This case report describes a case in skeletal Class III malocclusion with asymmetry, maxillary skeletal expander (MSE) can be a compromised treatment option that successfully improves the occlusion. A 14-year-old female patient with facial asymmetry visited our orthodontic department, exhibiting left displacement of the mandible, severe crowding of the maxillary arch, shallow overjet and maxillary transverse deficiency. At the beginning of treatment, MSE was installed to expand maxillary transverse width. For unilateral expansion, the arm on the right side was removed after expansion to induce relapse. Afterwards, the rear arm was left without removing the MSE and was used for distal movement of the molars with the horseshoe application. In the mandible, the bi-dimensional wire and MEAW was applied. Appropriate use of MSE can achieve both unilateral expansion and distal movement of the molars.
