Abstract

Objective: The purpose of this study was to assess the pterygopalatine suture disarticulation pattern in the tomographic axial plane after treatment with midfacial skeletal expander (MSE). Materials and methods: Pre- and post-expansion CBCT records of 36 subjects (12 males, 24 females, mean age 20,14 years) who were treated with MSE (Biomaterials Korea, Seoul, Korea) appliance were analysed and compared using OneClinic 3D software. Reference planes were identified, from there calculate the distance and angle to evaluate the opening and displacement of the suture to the lateral side. Results: After MSE treatment, 37 sutures out of 72 (51,4%) presented openings between the medial and lateral pterygoid plates on both right and left sides. Partial split was detected with 13 patients (8 females, 5 males). The mean size of the opening was 1,24 mm for the right side and 1,15 mm for the left side. The lateral movements of the pterygomaxillary fissure and pterygoid process were observed. Conclusions: this study shows that pterygopalatine suture can be split by MSE appliance without the surgical intervention.
