twelfth thoracic nerve(T11, T12) for the anatomical basis and operation key points of the transverse rectus abdominis musculocutaneous(TRAM) flap with T11, T12.

Methods: The anterior abdominal wall was investigated through anatomical dissection in 22 embalmed cadavers.

Results: Cutaneous nerve distribution in the TRAM flap came mainly from T11, T12. They run obliquely between transverse abdominis and obliquus internus abdominis muscle. At the lateral edge of the rectus abdominis, they piece the anterior rectus sheath into the muscle. While supplying the muscle they pass on to supply the anterior rectus sheath and the overlying skin.

Conclusion: It is possible to preserve T11, T12 in the TRAM flap, which would favour rapid return of flap sensation.
