Purpose

Surgically assisted rapid maxillary
expansion (SARME) is a common treatment technique in the correction of
maxillary transverse deficiency. The purpose of this study was to evaluate
nasal and palatal skeletal changes following SARME using Cone Beam Computed
Tomography (CBCT) and posterior anterior (PA) cephalograms.

Materials and Methods

In this retrospective study, the
radiographic images obtained from 14 patients with transverse maxillary
deficiency before treatment and 6 months after SARME operations were evaluated.
The changes in nasal bone width and palatal bone width were measured on CBCT.
The changes in basal maxillary width, nasal cavity width and angular
measurements were evaluated on PA cephalograms.

Results

Nasal floor width was measured at the
levels of upper first premolar teeth and molar teeth which significantly
increased following SARME (p=0.005 and 0.017 respectively). Palatal bone width
between first premolar teeth and molar teeth also 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 also significantly increased (p<0.05).

Conclusion

Nasal and palatal skeletal transverse
dimensions increased following SARME. Due to the enlargement of the nasal floor
and nasal cavity, it is likely to improve air pass through the nose.
