ObjectiveTo analyze clinical efficacy of minimally invasive iliac bone grafting surgery in treatment of alveolar cleft. MethodsForty-four patients with alveolar cleft were included in this study and randomly assigned into control group and observation group, 22 cases in each group. Patients in the control group were treated with traditional iliac bone grafting, and patients in the observation group were given minimally invasive iliac bone grafting. Therapeutic effect in patients of two groups was compared. ResultsThe overall response rate of patients in the observation group (95.45%) was significantly higher than that in the control group (72.72%), while the total incidence of complications in the observation group (13.64%) was significantly lower than that in the control group (68.18%), the differences were statistically significant (P＜0.05). The wound length (0.89±0.11) cm, blood loss (48.45±2.13) mL, the amount of bone mass (12.25±2.19) g, the duration of affecting postoperative activity (1.49±0.29) d, operation time (0.99±0.11) h and postoperative suture removal time (6.98±0.12) d in the observation group were obviously lower than (1.03±0.21) cm, (50.23±3.14) mL, (14.33±2.13) g, (1.68±0.31) d, (1.12±0.12) h and (7.24±0.34) d in the control group, the differences were statistically significant (P＜0.05). ConclusionMinimally invasive iliac bone grafting surgery exerts obvious clinical efficacy in the treatment of alveolar cleft, induces small wound and less blood loss, reduces postoperative complications, promotes early rehabilitation and discharge, and lowers hospitalization cost.
