|December 1, 1989
Summary
Outer table calvarial bone grafts show moderate resorption (up to 30%) but maintain excellent facial contour long-term. Nasal dorsum and mandible experienced the most significant changes.
Area of Science:
- Craniomaxillofacial surgery
- Plastic surgery
- Regenerative medicine
Background:
- Long-term fate of outer table calvarial bone grafts for facial contouring is not well-established.
- Graft resorption and contour stability are key concerns in reconstructive surgery.
Purpose of the Study:
- To evaluate the long-term outcomes of outer table calvarial bone grafts in facial reconstruction.
- To specifically assess graft resorption and resultant facial contour over time.
Main Methods:
- Retrospective analysis of 850 outer table calvarial bone grafts in 170 patients over 4 years.
- Detailed subgroup analysis of grafts in the nasal region for contour evaluation.
Main Results:
- Excellent facial contour was achieved and maintained in most cases.
- Partial graft resorption, ranging from insignificant to 30%, was observed at most sites.
- Maximum resorption and contour changes occurred at the nasal dorsum and lateral posterior mandible.
Conclusions:
- Outer table calvarial bone grafts provide reliable long-term facial contouring.
- While some resorption is expected, it does not typically compromise aesthetic outcomes.
- Specific anatomical areas like the nasal dorsum require careful consideration regarding potential contour changes.
