1. Recreating the primary defect
|
Not a familiar procedure to the reconstructive surgeon, additional help may be sought. Plan and outcome is based on obtaining true defect |
2. Loss of tissue plane
|
Results from surgery and radiation. Extreme caution is exercised to avoid injury to underlying vessels |
3. Soft-tissue contraction
|
Seen when no or soft tissue alone was used without splinting the mandible. The defect needs more tissue than anticipated |
4. Measuring a true bone gap
|
Mandible requires trimming on edges and avoiding previous fixation points |
5. Choice of suitable recipient vessels |
Should be the first step and often contralateral neck is explored. Planning the orientation of the flap is based on site of anastomosis and pedicle length |
6. Absence of condyle
|
Soft-tissue pocket at glenoid helps support ascending part of neomandible. Anchoring may be used |
7. Re
establishing contour and occlusion
|
Use of previous reconstruction plate or CT-guided 3D printing templates |
8. Non
pliable skin and hypovascularity
|
Watch for skin necrosis at the most distal ends and chin. Additional skin or secondary closure is option |
9. Neck defect closure
|
Loose approximation avoids pressure and allows drainage |
10. Measure of success |
Goals are similar to primary but in reality limited to survival of the flap and amelioration of symptoms |
