Abstract
Objective
To evaluate the percutaneous hollow needle technique for bone harvest to determine if morbidity, from the bone donor site can be reduced significantly.
Methods
A retrospective chart review was performed evaluating all patients undergoing alveolar bone grafting at our institution from January 1992 through December 1996. Patients who underwent additional major procedures were excluded. Group I consisted of 12 patients in whom the percutaneous technique was utilized. The patients had an average age of 11.1 years (range: 8 to 15 years). Six were male and six were female. One had a bilateral cleft. Group II consisted of 15 patients in whom the conventional open technique for iliac crest bone harvest was used. They had an average age of 13.1 years (range: 7 to 31 years). Six were male and nine were female. Two had bilateral clefts. Minimum follow-up was 6 months. We evaluated intraoperative blood loss, total postoperative analgesia requirement, and length of hospital stay based on a retrospective hospital chart review.
Results
A significant difference was found between the two groups regarding intraoperative blood loss (group I: 83.3 cm3, group II: 208 cm3; p = .0015), postoperative total analgesia requirement (group I:0.04 mg/kg, range: 0 to 0.17 mg/kg; group II: 0.34 mg/kg, range: 0.03 to 0.74 mg/kg; p = .0002), and length of hospital stay (group I: 1.0 days, group II: 2.13 days; p = .0001). There was no significant change in these results when bilateral clefts were excluded.
Conclusion
Iliac bone graft harvest using the percutaneous hollow needle technique results in less blood loss, decreased postoperative pain, and shorter hospital stays compared with the open technique.
