Detailed description

Abstract Aim of the study: To compare radiographically the morphometric changes in the nasal airway after using three types of rapid maxillary expansion (RME) conventional hyrax (CH), hybrid hyrax (HH) and maxillary skeletal expander (MSE) using cone beam computed tomography (CBCT). Material and Methods: A total sample of thirty CBCT of patients presented with constricted maxilla with mean age of 14±3Y was randomized in to three groups. Group 1 CH, group 2 HH and group 3 MSE. CBCT records were taken before(T1) and after six months (T2) of RME; the Airway was segmented and quantified using software (version 5.3.4.39USA).

Conditions

• Maxillary Retrusion
• Nasal Airway Obstruction

Interventions

Type	Name	Description
DEVICE	CH 4 band	expansion of maxilla and observation improvement of the air way
DEVICE	HH 2 bands	expansion of maxilla and observation improvement of the air way
DEVICE	MSE 2 bands and 4	expansion of maxilla and observation improvement of the air way
