Abstract

Surgically assisted rapid maxillary expansion (SARME) is a common treatmenttechnique in the correction of maxillary transverse deficiency. The purpose ofthis study was to evaluate nasal and palatal skeletal changes following SARMEusing Cone Beam Computed Tomography (CBCT) and posterior anterior (PA)cephalograms.Materials and MethodsIn this retrospective study, the radiographic images obtained from 14 patientswith transverse maxillary deficiency before treatment and 6 months after SARMEoperations were evaluated. The changes in nasal bone width and palatal bonewidth were measured on CBCT. The changes in basal maxillary width, nasal cavitywidth and angular measurements were evaluated on PA cephalograms.ResultsNasal floor width was measured at the levels of upper first premolar teeth andmolar teeth which significantly increased following SARME (p=0.005 and 0.017respectively). Palatal bone width between first premolar teeth and molar teethalso significantly increased (p=0.003 and 0.002 respectively). Basal maxillary width(p=0.026), nasal cavity width (p=0.024) and other angular measurements alsosignificantly increased (p<0.05).ConclusionNasal and palatal skeletal transverse dimensions increased following SARME. Dueto the enlargement of the nasal floor and nasal cavity, it is likely to improve air passthrough the nose.
