Impaired bone healing after bilateral sagittal split osteotomy (BSSO) can be quantified using volumetric analysis. Increased age and buccal osteotomy site are key risk factors for delayed osseous union.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthognathic Surgery
- Bone Healing Research
Background:
- Bilateral sagittal split osteotomy (BSSO) is a common orthognathic procedure.
- Impaired bony healing post-BSSO presents a significant clinical challenge.
- Identifying risk factors for poor osseous union is crucial for patient outcomes.
Purpose of the Study:
- To quantify osseous union following BSSO using volumetric analysis.
- To identify patient and surgical factors associated with impaired bone healing after BSSO.
Main Methods:
- Volumetric analysis of bone healing using serial cone-beam computed tomography (CBCT) scans.
- Correlation and regression analyses of patient demographics and surgical parameters.
- Inclusion of 36 orthognathic surgery patients undergoing BSSO.
Main Results:
- Volumetric analysis effectively quantified bone healing changes post-BSSO.
- The osteotomy gap site (lingual vs. buccal) significantly impacted volume change (p < 0.01).
- Increased age showed a trend towards significance (p = 0.06) as a risk factor.
Conclusions:
- Advanced age and buccal osteotomy are independent risk factors for impaired BSSO bone healing.
- Volumetric analysis provides a quantitative method to assess osseous union.
- Understanding these risk factors can guide surgical planning and patient management.
