DIEP flap surgery (Deep Inferior Epigastric Perforator flap) is a widely used technique in post-mastectomy breast reconstruction, where abdominal skin and fat are transferred while preserving the rectus muscle. While the vascular outcomes of DIEP flap surgery are well established, I am more interested in the neuroscience perspective, especially regarding sensory recovery and peripheral nerve regeneration in the transferred tissue.
A major challenge is how sensory nerves, particularly intercostal and cutaneous branches, re-establish functional connections after flap transfer. Patients often experience partial, delayed, or variable sensory recovery, suggesting complex mechanisms of peripheral nerve regeneration and neuroplastic adaptation.
From a neurobiological and biomedical engineering perspective, I am curious about:
- How efficiently do regenerating axons integrate into transplanted tissue after DIEP flap surgery?
- What is the comparative role of nerve coaptation vs spontaneous re-innervation in restoring sensation?
- Are there imaging, histological, or computational models that predict nerve regrowth in flap-based reconstructions?
- How does ischemia-reperfusion injury during DIEP flap surgery affect long-term nerve regeneration and sensory outcomes?
I would appreciate any research papers, models, or clinical insights related to peripheral nerve recovery and neurovascular integration in reconstructive procedures.
