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.
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.
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).
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.
外科辅助快速上颌扩弓（SARME）是矫正上颌横向发育不足的一种常用治疗技术。本研究的目的是使用锥形束计算机断层扫描（CBCT）和正位头影测量片评估SARME术后鼻腔和腭部骨骼的变化。
在这项回顾性研究中，对14例上颌横向发育不足患者治疗前及SARME手术6个月后的影像学图像进行评估。在CBCT上测量鼻骨宽度和腭骨宽度的变化。在正位头影测量片上评估上颌基骨宽度、鼻腔宽度和角度测量值的变化。
在上颌第一前磨牙和磨牙水平测量鼻底宽度，SARME术后显著增加（分别为p = 0.005和0.017）。第一前磨牙和磨牙之间的腭骨宽度也显著增加（分别为p = 0.003和0.002）。上颌基骨宽度（p = 0.026）、鼻腔宽度（p = 0.024）和其他角度测量值也显著增加（p < 0.05）。
SARME术后鼻腔和腭部骨骼的横向尺寸增加。由于鼻底和鼻腔扩大，可能会改善经鼻通气。
