NCT03976609

Brief Summary

This study evaluates, by means of cone beam computed tomography (CBCT), the alterations in the nasal septum and alveolar cleft volume that occur in cleft lip and palate (CLP) patients after rapid maxillary expansion(RME). 40 unilateral CLP patients (mean age, 11.1 ± 2.2 years) with transverse maxillary deficiency that underwent to RME will be evaluated in this investigation. CBCT images were taken prior to RME (T0) and after the removal of the expander (T1), for adequate secondary bone graft surgical planning. The scans will be used to analyze the effects on the nasal septum, anterior and posterior maxillary basal width (MBW) and alveolar cleft volume.

Outcome Measures

Primary Outcomes (2)

  • Alterations on Nasal septum

    Maxillary expansion performed with 2 activations per day until the tip of the lingual cusps of the maxillary teeth touched the tips of the buccal cusps of the mandibular teeth.

    1 - 2 months

  • Changes in the alveolar cleft dimensions

    Maxillary expansion performed with 2 activations per day until the tip of the lingual cusps of the maxillary teeth touched the tips of the buccal cusps of the mandibular teeth.

    1 - 2 months

Secondary Outcomes (1)

  • Anterior and posterior maxillary basal width changes

    1 - 2 months

Interventions

The patients with maxillary transverse deficiency were treated with Haas expander is a tooth and tissue-borne appliance with a jackscrew located at the anterior region of the arch with its arms bent posteriorly and soldered to the first permanent molar bands. Once activated, the appliances opens the palatal suture and increase the transverse dimension of the maxilla.

Also known as: Palatal expansion technique

Study Population

40 unilateral cleft lip and palate patients (UCLP) (23 male and 17 female), aging from 8 to 14 years old (mean age of 11.1 years ± 2.2). All subjects were in prepubertal or pubertal stage of maturation based on the cervical vertebrae maturation19 assessed on reconstructed lateral cephalograms generated from CBCT.
