Description
Summary:The purpose of this study was to evaluate maxillary expansion, operative time and pain associated with a new minimally invasive surgical technique to treat maxillary hypoplasia in adult patients. Consecutive patients were included and prospectively analyzed. The technique consists in miniscrew-assisted rapid palatal expansion (MARPE), minimally invasive approach to maxillary osteotomies, latency period and activation period until the desired expansion. The parameters evaluated included operative time, treatment-related pain by the visual analog scale (VAS), and transverse maxillary expansion. The Shapiro–Wilk test was used to assess the normality of data distribution. A paired t-test was used to compare the data between T0 (preoperative) and T1 (postoperative – end of activation). The significance level was set at 5%. Eleven patients were included. Mean operative time was 24.11 min (14.4–32 min) and overall postoperative VAS score was 2.81 (0–9). A comparative analysis showed significant increases in maxillary width at the skeletal, alveolar, and dental levels (p
