Chapter 89 - Part D: Reconstruction vs Second Intention: When Fixing the Defect Makes Things Worse

Simini Podcasts Season 1 Episode 82

In this BoardsCast episode, we continue Tobias Chapter 89 - Mandibulectomy and Maxillectomy by exploring one of the most counterintuitive truths in maxillofacial surgery:
Sometimes, the worst thing you can do is “fix” the defect.

After mandibulectomy or maxillectomy, reconstruction may seem like the right choice — but in many cases, reconstruction creates more complications than it prevents. Between tension, necrosis, infection, occlusal mismatch, airway compromise, and mechanical failure, repairing the defect can turn a stable patient into a failing one.

This episode explains when to reconstruct, when not to, and how to decide — exactly what the boards expect you to understand.

You’ll learn:

  • Why reconstruction can worsen biomechanics, occlusion, or airway function
  • When second intention healing provides a superior biologic outcome
  • Flap choices: axial, local, regional, and when each fails
  • The mechanical traps of tension, dead space, and unstable load transfer
  • Why maxilla vs mandible defects heal differently
  • High-risk situations where reconstruction predictably fails
  • Board-relevant case patterns involving partial vs segmental jaw defects

This episode teaches you to stop thinking “fill the hole” and start thinking “optimize function and healing.”
