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.

Conditions

  • Nasal Septum; Deviation, Congenital
  • Cleft Lip and Palate
  • Maxillary Hypoplasia

Interventions

PROCEDURE

Maxillary Expansion

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.
