title: The effect of gingivoperiosteoplasty on facial growth in patients with complete unilateral cleft lip and palate.
abstract: OBJECTIVE
  Gingivoperiosteoplasty performed at the time of lip repair of cleft patients is one kind of alveolar repair. The purpose of this retrospective study was to evaluate the effect of gingivoperiosteoplasty on facial growth of patients with complete unilateral cleft lip and palate (UCLP).
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  Sixty-two consecutive patients with nonsyndromic complete unilateral cleft lip/palate with 5-year-olds' record were included in this retrospective study.
  
  
  METHODS
  All the patients had received nasoalveolar molding treatment before cheiloplasty at the age of 3 to 6 months. Twenty-six patients had gingivoperiosteoplasty performed at the time of cheiloplasty and function as the GPP group. Thirty-six patients did not have gingivoperiosteoplasty at the time of cheiloplasty and function as the non-GPP group.
  
  
  METHODS
  Cephalometry was used to evaluate the facial growth at 5 years of age in the two groups of patients.
  
  
  RESULTS
  Gingivoperiosteoplasty had significant effects on the maxillary position (SNA), intermaxillary position (ANB), maxillary length (PMP-ANS), and maxillary alveolar length (PMP-A) at the age of 5 years. The SNA and ANB angles were larger in non-GPP group than in the GPP group by 3.0 degrees and 2.6 degrees , respectively. The maxillary length (PMP-ANS) and maxillary alveolar length (PMP-A) were larger in the non-GPP group than in the GPP group by 2.1 and 2.9 mm, respectively.
  
  
  CONCLUSIONS
  In patients with UCLP, the sagittal growth of the maxilla would be affected more adversely in the GPP group than in the non-GPP group at the age of 5 years.
