title: Frequency of surgical correction for maxillary hypoplasia in cleft lip and palate.
abstract: OBJECTIVE
  The aim of this study was to determine the frequency of surgical correction of maxillary hypoplasia in individuals with nonsyndromic cleft lip and/or palate (CL/P) treated at the Center for Craniofacial Anomalies at University of California, San Francisco (UCSF).
  
  
  METHODS
  This is a retrospective cohort study of individuals with cleft lip and/or palate born between 1970 and 1990 who were treated at the UCSF Center for Craniofacial Anomalies. Data were gathered from the UCSF Craniofacial Anomalies Filemaker Pro database.
  
  
  METHODS
  From the database, we collected the following information: age, gender, cleft type, date of orthognathic surgery, and type of osteotomy. The subjects were further subcategorized by cleft type and gender.
  
  
  RESULTS
  A total of 973 individuals with a diagnosis of cleft lip and/or palate were reviewed: 325 subjects had an associated syndrome and 648 were nonsyndromic. A total of 59 of these 648 nonsyndromic cleft individuals (9.1%) required surgical intervention for correction of maxillary hypoplasia: 2/105 (1.9%) for cleft lip, 4/122 (3.3%) for cleft palate, 35/286 (12.2%) for unilateral cleft lip and palate, and 18/135 (13.3%) for bilateral cleft lip and palate.
  
  
  CONCLUSIONS
  The frequency of surgical correction for maxillary hypoplasia in cleft individuals at UCSF Center for Craniofacial Anomalies at 9% was lower than the reported average of 25%.
