Hypothesis
Can early postoperative bone scintigraphy accurately assess the viability of microvascular bone grafts in head and neck reconstruction?
Conclusion
Early bone scans are a reliable tool for detecting complications in microvascular bone grafts and can help decide if revision surgery is needed.
Supporting Evidence
- Bone scans detected compromised vascular supply with 92% sensitivity.
- Clinical monitoring had only 75% sensitivity in detecting graft issues.
- 8 out of 60 grafts were lost, indicating a 13.3% failure rate.
Takeaway
Doctors used special scans to check if the bone grafts used in jaw surgery were healthy right after the operation, and they found it worked really well.
Methodology
Bone scintigraphy was performed on 60 patients within the first three postoperative days to assess graft viability.
Limitations
The study is retrospective and may not account for all variables affecting graft viability.
Participant Demographics
60 patients (39 men, 21 women, aged 35 to 82 years, mean age 60 years) undergoing microvascular bone grafting.
