| Popis: | 102 Background and Purpose: The role of primary gingivoperiosteoplasty (PGPP) on the repair of alveolar clefts remains controversial. This study therefore aimed to compare the success of PGPP and secondary alveolar bone grafting (SABG) in patients with unilateral cleft lip and palate (UCLP). Methods: In this prospective study, the postoperative cone-beam computed tomographic scans of 50 children (mean age: 9.8 ± 0.8 years) with complete UCLP who underwent PGPP (n = 25) or SABG (n = 25) were analyzed. Residual cleft defect and unsupported root ratio of cleft-adjacent central incisors were measured and compared between these two methods of alveolar repair. Results: Patients repaired by PGPP presented more need for additional bone grafting than by SABG (28% vs. 4%, p < 0.05). Residual cleft defect and were greater in patients repaired by PGPP than by SABG (305.8 ± 176.5 mm3 vs. 178.6 ± 122.0 mm3, p < 0.05). Patients repaired by PGPP showed more residual palatal coronal and palatal apical defects than by SABG (p < 0.05 and p < 0.001, respectively). Unsupported root ratio of central incisors adjacent to the cleft were not associated with the methods of alveolar repair by PGPP or SABG (1.0 ± 2.9% vs. 1.7 ± 5.2%, p > 0.05). Conclusions: The data suggest that in patients with UCLP, PGPP results in less bone than SABG particularly on the palatal apical portion of the previous alveolar cleft. Clinical success is lower with PGPP when compared with SABG. |
