Completed

• Conditions: Restricted Language Development; Unilateral Cleft Lip and Palate; Cleft Palate; Developmental Disabilities; Cleft Lip
• Interventions: Procedure: One stage Palate Surgical repair; Procedure: two stage palate surgical repair

• Registration Number: NCT02329509
• Lead Sponsor: Professor Fernando Figueira Integral Medicine Institute

Brief Summary

The purpose of this study is to evaluate which surgical protocol for treating Unilateral Cleft Lip and Palate (UCLP), a single or two stage repair ( with hard palate late closure) will have less impact in mid facial growth.

The study hypothesis states that a two stage cleft palate repair , with a late hard palate repair will reduce maxillary growth impairment.

Detailed Description

The study is being conducted at CADEFI- Centro de Atenção aos Defeitos da Face do IMIP (craniofacial center) in IMIP-Instituto de Medicina Integral Professor Fernando Figueira-, Recife PE- Pernambuco-, Brazil. All children were and will be operated by the same plastic surgeon in the operating room in IMIP. The sample size was calculated in 64 patients, 32 to GI ( one stage repair) and 32 to GII ( two stage repair, with a hard palate late closure), considering taking a statistical power of 90% with a 5% significance, determined with a difference of at least 25% between the two groups. Note : this sample was calculated for the dependent variable commonly present in patients with unilateral lip and palate cleft : atresia of the dental arches.

The groups are numbered in post op care attendance of the lip repair, according to randomization sequence done in computerized statistical program. The randomization is being held after the first month of the lip repair surgery. The surgeon, and parents or guardians (who have already signed the Informed Consent Form) will not have prior access to information on the type of allocation in each group. Subsequently it will be added in patients chart the record set for the patient group.

\>Study Variables Independent variables:. Group I (palate closure in two surgical times and GII (closure of the palate in a surgical time) also will be considered independent variables age, sex, birth weight and maternal education.

Dependent variables: the presence of postoperative infection, initial and intermediate cleft sizes, dimensional changes of the transverse arch, the evaluation indexes of dental arch relationship(Goslom,Atack Yardsticks) and speech outcomes evaluation grades

Arm && Interventions

Group	Intervention	Description
one stage cleft palate surgery	One stage Palate Surgical repair	Subjects submitted to one stage palate surgical repair after 9 months old and before 24 months old ,
two stage palate repair	two stage palate surgical repair	Subjects submitted to two stage palate surgical repair (first soft palate repair between 6 and 12 months old and hard palate closure at 3 to 4 years old)

Primary Outcome Measures

Name	Time	Method
Maxillary Growth Evaluated by the Atack Yardstick	between 4 to 5 years old	A system that evaluates facial growth , assessing dental arch relationships, and ranking them from 1 to 5, being 1 the best and 5 the worst outcome.Cases are allocated to these categories on a value judgment basis by reference to the anchor groups of the Atack Yardstick. This is performed by external judges, previously trained and evaluated
