title: Longitudinal study of effect of Hotz's Plate and lip adhesion on maxillary growth in bilateral cleft lip and palate patients.
abstract: OBJECTIVE
  To investigate the effects of infant orthopedic treatment and lip adhesion on maxillary growth of patients with bilateral cleft lip and palate (BCLP).
  
  
  METHODS
  Prospective longitudinal study.
  
  
  METHODS
  The present study was conducted at the Cleft Lip and Palate Center, Harapan Kita Children and Maternity Hospital, Indonesia, and the Department of Oral and Maxillofacial Surgery, Kyushu University Hospital, Japan.
  
  
  METHODS
  The study sample consisted of 53 patients with complete BCLP and 10 noncleft patients with other diseases. Patients with BCLP were divided into three groups: H (-), 11 patients treated without Hotz's plate; H (+), 24 treated with Hotz's plate; and LA-H, 18 treated with lip adhesion and Hotz's plate.
  
  
  METHODS
  Serial dental casts were obtained from each BCLP child at the following four time points: first visit, labioplasty, palatoplasty, and 5 years of age. Each maxillary dental cast was scanned, and the linear and angular dimensions were measured.
  
  
  CONCLUSIONS
  Lip adhesion showed a temporary negative effect. In all patients with BCLP, the surgeries affected the growth of the anterior arch width until the age of 5 years. Collapse of the premaxilla following labioplasty in the H (-) group affected the growth of dental arch length until the age of 5 years. Treatment using Hotz's plate prevented collapse of the premaxilla, and the growth of the arch length was comparable to that observed in the noncleft group.
