Abstract
The aim of this retrospective study was to investigate the soft tissue changes after maxillary advancement in class III patients. Pre- and post-operative lateral cephalometric radiographs of 20 patients treated with maxillary advancement surgery were included in our study. Skeletal, dental and soft tissue measurements were performed by a single researcher using Dolphin Imaging software version 11.95 (Dolphin Imaging, Chatsworth, CA, USA). Paired t test was used for statistical evaluation and p < 0.05 was considered statistically significant. The amount of motion in soft tissues, respectively, are UL-E: 2.05mm, ST.A: 0.65mm, ST.B: - 5mm, ST.Pog: - 5.73mm, ST.Conv: - 3.95mm, nasal prominence: - 1.58mm, nasal height: 2.76mm and upper lip length: 2.22mm. The change of distance to horizontal and vertical reference planes are, respectively, Prn-HRL: 3.02mm Prn-VRL: 1.76mm Sn-HRL: 2.76mm Sn-VRL: 2.94mm ST. 3.74mm ST. 3.81mm UL-HL: 3.93mm UL-VRL: 4.57mm LL-HRL: 2.29mm LL-VRL: 5.31mm. It can be concluded that soft tissues related to maxilla moved anteriorly due to maxillary advancement.
